It's important to keep yourself, your loved ones and your home cool at this time of year.
But some of us are making big mistakes in our mission to chill.
This includes everything from where you place your fan, to when you should have windows open and even how you shower.
We spoke to one of Dyson's top engineers, who works on fans, to find out the best ways to beat the heat.
Where to put your fan
The position of your fan around the room can make all the difference.
And the wrong spot could just be blowing warm air your way, which will only make matters worse.
Shawn Navarednam, Environmental Care Design Engineer at Dyson, says the corner of the room is best.
"Positioning your fan in the corner of the room means the air can be projected diagonally across the room," he says.
"However, should you wish to find relief from a hot summer night, you can position the fan next to your bed pointing towards to you to provide a cooling effect.
"The Dyson Cool Tower Fan can be programmed to turn off after pre-set intervals, from 15 minutes to 9 hours, perfect for summer slumbers."
The height of your fan can make a difference, too.
Cooler air is denser and accumulates at the bottom of the room, so keeping your fan near the ground to sweep the cold air up can help.
FAN MISCONCEPTION
Whilst fans cool you and circulate air around the room, they are not air conditioning units so will not lower the temperature of your room.
They will however provide relief by cooling you with powerful airflow, facilitating the evaporation of sweat and by replacing warm air with cooling air.

Don't take a cold shower
Contrary to popular belief, an ice cold shower won't help you stay cool - at least for the long term.
A warm shower actually works better.
"Surprisingly, consider taking a warm shower rather than an ice cold one," Shawn explains.
"When the body is subjected to extreme cold, it tries to regulate its core temperature by controlling blood flow to the skin.
"This means that although a cold shower may offer a brief moment of respite, heat can be retained within the body.
"Following a lukewarm shower, the body will try to cool down and accelerate blood flow to the skin, which promotes heat loss."
Don't have windows open all day

Letting in the sunlight might brighten your mood but it can create a greenhouse effect – with up to 30 per cent of unwanted heat gain coming from windows.
So it's best to keep the windows, curtains or blinds closed during the day to minimise the amount of sunlight coming in.
"Night-time is when summer temperatures tend to dip, so make a habit of opening windows at night to allow cooler air to enter," Shawn continues.
"Then be sure to close them in the morning before temperatures rise and open them again in the evening as the temperatures gradually drop."
Experts warn of 6 HUGE mistakes to avoid when using a fan
Unplug electronics
Electrical appliances and gadgets generate heat.
These days we have so many around the house that collectively contribute to the ambient temperature of the room.
"Opt for energy efficient lights and get into the habit of turning off and unplugging all electronic devices that are not being used," Shawn says.
"Cooking in a pan or oven can also increase indoor temperatures, so opt for a lighter meal or one that can be cooked outside such as a barbecue."

Typical Brit spends more than two whole days a month in total procrastinating
See the top 20 tasks Brits avoid below KILLING TIME Typical Brit spends more than two whole days a month in total procrastinating Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) THE typical Brit spends more than two whole days-a-month in total procrastinating. Research found they typically avoid 'tedious' tasks 17 times a week - with 32 per cent declining to do certain jobs for several months or more. Sign up for Scottish Sun newsletter Sign up 2 DIY is among the tasks Brits put off Credit: SWNS 2 We also tend to put off booking appointments Credit: Getty Sending back online shopping returns, paying bills, and doing DIY are among the tasks they're most likely to stall on. A third (33 per cent) avoid tasks because they're 'easily distracted', with a further 47 per cent doing so because they're 'boring'. Commissioned by which offers deals on holidays, flights, and hotels, the poll, of 2,000 adults, found 23 per cent have resorted to taking annual leave in order to get on top of all the tasks they've been avoiding. But procrastination isn't always problematic - 39 per cent actively prefer to leave things until late on, with 14 per cent of the opinion they get better results when they do so. Psychologist Emma Kenny, who has teamed-up with the travel operator, believes procrastination can improve patience and also helps people feel more grateful. She said: "Procrastination isn't simply about laziness, it's often a coping mechanism for feeling overwhelmed. 'But while chronic procrastination can increase stress, the 14 per cent who report better results under pressure may actually be leveraging their natural work rhythms. 'The key is distinguishing between productive delay and avoidance that creates genuine problems." Of those who ever procrastinate - which is 89 per cent of adults - the study found 50 per cent do so more with personal tasks and 11 per cent do so more with work-related tasks. However, 30 per cent avoid certain jobs in both walks of life - at work and at home. Other tasks they regularly put off include responding to emails, updating their CV, and even going to sleep. Many also stall on replying to personal messages like texts and WhatsApps, going to the gym or exercising, and backing up devices or updating software. Emma Kenny added: 'Procrastination is a natural, human trait and whilst it can make people feel guilty, it can also give us space to think clearly about choosing the right moment and to process the idea and holiday plans properly. 'When you change the narrative from 'I still haven't done it' to 'I just found an incredible last-minute deal', procrastination becomes a passport to adventure.' It also emerged 83 per cent have procrastination tactics they actively employ - including starting jobs at a 'nice round number' like 3pm or 4pm (27 per cent). More than a fifth (22 per cent) will hold off doing anything until it's 'absolutely essential' a task needs to be completed. And 25 per cent will do something else which doesn't need doing - like intensely researching something which could wait - to avoid sitting down to tackle a task. The research, carried out through OnePoll, found 27 per cent make a mindful and conscious decision to procrastinate so they can enjoy the feeling of anticipation for as long as possible. Zoe Fidler, spokesperson for said: 'It's clear to see that us Brits are a procrasti-nation. 'Some people even prefer it, saying putting things off helps to build excitement, anticipation, and the threat of a deadline getting tasks done faster. 'And when it comes to holidays in particular it's never too late to book one - in fact, one in five of our customers book within just 72 hours of departure.'

