Water Intake for Hiking: Hydration Guide

Outdoor activity in varying temperatures demands careful hydration planning. Carry at least 0.5 liters per hour of moderate hiking.

      Quick Rule: Add 12 ounces (350ml) of water for every 30 minutes of hiking. Use WaterMinder to set pre-workout and post-workout hydration reminders.
    

Hydration Guidelines for Hiking

Timing	Amount	Purpose
2 hours before	17-20 oz (500-600ml)	Pre-hydrate muscles and joints
15 min before	8 oz (240ml)	Top off hydration levels
Every 15-20 min during	4-8 oz (120-240ml)	Replace ongoing sweat losses
After activity	16-24 oz per lb lost (500-750ml per 0.5kg)	Full rehydration and recovery

Signs You Need More Water During Hiking

Thirst (already 1-2% dehydrated)
Decreased performance or endurance
Muscle cramps or tightness
Dizziness or lightheadedness
Dark yellow urine before or after
Headache during or after exercise

Electrolyte Considerations

For hiking sessions under 60 minutes, plain water is usually sufficient. For longer or more intense sessions, consider adding electrolytes to replace sodium and potassium lost in sweat. WaterMinder lets you log electrolyte drinks separately to track both water and electrolyte intake.

A simple post-hiking rehydration strategy: weigh yourself before and after exercise. For every pound lost, drink 16-24 ounces of water. This ensures complete rehydration for optimal recovery.
