Although each person is different, infants grow fetal toxins. In addition, when women are anxious and irritable, there should be other reasons affecting emotions besides hunger. Japanese brain scientist Mr. Kaisei Yamaoka said: "The reason lies in serotonin, a hormone that is secreted when feeling stressed. Although each person is different, in general situations, people with more serotonin will feel emotionally calm, while those with reduced serotonin will feel restless and uneasy. In addition, stress can cause a decrease in serotonin, so the stress caused by hunger can make people feel irritable." Mr. Kaisei Yamaoka further explained: "Although we cannot definitively say that women have less secretion of serotonin, compared to men, it can be said that women are more easily affected by a decrease in serotonin. For example, if the boyfriend says something inappropriate at this time, it will make the girlfriend angry." In addition, Mr. Kaisei Yamaoka pointed out that being unhappy for a long time can lead to serotonin depletion, so eating some delicious food in advance can help restore the amount of serotonin in the body. Finally, Mr. Kaisei Yamaoka reminded men: "Take the opportunity to praise your girlfriend or give her some sweets as a gift, which will help increase the secretion of dopamine in women's bodies and allow her to feel more happiness." It seems that the main reason for women's capricious and spontaneous young lady personality is due to hormonal secretion. So gentlemen, please understand the "culprit" clearly and be more understanding and tolerant. (Editor-in-Charge: Teng Xiaolan)
