4 Ways That Heavy Social Media Use May Lead To Depression

How social media use is linked to depression and anxiety.

How social media use is linked to depression and anxiety.

The more young adults use social media, the more likely they are to be depressed, a new study concludes.

Those who reported checking social media sites more frequently had 2.7 times the chance of being depressed.

However, because of its design, the study can’t tell us that social media is causing depression.

Similarly it can’t tell us that depression causes social media use.

But there is certainly an association to be explained.

Ms Lui yi Lin, the study’s first author, said:

“It may be that people who already are depressed are turning to social media to fill a void.”

If high social media use does influence depression, the authors think there could be a variety of mechanisms:

Feeling worse in comparison to idealised representations of others (most people post photos of themselves happy and smiling and doing exciting things).
Wasting time in meaningless activities reduces mood.
Social media use could fuel internet addiction.
Being on social media could lead to cyber-bullying.

Professor Brian A. Primack, one of the study’s authors, said:

“Because social media has become such an integrated component of human interaction, it is important for clinicians interacting with young adults to recognize the balance to be struck in encouraging potential positive use, while redirecting from problematic use.”

Professor Primack concluded:

“All social media exposures are not the same. Future studies should examine whether there may be different risks for depression depending on whether the social media interactions people have tend to be more active vs. passive or whether they tend to be more confrontational vs. supportive.
This would help us develop more fine-grained recommendations around social media use.

The study was published in the journal Depression and Anxiety (Lin et al., 2016).

The Natural Dietary Add-On Found To Treat Anxiety and Even Major Depression

Anxiety reduced 20% on average by a common supplement.

Anxiety reduced 20% on average by a common supplement.

Omega-3 supplements reduce anxiety and even lower inflammation in healthy people.

A high quality study has shown that the supplement reduces anxiety by an average of 20%.

On top of this a new review of 13 separate studies containing 1,233 people has shown that omega-3 supplements can reduce symptoms of major depression (Mocking et al., 2016).

Professor Janice Kiecolt-Glaser, the anxiety study’s first author, said:

“We hypothesized that giving some students omega-3 supplements would decrease their production of proinflammatory cytokines, compared to other students who only received a placebo.
We thought the omega-3 would reduce the stress-induced increase in cytokines that normally arose from nervousness over the tests.”

The study recruited 68 healthy young medical students who were divided into groups, with half taking the supplement and others receiving a placebo.

Professor Martha Belury, one of the study’s authors, explained:

“The supplement was probably about four or five times the amount of fish oil you’d get from a daily serving of salmon, for example.”

The researchers had planned to test the effects of omega-3 on stressed people.

But, because of changes to the curriculum, the medical students were relatively relaxed during the study.

Professor Janice Kiecolt-Glaser explained:

“These students were not anxious.
They weren’t really stressed.
They were actually sleeping well throughout this period, so we didn’t get the stress effect we had expected.”

Despite this, those taking the supplements saw 20% reductions in anxiety, on average.

Professor Ron Glaser, another of the study’s authors, explained the measures and results:

“We took measurements of the cytokines in the blood serum, as well as measured the productivity of cells that produced two important cytokines, interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFa).
We saw a 14 percent reduction in the amounts of IL-6 among the students receiving the omega-3.
…anything we can do to reduce cytokines is a big plus in dealing with the overall health of people at risk for many diseases.”

Professor Belury concluded:

“It may be too early to recommend a broad use of omega-3 supplements throughout the public, especially considering the cost and the limited supplies of fish needed to supply the oil.
People should just consider increasing their omega-3 through their diet.”

The study was published in the journal Brain, Behavior, and Immunity (Kiecolt-Glaser et al., 2011).

Higher Wisdom Is Correlated With A Form Of Dance And Ancient Traditional Practices

Higher wisdom is correlated with these diverse activities.

Higher wisdom is correlated with these diverse activities.

Classical ballet has been linked to increased wisdom by a new study.

The research also confirmed that many varieties of meditation are linked to greater wisdom.

The link, the researcher shows, is down to how meditation reduces anxiety.

