Many people do not get enough sleep. This is one of the most important aspects of a healthy immune system. When your body is rested, it is able to properly regenerate itself and build immunity. People today are constantly on the go and they have to work hard all day just to get some shut eye. Not giving our bodies the time to rest would definitely hamper its ability to fight off diseases.
Another way to get a better night's sleep is to go for a walk in the evening or during the weekends. Exercise releases endorphins into our bodies, which gives us a feeling of well being and a general feeling of happiness. When our immune system is strong, we are not afraid of diseases because we know we can fight them.
