Melatonin is a hormone produced by the pineal gland of the human body and is mostly associated with maintaining the body’s sleep schedule. In other words, it triggers sleep. Hence, a healthy functioning human body produces strong level of melatonin at night which diminishes at dawn.
However, often due to conditions like anxiety, depression and gastric problems, the body doesn’t function effectively. This leads to insomnia which promotes unhealthy sleeping pattern and results in a reduction of melatonin production.
However, sometimes, there are other underlying factors too which affect melatonin production.
