How to rehydrate after the sauna, hot workouts and hot weather.
About this topic
Sauna & heat
Heat makes you sweat, and sweat means losing both fluid and electrolytes. Whether it's a sauna session, a hot yoga class, a cold plunge routine or a warm day, it pays to plan your hydration around it.
Our sauna and heat guides cover sauna benefits, steam sauna and steam room benefits, infrared sauna benefits and whether to use the sauna before or after a workout, with rehydration after the heat running through every piece. Drinking water before you go in and replacing fluid and electrolytes afterwards are good habits to build.
Vidrate sachets make it easy to add electrolytes to your water bottle so you're ready when you come out.
New articles are on the way

Rehydrate after the heat
FAQs
Sauna & heat FAQs
Should I drink water before a sauna?
Yes. Start hydrated by drinking a glass of water beforehand, and take water with you if you plan a longer session.
How do I rehydrate after a sauna?
Drink steadily afterwards rather than all at once. Adding electrolytes helps replace the salts you lose through sweat.
Should I use the sauna before or after a workout?
Many people prefer the sauna after a workout. Either way, both cause sweating, so rehydrate well in between.
Does a sauna help you lose weight?
Any weight you lose in a sauna is mostly water from sweating, and it returns as you rehydrate, which you should do straight after.
Do electrolytes help in hot weather?
When you sweat more than usual, electrolytes can help you replace the salts you lose along with fluid.
