A good night's sleep has immediate benefits for your energy and sense of wellbeing the day after. But in the longer term, sleeping well is an important factor in both mental and physical health.

According to the American Academy of Sleep Medicine, as many as 10% of adults suffer from chronic insomnia. Insomnia is characterized by an inability to fall asleep or stay asleep, or to fall into deep sleep. Sleep is crucial for virtually all functions in the body and brain to repair for optimal function. As a result, insomnia causes many undesirable effects. Among them are poor concentration, lower immune function and higher rates of anxiety and depression.
