We Are the "Underslept"

[CoastWatcher]

""Human beings are the only species that deliberately deprive themselves of sleep for no apparent gain. Many people walk through their lives in an underslept state, not realizing it." Those are the words of Matthew Walker, Center for Human Sleep Science at the University of California, Berkeley. He points out that lack of sleep — defined as six hours or fewer — can have serious consequences. Sleep deficiency is associated with problems in concentration, memory, the endocrine, and the immune system - it may even shorten life span.
