This tip comes courtesy of Natalie in our Facebook group, who suggested taking a wet towel to bed. In her own words, having tested it out in a hotel, it was "bliss". Lizzie also suggests running cold water over a sheet, wringing it out and laying underneath it at night. It'll help to cool you down, and as it should be dry by the morning, you can quite literally rinse and repeat. You can adapt this tip for use during the daytime, too. Just take an old T-shirt (you won't want to ruin the shape of one you like) and run it under some cold water. Wring it out to get rid of the excess water, and then either drape it over your shoulders or wear it as normal.
