The immune system is an essential part of anyone’s good health. This is especially true for those who have any type of chronic medical problem. When you don’t get the quality sleep your body needs, the immune system is one of the first to be compromised. Obviously this is a bad thing since it is in control of fighting off all types of infection and bacteria. If you don’t try a sleep aid (preferably an all-natural product), you will find yourself sick more often on top of the general lethargy that goes along with a lack of rest.
