Sleep is not just a matter of closed eyes and "switching-off" for the night. It's actually an active process that involves increased metabolic and brain activity. There are two main phases of sleep. dream sleep (known as Rapid Eye Movement, or REM), and non-dream (non-REM) sleep,

Dream sleep is essential for humans. The brain is highly active at this time even though the body is not moving.

However, people with sleep disorders such as Obstructive Sleep Apnoea (OSA - one of the most common sleep disorders) will experience disrupted sleep and overall poor sleep quality. People who have OSA or other sleep disorders will suffer from the symptoms of sleep deprivation: poor memory, poor concentration, high blood pressure, and irritability. They are also at risk of more long-term health consequences, such as heart disease, stroke, and sudden death in sleep.

If unsure, always check with a doctor to investigate the cause behind poor sleep quality and sleep deprivation.
