What is Melatonin What is the Right Way to Take Melatonin

Overview Melatonin

Melatonin is a  hormone found in the body naturally. It is a ‘sleep-inducing hormone,’ playing a key role in sleep. It is also shown to help regulate the body’s circadian rhythm towards setting a natural sleep cycle. Melatonin is the secretion of the pineal gland in the brain.

The Role of Melatonin in Improving the Sleep and Wake Cycle

Insomnia, which refers to a complaint of delayed and/or inadequate sleep, is a common disorder resulting in negative health effects. The primary role of melatonin is to regulate the body’s wake-sleep  cycle each day and night. The body’s internal clock tells the brain how and when to regulate the release of melatonin.

Darkness causes our body to produce more melatonin that signals our body to prepare for sleep. Light reduces the production of melatonin and signals your body to prepare for being awake. Some individuals who face difficulty in sleeping have low melatonin levels. It is believed that adding melatonin from supplements may help such people sleep.

Melatonin Supplements

Humans are not the only melatonin producers. Other organisms  capable of secreting melatonin include algae, fungi, insects, and plants among others. Vegetables and fruits also contain melatonin. When the hormone is produced within the body, it is termed endogenous melatonin. When produced artificially, it is exogenous melatonin. These days, it is available in the form of supplements, such as pills, capsules, and liquids.

As melatonin is a naturally occurring hormone, the short-term effects of supplements can help with certain sleep disorders such as:

  • Irregular sleep-wake cycle
  • Delayed sleep disorders
  • Circadian rhythm disorders
  • Jet lag

How to Use Melatonin Correctly?

  • When you find it difficult to fall asleep, maybe due to work stress or long travel, melatonin supplements can help.
  • If you decide to take supplements, ensure not to take a high dose. One to three milligrams of melatonin is advisable.
  • It is best to take it two hours before going to bed. According to sleep experts , the human body naturally produces melatonin two hours before the typical bedtime.
  • Individuals who wish to prevent jet lag should start taking it a few days before leaving for their trip. Time it properly.
  • Watch for side effects if any. Side effects of melatonin supplements are not too severe, but can include nausea, headaches, and dizziness.
