Is Facebook bad for your mental health?


The internet and social media have mushroomed since the first email was delivered more than 40 years ago. Nowadays, in our technology-driven world, using the internet for instant communication is an integral part of modern life.
With around one in four people worldwide using social media sites such as Facebook, Instagram, LinkedIn and Twitter, this new way of communicating has eliminated the constraints of time and location, allowing people to share their lives and interact with others, no matter where they are.
Much has been written and said about the pros and cons of social media – not least in terms of mental health. Here’s what you should know.
What is social media?
Social media essentially refers to a range of websites that enable people to interact worldwide using discussion, photos, audio and video.
Facebook was the first social network to exceed one billion registered accounts, according to the latest data by global statistics portal Statista.
Its October 2014 statistics on leading global social networks ranked by number of active users (in millions) showed Facebook way ahead at 1.320 billion. This was followed by QZone (645 million), Google+ (343 million), LinkedIn (300 million), Twitter (271 million), Tumblr (230 million) and Tencent Weibo (220 million).
Social-media newcomers that are currently growing in popularity include Pinterest and Instagram.
How popular is social media?
Roughly 73% of online adults now use a social-networking site of some kind, according to the Pew Research Centre’s 2013 Social Media Update Project, which provides statistics updated to January 2014.
Report results are based on data from telephone interviews with 1 801 adults, aged 18 and older.  
Other interesting results from the report show that:
•    Many people don’t confine their online activity to one service, with approximately 42% of online adults using multiple social networking sites.
•    Usage among older people has also increased significantly. Some 45% of internet users, age 65 or older, now use Facebook – up from 35% in late 2012.
•    Women are more likely to use Facebook than men.
•    60% of Facebook users report going onto the site at least daily, while 40% log on multiple times per day. Other platforms such as LinkedIn and Twitter show similar frequency usage.
Impact on mental health
So, accepting that social media clearly plays an important part in our lives, how does it affect us and impact on our mental health?
According to Professor Jessica Vitak of the College of Information Studies at the University of Maryland, the relationship between social media and mental health is far too complex to suggest that it has blanket effects across users.
“We need to look at the context of use and individual factors such as existing mental state to begin to understand whether one’s use of social media will have a more positive or more negative effect,” she explains.
Regarded as an expert on social-media usage and its effect on people’s relationships, Dr Vitak’s master’s thesis entailed a survey of more than 600 Georgetown University undergraduates regarding their uses of various technologies, including Facebook, to interact with different members of their social networks.
Some researchers have suggested that using sites such as Facebook may exacerbate anxiety, reduce confidence and increase feelings of inadequacy. However, many of these studies – such as the poll by the University of Salford’s Business School on behalf of charity organisation Anxiety UK – involved fewer than 300 people.
Prof Vitak’s take is that social media is neither positive nor negative in and of itself. “What matters is what we’re posting, the features of a given site, and who we’re interacting with.”
What are the societal implications?
The Social Media and Society 2014 Conference held in Toronto in September 2014 focused on best practices for studying the impact and implications of social media on society, attracting leading social media experts and researchers from around the world.
“Common lore asserts that extensive adoption of social media results in increased alienation and more fleeting relationships within society,” commented keynote speaker Prof Keith Hampton, Associate Professor and Co-Chair of the Social Media Cluster at Rutgers School of Communication and Information.
However, his research found that “social media results in more persistent relationships and an increased awareness of the activities of one’s social ties through digital technology”.
Prof Hampton added that, with regards to stress and social media, women who use social media felt less psychological stress but more social stress, while men generally didn’t display any correlation between social-media use and stress (though they may feel some social stress when hearing about a friend’s demotion or interaction with a crime).
Professor Vitak’s own research echoes that of Prof Hampton in some aspects. She has found that, for many people, social media can provide social benefits in terms of social and emotional support and maintaining relationships that would have faded away without the technology.
She adds that social-media exchanges – such as birthday wishes or congratulatory messages after a major life event – may make people feel more connected to their social network and loved.
She concedes that, in some situations, social media use may be toxic for one’s mental health, as in the case of cyber bullying and online harassment.
