The UK sweltered through one of the hottest days of the year so far on Monday - with highs of 35C (95F) possible on Tuesday.
That also means a tropical night for many of us, with temperatures not falling below 20C (68F) overnight.
If you're struggling to sleep, here are some top tips for staying cool.

Stay hydrated
It may seem like an obvious one, but drinking plenty of water is often overlooked.
Cool down from the inside out by staying hydrated with plenty of liquids. It is recommended to drink between 1.5 and 2 litres per day.
Taking cool baths or showers will also help you keep cool, according to the NHS.
Avoid alcohol
Bad news for some, but forecasters advise against drinking alcohol in the intense heat, as well as teas and coffees, which act as diuretics and can cause dehydration.
Pyjamas in the freezer
During the day, place your pillowcase or pyjamas in the freezer. Take them out before going to bed. Hopefully they will cool you down and help you sleep better.
Throughout the day, wearing loose, cool clothing and a hat and sunglasses will also help.
And wearing lighter coloured clothes will keep you cooler.
...and flannels
Sticking a flannel in the freezer can be especially refreshing to place on your forehead as you lie in bed.
Turn on the fan
Fans can help your body regulate its internal temperature, and sticking a pan of ice cubes in front of it can make the circulating air even cooler.
If you haven't got one handy, fill a hot water bottle with cold water instead.
Dump the duvet
Thin cotton sheets will absorb sweat and are more comfortable than duvets.
Your body temperature will begin falling during the night, so hopefully you won't feel warm and uncomfortable for too long.
How to sleep better
It can be all too easy to start feeling annoyed and exasperated when you're struggling to sleep.
The best thing to do is to try to distract yourself with a relaxing activity such as reading, and try going back to bed when you're tired.
Avoid the temptation to go on your phone, as this activity can stimulate you.
Heat rises... so sleep on the lower floor
If your home has several floors, it might be worth sleeping downstairs. Spend more time in the coolest room in the house.

Try this tip from the Royal Navy
Royal Navy officers have been submerging their hands in cold water to cool down faster since the 1990s.
Research has shown colder water speeds up the rate of cooling, with core temperature reduced by around one degree for every 10 minutes of hand immersion in 15C water.
This technique has also been adopted by athletes who need to cool down rapidly when alternating between rest and movement.
Put ice on your pulse points
Applying ice to the wrists and side of the neck can help to lower body heat as the blood vessels in those areas are close to the skin's surface.
