Melatonin is produced in the Pineal gland located in the brain. This gland forms part of the Body’s endocrine (hormone) system and synchronizes the body’s circadian rhythm. The most well-known purpose of the circadian rhythm is the wake/sleep cycle; however, it is responsible for some other physical, mental and behavioural changes which occur in any 24-hour period.
At night, when there is darkness, your body produces its highest levels of melatonin, and when your body starts to be exposed to light in the daytime the amount of melatonin produced decreases. Retinas in your eyes receives information on light & dark which then leads to the appropriate amount of melatonin release. This would explain why bright lit screens can have a negative effect on your sleep cycle.
Melatonin also interacts with certain female hormones and can help to regulate menstrual cycles.
From late teens through to age 40, Melatonin levels remain stable, however as we age past 40 melatonin production decreases.
Melatonin can be produced synthetically and can be prescribed to those individuals who do not produce enough naturally, usually this is for short term use.
The quantity and quality of sleep are important factors for our health, the right levels of sleep can improve mood, improve heart health, support healthy growth and development, help regulate hormones which control hunger, support your immune system.
When we don’t get enough sleep, in the short term you may notice a change in mood, have trouble focusing, learning or processing information, experience fatigue or feel lethargic during the day, you may feel hungrier for high fat and high sugar foods. Research has also shown when we aren’t getting good quality regular sleep, we are more likely to become ill after being exposed to a virus and take longer to recover. Long-term lack of sleep can increase your risk of obesity, cardiovascular disease and diabetes.
There are steps we can take to improve our sleep:
Create a restful environment.
Create a sleep schedule (going to bed/sleep and waking up at the same time each night/day).
Reduce or avoid your stimulants in the evenings such as caffeine, ni****ne and alcohol.
Reduce screen time as your sleep time approaches or place your devices on low blue light or night time mode.
Eat foods rich in melatonin.
Take daily exercise.
