Light – The Benefits
Humans require light of a specific intensity and colour range to regulate their internal biological clock. Without it -our daily, monthly and annual rhythms become disrupted.
Light is absorbed by our skin and most potently through our eyes. Light enters the eye and via the retina, regulates the body’s ‘light meter’, the pineal gland. These photocurrents influence internal endocrine glands that control biological functions such as sleep and wakefulness, hormone production, body temperature, breathing, digestion, sexual functions, moods, the immune system and the ageing process.
Light stimulates retinal and optic nerve function, improving vision and eye health. It also triggers the production of Vitamin D, which plays a key role in the absorption of calcium from foods and in consequence the healthy development of bones and teeth.
