Brain training helps to increase confidenceconfidence

Healthy eating, exercise and being active socially, are factors that may contribute to raising self-esteem. For some of us, this road is much more challenging, but as it is suggested by the researchers, brain training can help increase self-confidence as well in these cases.

The researchers suggest that manipulating brain activity can enhance self-esteem. Recent studies have identified patterns of brain activity that can predict the state of our self-esteem, what is more, the brain activity in this area, and we can interfere it. Self-confidence is defined as the belief in our abilities, an internal state which consists of what we think and what we feel about ourselves. Low self-esteem can lead to the shyness, anxiety, problems with the ability to be assertive and communication, influencing many aspects of our lives, including increased risk of mental health concerns like depression or bipolar disorder. Recent research suggests that the relevant brain training techniques based on methods borrowed from artificial intelligence, can change its activity, and thus stimulate our confidence. The study’s authors believe that this discovery could be a step towards the development of new ways to improve self-confidence, but also in the treatment of many mental states.

ptsdSleep can help alleviate the symptoms of PTSD

According to the latest findings, sleep in the first 24 hours after a traumatic event can help people efficiently process memories, and thereby minimize the symptoms of PTSD.

A traumatic event is a situation that can lead to long-term stress, an example of which is post-traumatic stress disorder (PTSD). It can be associated with the response to the current challenging events such as sudden death of a loved one, accident, rape or assault. According to estimates, 7-8% of people in the world, at some point in their lives experiencing PTSD, and the disorder is the most common among war veterans. Usually, the negative emotions associated with traumatic experiences for their disappear need sufficient time, but in the case of PTSD, sometimes the same time is not enough, because people who have post-traumatic stress disorder may experience flashbacks, nightmares and seemingly illogical fears for many months and even years after the event. Scientists from Zurich have discovered, however, that the beneficial sleep after a traumatic event can help overcome with the emotional reactions and memories more effectively. The study showed that memories after sleep are less intense and annoying, which allows to some extent protect ourselves against the effects of PTSD. Sleep can become therefore a natural help of early prevention of post-traumatic stress disorder in patients after difficult transitions.

low-carb-dietShort-term low-carb diets are more effective at weight loss than low-fat diets

Researchers at Mayo Clinic have shown that low-carb diets used in a short time, are much more efficient in losing weight than low-fat diets, in particular for people who suffer from insulin resistance or have lower blood sugar levels.

Modern diets, which are used for rapid weight loss are often extremely misleading. Scientists say that the definition of the low-carbohydrate diet is varied, and the evaluated diets contained from 4 to 46% of daily calories from carbohydrates. Doctors, therefore, recommend eating “real food,” and while reducing body fat work best short-term low-carb diets that are safe and efficient to contribute to reducing weight. During clinical studies has been shown that low-fat diets do not give quick results, and often leaned on processed foods, which may have some harmful effects on health. Low-carb diets used for short periods, have no side effects in the form of impact on blood pressure, blood glucose and cholesterol, and can provide faster weight loss satisfaction, motivating the introduction of the principles of healthy nutrition permanently. With the long-term diets, however – the low-carb and low-fat, the effects are similar.

noiseSensitivity to the noise is associated with changes in brain function

The extent to which the sounds of everyday life impact on us affects how the brain processes the volatility of the audio stream, and thus how we operate. Some people experience severe discomfort caused by sounds and suffer from noise.

Research has shown that harsh sound is doing various adverse effects on our health including causing sleep disorders and heart disease. It is interesting also that the sensitivity to noise may be rooted in our DNA. The newly published work of scientists showed that the auditory system of people allergic to noise is less sensitive to the new features of sound, which is apparently contrary to our intuition. Individuals with sensitivity to noise may have a problem with the building of forecasts concerning changes in the sounds. This reaction protects them from the unknown sound, but it can affect the functioning of the brain. Further studies on this subject are still needed, and it is not known yet whether for such a state of things is responsible contractions of the brain or another factor.
