How to Keep Cool During the Summer: Freeze a Hot-Water Bottle
Your hot water bottle is your best friend during the summer, but not in the way that you'd think. Fill your hot-water bottle up with cool water, and stick it in the freezer for a few hours before you want to use it. You can either stick the bottle on your lap while you work or relax, or tuck it in between your bedsheets as you get ready to hit the hay. We love the YUYU (£45) bottles for this because they're super long so will cool down your bed more efficiently.
