What is it about?

We know that vitamin D can help to prevent asthma attacks. Most of our vitamin D comes from exposure to sunlight. We used available data from the Met Office and the Hospital Episodes Statistics databases to see if sunnier regions had fewer asthma admissions.

Why is it important?

This ecological study demonstrates that at a population level, sunnier regions in the East and South East of England have fewer asthma admissions. For every 100 hours of sunshine per year there is a 10% decrease in hospital admissions for asthma in children.


The statistical association between hours of sunshine per year and hospital admissions for asthma was very strong. This adds weight to the evidence that vitamin D might be a useful treatment to reduce asthma attacks in children. It also suggests that the simple public health message of 'get out more and play in the sunshine' is likely to be beneficial to children with asthma.
