Water and salt tablets. Also put a wet towel over your neck to keep you cooler and lose less water through constant sweating.

You don’t have to buy expensive garbage like Gatorade! You can make an electrolyte drink yourself and save money.

• 1 l water
• 0.5 TEAspoons normal salt
• 6 TEAspoons sugar or glucose

Warm everything together while mixing to dissolve the sugar, then allow to cool fully.

You can add some flavor when it has cooled. Lemon, or lime, or artificial flavor if you prefer…

Put it to a bottle, it’s ready to go.

Don’t give this to small kids without diluting, they cannot handle a lot of salt. For kids (under 1 year), adjust with water, rule of thumb it should taste like at most teardrop level saltiness. Over 1 year can drink as-is. If in doubt, give under one-year olds something from the pharmacy to get the salt amount correct.

Edit: typoed spoons, please check

At the risk of giving away a hidden gem, Aquarius and Pocari Sweat are even better than Gatorade in my experience. Get the powder if you can, especially if you’re making a lot at a time.

Liquid IV packets have worked better for me working outdoors doing manual labor than Gatorade, but Gatorade is definitely good too.

I’d suggest Gatorade. Hell, I recently read that Gatorade’s ingredients are almost exactly the same as what hospitals use to help dehydrated people.

Here.

Drink electrolytes (like gatorade) in addition to plenty of water. Do not substitute Gatorade for water. Your body needs electrolytes but only in moderation. Shade will do more for water conservation than you realize. If you stop sweating and you are still hot, stop what you are doing immediately and go drink more water. If you are doing everything right, your piss should be clear or very light in color. If you have dark piss, go drink more water.

I bought a 1 gallon jug recently. I bring it to work every day and it keeps me hydrated for the day. Some of my coworkers only drink one or two bottles of water a day. The workplace has air conditioning, but lacks drinkable water as the tap water in that area is unsafe to drink. The work is also physically demanding, it involves a lot standing, walking, and heavy lifting.

I have an rtic gallon jug that I fill with ice and water everyday. I drink the whole thing during my 10 hour shift. I also drink a Powerade throughout the day. I normally take a sip or two of that and then go for the water.

I try not to sweat

You know those special evaporate cooling towels?

They’re bullshit. Evaporation cooling works, but the sooper speshul microfiber bullshit is no better than a regular thin piece of cloth.
