Do your eyelids feel heavy during afternoon meetings? Do you sleep extra hours on weekend mornings? Do you use caffeine to stay alert? An alarm to get out of bed?
These are all symptoms of sleep deficiency--signals that you are operating below your peak performance and beneath your mental capacity. Despite popular perceptions, sleep is not a luxury--it is a necessity. More than seventy million Americans are sleep-deprived, and make crucial business and personal decisions in an impaired state. In Power Sleep, Dr. James B. Maas, a pioneer of sleep research at Cornell University, has created an easy, drug-free program to improve your body and mind for an alert and productive tomorrow.