“Like everything, social media in moderation can have positive benefits for users – people can stay connected to distant friends, share important life events with their network, as well as discover new ideas and information from total strangers,” Prof Vitak asserts.
Social media can be a source of tension
While Prof Vitak believes Facebook has the biggest potential to positively impact on the mental health of users, she remarks that it’s also the source of much tension because the site changes the way we interact with different groups of people.  
Known as “context collapse” – when social networks are “flattened” into a simple homogenous group such as Facebook friends – Prof Vitak says it “can cause problems in home or workplace relationships”.
These may include factors such as sharing content with an entire social network, even though a specific update may only be intended for a subset of the network, the availability of fewer social cues, which may lead to messages being misinterpreted, and the tendency to selectively portray primarily positive content about one’s life.
As we continue living in an increasingly networked world – and with social networking sites offering one of the most popular methods people currently use to connect with others – it seems clear that despite concerns about possible negative consequences to our mental health, social media isn’t going to disappear any time soon.
Tips from social-media experts
•    When you use technology, make sure it doesn’t detract from important relationships and responsibilities. If your child or spouse complains that you’re always on your smartphone, you may want to cut back and do more things that involve direct interaction.
•    If you start skipping work or college because you spent all night playing League of Legends, or if chatting on Facebook with friends means you’re unable to meet deadlines, you should re-evaluate your priorities – that is, if your job or studies are important to you.
•    If you feel worse after using a social-media site, you may want to change who you interact with, or decide whether you want to use the site at all.
•    It may be helpful to take “social-media vacations”, where you stop using a site for a period of time and then come back, or take breaks during the day by switching off devices.
•    If you’re being harassed on social-media sites and feel it’s negatively impacting your well-being, make sure you know what you can do to protect yourself. This could include measures such as reporting a person harassing you or blocking them.
•    If you’re a parent and are concerned that your child is spending too much time on social media, look for creative ways to encourage or even make it compulsory to ensure “off” time away from sites and devices.
•    Good sources to get help or more information include Netaddiction.com and Enough is Enough (EIE). Internetsafety101.org is an organisation that aims to make internet use safer for children and families.
Social-media addiction – cause for concern?
Too much of anything (in this case excessive use of social media), and the need to continually be connected electronically at the expense of mental wellbeing, have led to the term “technology addiction” or “internet addiction”. Even more contentious is the notion that it should be considered a medical disorder.
The nature of this perceived addiction varies, but it generally entails constantly checking instant messaging (IM) apps, frequently changing status updates and uploading “selfie”images on social-networking sites.
While some mental health professionals advocate including internet addiction as a DSM diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, others, like psychiatrist Dr Adrian Wang of Singapore’s Gleneagles Medical Centre, are against this.
He regards internet addiction as “more of a symptom of a larger problem – anxiety, depression, boredom, self-esteem issues, to name a few – than an illness itself”.
Dr Wang concedes that some individuals with addictive personalities may be more vulnerable to developing such an addiction, adding that a combination of factors – e.g. an addictive personality, access to technology from an increasingly young age, plus a trigger such as depression or anxiety – could make the habit snowball and develop into symptoms of full-blown addiction.
His sentiments on internet addiction are echoed by researchers at the London School of Economics (LSE) who conducted a study among European youths in November 2012. They used the term “excessive use” instead of addiction to describe patterns of “repetitive, compulsive and uncontrolled use”.
In their study, the LSE researchers commented: “Psychological approaches suggest that people use the internet excessively to compensate for social or psychological difficulties, and deficits in personal well-being in terms of their everyday offline life.
Studies have linked sensation seeking (a tendency to pursue excitement and sensory pleasure), loneliness and emotional problems (such as depression and low self-confidence) to excessive internet use.”
Dr Jessica Vitak says that with the dramatic shift to technology-based communication over the past century, “addiction” is a highly overused word. 
“Just because people are dependent on a technology – because it makes tedious tasks easier and provides entertainment and social connection – doesn’t mean they’re addicted in today’s world.”