Dr Patrick B. Williams, the study’s first author, said:

“We are the first to show an association between wisdom, on the one hand, and mental and somatic practice, on the other.
We’re also the first to suggest that meditation’s ability to reduce everyday anxiety might partially explain this relationship.”

The meditators in the study performed different types of meditation, including:

Mindfulness
Buddhist
Vipassana

Those who practised classical ballet were included in the study almost on a whim.

The results showed that people performing all the different forms of meditation had greater wisdom.

Those practising ballet did not have as high levels as the meditators.

Still, the more ballet they did, the higher their levels of wisdom.

Dr Monika Ardelt, a wisdom researcher who was not involved with the project, said:

“That meditation is associated with wisdom is good to confirm, but the finding that the practice of ballet is associated with increased wisdom is fascinating.
I’m not going to rush out and sign up for ballet, but I think this study will lead to more research on this question.”

Professor Howard Nusbaum, one of the study’s authors, said:

“As we learn more about the kinds of experiences that are related to wisdom, we can gain insight into ways of studying the mechanisms that mediate wisdom.
This also lets us shift from thinking about wisdom as something like a talent to thinking about it as something more like a skill.
And if we think about wisdom as a skill, it is something we can always get better at, if we know how to practice.”

The study was published in the journal PLOS ONE (Williams et al., 2016).

How Virtual Reality Could Treat Depression

People experiencing depression had just 8 minutes of this innovative therapy three times.

People experiencing depression had just 8 minutes of this innovative therapy three times.

Immersive virtual reality therapy could soon be helping people with depression, a new study suggests.

The virtual reality therapy helped people to be less critical and more compassionate towards themselves.

This helped reduce their depression symptoms.

The study used an intriguing method to encourage people to be more compassionate towards themselves.

While wearing virtual reality headsets, people in the study comforted a virtual child who was crying.

As they did so, it appeared to respond positively to the compassion.

Then the virtual reality system gave them the impression they were in the position of the child.

They saw themselves comforting the child, except now they were on the receiving end.

Professor Chris Brewin, who led the study, said:

“People who struggle with anxiety and depression can be excessively self-critical when things go wrong in their lives.
In this study, by comforting the child and then hearing their own words back, patients are indirectly giving themselves compassion.
The aim was to teach patients to be more compassionate towards themselves and less self-critical, and we saw promising results.
A month after the study, several patients described how their experience had changed their response to real-life situations in which they would previously have been self-critical.”

The 15 depressed people who took part in the study repeated the 8-minute scenario three times, at weekly intervals.

Nine reported experiencing fewer depressive symptoms one month later.

Professor Mel Slater, who co-authored the study, said:

“We now hope to develop the technique further to conduct a larger controlled trial, so that we can confidently determine any clinical benefit.
If a substantial benefit is seen, then this therapy could have huge potential.
The recent marketing of low-cost home virtual reality systems means that methods such as this could potentially be part of every home and be used on a widespread basis.”

The study was published in the British Journal of Psychiatry Open (Brewin et al., 2016).

Lack of This Type of Sleep Linked To Emotional Distress

Disturbed sleep and the vicious circle that links it to chronic depression and anxiety.

Disturbed sleep and the vicious circle that links it to chronic depression and anxiety.

A lack of REM sleep may raise the risk of chronic depression and anxiety, a new study finds.

REM or Rapid Eye Movement sleep is when we dream.

REM sleep occurs throughout the night as we cycle up and down into deep sleep.

Typically a person might have six periods of REM sleep in a night separated by an hour or less.

During REM sleep it may be that critical emotional memories are processed and resolved.

Mr Rick Wassing, who is the study’s lead author, said:

“Previous studies have pointed to REM sleep as the most likely candidate involved in the regulation of emotions.”

If sleep is disturbed during these critical periods, it could leave emotional memories unprocessed and unresolved.

The research was carried out on a group of people in the Netherlands.

Some simply completed a survey, while others were invited into the sleep lab.

Both studies found that when people’s REM sleep was disturbed, they had more trouble getting over emotional distress.

As distress built up, it was more difficult for people to sleep and so the vicious circle continued.

The study’s authors concluded:

“The present findings suggest that hyperarousal can result from an inadequate resolution of emotional distress, which, in turn, is likely due to restless rapid-eye-movement sleep.”

