The Impact of Sunlight on Cortisol Levels

Cortisol is a steroid hormone that is associated with stress and has a wide range of functions in the body. From controlling the body's blood sugar levels to regulating metabolism, and even reducing inflammation, cortisol plays a crucial role in a number of bodily functions. However, one of the main aspects that can affect cortisol levels in the body is sunlight exposure.

Cortisol Production and Sunshine

Cortisol production in the body follows a diurnal rhythm. It's normally high at dawn, reduces throughout the day, and reaches its lowest point at midnight. This rhythm is largely influenced by sunlight exposure. Morning sunlight in particular appears to help in stimulating the body to produce adequate levels of cortisol. According to a study published in the International Journal of Biometeorology, sunlight exposure in the morning from 6 to 8:30 AM increases cortisol production.

Benefits of Balanced Cortisol Levels

Balanced cortisol levels in the body have numerous benefits. They aid in managing stress levels, control blood sugar levels, reduce inflammation, and can even boost weight loss. Adding morning sunlight exposure to your routine can therefore aid in maintaining optimal cortisol levels and contribute to improved physical health and wellness.

Limitations and Further Research

While sunlight exposure and cortisol production seem to have a strong correlation, more research needs to be conducted to fully grasp their interplay. Individual variations such as age, skin type, and geographical location can also impact the relationship between cortisol production and sunlight exposure.
