Introduction
A few simple food choices can support your body’s natural cooling system. When temperatures rise, your body works hard to keep cool. Sweating helps you stay safe — but it also increases your need for fluids and electrolytes. Choosing the right foods can support hydration, digestion, and comfort during the heat. In this guide, you’ll discover the top 12 cooling foods and practical ways to reduce body heat naturally. You’ll also learn how to stay safe when heat becomes overwhelming and when to call it an emergency.
Why does body heat rise, and how does food help
Your dietary choices can make temperature regulation easier for your body.
- Your skin and sweat glands help release heat; when humidity is high, cooling becomes harder.
- Dehydration reduces sweating and makes you feel hotter.
- High-water foods offer extra hydration and are easier to digest than heavy meals.
- Eating smaller, more frequent meals helps reduce the heat produced during digestion.

Smart ways to build a summer diet that keeps you cool
A few everyday habits can boost hydration and comfort.
Hydrate on a schedule
Don’t wait until you feel thirsty — that’s already a sign of dehydration.
- Carry a reusable bottle
- Sip more in heatwaves
- Add fruit slices for flavour
Include electrolytes when needed
You may need more minerals if sweating heavily.

- Speak to a clinician if you have heart/kidney conditions
Choose lighter, cooler meals
Help digestion work with you, not against you.
- Salads, chilled soups, fruit plates
- Smaller meals more often
Be mindful of caffeine and alcohol
- Can increase urine output → dehydration
- Replace each drink with water
- Avoid during peak heat hours
Spicy foods — helpful or not?
It depends on humidity.
- Dry heat → sweating cools you efficiently
- Humid heat → sweat doesn’t evaporate well and may feel uncomfortable
Keep food safe in the heat
- Refrigerate promptly
- Use coolers outdoors
- Avoid leaving food out more than 1–2 hours

Refreshing flavours, minimal effort.
