How the lack of natural light affects our health

Our bodies need the vital energy found in natural light to support our immune system and help us to fight physical and psychological disease. With exposure to natural light and fresh air, our bodies feel nourished and our minds alive.

Light affects the pituitary and pineal glands, both master glands of our endocrine system. These control the release of hormones into the body. If our hormones are not balanced, we can suffer from hormone-related problems such as mood swings, irrational behaviour and panic attacks.


Sunlight Makes us Fell Better


Exposure to sunlight not only makes us feel happier, less stressed it helps to regulate hormones and aids in a good night’s sleep. Natural light travelling to the brain also releases endorphins into our bloodstream that give us the feel-good factor.

We must be exposed to a minimum of thirty minutes each day of natural light, without wearing sunglasses or sitting behind a windscreen of a car. Exposure to natural light and fresh air daily helps to regulate our circadian rhythm, which governs our biological clock.
