Sleep is a necessary restorative process for all aspect of our body functions. It allows our body to regenerate and recover, rebuild immunity and actively produce hormones.
Sleep is divided into REM (Rapid Eye Movement) and non-REM sleep. REM sleep occurs several times during the night and is associated with dreaming. It accounts for about 25% of normal sleep, coming in longer periods towards the morning. The rest of our sleep time is Non-REM, which consists of 4 stages from light sleep (stage 1) to deep sleep (stage 4).
Insomnia is a sleep disorder characterized by difficulty falling and/or staying asleep and waking up often during the night. The physiological result of insomnia is a feeling of being constantly tired, low energy during the day, poor concentration, irritability, mood disturbance and not feeling refreshed
when you wake up.
Melatonin is a hormone released in your brain that significantly contributes to regulating your sleeping cycle. This hormone also plays an important role in healing and gives anti-oxidant protection. Melatonin affects the sex hormone as well – too little may cause erectile dysfunction. If Melatonin isn’t being well produced in the body over a long period of time it can lead to insomnia
Insomnia has become a common condition for many people. Previously seen mainly in the elderly. It is now experienced by much younger people, possibly because of travelling, shift work, stress, hormonal disturbances (menopause, thyroid), overuse of medications and overuse of stimulants such as mobile phones, caffeine, alcohol and tobacco.
