This is critical! Travelers to the tropics or a climate, like the Southwest United States, are prone to dehydration and heat related conditions.
The tropics and humid environments
It takes a while for our bodies to adjust to the heat, time we may not have during the challenge. You will sweat a lot and may lose a lot of salt. The amount of water to drink depends on the environment, exertion level, and the person. We will provide this water, with snacks to replenish salt and other nutrients. This does not include tea, coffee or alcoholic beverages, which can contribute to dehydration.
The arid environments like the US Southwest
Perspiration may not be as obvious due to the dry air. You are still losing water and salt, even if you are not sweating a lot. Follow the recommendations of your guide, listen to your body, and don’t go by the sweat (or lack thereof) on your shirt.
The hydration urine test?
If your urine is light yellow or almost clear, you are fine. If it is dark yellow, you are not drinking enough. And darker, we hope you never see; that’s a problem.
