Irritating noises
Some people find the humming sound of a fan soothing. But for others, it can be a drag. Especially if the fan starts to squeak or rattle, it can imperceptibly reduce the quality of your sleep.

So what can you do during warm nights?
To cool down without a fan, you can try the following tips:

Keep windows and curtains closed during the day to keep the heat out.

Sleep under a cotton or linen duvet; these fabrics breathe better.

Use a hot water bottle filled with cold water or a cooling pillow.

Take a lukewarm shower before going to bed.

Ensure adequate hydration.
