Sleep is as important to your health as diet and exercise. Without enough sleep, it's impossible to live your life to its fullest.
By the most basic definition, anyone who doesn't get enough quality sleep has a “sleep disorder” – a broad term that is used to identify a range of problems.

Sleep problems have many causes:

• It could be a problem with your airway and/or your breathing, such as snoring and obstructive sleep apnea.
• It could be a problem with the way signals travel to and from your brain, such as narcolepsy.
• It could be a condition that causes uncontrollable leg movements at night – that is, restless legs syndrome.
• Or it could be one of the many problems that lead to insomnia, such as stress.
