Why natural light is good for your mental health

Mental Health & Wellbeing

Sunlight can play a crucial role in promoting physical and mental well-being, impacting our mood, sleep, energy levels, and overall quality of life. Incorporating regular exposure to natural light into our daily routines can contribute to a healthier and more balanced lifestyle.

It can be tricky in the cooler months to get out of the house for even a limited amount of sunlight (weather permitting) but when there is an opportunity we recommend you grab it with both hands.

In this blog, we discover some ways in which sunlight can positively impact our physical and mental health.

Vitamin D synthesis

Sunlight is a natural source of vitamin D, a vital nutrient that supports various bodily functions. When sunlight interacts with our skin, it triggers the production of vitamin D, which is crucial for bone health, immune function, and mood regulation. 

Sufficient vitamin D levels are associated with improved mental well-being.

Mood enhancement

Sunlight exposure triggers the release of serotonin, often referred to as the "feel-good" hormone. Serotonin helps regulate mood, sleep, and appetite, and low levels are linked to conditions such as depression and seasonal affective disorder (SAD). Sunlight exposure can boost serotonin levels and improve overall mood and well-being.

Circadian rhythm regulation (big word - Circ-arrrr-dian we think)

Exposure to natural light helps regulate our internal body clock, known as the circadian rhythm. Sunlight exposure during the day helps synchronise our sleep-wake cycle, promoting better sleep quality at night. 

A well-regulated circadian rhythm contributes to improved energy levels, mood stability, and overall well-being.

Increased energy and productivity

Sunlight has an energising effect on the body. Exposure to natural light can help combat fatigue, increase alertness, and improve cognitive performance and it can enhance productivity and concentration, leading to a greater sense of accomplishment and overall well-being.

Improved sleep quality

Sunlight exposure during the day helps regulate melatonin production, a hormone that plays a crucial role in our sleep-wake cycle. Exposure to natural light in the morning and throughout the day can help maintain a healthy sleep pattern, leading to better sleep quality and overall well-being.

Reduced stress and anxiety

Sunlight has a calming effect on the body and can help reduce stress and anxiety levels. Spending time outdoors and soaking up the sun's rays can promote relaxation, decrease cortisol (stress hormone) levels, and enhance overall emotional well-being. 

Bone health

Sunlight exposure is essential for the synthesis of vitamin D, which is vital for calcium absorption and bone health. Adequate sunlight exposure, along with a balanced diet, supports the development and maintenance of strong and healthy bones.

Balancing sunlight exposure with sun protection measures, such as wearing sunscreen, protective clothing, and sunglasses, can help reap the benefits while minimising potential risks.
