Here’s Why Sleep Deprivation Makes You Feel Zoned Out

Why sleep deprivation feels like being drunk without drinking anything. Sleep deprivation disrupts communication between brain cells, new research finds. These disruptions can lead to temporary lapses in memory and even hallucinations. This helps to explain why sleep deprivation leaves people feeling so spaced out. Professor Itzhak Fried, who led the study, said: “We discovered that starving the body of sleep also robs neurons of the ability to function properly. This paves the way for cognitive lapses in how we perceive and react to the world around us.” The study

The Diet Linked To Higher Depression Risk

The longer people follow this diet, the more depressed they are. Vegetarians are twice as likely to experience depression as those eating a regular balanced diet, a new study finds. The longer people followed a vegetarian diet, the higher their depression scores, the researchers found. It is possible that the link is down to poor nutrition. Vegetarians typically have low levels of vitamin B12 in their diet. Indeed, around 50% of vegans have a vitamin B12 deficiency, while 7% of vegetarians have the deficiency. Vitamin B12 is found in red

The Laidback Sign Of Intelligence And Creativity

Both creativity and intelligence could be linked to this relaxing activity. Being a daydreamer is a sign that you are intelligent and creative, new research concludes. The result comes from a study in which over 100 people had their brains scanned while they stared at a fixed point for five minutes. The researchers wanted to see how their brains worked in unison when they were given nothing in particular to do. People whose brains worked more efficiently had greater intellectual abilities and also reported more daydreaming in their everyday lives.

5 Elements of Western Diet Linked To Alzheimer’s Disease

Study tests if western diet contributes to the risk of developing Alzheimer’s disease. Poor diet and inactivity probably account for around one-quarter of cases of Alzheimer’s disease, recent research finds. Now, a new study suggests that a ‘western diet’ may well be a contributing factor to Alzheimer’s. The study’s authors describe the typical western diet: “A western diet tends to include highly processed, less expensive fast food, that has a high fat content and simple carbohydrates while lacking essential nutrients from complex grains, fruits and vegetables.” Scientists at Tufts University

This Natural Juice Helps Keep Your Brain Young

Older brains can perform like younger ones with this supplement. A beetroot juice supplement can make older brains perform like younger ones, new research shows. The supplement was given to older adults just before they worked out. Professor Jack Rejeski, a study co-author, said: “We knew, going in, that a number of studies had shown that exercise has positive effects on the brain. But what we showed in this brief training study of hypertensive older adults was that, as compared to exercise alone, adding a beet root juice supplement to

8 Fascinating Facts About Anxiety Worth Knowing

Surprising facts about anxiety include that it affects the sense of smell and balance, how we judge faces and perceptions of our personal space, and more… Anxiety can be crippling in excess, but it does exist for a good reason. Anxiety tells us we’re in danger and we need to do something. It was our anxious ancestors who prepared better for winter and made plans to fight off neighbouring tribes. The relaxed, laid-back guys never made it. But anxiety’s effects aren’t limited to motivation, they seep through the mind to

The Common Pill That Sadly Lowers Women’s Wellbeing

The Common Pill That Sadly Lowers Women’s Wellbeing

Women reported lower mood, self-control and energy. The most common form of the contraceptive pill lowers women’s wellbeing, new research finds. Women who took a combination of ethinylestradiol and levonorgestrel — a common combination — reported lower mood, self-control and energy. This was in comparison to a control group given a placebo. Dr Niklas Zethraeus, the study’s first author, said: “Despite the fact that an estimated 100 million women around the world use contraceptive pills we know surprisingly little today about the pill’s effect on women’s health. The scientific base

Single Or Married: Which Is The Most Fulfilling Life?

Single Or Married: Which Is The Most Fulfilling Life?

Psychologist challenges the orthodox view with evidence from studies conducted over 30 years. Single people are more likely to experience psychological growth and development than those who are married, a psychologist claims. This is just one perk of being single which is often ignored. Others include greater sociability and resilience. The conclusions come from surveying 814 studies conducted over 30 years. Dr Bella DePaulo, addressing the American Psychological Association’s 124th Annual Convention, said: “The preoccupation with the perils of loneliness can obscure the profound benefits of solitude. It is time

The Type Of Daydreaming Linked To A Smarter Brain

The Type Of Daydreaming Linked To A Smarter Brain

Some types of mind wandering may be highly beneficial to our brains, and our futures. Intentional daydreaming is linked to a thicker cortex (a good thing) in certain key areas of the brain, new research finds. Directing the mind to wander is a cognitive skill that can be beneficial in some contexts. For example, it can allow us to mentally rehearse upcoming events, or solve problems we might encounter. In other words, it allows the brain to work out possible futures for us. So, mind wandering is not always a

The Emotion That Does Change People’s Behaviour After All

The Emotion That Does Change People’s Behaviour After All

Plus: four ways the effect of this emotion on behaviour change can be increased. Fear really can change people’s behaviour, a new review of the research finds. It was thought that using fear might produce a backlash effect — but this is not the case. Women are particularly susceptible to behaviour change by fear. Appeals which evoke fear are frequently used in all sorts of messages aimed at the public. For example, fear is used to try and stop people smoking or to support certain political policies. It is perhaps

10 Common Signs Of Anxiety Disorders Everyone Should Know

10 Common Signs Of Anxiety Disorders Everyone Should Know

The common signs of anxiety disorders are both psychological and physical. Anxiety comes in many forms, but all the different types often have certain core features. Like many mental health problems, almost everyone experiences anxiety from time-to-time. Whether it is a problem all depends on the amount and nature of the anxiety. Everyday anxiety in response to stressful events is normal, but severe anxiety in response to relatively minor events can be seriously disabling. Bear that in mind when reading the signs of anxiety. For example, a lot of people

Why So Many College Students Have Risky Sex on Spring Break

Why So Many College Students Have Risky Sex on Spring Break

My university, like many schools around the country, is on spring break this week. A lot of students are using this opportunity to not just take a breather from their studies, but also to travel. As I’m sure you’re well aware, spring break trips have a reputation for getting a little wild and crazy—I mean, just look at how they’re depicted in Hollywood films. But why is that exactly? What accounts for why so many college students partake in risky behaviors—especially risky sexual behaviors—at this time of year? Let’s take

The Secret To Emotional Control Most People Don’t Know

The Secret To Emotional Control Most People Don’t Know

Better emotional control is linked to lower levels of depression and anxiety. The key to healthy emotional control is to be flexible, new research finds. People with lower levels of depression and anxiety tend to vary their emotional control strategy successfully depending on whether the situation can be explained. Dr Peter Koval, one of the study’s authors, said: “Our results caution against a ‘one strategy fits all’ approach, which may be tempting to recommend based on many previous findings regarding reappraisal as a strategy for regulating emotion. Simply using any

The Scientific Way To Choose A Profile Picture For Dating, LinkedIn And Facebook

Let’s face it, many people seem to have no clue how to pick their own profile picture. You should let someone else choose your online profile picture, new research suggests. The advice is sound whether it is for a dating profile, LinkedIn, or just for Facebook. Other people pick more flattering profile pictures for us than we select for ourselves, it emerges. Others seem to know better which pictures make us look more attractive, competent or trustworthy — whichever the context requires. Dr David White, the study’s first author, said:
