Laura Tobin has revealed that she's previously found her dinner party guests doing star-jumps in her living room in a bid to warm up.
The Good Morning Britain star, 40, has admitted that she's not a fan of turning the heating on in her home due to energy costs - even when her guests are shivering with the cold.
In her brand-new book, Every Day Ways To Save The Planet, Laura recalled a hilarious encounter she had with her friend while they were over visiting her 'freezing' home.
The ITV star explained: "The biggest use of energy in our homes is from heating (and cooling if you live in a warmer climate). Lowering your thermostat by a degree is a well-known money-saving tip - the less heat you generate, the less energy you use, and the less money you spend.
"This of course, also means a reduction in the amount of greenhouse gases your home emits.
"A study in 2020 showed that almost two-thirds of Brits had their thermostats turned up to more than 20 degrees. Well, not in my house. Everyone who knows me expect my house to be cold and if they come and visit, they bring extra layers.
"Once, me and my husband came back to our living room to find our friend doing star-jumps to keep warm. Technically, according to my husband, we have the heating 'on' all the time, but we have the thermostat set to 16 degrees, so it doesn't click on unless it dips below that temperature.
"Sometimes, we even have thermostat wars. My husband can hear the 'click' as the heating switches on from a mile away.
"If I'm cold, I'll click it on, and he will then click it off. And it's very rare that we will ever have the heating on before November - it's just not allowed. However, things have changed since we have had Charlotte of course. We do turn up the thermostat to 18 degrees in the cooler months now. 19 would be pushing it and 20 degrees is as high as it will ever go."
Laura went on to share some savvy advice about saving money on energy bills when it comes to heating.
The meteorologist revealed that if families turned down their thermostat by a mere one degree, over the course of a year, they would save up to £40 off their annual energy bill.
By doing this, families would also cut their carbon footprint by a whopping 300kg CO2 - which is the equivalent of 754 miles in a car.
Laura also advises to set a timer when it comes to heating and to turn off radiators in rooms which are not being used.
The thrifty life hacks are all part of her new book, Everyday Ways To Save Our Planet, released by Mirror Books.
Within the pages, Laura offers plenty of tips and tricks to help people make a difference to saving the planet by making small everyday changes to their routines - including recycling, organising food waste, and cutting down on the use of plastics.
Throughout her informative book on climate change, Laura insisted that she will do everything in her power to make the world a better place for her daughter, and hopes that in time, the damage that has been done to the planet can one day be reversed by the actions of people who take being eco-friendly seriously.
The meteorologist shared a number of shocking statistics in her new book - one in particular which stated that the UK only recycles 47% of it's plastic waste.
Laura Tobin: Everyday Ways To Save Our Planet, RRP £14.99, is out on 7 April and published by Mirror Books.
