Why does a day at the beach make people tired?!
Question:
Why does a day at the beach make people tired?
I've always found myself really really tired after a day at the beach when all I did was lie around and jump at incoming waves.
Why is that? Is it actually causing fatigue or just correlation with something else?
Answers:
Researchers have found out that vitamin D helps boost levels of serotonin. Sun exposure produces Vitamin D. Serotonin, on the other hand, induces sleep. This may explain why we feel tired like you did after a day at the beach.
