Understanding this natural biological oscillation is essential to … Read more

Why Do I Feel Physically Exhausted and Sleepy When It Is Overcast Outside?

1. Introduction Feeling physically exhausted and inexplicably sleepy on an overcast day is a direct physiological response to the lack of bright, natural sunlight, which disrupts the body’s circadian rhythm and alters hormone production.
