How does the body prevent itself from overheating in exercise?

How does the body prevent itself from overheating in exercise?

Sweating: At least two mechanisms. The body first reacts by dilating (enlarging the diameter) of the vessels near the skin surface, thus allowing for more surface area heat exchange to occur. Sweating is additive to this process, cooling the skin by evaporation. Together, these processes help to prevent overheating. Normally, we sweat as much as a liter throughout the entire day. ...Read more

I find that whenever I am close to or on my menstrual cycle I get hot and overheated very easily. Like my body temp gets extremely sensitive to heat when I could normally tolerate it for longer?

I find that whenever I am close to or on my menstrual cycle I get hot and overheated very easily. Like my body temp gets extremely sensitive to heat when I could normally tolerate it for longer?

Just a theory....: During the second half of your menstrual cycle, your hormone levels are at their highest. You might be retaining fluid during this time. Hormone levels drop in the premenstrual period and the kidneys remove that excess fluid. If you're relatively dehydrated, you might be more susceptible to heat stress. Perhaps drinking extra fluids will help you tolerate heat better. ...Read more

Just do an HIV test: Some people are known to get leg itching and rashes from running (cause is unknown). If it is from histamine release, one can try taking Claritin (loratadine) or Zyrtec, 1/2 hour before running. If it is from the heat, try running at sunrise. If it is from blocked sweat glands, try a sauna 3 times a week. Maybe one can make a dermatologist appointment, and then run to the clinic to show a fresh itchy rash. ...Read more

I've started having night sweats, with an onset of one year ago. I wake up to drenched sheets but I'm not overheated. I don't sweat during the day.

I've started having night sweats, with an onset of one year ago. I wake up to drenched sheets but I'm not overheated. I don't sweat during the day.

Fever?: Assuming the room is not overly warm, and not using unnecessarily heavy covers, this is something to see a doctor about. True night sweats occur because of fever that drops during the night. See a doctor, and for a week before your appointment, take your temperature (and write down the results) 3 times a day: when you awake in the morning, 4-6 pm, and at bedtime. Also record the nights you sweat. ...Read more

This is a common occurrence in TB and in some lymphomas. See a doctor. ...Read more
