Ever felt tired after standing outside for a few minutes? Done nothing but stand outside, or casually lounge around in daylight - and still feel tired? Fatigue after standing in the sun is not just 'being tired after minimal exertion', as refinery29 gave reasons to validate exhaustion after exposure to the sun:
Your body is working hard — even if you aren't.
Your body has to work to keep your core body temperature regulated (through sweat).
You're dehydrated.
A 2012 study published in the Journal of Nutrition found that even mild dehydration can be enough to alter your mood, including making you feeling fatigued.
You're red as a lobster.
In an effort to heal your sunburn, your body will divert fluid to the skin’s surface and away from the rest of the body, says Shari Lipner, MD, PhD, assistant professor of dermatology at Weill Cornell.
Something bigger is off with your body.
If you’re sweating heavily, have a rapid pulse, and feel faint in addition to feeling sleepy, those are all signs that you’re experiencing heat exhaustion, according to the Mayo Clinic.
