I am having a wickid headache right now, and don't get them but once of twice a year. Could it have to do with the fact that I spent about 7 hours today in the sun? If so, how does being in the sun cause headaches?
Headache after being out in the sun for extended periods of time

yes, drink water while your out there and you wont get those headaches.
when you sweat, you are dehydrating yourself dude.

Your brain is telling you that you need water. It won't be long before you are a heat casualty, and worst case, suffer from a heat stroke. Once you become a heat cat, your symptoms get worse, only quicker next time, and it's for life. Once a heat cat, always a heat cat. "Drink wahterrrr...beat the heat drill sergeant, beat the heat!"

Heat stroke. Drink several glasses of water and take a cool shower. Some aspirin or tylenol wouldn't hurt either.
Yeah, I get killer headaches if I'm out in the sun for extend periods of time without a hat or something.

as others have stated, dehyrdration (native arizonan) so you need water and gatorade. and lots of it.
when friends and i used to go hiking/shooting in the desert when it was ~110+F we would each bring atleast 1gal each and 1 of the large 64oz gatorade bottles. atleast in a "dry heat" once your clothes get soaked with sweat they act as a cooler, but in PA with all that humidity i don't know how well that works.
just drink a ton of water/gatorade and not beer.

yes, i get headaches all the time but i find them worse when i'm in the sun. even when wearing a hat, the heat can penetrate and cause the headaches as well. drinking water helps, but it may not necessarily prevent the headache altogether.

You get headaches when you get dehydrated.. which is the same thing that happens after getting drunk and getting a hangover the next morning.
If you want the specifics WHY this happens, it's because of this.
When you start to get dehydrated, your blood thickens and your body starts losing water from every where to try to keep your blood consistency thin enough to travel in your body. So you start losing water from various organs after awhile so your blood doesn't get too thick. The brain is FULL of water and blood. Only other body part with more is the heart water/blood per square inch.
So, when you get dehydrated, your brain literally shrinks. This shrinking causes headaches, and depending on your genetics, even hemoragging as your brain pulls away from the skull.
Ask anyone that's ever had a hangover if they have a headache. The reason is the same and different. When you drink alcohol, your body replaces the water it's using with the fresh intake of alcohol. The more you drink, the more it replaces and the more you pee out the "real water" your body needs. By the time morning comes around, your liver has finally filtered out and chemically processed the alcohol in your system into something else your body can't use as lubrication like water. Now, you are dehydrated because when the alcohol replaced all the water your body would use a lubrication when you pissed it out, chances are you didn't drink water again before passing out. Now, with all the alcohol processed, you can have severe dehydration which will cause headaches in the manner I described above.
NOW, if you are getting headaches after being in the sun for only moments, which wouldn't cause dehydration, then you have a photosensitivity to bright lights. Your eyes get hurt from the brightness of sunlight and due to close wiring of the optic nerve in some people to nerves in the brain, that pain sensation is passed along and felt in the brain as a headache. Note, not everyone who is really photosensitive to light will get headaches either, it just depends on genetics and how close your nerves for your eyes are wired to you brain. For me, mine are closer to my nose so anytime I get hit with bright light I go into sneezing fits until my eyes adjust. Which happens to other people as well.
Usually people with lighter eye color are prone to photosensitivity problems. I have bright green eyes so I can be. My dad has blue eyes so light they are almost white when he's indoors. When he steps outside, his eyes go bloodshot in an instant.

I always get headaches if I stay out too long in the sun. But they ALWAYS go away once I have a nap.
Thanks for all the info, I probably didn't get enough fluids. I had like a 12 ounce bottle of water and 2 cans of soda or so. Thanks for all the replies.

defiantely not enough, especially with the soda, stay away from it or drink a lot more water than normal to compensate for the soda. a few years ago i was in a wedding in the wine country near san francisco, it was memorial day weekend and and outdoor daytime wedding and i was in a 3piece (wool) suite (hugo boss, so comfortable
), i drank so much water and no alcohol, needless to say i was one of the only people to not feel like sh!t later that day and the next day, and this was a 12+hour event as it was my and my wife's best friend.