Third of Brits would end date over a condiment clash as Aldi releases innovative new sauce
Nearly a third of Brits admit they would end a date over a condiment clash, new research reveals. Exactly 32% made the culinary admission, with only half (54%) believing a relationship can survive differing sauce loyalties The country is fiercely divided over sauce habits, with two-fifths (40%) saying sauce preferences reveal something about a person's personality. According to research from Aldi, the nation is also home to a significant clique of enthusiastic sauce mixologists. Seven in ten enjoy mixing sauces, with ketchup and mayo the go-to pairing for 43%. Three in five (59%) go a step further, admitting to whipping up their own custom blends at home – with almost a quarter (24%) doing so 'regularly'. In light of the research, this summer, Aldi is giving the nation the culinary contraption they never knew they needed: a limited-edition triple-sauce bottle that squeezes ketchup, mayo and mustard at the same time for one perfect, triple-hit mouthful. The three-in-one bottle, named The Mighty Trio, launches as new research reveals just how passionate – and opinionated - Brits are about their condiments. Unsurprisingly, almost three quarters (72%) of Brits would therefore be eager to try Aldi's new invention serving all three sauces at once. But not everyone's mixing it up. A quarter prefer to keep sauces separate. 15% say ketchup on pasta should be outlawed altogether – just one of the many 'sauce crimes' Brits have witnessed. Top culinary offences include drizzling sauce on ice cream (14%), a roast dinner (12%), fruit (11%) and even cereal (10%). But the judgement doesn't stop at what you pair your sauce with. Three in five Brits are dippers, and over two in five (45%) admit to secretly judging how others apply sauce – whether it's the technique, the quantity, or the 'on top' approach rather than dipping. Perhaps this explains why we don't trust others to sauce our food – with 72% saying they feel anxious when someone else does it for them. Almost one in three (32%) have even skipped asking for a sauce at a restaurant to avoid judgement, and 42% of Brits have confessed to packing their own bottles when travelling or dining out. But the ultimate dealbreaker this summer? 84% of Brits would consider walking out of a BBQ with no ketchup. For those prepping the perfect Bank Holiday gathering, Aldi's range of condiments, including Bramwells Tomato Ketchup (89p, 550g), Bramwells Squeezy Real Mayonnaise (95p, 500ml) and Bramwells American Style Mustard (99p, 290g), means no one will be left disappointed. Aldi UK's Julie Ashfield said: 'It's clear Brits love their condiments, with a huge number of sauce mixologists whipping up their own concoctions at home. 'The Mighty Trio is Aldi's answer to the BBQ juggling act, giving you all three classic condiments in one easy squeeze. It's fun, practical and the ultimate hack for anyone who likes their burgers, hot dogs or chips with a little bit of everything!' To enter the competition to win a trio sauce bottle, shoppers should email mightytrio@ with their full name before 28 th August 2025.
