All living creatures have times in their cycle when they shut down their metabolic activity for healing and repair to take place. In humans we call this sleep. During the flu epidemic after the First World War, a few sufferers developed neurological damage in which they lost the ability to sleep. All were dead within two weeks – this was the first solid evidence that sleep is an absolute essential for life. Happily the body has a symptom which tells us how much sleep we need. It is called tiredness – ignore this at your peril! During sleep we heal and repair, during our waking hours we cause cell damage. If there is insufficient sleep, then the cell damage exceeds healing and repair and our health gradually ratchets downhill. Lack of sleep is a major risk factor for all degenerative conditions from heart disease to cancer and neurological disorders.
