A review of studies demonstrate the multiple effects exposure to sunshine has on immune health and viral transmission
Key Points
- Vitamin D, produced upon exposure to UVB from sunshine, has demonstrated anti-infective, anti-inflammatory, and immunomodulatory properties, and influences approximately 2000 genes, many of which have to do with immune cell function
- Nitric oxide, released upon exposure to UVA, plays a key role in immunity, cellular function, neurotransmission, and also has antimicrobial and anticancer effects
- Several studies reviewed provide evidence that increased sunlight may not only help reduce the risk of severe viral infections, but it may also be an effective disinfectant for influenza, SARS-CoV-2 and other viruses
Exposure to sunshine can have profound impacts on immune health.
