Overview

• The Met Office has forecast temperatures above 30C across much of the UK through the weekend, driving demand for home cooling solutions.
• Filling a hot water bottle three-quarters full with cold water and chilling it in a fridge or freezer can cool sheets and help users lower their body temperature at night.
• Freezing bottles for more than about 20 minutes risks weakening the rubber, which may lead to splits or leaks when they are later used with hot water.
• Appliances specialists advise keeping separate bottles for cold-water cooling and hot-water warming to avoid material degradation.
• Additional cooling hacks include placing a frozen bowl of water in front of a fan, shutting curtains during the day and running wrists under cold tap water to cool down quickly.
