You may have heard the term "circadian rhythms" and not known exactly what it refers to. Its definition includes any kind of physical, mental or behavioural change that occurs as a result of the light-dark transition. An example of this is staying awake during the day and sleeping at night. But how is melatonin related to this process? This hormone produced by the pineal gland is responsible for telling the body when it is time to go to sleep and when it is time to wake up. An imbalance in the production of this hormone (changes in work shifts, jet lag or mild insomnia) can lead to disturbances in the sleep-wake cycle.
Melatonin supplements help treat these sleep disorders and help provide some relief for mild insomnia. As well as helping to regulate our biological clock, this hormone also acts as an antioxidant that helps to fight free radicals and boost the immune system, reviving our natural defences.
To regulate melatonin levels, it is also essential to introduce a proper sleep routine and habits. For example, avoiding having a late dinner, establishing regular schedules, avoiding caffeine at least 6 hours before going to bed and avoiding using electronic devices at night. If mild insomnia persists, other symptoms appear or if you are taking some kind of medication, it is advisable to consult a healthcare professional.