Mr Wassing said:

“The possible solution would be to stabilize REM sleep.
But, whether this is true and whether cognitive behavioral therapy might help is for subsequent research to find out.”

Dr Janis Anderson, a psychologist who commented on the study, said:

“Complex interrelationships between sleep and mood, including clinical mood problems such as major depression and bipolar disorder, are well-known.
This continues to be an important area for research, but also one in which speculative suggestions to patients can easily outpace the evidence.”

The study was published in the journal PNAS (Wassing et al., 2016).

The Online Anxiety Therapy That Changes People’s Brains In 9 Weeks

The amygdala is an area of the brain vital to the processing of the emotions.

The amygdala is an area of the brain vital to the processing of the emotions.

After nine weeks of online therapy, people experiencing social anxiety disorder show distinct changes in their brains, new research finds.

Online cognitive behavioural therapy can reduce anxiety and change brain volumes in critical areas.

The study recruited people with social anxiety disorder — one of the most common mental health problems.

Brain scans compared their brains before and after the online treatment.

Activity in the amygdala and anxiety reduced after the online cognitive behavioural therapy in comparison to a control group.

Mr Kristoffer NT Månsson, one of the study’s authors, said:

“The greater the improvement we saw in the patients, the smaller the size of their amygdalae.
The study also suggests that the reduction in volume drives the reduction in brain activity.”

The amygdala is an area of the brain vital to the processing of the emotions.

Mr Månsson said:

“Although we didn’t look at that many patients, this work provides some important knowledge — especially for all the sufferers.
Several studies have reported that certain areas of the brain differ between patients with and without anxiety disorders.
We’ve shown that the patients can improve in nine weeks — and that this leads to structural differences in their brains,”

The study was published in the journal Translational Psychiatry (Boraxbekk et al., 2016).

Anxiety Is Linked To These Common Mental Health Problems By Neurocircuitry

Anxiety is a normal part of everyday life, but when anxiety starts to interfere with everyday life it can become a more serious problem.

Anxiety is a normal part of everyday life, but when anxiety starts to interfere with everyday life it can become a more serious problem.

Stress and anxiety have been linked to the same neurocircuitry in the brain as depression and dementia.

The new study suggests people need to find ways to reduce chronic stress or they could be putting themselves at increased risk of mental health problems.

Neuroscientists have found there is an extensive overlap between neurocircuitry for anxiety, depression and dementia.

Dr. Linda Mah, who led the study, said:

“Pathological anxiety and chronic stress are associated with structural degeneration and impaired functioning of the hippocampus and the prefrontal cortex (PFC), which may account for the increased risk of developing neuropsychiatric disorders, including depression and dementia.”

Experiencing anxiety is a normal part of everyday life.

But, when anxiety starts to interfere with everyday life, it can become a more serious problem.

Chronic anxiety has also been linked to problems with memory and other health difficulties such as metabolic and immune disorders.

A previous study by Dr Mah and colleagues found that anxiety doubled the risk of developing Alzheimer’s disease:

“Canadian researchers examined 376 people between the ages of 55 and 91 with ‘mild cognitive impairment’, and their chances of going on to develop Alzheimer’s disease
[…]
The results showed that for people with mild anxiety symptoms, the chances of developing Alzheimer’s increased by 33%, for those with moderate anxiety it was 78% and for those with severe anxiety, the risk increased by 135%.
While depression has already been identified as a risk factor for developing Alzheimer’s, this is the first study to implicate anxiety separately.”

Dr. Mah said:

“Looking to the future, we need to do more work to determine whether interventions, such as exercise, mindfulness training and cognitive behavioural therapy, can not only reduce stress but decrease the risk of developing neuropsychiatric disorders.”

The study was published in the journal Current Opinion in Psychiatry (Mah et al., 2016).

The Brain Training That Could Reduce Sadness and Anxiety

Brain scans showed that people who practised a difficult version of this task coped better with negative emotions.

Brain scans showed that people who practised a difficult version of this task coped better with negative emotions.

Computer training can change how the brain regulates emotional reactions, a new study finds.

Researchers have found that a simple attentional training task encourages the brain to ignore irrelevant information.