16 strange laws from around the world


You’d be surprised to know what has been and what is currently against the law in some countries around the globe. Have a look at these rather odd laws:
USA
In Connecticut, it’s illegal to let someone copy your homework. The statutes explicitly prohibit selling essays, dissertations, etc. at any education facility supervised by the state. So, I guess it’s okay at private schools then?
In Florida, bar owners (or anyone who owns a commercial establishment where alcohol is sold, for that matter) could be fined $1 000 (over R11 000) if they permit or participate in dwarf-tossing contests. (We don't think that it's crazy that dwarf-tossing is illegal. It's crazy that it was prevalent enough so that a law had to be made against it. Seriously people. Dwarf tossing? No.) 
In Minnesota, any game in which participants attempt to capture a greased-up or oiled-up pig is illegal. We’re not sure why this is a thing.
I’m not going to Mississippi any time soon. Apparently, swearing in front of two or more people in public could get you sent to the chookie for up to a month - or you could pay a fine.
Thailand
No one is permitted to step on any form of the national currency as all bills and coins display a picture of the king’s face.
Singapore
Here, it’s illegal to walk around your own home naked, as it’s considered pornographic (yes, porn is also illegal). If you break this law, you could be fined or 3 months in prison. Oh, and if “a person who is clad in such a manner as to offend against public decency or order” is around, they will also be thrown in jail.
The sale of gum is also prohibited in Singapore. While it’s not illegal to chew gum, disposing of it improperly will get you a massive fine.
Cambodia
You can’t use a water gun when celebrating the New Year, as some participants used to fill it with sewage. The funniest part? If you’re found with a water gun, it will be confiscated, but that’s it. No jail time. No fine.
United Kingdom
In England, it’s legal for a male to urinate in public, as long as it’s on the rear wheel of his vehicle and his right hand is placed somewhere on his vehicle.
By law, all cab drivers still need to check with their passengers if they have smallpox or the plague.
A boy under the age of 10 is legally not supposed to ever see a naked mannequin. Oh the horror!
Throughout the whole of England it is illegal to eat mince pies on Christmas Day. At Christmas of all days?!
Canada
In Petrolia, Ontario, "yelling, shouting, hooting, whistling or singing is prohibited at all times." Shame.
All business signs in Quebec must be written in French, according to the law. If you want it in English, that’s cool, as long as the English sign is twice as small as the French one.
In Halifax, taxi drivers “absolutely cannot wear a t-shirt” according to this law.
Philippines
This is my favourite one so far. In the Philippines, an ‘annoying’ person can actually be fined for being annoying. The second paragraph of Article 287 states that “any other coercions or unjust vexations shall be punished by arresto menor (imprisonment for from one day to thirty days) or a fine ranging from 5 pesos to 200 pesos, or both.”

10 health benefits of eggs


Many people believe that eating eggs may be bad for your health. Here are some excellent reasons to justify why eating eggs can make you healthier, brainier, leaner and stronger. 
1. Eggs help to improve performance
Eggs have a high satiety index, meaning they make you feel full for longer. One large egg supplies 6g of high quality protein and a large variety of essential nutrients, with the exception of vitamin C. This is why teaming up a fruit or orange juice with an egg and whole-wheat/low GI bread provides the perfect breakfast to perform well in a challenging environment.
2. Eggs can help to iron out problems
Many people with mild iron deficiency experience vague symptoms of tiredness, headaches and irritability. Iron is the carrier of oxygen in the blood and plays an important role in immunity, energy metabolism and many other functions in the body. The iron in egg yolk is in the form of heme iron, the most readily absorbable and usable form of iron in food and more absorbable than the form of iron in most supplements. 
3. Eggs improve nutrient adequacy of the diet
The nutrient density of eggs makes them a valuable contributor to a nutritious diet. A study among egg vs. non-egg consumers revealed that the diets of the non-egg consumers were more likely to fall short of vitamins A, E and B12. Eggs contributed 10-20% of folate and 20-30% of vitamins A, E and B12 among egg consumers. This study demonstrates the important role one food can play in ensuring nutrient adequacy.
4. Eggs do not increase blood cholesterol 
In the 1990s, eggs received a lot of bad publicity due to their cholesterol content of 210mg per egg yolk. Numerous studies have clearly demonstrated the lack of a relationship between egg intake and coronary heart disease.
To put things into perspective, it is important to realise that foods high in fat, especially saturated and trans fatty acids have a far greater impact on heart health than cholesterol in food. Eggs should be recognised as an inexpensive, versatile and easily digestible source of protein.
5. Eggs can help to promote weight loss
Eggs with toast have a 50% higher satiety index than regular breakfast cereals. Several studies have reported that starting the day with an egg breakfast increases satiety in overweight people and may help with weight loss.
In one study where a breakfast of bagels, cream cheese and yoghurt were compared to a breakfast of two eggs, toast and jam (same amount of kilojoules), the latter group stayed fuller for longer and reduced their kilojoule intake at lunch by 29%.
At 315kJ per large egg, eggs actually add few kilojoules for all the nutrients they provide. When teamed up with whole grains (for example whole-wheat bread) and fruit or vegetables they are a complete meal, readily available, easy to prepare and inexpensive, making them a useful tool in weight-loss programmes. 
6. Eggs help to promote brain health
Choline is a nutrient that facilitates brain development in the foetus and newborn as well as memory function even into old age. Eggs are an excellent dietary source of choline, and one egg per day will provide 28% of a pregnant woman’s choline requirement.
Choline is of extreme importance during pregnancy and lactation when the reserves can be depleted. At the same time, it is the critical period for foetal brain development and lifelong memory enhancement. In experiments with rats, memory function in the aged rat was in part determined by what the mother ate. Mothers, the message is clear – make a lifelong investment and eat your eggs!
7. Eggs help to prevent cataracts and to protect eye sight
A good dietary intake of eggs, spinach and broccoli is associated with a significant decrease in cataracts (up to a 20% decrease) and age-related lens and retinal degeneration, the leading cause of blindness in the elderly (up to a 40% decrease).
Eggs are a good source of the antioxidants lutein and zeaxanthine, which play an important role in keeping the eyes healthy. It accumulates in the eye where these nutrients protect against some types of harmful, high-energy wavelengths of light. Getting enough lutein and zeaxanthine is therefore very important from childhood onwards throughout the life cycle.
8. Eggs provide the best quality protein
Protein is one of the most important elements of our diet. Our bodies use protein to build new and repair old tissue. Eggs are champions at providing high quality protein. Amino acids are the building blocks of protein. Nine of these amino acids cannot be manufactured by the body and must be derived from the diet. A complete protein food contains enough of these nine essential amino acids to promote growth and maintain body tissue.
Egg, milk and meat (including poultry and fish) proteins are all complete proteins, but egg protein is of the highest quality, with a rating of 100. Compared to eggs, milk is rated at 93 and fish and beef at 75. One egg has approximately the same protein content as 30g cooked meat, fish or poultry. And apart from being the most versatile and best source of protein in our diet, it is also the least expensive.
9. Eggs can help to protect our bones
Eggs are one of the few natural food sources of vitamin D, our sunshine vitamin. Vitamin D is essential for calcium absorption and for maintaining optimum bone health. Eggs therefore play a supporting role in the prevention of osteoporosis together with dairy products, our main source of calcium.
10. Eggs promote healthy hair and nails
The hair and nails reflect many biochemical imbalances and shortages in the body. Eggs can help to promote healthy hair and nails because of their high content of sulphur-containing amino acids and the wide array of vitamins and minerals.
Many people report faster growing hair after adding eggs to their diet, especially if they were previously deficient in foods containing zinc, sulphur, vitamin B12 and vitamin A.

