A recent study by British scientists found that women who often bathe in sunlight are physically younger and more likely to slow down the aging process than women of the same age who rarely receive sunlight.

The study found that women who received more sunlight had longer telomeres, which are the caps at the end of chromosomes that protect them from damage. Telomeres shorten with age, and when they become too short, cells can no longer divide and die.

Sunlight helps the body synthesize vitamin D, which is essential for bone health and immune function. Vitamin D also plays a role in telomere length.
