Adequate sleep is necessary for physical and mental well being. Sleep is influenced by multiple factors such as physiological, psychological, environmental and sociocultural factors. Sleep hygiene refers to the habits, environmental factors, and practices that may influence the length and quality of one\'s sleep. It is rarely effective when used alone, particularly in those with severe or chronic insomnia, but it makes the basis for more specific behavioral intervention. It is usually a component of Cognitive Behaviour Therapy treatment programs for insomnia. So, the most important step in non pharmacological treatment is the institution of proper sleep hygiene, or good sleep habits.