If you can't smell these 5 things you might be about to die


Smell is usually considered one of the less essential senses compared to abilities like vision and hearing. However, a new study suggests that your sense of smell, or lack thereof, could be giving you clues about potentially catastrophic health issues.
The study used five aromas: peppermint, orange, fish, rose and leather. An inability to distinguish these scents was a strong indicator of death within 5 years. Those who failed to smell the scents were almost 6 times more likely to be dead within that timeframe, reported the Economist.
While the study, which was conducted by the University of Chicago and published in PLOS ONE, might seem to have a strange premise, there is strong scientific reasoning behind it. A poor sense of smell has been linked to a number of common medical ailments such as cancer, Alzheimer’s and Parkinson’s.  It s also associated with premature shortening of the telomeres which leads to accelerated ageing.
The study took 3005 participants aged between 57 and 85 and administered a simple smelling test. Depending on how many of the smells they could identify, participants were placed into one of three categories: normal, smell-deficient, or unable to smell.

A follow up study was conducted after 5 years, in which time 430 of the respondents had died. The deaths were then attributed to the appropriate categories from which the following breakdown was derived.

Normal smelling: 10% dead
Smell-deficient: 19% dead
Unable to smell: 39% dead.

These findings were then adjusted to account for age, socioeconomic status, gender and age after which the correlation was still found to be statistically significant.
The suggestion is not that the loss of smell is the causes of death, but rather that it is a sign of underlying health issues that are about to cause serious problems. It is posited that because smell requires a frequent turnover of stem cells, diminishing capabilities here are a result of the body’s overall inability to regenerate itself. This has a clear link to neurodegenerative disorders like Alzheimer’s, as well as cancer which is a result of the improper growth of new cells.
The researchers concluded that scent tests could form a valuable medical tool, especially in the field of geriatric care, say PBS.

