Home remedies for dehydration: ORS, coconut water, nimbu-shikanji and buttermilk
Heat, loose motions, vomiting, fever or simply not drinking enough can leave you dehydrated — thirsty, tired, dizzy, with dark urine. These home remedies for dehydration replace both water and salts: ORS, a homemade salt-sugar solution, coconut water, nimbu-shikanji, buttermilk and water-rich fruits.

Important: this remedy is only a supportive home measure. Keep taking any medicine your doctor has prescribed, monitor your readings, and consult your doctor before adding anything new.
Understanding dehydration
The body loses water and salts through sweat, urine, stools and vomit. When losses aren't replaced, blood volume drops, causing thirst, dry mouth, headache, weakness, dizziness and dark, scanty urine. Children and older adults can become dehydrated quickly.
Indian summers have a rich tradition of rehydrating drinks — nimbu pani, chaas, aam panna and nariyal pani.
Ingredients
- ORS sachets, or 1 litre boiled-cooled water + 6 level teaspoons sugar + half a teaspoon salt

How to prepare
- Mix ORS exactly as directed, or prepare the homemade solution with exact measures.

- Alternate with coconut water, shikanji and buttermilk.
- Eat water-rich fruits like watermelon, cucumber and oranges.
Helpful habits
- Keep a water bottle with you in hot weather.

Precautions

- Seek urgent care for confusion, fainting, very little or no urine for 8 hours, sunken eyes, rapid heartbeat, or inability to keep fluids down.
- Babies, young children, older adults and people with kidney or heart disease need medical advice early.
