Yoga and Exercise for Dehydration

Yoga and exercise interact with dehydration mostly at one point: sweat. The practices themselves are fine and healthy - the question is managing fluids around them, especially in Indian summers.

Exercise and sweat: the real connection

• An hour of hard exercise can lose a litre or more of sweat - several litres in summer outdoor sport
• Before: drink 1-2 glasses in the two hours before a workout
• During: sip every 15-20 minutes for sessions over an hour
• After: replace what you sweated out - for long or very sweaty sessions, include salts (ORS, salted nimbu-pani, electrolyte drink)
• Weighing yourself before and after a long session shows exactly what you lost: replace about 1.5 times that

Hot-weather rules for the active

• Shift outdoor runs, sports and heavy workouts to early morning or evening in summer
• Hot yoga / heated studios: real dehydration setups - hydrate before and after, and skip them entirely in peak summer if you are not acclimatised
• Stop signals during exercise: dizziness, chills, headache, cramps, confusion - rest, shade, fluids
• Never "train through" heat illness symptoms

Yoga itself

• Ordinary asana and pranayama practice is not a dehydration risk - keep a bottle nearby in summer and that is mostly it
• During recovery from dehydration: gentle practice only for a day or two - the body is restoring salts and fluids, and strenuous flows can wait
• Breathing practices (sheetali, the traditional "cooling breath") are a pleasant traditional complement in hot months - comfort, not treatment

The myth to drop

• You cannot "detox" by sweating more - heavy sweating without replacement is just dehydration, whatever the marketing says

One-line summary

Exercise is healthy; dehydration is the tax on unmanaged sweat - drink before, sip during, replace with salts after, shift workouts out of the midday summer sun, and treat dizziness and cramps on the field as stop signals, not character tests.
