As the days grow longer and the temperatures start to slowly get slightly warmer, it's safe to say that spring is finally here.

And that means it's time to change our sleeping habits to make sure we're not too hot when trying to nod off, including saying goodbye to the toasty winter duvet in favour of a lighter version.

But it can be hard to know when to make the switch, as you don't want to go too early and end up chilly - but thankfully James Higgins, CEO Ethical Bedding, has revealed the exact date we should be changing our bedding - and it's sooner than you think.

According to statistical data on the average daily temperatures from March to April over the last eight years in the UK, there is a 28% increase in heat when moving into the month of April - and James has insisted that you don't want to wait until a heatwave to change your duvet.

He said: "When we looked into the data, there were a few factors which made it visibly clear when could be a good time to look at switching out your duvet tog from a winter thickness of around 10.5-15 togs, to a summer thickness of 4.5-7 togs.

"Firstly, the first week moving from March to April of 2022 showed around an 18% increase in average daily temperatures, which can make a huge difference to the heat retention in your room.

"Furthermore, looking at a daily breakdown of April in 2021, the 20th April marked temperature lows of just 14C at night, the highest level commonly seen throughout April.

"Based on these figures and historical weather routines, we would advise that people look to swap their bedding on the second weekend of the month, which will be Saturday, April 15."

James also recommends that sleeping with a tog between 4.5 and 7 can "help your body control temperatures in a smaller space", so if your bedroom is small, don't fear.

When browsing duvets, it can be helpful to have an idea of what the different tog ratings mean. The scale ranges from 1 to 15, with 1 being very cool and 15 being the warmest – but most duvets start at 4.5.
