One of the most brilliant yet simple travel hacks for hot climates involves freezing water bottles overnight – a technique that transforms ordinary bottles into all-day cooling systems that can make or break your comfort in scorching destinations.

The Science Behind the Magic:

When you freeze water bottles overnight, you create a dual-purpose travel tool: immediate cooling relief and continuous cold hydration throughout the day. As the ice slowly melts, you have access to ice-cold water for hours, even in extreme heat. The frozen bottles also act as ice packs, cooling everything around them in your bag.
