Sleep expert Nerina Ramlakhan says "there needs to be a fractional temperature difference between our body and our brain - a warm body and a cool head."

"When the outdoor temperature rises this becomes more difficult but there are plenty of things you can do to beat the heat," a website quoted Nerina as saying.

Here are some tips:

* Keep a plant mister containing water by your bed to spray on your face during the night.

* Stop your bedroom overheating during the day by keeping curtains and blinds closed.

* Wash your feet with cold water before getting into bed, and/or run your wrists under cold water.

* Place a wet flannel in the fridge for an hour or so before getting into bed and lay it on your forehead to help you drift off to sleep.

* Sleep in cool wet socks or even a damp T-shirt.

* Use light bed sheets.

* Finally, and most importantly stay well hydrated during the day and don't fret too much if you can't sleep. Use the time to rest and think positive thoughts, then you will be extra productive the day after.
