A theory of sleep is proposed in which cerebral free radicals accumulate during wakefulness and are removed during sleep. Removal of excess free radicals during sleep is accomplished by decreased rate of formation of free radicals, and increased efficiency of endogenous antioxidant mechanisms. Thus, sleep functions essentially as an antioxidant for the brain.
提出了一种睡眠理论,即在清醒期间大脑自由基会积累,而在睡眠期间会被清除。睡眠期间多余自由基的清除是通过降低自由基的形成速率以及提高内源性抗氧化机制的效率来实现的。因此,睡眠本质上起到了大脑抗氧化剂的作用。
