A hot water bottle, typically used for warmth in winter, can be an effective and affordable tool to keep cool during summer heatwaves. According to John Lawless from BestHeating, filling a hot water bottle with cold water or ice and placing it in bed or against pulse points can help lower body temperature quickly.
How It Works
Heat naturally transfers from warmer objects to cooler ones. A cold hot water bottle absorbs heat from your body, dispersing it and making you feel cooler. Unlike fans or air conditioners, which only circulate air, this method directly cools you through conduction.
How to Use a Hot Water Bottle to Stay Cool
Fill a hot water bottle with ice cubes, crushed ice, or chilled water from the fridge. Remove any cover before filling. Place it against pulse points such as the neck, wrists, or ankles for faster cooling. For overnight use, put it at the foot of the bed or near your pillow before sleeping.
If the bottle feels too cold against your skin, wrap it in a towel or pillowcase. Avoid putting the bottle in the freezer for more than 20 minutes, as water expansion can cause leaks or cracks.
Benefits Over Fans and AC
Fans and air conditioners cool by evaporating sweat, but they do not eliminate heat. A cold hot water bottle directly removes heat from your body, providing immediate relief without electricity. This method is also cost-effective and environmentally friendly.
