Sunshine on the skin helps to generate vitamin D

A study of 3,000 people by Finnish researchers has discovered people with the lowest levels of the vitamin, which is generated in the skin by sunshine, had a three-fold higher risk of developing Parkinson’s.

Experts say this could be because Vitamin D helps to protect the nerve cells gradually lost by people with the disease.

The charity Parkinson’s UK has said more research is needed.

Parkinson’s disease affects several parts of the brain, leading to symptoms such as tremor, stiffness and slow movements.

Most vitamin D is made by the body when the skin is exposed to sunlight, though some comes from foods like oily fish, milk or cereals.

As people age, their skin becomes less able to produce vitamin D. Research is now showing that vitamin D helps to regulate the immune system, as well as helping to develop the nervous system.

Dr Kieran Breen, director of research at Parkinson’s UK, said, ‘The study provides further clues about the potential environmental factors that may influence or protect against the progression of Parkinson’s. A balanced healthy diet should provide the recommended levels of vitamin D. Further research is required to find out whether taking a dietary supplement, or increased exposure to sunlight, may have an effect on Parkinson’s, and at what stage these would be most beneficial.’
