The production of melatonin is regulated by a part of the brain called the suprachiasmatic nucleus (SCN). The SCN receives signals from the eyes about the presence or absence of light and uses this information to regulate the production of melatonin by the pineal gland. Meaning the presence of light at night will inhibit the production of melatonin as the light entering the eyes will give the body the signal it is daytime — which is generally not a time to rest and repair.

The Pineal Gland and Melatonin

The pineal gland is a tiny, pinecone-shaped gland located in the center of the brain. It is often referred to as the "third eye" because it is the only part of the brain that is not protected by the blood-brain barrier and is therefore sensitive to changes in light and darkness, just like our eyes. The production of melatonin is regulated by the suprachiasmatic nucleus (SCN), a part of the brain that receives signals from the eyes about the presence or absence of light. The SCN uses this information to regulate the production of melatonin by the pineal gland.

6 Ways melatonin supports your health

1. Antioxidant Properties 
   
   Melatonin is a powerful antioxidant that can help to protect cells from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to aging, cancer, and other diseases. Melatonin can help to neutralize free radicals and reduce the risk of disease.
   
   
2. Anti-inflammatory Effects
   
   Melatonin has been shown to have anti-inflammatory effects, which means it can help to reduce inflammation throughout the body. Inflammation is a contributing factor in many chronic diseases, including heart disease, diabetes, and arthritis.
   
   
3. Immune System Support
   
   Melatonin supports the immune system by stimulating the production of immune cells and helping to regulate the immune response. This can help to reduce the risk of infections and other immune-related disorders.
   
   
4. Neuroprotective Effects
   
   Melatonin has been shown to have neuroprotective effects, which means it can help to protect the brain from damage and reduce the risk of neurological disorders such as Alzheimer's disease and Parkinson's disease.
   
   
5. Regulating Metabolism & Healthy Weight
   
   Studies have demonstrated that individuals with low melatonin levels are more likely to be overweight or obese and that improving melatonin levels can help to regulate metabolism and reduce body weight.
   
   
6. Mental Health & Mood
   
   Melatonin has been shown to have a positive impact on mood and mental health. Research has linked low melatonin levels to an increased risk of depression, anxiety, and other mood disorders. Studies have also shown that melatonin supplementation can help to alleviate symptoms of depression and improve overall mood.

The Main Takeaways

Disruptions to the production of melatonin, such as exposure to bright lights at night, can interfere with sleep and have serious negative impacts on overall health. Therefore, it is essential to optimize the production of melatonin by taking the following steps:

• Dim the lights after sunset and avoid exposure to bright lights.
• Turn off screen devices such as TVs and phones
• Wear Ra Optics sunset lenses if you cannot avoid artificial (blue) light at night.

In conclusion, melatonin is a vital hormone that plays a crucial role in regulating our internal clock, promoting restful sleep, and providing a range of health benefits. By optimizing its production, we can keep our bodies healthy and young for years to come.
