Why is sunshine so important to humans?

Sunshine is important to humans for several reasons: 

  • Vitamin D synthesis: Sunlight is a crucial source of vitamin D, which plays a vital role in the body's absorption of calcium and phosphorus. These minerals are essential for maintaining healthy bones and teeth. When sunlight hits the skin, it triggers a chemical reaction that produces vitamin D. Therefore, regular exposure to sunlight helps prevent vitamin D deficiency.

  • Mood enhancement: How doesn’t one want to feel happier?! Everyone says we are happier when the sun shines but is that true?

 Yes. Sunlight has a positive impact on mood and emotional well-being. 

Exposure to sunlight stimulates the release of serotonin, a neurotransmitter that regulates mood. Increased serotonin levels are associated with improved mood, reduced anxiety, and increased feelings of happiness.

  • Circadian rhythm regulation: Sunlight helps regulate the body's internal clock, known as the circadian rhythm. The circadian rhythm governs various body processes, including sleep-wake cycles, hormone production, and metabolism. Exposure to natural light during the day helps synchronize the circadian rhythm, promoting better sleep at night and overall optimal functioning of the body.

  • Production of melatonin: Sunlight exposure during the day suppresses the production of melatonin, a hormone that regulates sleep. When sunlight decreases in the evening, melatonin production increases, signaling to the body that it's time to sleep. Adequate exposure to natural light during the day helps maintain a healthy balance of melatonin production and supports a regular sleep-wake cycle.

So get outside every day! Even sitting at your front door can help.

  • Skin health: Sunlight has beneficial effects on the skin. Moderate sun exposure can help treat certain skin conditions like psoriasis, acne, and eczema. Additionally, sunlight stimulates the production of vitamin D in the skin, which promotes overall skin health.

But as with all good things they have side-effects!

It's important to note that while sunlight provides these benefits, excessive exposure to ultraviolet (UV) radiation can be harmful. It's crucial to practice safe sun habits, such as wearing sunscreen, sporting a hat, and seeking shade during peak sun hours, to minimize the risk of sunburn and skin damage.
