Stress Causes Brain shrinking
Living in a state of stress was not only able to affectthinking ability and memory because the brain shrinks, but also make the durability body disease gets worse and facilitate entry into the body. Previous studies revealed that stress hormones like cortisol, will increase the risk for hypertension, heart disease, and so on. It turns out not only that, a recent study reported in the journal Psychoneuroendocrinology, December issue, saying that the stress hormones will also make the brain shrink. High stress hormones will make the memory decline and hippocampus (the part brain) will shrink. Hippocampus is part of the brain that functions in the process earning and memory. Research carried out up to 6 this year, measuring the cortisol levels in a group adults. Found, people who have high cortisol levels on a continuous will constantly have a memory test that is worse with the people who have low to moderate levels of cortisol. In addition, a long exposure to High cortisol levels will make the hippocampal region in the brain, much smaller 14%. Perhaps this may explain why some parents show power remember the bad and thinking skills, while other parents showed vice versa. How does cortisol influence on children? Researchers found, increased cortisol temporarily affect the ability of thinking and memory, but this only happens temporarily anyway. Other studies have shown that children and teenagers who come from weak socio-economic groups showed levels higher stress hormone than those from socio-economic groups are more capable. This shows that stress can affect brain function, without looking at age. And stress can occur in all age groups will affect the physical or mental sufferer. Meanwhile, another study conducted by researchers from Australia to prove that no scientific link between emotional stress and pain. Starting from the common cold to cancer. Group of researchers from Gervan Institute, Sydney, last week, announced they found a hormone that is released into the body when people are stressed, namely neuropeptide Y (NPY) subverts the immune system. So, make you fall ill. "Until now there is strong evidence of a link between brain and immune system. But at the moment we have to get that connection, When stress, nerves release a lot of NPY. The hormoneenter the bloodstream, where it inhabits hormone cells in the immune system and destroy pathogens in the body. That stress makes you sick is no longer a myth. That is reality and we need to take it seriously. " said Fabienne Mackay Researchers from Australia The discovery of the group was published in the Journal of Experimental Medicine on Monday. The researchers said they hope their work will produce two types of therapeutic intervention. Herbert Heerzog one of the other scientists, suggests neuropeptide Y has been known to affect blood pressure and heart rate. Yet findings of the impact of hormones on the immune system has opened new doors forovercome various diseases.
"Stress makes you more vulnerable when you, such as the flu, and even in situations more serious, like cancer. Hormones that can make the pain became more severe in this situation, "he told ABC Radio.
Other diseases linked to stress, among others rhematoid arthritis, multiple scelerois, Crohn's disease, type 1 diabetes and lupus. Mackay explains, it takes years to develop drugs to counter the influence of NPY. The best solution for the short term is to combat their stress. "The best thing to do is eliminate stress from our lives by reorganizing the way we live. Changing our lifestyle and use a variety of ways, such as yoga and relaxatio
