Study is very hard on your eyes. Books, screens and notes all tire your eyes. One way to relax your eyes is hydrotherapy. Get a bowl of hot water (not too hot) dip in a washcloth then hold it gently against your eyes for 30 seconds. Then do the same with another cloth in ice cold water, or an ice pack. Alternate the hot and cold, each for 30 seconds, for three minutes. This helps relieve your eyes and is relaxing for you generally.
