Dr Hilary Jones has shared a trick people can use to get a good night's sleep during the heatwave.
The medical expert appeared on today's edition of Lorraine as the Met Office issued an amber warning for extreme heat. The alert will be in force for four days from Thursday, August 11, to 11pm on Sunday, August 14.
Temperatures across Liverpool are expected to reach highs of 29C and people will be searching for ways to cope in the sweltering conditions. Tuesday's episode of Lorraine was hosted by Ranvir Singh and Dr Hilary told the broadcaster how people can stay cool at night.