This happens when you lie on your online dating profile


The last online date I went on was with a forty-something guy I was considered a 98% match with. According to his profile he was a well-travelled senior lecturer of two fascinating topics at a top South African university. According to his profile he was an out-doorsy type, with a devil-may-care approach to adventure and loving.
So that’s what I was expecting.
In reality? He was living with his parents, worked at the university for a semester, but was mostly jobless and penniless. He also had an Australian girlfriend who had dumped him not a month before and was nursing a broken heart and dream to get back together with her. Oh and he stayed indoors mostly due to a seeping rash that covered most of his body.
Good times. I paid my bill, went home and deleted my profile.
I was reminded of this when I saw the latest YouTube video gimmick from Simple Pickup, one of those pickup artist sites that teach men how to bag that chick etc etc.
They posted two videos, Fat Girl Tinder Date and Fat Guy Tinder Date, based on a rather spurious reference in a 2011 HBO doccie about online dating to an unnamed (and as yet, unfound) survey that stated: ‘In the online dating world, women are afraid of meeting a serial killer. Men are afraid of meeting someone fat.’
Now I have worried about crazy people, but have never thought I should worry about serial killers when choosing a potential mate from a dating site. Despite what mini-series would have us believe, our communities are not that populated by murderous psychopaths. Trolling sociapaths maybe. In fact, I’m way more concerned about how accurately my potential beau’s profile matches really real reality.
Because, mostly, what you see is rarely what you get.
So I was curious as to why the guys’ reaction in the Fat Girl Tinder Date was considered so appalling.
Let me explain. The basic set-up is this: A man and a woman set up a profile of themselves as themselves on dating app Tinder. In their profile pics they appear as well-built, very active beachwear-model types. They will then meet their matches – but not looking like themselves. Instead, they’ll don fat suits and their dates’ responses are recorded.
Now, let’s just quickly underline the fact that Tinder is an app that is based on the old ‘hot or not’ chestnut. It is practically a face catalogue to which you sometimes attach a chat. You are swiping left or right (pass or like), based on superficial information that is primarily all about looks.
So back to the video and the dates’ responses.
In a nutshell, for the Fat Girl Tinder Date the media soundbite went like this: The guys were sexist arseholes because they did not like what they saw and said as much; one lied about going to the bathroom, another asked the woman if she was pregnant … they were rude, mean and disrespectful.
Shock shock horror horror, guys are arseholes and stereotype women based on their looks. (Did I mention this was a Tinder date where BOTH sexes play tag with people on the same pretty scale?)
In the Fat Guy Tinder Date video, however, the women were lovely. They only mentioned that he didn’t look like his pics, still stayed and chatted nevertheless and even set up future meets.
Is this supposed to prove that women are just nicer and less superficial than men? Or that they’re just more polite about being lied to?
Before you answer that, here’s the interesting thing about their interactions that has nothing to do with looks. The ‘fat guy’ and the ‘fat girl’ had very different attitudes to the incorrect information they had supplied.  
Although the premise of the videos is the same, where ‘the fat guy’ admits his photo was at least a few years old and acknowledges this difference, ‘the fat girl’ pretends to have no idea what they’re talking about. She says the much skinnier pics of her were taken only a few weeks ago and asks her dates if it’s maybe just the angle of the photo that had them confused.
So now her dates are lied to and condescended to. Wouldn’t that piss you off? It would piss me off. Would you feel the need to be nice? If so, why?
I’m just curious as to why we applaud ‘niceness’ with complete strangers, when sometimes ‘fuck you, are you for real?’ might be a more appropriate response.

New Google technology to search bodies for disease


Google is exploring a way to search inside people's bodies for early signs of deadly illnesses such as cancer or heart disease.
Signs of medical trouble
A Life Sciences team at the special projects Google X Lab are experimenting with having "nanoparticles" hunt for signs of medical trouble in bloodstreams and then essentially report findings to sensors people could wear.
"This is still early-stage research, but we've done a number of promising experiments, so we're going to keep going," Google said in a description of the project.
Imagined applications include a test for enzymes given off by arterial plaques that are about to rupture and cause a heart attack or stroke, or a way to watch for cancer cells after surgery or chemo treatments.
Early detection is known to dramatically increase chances of successfully treating a number of life-threatening diseases.
Batches of specially crafted nanoparticles, each microscopic in size, could be swallowed in pills and then absorbed into bloodstreams where they would stick to targeted cells such as cancer.
Non-invasive detection
Magnetic qualities designed into nanoparticles allow them to be drawn to worn devices and counted using non-invasive detection methods such as light or radio waves, according to Google.
If successful, the technology could "help physicians detect a disease that's starting to develop in the body," the California-based technology titan said.
Google said that it would license the technology to companies interested in using it for medically approved diagnostics.
Google Life Sciences team innovations include contact lenses that measure glucose levels in tears to allow people with diabetes to track blood sugar, and eating utensils that cancel out trembling hands caused by diseases such as Parkinson's.
Google also last year formed a company called Calico with a mission to address problems of health and ageing by harnessing advanced technologies.
