"When there is insufficient amount of this hormone becomes more impulsive woman, she can take inappropriate decisions, take it out on others, it becomes more prone to emotional breakdowns and depression", - stated the scientists.
Experts recalled that serotonin called "hormone of happiness", actively produced during intimacy. In addition, an increase in its levels in the body may contribute to some foods: chocolate, nuts, fruits and vegetables are brightly colored, oatmeal, eggs, poultry, etc.
