Sleep hygiene education is a means of informing the patient about aspects of diet, exercise and environment that can influence sleep. For example, to promote sleep, stimulants such as caffeine, nicotine and alcohol should be avoided, regular exercise (although not immediately prior to bedtime) favours better sleep, and noise, light and excessive temperatures (hot or cold) should also be minimised in the sleep environment. Advice on avoiding daytime naps and adhering to a regular sleep schedule may also be part of sleep hygiene education.1 This technique is rarely used alone, but may be helpful when combined with other therapies.
