Over the last 36 years patients have asked me how much sleep do I need? Many continue saying my body does fine with five hours of sleep I’ve been doing that for the last 50 years and I feel great. Well my answer has nothing to do with feelings, it has to do with physiology. All healing in the body is done when you are asleep during the day your body is constantly being broken down — it’s what we call catabolic. In the night when you are sleeping, that is when the cells are repairing and regenerating — it is what we call anabolic. Sleep studies have shown that the ideal amount of sleep is approximately 9.5 hours per day or more. Einstein said he needed more than this to function and allow his mind the capabilities it had. So start working to get more sleep, and most importantly more pre-midnight sleep, which has a one and a half bonus effect.
