Heat acclimatization occurs when repeated heat exposures are sufficiently stressful to elevate body temperature and provoke perfuse sweating. Resting in the heat, with limited physical activity to that required for existence, results in only partial acclimatization. Physical exercise in the heat is required to achieve optimal heat acclimatization for that exercise intensity in a given hot environment.
Generally, about two weeks of daily heat exposure is needed to induce heat acclimatization. Heat acclimatization requires a minimum daily heat exposure of about two hours (can be broken into two 1-hour exposures) combined with physical exercise that requires cardiovascular endurance, (for example, marching or jogging) rather than strength training (pushups and resistance training) .
The benefits of heat acclimatization will be retained for ~1 week and then decay with about 75 percent lost by ~3 weeks, once heat exposure ends. A day or two of intervening cool weather will not interfere with acclimatization to hot weather
Best results will come from gradually increasing work time in hot conditions over a period of 7 to 14 days, and cooling off and fully rehydrating between shifts.
Typically, acclimatization requires at least two hours of heat exposure per day (which can be broken into two, 1-hour periods).
The body will acclimatize to the level of work demanded of it. Simply being in a hot place is not sufficient. Doing light or brief physical work in the heat will acclimatize you ONLY to light, brief work. More strenuous or longer tasks require more acclimatization.
All these suggestions are excellent, but I cannot emphasize enough how much of a difference it makes to wear only moisture-wicking clothing (undergarments included), as opposed to cotton. Significantly cooler, drier, and more comfortable. (If you opt to wear hats/caps, keep it light and breathable so heat can escape.)
When I first started running, I wore regular cotton clothes because that’s what I already owned. Other runners urged me to buy proper wicking exercise clothes, and when I eventually conceded probably a year later, it literally changed my life! Or at least it made running in the heat not suck quite as badly. Anyway, that’s what I wear now any time I do anything outside in the heat. I sure hope you have a great trip and stay as comfortable as possible!THIS is really good to know! I have all my dry-wick clothes ready to go but I was never sure if they made a difference or not. Guess I'll find out in a couple of weeks!
Don't go!We've got a trip coming up in July and I'd love to hear everyones tips for beating the July heat?
