I’m one who doesn’t drink enough water. I do drink a ton of coffee and Gatorade when I’m out working in the heat in the summer. This weekend I built a trough for me to fill with protein pellets for the herd of deer I hunt. Went from being able to fill 200# to now 400# at a time. Then put up a deer stand in a new field. All this with a 105-110 heat index. I sweated like crazy but no lightheadedness or cramping thankfully.
Unless you are on a low salt diet, be sure to take some extra to avoid the cramps...............
People who work outdoors need to be sensitive to catching if their body is starting to accumulate heat.
Working, sweating, drinking fluids, skin evaporation, sweating, feeling the cooling if one takes a break or steps in the shade are all the normal parts of working outdoors, but if they notice that their body is starting to build-up heat, that it is accumulating heat, then they need to break-off the work and discontinue until things totally normalize and their system is reset, take a very long break in the house or the vehicle, or in the tub if things are bad.
