The sun has always been a fundamental source of life and energy on our planet. Throughout history, it has been revered by various cultures for its many health and well-being benefits. Today, science has supported the importance of sunlight exposure on people's physical and mental health. In this article we will delve into the beneficial effects that increasing hours of sunlight has on human well-being.

One of the most notable effects of increased exposure to sunlight is its impact on mood. Sunlight stimulates the production of serotonin in the brain, a neurotransmitter that is directly related to mood regulation and feelings of happiness. When we are exposed to sunlight, our body increases the production of serotonin, which can help improve our mood and reduce symptoms of depression and anxiety.
In addition, sunlight also promotes the release of endorphins, commonly known as the "happiness hormones". These chemicals act as natural pain relievers and generate a feeling of well-being and euphoria in our body. Therefore, spending more time outdoors in sunlight can have a positive effect on our overall mood, helping us feel more optimistic and energetic.

This disorder, also known as seasonal affective disorder (SAD), is characterized by symptoms of depression that arise and persist during certain seasons of the year, usually winter.
Seasonal depression is related to a decrease in exposure to sunlight, which affects the production of serotonin and melatonin in the body.

When we expose ourselves to sunlight during the day, especially in the early morning hours, we help synchronize our circadian rhythm, which can improve the quality and duration of sleep during the night.
The Sunlight also helps regulate the production of melatonin, the hormone responsible for inducing sleep. Exposure to natural light during the day suppresses melatonin production, which keeps us alert and active. As the sun sets, the decrease in sunlight triggers the release of melatonin, preparing our body for a night's rest. This natural process is essential to maintain a healthy and restful sleep cycle.

Moderate exposure to sunlight is one of the main sources of vitamin D for humans, so ensuring adequate sun exposure can strengthen the immune system and reduce the risk of diseases related to deficiency of this vitamin.
Blood pressure regulation
In addition to vitamin D synthesis, sunlight can also have a positive impact on blood pressure regulation. Studies have shown that regular exposure to sunlight can help reduce blood pressure, a major risk factor for cardiovascular diseases such as hypertension. Sunlight stimulates the production of nitric oxide in the skin, a substance that dilates blood vessels and improves blood flow, which helps lower blood pressure.
In addition, exposure to sunlight It may also have beneficial effects on the skin, promoting wound healing, reducing inflammation, and improving certain dermatological conditions such as acne and psoriasis. Sunlight acts as a natural disinfectant due to its antibacterial and antifungal properties, which can benefit overall skin health.
Recommendations for healthy exposure
