Sunlight has many positive effects on the body:
It increases our vitality and well‐being, promotes circulation and metabolic processes and activates vitamin D production. But we only need a small dose.
The body is able to produce its own protective mechanisms to help against the negative effects of UV radiation – pigmentation, thickening of the external layers of skin, producing antioxidants and the formulation of UV filtering substances such as urocanic acid. But skin needs time and low dosages of UV to be able to protect itself and benefits from additional protection. Read more in how sun affects skin.
Over exposure to UV rays is one of the main causes of premature ageing of the skin and can lead to pathological changes of the skin – in the worst cases to skin cancer. The application of a cream or lotion with added Sun Protection Factor (SPF) is highly recommended to protect the body when it is exposed to UV rays.
