Hot workouts

Hot yoga hydration guide

Hot yoga can create meaningful sweat loss in a short window. Hydrate before class, sip after, replace salt when sweat is heavy, and stop if dizziness or confusion appears.

Start before class

Arriving dehydrated makes a hot class harder. Drink normally earlier in the day and avoid using class as a reason to chug right before the mat.

A sweat-rate check after a similar class is the best way to learn your personal replacement need.

After class

Replace fluid gradually over the next few hours. If clothes are salt-stained or you feel wiped out, include food or electrolytes.

Heat tolerance varies. Nausea, confusion, fainting, chest symptoms, or severe headache need prompt attention.

Frequently asked

How much water should I drink after hot yoga?

Use body weight change if possible: each 1 kg lost is roughly 1 litre of fluid to replace gradually, plus normal meals.

Do I need electrolytes for hot yoga?

For light sweat, normal meals may be enough. For heavy, salty, repeated, or long hot classes, electrolytes can be useful.
