One of the common problems in the absence of sun is depression. The fact is that sunlight stimulates the production of serotonin – the hormone of joy and pleasure. Light also regulates our circadian rhythm, our internal clock. When exposed to sunlight, the body begins to produce less melatonin, but in the dark the opposite is true. Anxiety, insomnia, and a feeling of chronic fatigue may occur due to lack of sunlight.
The memory and concentration of a person who does not have regular contact with the sun also deteriorates. This is especially true for the elderly.
Vitamin D production decreases with lack of sunlight. It is important for bones, immunity, heart and metabolism. Due to the deficiency of this vitamin, muscles weaken, bones become brittle, the person often catches colds and infections, and the risk of serious cardiovascular diseases increases.
Small doses of UV radiation help wounds heal faster, destroy fungi and bacteria, and reduce inflammation. With prolonged lack of sun, the skin ages faster, becomes more susceptible to infections, and looks unhealthy and dull.
Completely avoiding sunlight makes vision less sharp, increases the risk of developing myopia, and can cause retinal deterioration, especially in the elderly.
Lack of sun is also linked to dysregulation of blood sugar and lipids. As a result, the body absorbs glucose worse, fat accumulation increases, the risk of developing diabetes and lipid metabolism disorders increases.
