Sleep, rest and recovery are essential for brain health. Adults require an average of 7 to 8 hours’ sleep, although this varies individually. The best way to improve sleep quality and assist in falling asleep is to maintain regular physical activity.
Sleep is often affected by both psychological and physical factors. Insomnia is a condition that primarily involves difficulties falling asleep, waking up during sleep or maintaining sleep. An insomniac suffers from chronic fatigue. Lacking time or willingness to sleep is not insomnia.
Sleep deprivation results in lack of alertness and attention, increasing the risk of errors and accidents. Fatigue also leads to difficulties in remembering, learning and creativity. Extended sleep deprivation can lead to memory loss.
Melatonin is a hormone produced by the pineal gland which is connected to regulating the circadian rhythm and the light-dark cycle. Light exposure impacts melatonin production, which varies between individuals and may change as we age.
Melatonin production may be affected by stress, irregular eating habits, smoking and alcohol.
Melatonin products are used to relieve jet lag and short term insomnia, as melatonin helps reducing the time it takes to fall asleep, helping your system synchronise with your circadian rhythm.
