Women are more sensitive to stress than men
Women’s brain is more sensitive to the action of a hormone that orchestrates the body’s response to stress, according to a new study in Philadelphia (USA). Men, however, neurons can adapt to resist its effects.
Women’s brain is more sensitive to the action of a hormone that orchestrates the body’s response to stress, according to a new study in Philadelphia (USA) and published in the journal Molecular Psychiatry. Men, however, neurons can adapt to resist its effects. To conduct their research, the scientists used male and female specimens of rats, exposed to situations where stress and then measured their levels of brain activity. Thus, a team led by Rita Valentino neurons found that females are more sensitive to the molecular signals emitted by a hormone called corticotropin releasing factor (CRF). This hormone, discovered in the eighties, is responsible for initiating the stress response.
Thus, by having more receptors for this substance, female neurons are more likely than men to react and trigger the stress process. Although the study was conducted in rodents, neuroscientist Rita Valentino, the lead author of the study, says that helps explain why women are twice as likely to suffer stress than men .
On the other hand, Valentino and his colleagues have discovered that, when subjected to chronic stress, males adjust their brain mechanisms for coping with stress more efficiently, reducing the number of CRF receptors, and therefore become less sensitive to hormone and more resistant to pressure situations. In female rats do not.
Stress Treatment
When a person realizes he is doing two things at once is stressful. The complete agenda, the rush, belts, shocks, repeated violent emotions, family fights, the disappointments, financial problems, overwork, and many things in life that can avoid stressors.
Set goals too ambitious and could not be fulfilled is stressful, it is then necessary to reschedule the life out of this vicious circle that can kill.
Stress can be normal and not cause any adverse effect when there is any trouble or anything that threatens the physical or life threatening. In these cases it is healthy because it helps the body prepare for the fight, to defend themselves or flee. Read the rest of this entry »
