Sunlight offers surprise benefit: It energizes infection fighting T cells

Natural sunlight exposure is associated with various health benefits, but latest findings suggest it can also help boost infection-fighting T cells of your immune system. T cells play an important role in the immune system functioning and warding off infection, and now researchers uncovered how sunlight can boost their activity.

    Key Takeaways:

  • Sunlight, through a mechanism separate than vitamin D production, energizes T cells that play a central role in human immunity, researchers have found. The findings suggest how the skin, the body’s largest organ, stays alert to the many microbes that can nest there.
  • Georgetown University Medical Center researchers have found that sunlight, through a mechanism separate than vitamin D production, energizes T cells that play a central role in human immunity.
  • Their findings, published today in Scientific Reports, suggest how the skin, the body’s largest organ, stays alert to the many microbes that can nest there.
