To stay hydrated is important all around the year, and all through the day. Here are some things you can do to ensure that.
1. Always carry a water bottle wherever you go. Make sure you have water filled in the bottle.
2. Eat fruits, especially juicy, watery ones. Have a lot of cucumber/tomatoes/watermelon, and the likes.
3. Drink fruit juice.
4. Have lemonades- you get your share of boost in immunity, you stay hydrated and it is very tasty.
5. Have buttermilk(chaas/mor), if you like it. It's tasty, easier to have a lot, and basically a lot, lot, lot of water.
Also, have other items that help maintain such hydration, such as radish, strawberries, papaya, spinach, lettuce, curd, and others. Don't forget the magic of tender coconuts! Even having soups with your meals can make it tasty, and also add water content in your body. Avoid foods that have too much salt or sugar in them. A little bit of both helps, but an excess just makes you more thirsty and feel a little dehydrated.
The key is to have a conscious, continuous intake of water and water-based foods. Drink a lot of water before you go to bed, so that you don't wake up feeling dehydrated in the morning- 7 or 8 hours without water is a lot (not to mention some of us sleep way more than that)!
This summer, beat the heat, and stay hydrated!
