Stay Cool From the Inside Out: Foods That Lower Body Heat Naturally

15. Buttermilk: Ancient Cool with a Modern Twist

A time-tested remedy in Indian households, buttermilk is a probiotic-rich drink made from diluted yogurt, often spiced with herbs like cumin or mint. Light, tangy, and easy to digest, it cools the digestive tract while replenishing electrolytes and beneficial bacteria. It’s especially useful after a heavy meal or long day in the sun. Buttermilk helps balance body temperature, soothe the gut, and prevent dehydration—no wonder it's been a summer go-to for centuries. Serve it chilled, seasoned, and sipped slowly. It's humble, effective, and far more refreshing than it looks.

16. Celery: Crunch That Cools on Contact

Celery might seem basic, but it’s one of the most hydrating foods around—made up of about 95% water. Its naturally salty profile replenishes lost sodium, making it a great post-sweat snack. Rich in electrolytes, potassium, and antioxidants, celery helps regulate fluid balance and reduce internal heat. It’s also low in calories and high in fiber, making it a smart option when you want something light yet satisfying. Enjoy it raw with hummus or peanut butter, blend it into a green juice, or chop it into chilled soups for a crisp, cooling crunch that works from the inside out.
