New Delhi, Feb 21 (IANSlife): A good nights sleep is extremely significant to our health. If you do not get enough sleep, or sleep at an incorrect time, or sleep in breaks or have been diagnosed with a sleep disorder, this may cause sleep deficiency.

Quality sleep helps regulate a healthy immune system as well as hormones Ghrelin and Leptin that help balance appetite. On average, an adult should sleep for at least seven-nine hours.

The body's blood pressure is permitted to regulate itself through adequate sleep. It is essential in promoting heart health, muscle repair, cognitive consolidation and limits the onset of sleep disorders. Due to our current lifestyles, we might face trouble sleeping at night; we tend to ignore the signs until the problem escalates.

"Sleep disorders are a group of conditions that affect the aptitude to sleep well on a regular basis. It is a common problem nowadays that coincides with a simple headache and day-to-day stress. When a patient walks in for a headache which is a common neurological disorder, 60-70 per cent of the time it is related to disrupted sleep," says Dr Rima Chaudhari, Consultant Neurologist, Fortis Hospital, Mulund.

Insomnia is known to be the most common sleep disorder, But, there are more sleep disorders one should know of.
