How can i help prevent a cold?

Difficult: It is difficult to prevent a cold per se, the best way to decrease the chances you will catch a cold is to lead a healthy lifestyle. Eat a healthful, balanced diet, get plenty of rest, stay well hydrated and reduce stress through regular exercise or relaxation techniques. Some swear by zinc, echinacea or vitamin c based products, however, there is no supporting peer-reviewed research to validate.

Handwashing: The only real way to prevent a cold is to stay away from all other human beings during cold season. Since that's neither possible nor desirable, the next best thing is to wash your hands frequently when a cold is circulating, and not get too upset when it happens.
