Hey everyone I wanted to post here to see if I could get some feedback regarding heat and headaches. Ever since I was young kid 8 or 9 and played sports in the heat I would get headaches. The headaches were so bad in freshmen year of football I would have to come home and lay down with a fan on me, the lights off, and I couldn't eat so some time after practice. I don't workout and am not in the heat as much as a was back then but if I get to much heat/sun I will still get varying intensities of headaches. Obviously heat is at play but I am curious why it is causing headaches and if there are any other possible physiological things going on that can help prevent them. While if I do a hot sauna for too long I will get a headache, I have noticed in the past few years that I get slight headaches even if I am out in the sun to long or get too much sun. This can be a pretty short amount of time 15-20 minutes and I can feel a headache coming on and often times I don't feel like I am hot or over heating. Any feedback would be appreciated. Thanks
