If you doubt the importance of sleep, try going without sleep for a few days and see what happens. Actually, sleep is central to our well-being and the scientific evidence is piling up.
Along this line is new evidence that sleep reduces accumulation of DNA damage in cells. Sleep is vital to animal life and is found in all studied animals. Based on observing single neurons in live transparent fish during sleep and wakefulness, researchers concluded that if the organism doesn’t sleep, its nerve cells don’t “power down” and can’t efficiently perform DNA maintenance.
