在人体大脑中心有一个如同豌豆大小的内分泌腺体——松果体,它合成褪黑激素。褪黑激素分泌有明显的周期性变化,周而复始,与四季变化和昼夜交替的节律保持同步,光照抑制分泌,黑暗刺激分泌,这种“时间信号”起着生物钟的作用。因此,含有褪黑激素的药物便成了飞机旅行者对付时差综合征、白领职员削除精神紧张和失眠的“灵丹妙药”。科学家们最近发现,褪黑激素将成为人类健康长寿的良药。人体内的褪黑激素在青春期来临时达 In the center of the human brain is a pea-sized endocrine gland, the pineal gland, which synthesizes melatonin. Melatonin secretion has a significant cyclical changes, go round and start again, and the seasons change and alternate rhythm to keep pace, light inhibition of secretion, dark stimulation of secretion, this “time signal ” plays the role of the biological clock. As a result, medications containing melatonin have become the “panacea” for travelers on jet-travel to combat jet lag and white collar workers to remove stress and insomnia. Scientists recently discovered that melatonin will be a good medicine for human health and longevity. Melatonin in the human body arrives at adolescence
