  • Drink Different Teas: Start consuming different flavored teas. Opt for the unsweetened kind. Fruit iced teas are great for a summer day whereas a steaming cup of hot peppermint tea is great for winters and will keep you cozy throughout the night.
  • Pay Attention to Snacks: Snacks such as chips, pretzels, and crackers are all low on water content. Switch to healthier food options, such as frozen yogurt, healthy smoothies along with fruits and vegetables.

If you’re thirsty, this is a sign that you need more water. Another great way to determine your fluid status is by inspecting urine color. Light yellow means you are getting enough water while a darker shade indicates you probably need a little more. Taking constant sips will ensure you stay hydrated throughout the day.
