It has been proven that sleep reinforces both learning and memory. It helps our brain to function at higher speed and with greater processing. It also replenishes our lost energy and aids the body in both energy consumption and chemical breakdown. When a person is awake, they are constantly using up the energy that is given them at the start of each day. While sleeping, most of our organs are able to rest and thereby restore their natural energy. Our tired muscles get a re-deposit of energy and they use that energy to repair any damage that has been done during the day. Sleep is indeed required for general health and ongoing survival. That is why sleep treatments can be so important.
