Sleep
deprivation and unhealthy food intake suppresses immune system function. Or,
as Balachandran puts it, “The more all-nighters you pull, the more likely you
are to decrease your body’s ability to respond to sickness and bacterial
infections.” Our immune system is designed
to protect us from colds, flu,
and other ailments due to lack of balance of having correct sleeping time and
diet immune system will be low.
