Sleep hygiene refers to the general rules of behavioral practices and environmental factors that are consistent with good quality sleep. Several studies reported that a program combining sleep hygiene education with cognitive behavioral exercises is an effective method of non-pharmacological intervention for patients with insomnia, but there is insufficient evidence to support that sleep hygiene alone is an effective treatment. Shift work often has a negative impact on health, safety, quality of life, and work performance. Sleep hygiene practices can be helpful in shift workers. A prophylactic nap before night work can be beneficial in attenuating alertness and performance deterioration and decreasing the risk of accidents.
