HEALTH - Stress is proven to affect your health, both physically and mentally. However, to stress in small doses of short duration, such as before the start of a big presentation or thinking about work deadlines, it was actually pretty good condition.
Researchers at UC Berkeley to try to understand how stress can promote a good thing in the body.
They studied the effects of stress on mice in the laboratory and specifically look at the growth of stem cells in the hippocampus, or a part of the brain involved in the stress response, learning, and memory.
When the rats exposed to stress during a short period, they grew stem cells. When the condition is re-evaluated one week later, the researchers looked at mice have improved memory and learning function.
However, when the mice experiencing stress in the long term, the stem cells they do not grow, thus making the brain cells less.
Researchers believe, in small doses and short, stress can encourage the growth of stem cells into new cells in the brain, which in turn improves memory and learning ability.
"Our research shows that stress in moderate doses, ie mild stress and in the short term, can increase alertness, performance, and improve brain memory," said Daniela Kaufer, lead researcher and professor at UC Berkeley.
Of course, just like rats, too much stress in humans can cause major problems. Problems can be started from frequent headaches, overeating, depression to other illnesses.
"The ability of someone to manage stress can vary, so mild or severe depending on each person. However, good stress management can make even the large stress more manageable and do not cause much harm, "said Kaufer.
