Why do I always feel sleepy after swimming in the beach?

Question

Is it the heat and me being tired or is there something in seawater?

Answer 1

For me, I have noticed that being out in the sun for a few hours makes me sleepy.  This is compounded with the heat at the beach (heat makes you sleepy, that's why in most countries they (at least used to) take a nap in the middle (ie hottest part) of the day.  Also, you have the physical exertion of swimming in the ocean, which will also make you physically tired (although might wake you up if the water is cold!).  It shouldn't have anything to do with the saltwater though...

Answer 2

it's actually the sun, which almost literally drains the energy out of you.

Answer 3

samethin happens to me . i guess its because of allergy or its the salty water

Answer 4

no, it happens to me too after I use too much coke. I stay up and then when I come out of the water I smoke a blunt and just want to sleep. Or maybe just too much beer? Actually I know fat girls have this problem alot. See if dieting  helps, if not just go with it and enjoy your nap.
