Sunlight Exposure Boosts Immune Function, New Study Reveals
Scientists discovered that exposure to sunlight can boost the immune system.
They studied immune cells in zebrafish, which are similar to humans, and found that these cells work better in daylight.
The cells have internal clocks that respond to light, helping them fight infections.
People with disrupted sleep schedules, like shift workers, might have weaker immune systems.
Experts suggest getting sunlight, especially in the morning, to help keep the immune system strong.
This could lead to new light-based treatments to improve how medicines work.
Sunlight could be a simple way to help our bodies fight off germs.
A recent study shows daylight exposure can boost the immune system's ability to fight infections.
Researchers used zebrafish to study how daylight affects neutrophils, a type of white blood cell.
Neutrophils have internal clocks that respond to daylight, making them more effective during daytime.
Disrupted circadian rhythms may impair immune function.
Experts suggest daily sunlight exposure, especially in the morning, to maintain immune function.
- Who
- Researchers at the University of Auckland studied the impact of daylight on immune cells.
- What
