Research reveals that stress hormones such as cortisol, will
increased risk to suffer from hypertension, heart disease, and so forth. It turns out
not only that, a recent study reported in the journal Psychoneuroendocrinology,
edition this December, said that stress hormones will also make the brain shrink.
High stress hormones will make your memory decline and the hippocampus (the part
brain) will shrink. Hippocampus is part of the brain that functions in the process
learning and memory.
The study was done by measuring cortisol levels in a group adults. Found, people who have high cortisol levels on a continual constantly tests your memory will have an even worse with the people who
have low to moderate levels of cortisol. In addition, a long exposure to high cortisol levels will make the hippocampus in the brain, shrinking as much as 14%. Maybe this can explain why in some parents show power remember as well as the ability to think the worst, while the other parent shows vice versa.
How does cortisol influence on children? The 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 adolescents who come from weak socio-economic groups showed levels higher stress hormone
than those from socio-economic groups are more able.
This shows that stress can affect brain function, regardless of 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 usual colds
to cancer. A 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), undermined the body's immune system. So, make you fall ill.
"Until now there is strong evidence of a link between the brain and the immune system. But at this moment we've got that connection, When stress, nerves release a lot of NPY. Hormone enter the bloodstream, where it inhabits hormone cells in the immune system and destroy pathogens in the body. That stress makes you sick now no longer a myth. That is reality and we need to deal with seriously. "said Fabienne Mackay Researchers from Australia
The findings were published in the Journal of Experimental Medicine on Monday.
The researchers suggested 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. But findings that hormone effects on the immune system has opened new doors for overcome 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 time
many years to develop drugs to deal with 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 relaxation,
best we can, "he said.
