Get Adequate Sleep
Getting seven to eight hours of sleep every night can help individuals prevent themselves from getting sick, as it can give their body time to fight off any virus that might be attacking their immune system. Not only does adequate sleep help fight off a cold, but it also increases an individual's resistance to catching one. Sleep deprivation may lower the immune system, making patients more vulnerable to infection and illness.
During a study of 153 men and women between the ages of twenty-one and fifty-five years old, subjects who slept for less than seven hours per night were 2.94 times more likely to develop a cold than those who slept for eight or more hours.
