A study led by the University of Surrey has revealed that individuals with severe vitamin D deficiency are 33% more likely to be admitted to hospitals due to respiratory infections. Vitamin D, which is synthesized by the body through sunlight exposure and found in foods like oily fish, red meat, and egg yolks, plays a crucial role in maintaining bone and muscle health.

The research indicates that individuals with vitamin D levels below 15 nmol/L are at a significantly higher risk for conditions such as bronchitis and pneumonia. Abi Bournot, the study's lead author, noted that the antibacterial and antiviral properties of vitamin D are believed to contribute to a lowered risk of respiratory tract infections. She emphasized that the study provides concrete data supporting this theory.
Despite its benefits, many individuals do not reach the government-recommended intake of 10 micrograms of vitamin D per day. The study drew on NHS data from 36,258 participants, revealing that for every 10 nmol/L increase in vitamin D levels, the rate of hospital admissions for respiratory infections decreased by 4%.