The task involves identifying whether arrows on the screen are pointing left or right.

At the same time people were asked to ignore other arrows on the screen placed there to distract them.

Brain scans showed that people who practised a difficult version of this task later coped better with negative emotions.

Dr Noga Cohen, the study’s first author, said:

“These findings are the first to demonstrate that non-emotional training that improves the ability to ignore irrelevant information can result in reduced brain reactions to emotional events and alter brain connections.
These changes were accompanied by strengthened neural connections between brain regions involved in inhibiting emotional reactions.”

Dr Cohen explained the results:

“As expected, participants who completed the more intense version of the training (but not the other participants) showed reduced activation in their amygdala — a brain region involved in negative emotions, including sadness and anxiety.
In addition, the intense training resulted in increased connectivity between participants’ amygdala and a region in the frontal cortex shown to be involved in emotion regulation.”

The researchers hope this could lead to new treatments, said Dr Cohen:

“It is our hope that the current work would lead to further testing and potentially the development of effective intervention for individuals suffering from maladaptive emotional behavior.
While acknowledging the limitations of this study, which was based on a relatively small number of healthy participants and focused on short-term effects of the training, this may prove effective for individuals suffering from emotion dysregulation.”

The study was published in the journal Neuroimage (Cohen et al., 2015).

Being Anxious Has An Upside, New Psychology Study Finds

Social threats are detected by the brain in just 200 milliseconds.

Social threats are detected by the brain in just 200 milliseconds.

The brains of highly anxious people process social threats differently than those who are more laid back, a new study finds.

Anxious people process social threats with the part of the brain responsible for taking action.

This could indicate that anxiety does not lead to ‘oversensitivity’ or paralysis.

Rather, it could help anxious people to take action sooner.

Naturally, in most people the brain devotes more processing to social threats than it does to benign occurrences, the research confirmed.

Social threats are detected by the brain in just 200 milliseconds.

Less anxious people use areas of the brain involved in face recognition.

The most threatening facial expressions, the researchers found, were an angry face making direct eye contact.

Dr Marwa El Zein, the study’s first author, said:

“In a crowd, you will be most sensitive to an angry face looking towards you, and will be less alert to an angry person looking somewhere else.

In contrast to previous work, our findings demonstrate that the brain devotes more processing resources to negative emotions that signal threat, rather than to any display of negative emotion.”

The study was published in the journal eLife (El Zein et al., 2015).

The Anxiety And Sleeping Drugs Linked to Dementia And Death

Drugs prescribed for anxiety, OCD, insomnia, post-traumatic stress disorder and other conditions linked to dementia.

Drugs prescribed for anxiety, OCD, insomnia, post-traumatic stress disorder and other conditions linked to dementia.

Benzodiazepines carry an increased risk of dementia and even death.

Benzodiazepines include drugs marketed under the names Valium, Ativan, Klonopin and Xanax.

These drugs are often prescribed for anxiety and other mental health issues such as OCD, insomnia and post-traumatic stress disorder.

Research has now repeatedly linked these drugs to dementia and Alzheimer’s.

(For more on how to escape anxiety without drugs, learn about my anxiety ebook.)

Dr Helene Alphonso, a psychiatrist and Director of Osteopathic Medical Education at Texas University, said:

“Current research is extremely clear and physicians need to partner with their patients to move them into therapies, like anti-depressants, that are proven to be safer and more effective.
Due to a shortage of mental health professionals in rural and underserved areas, we see primary care physicians using this class of drugs to give relief to their patients with psychiatric symptoms.
While compassionate, it’s important to understand that a better long-term strategy is needed.”

A recent study found that taking benzodiazepines for three to six months increased the Alzheimer’s risk by 32%.

Taking the drug for more than six months increased the risk by 84%.

Other studies have found comparable results.

Benzodiazepines may be particularly dangerous for older patients.

Older patients are more susceptible to injuries such as falls or accidental overdoses when taking the drug.

Dr Alphonso said:

“It’s imperative to transition older patients because we’re seeing a very strong correlation between use of benzodiazepines and development of Alzheimer’s disease and other dementias.
While correlation certainly isn’t causation, there’s ample reason to avoid this class of drugs as a first-line therapy.”
