Summer nights mean BBQs with friends, late-night dinners and drinks under the stars.
However, the downfalls of hot, lazy days include sweltering temperatures at night with many reaching for a fan to keep them cool during their sleep.
But it has been revealed that sleeping with a fan in your bedroom could be bad for your health.
Mark Reddick from The Sleep Advisor has described how a fan can “trigger asthma attacks” or “dry out eyes” as the air is moved around the room.
“As a fan moves air around the room, it causes flurries of dust and pollen to make their way into your sinuses,” he said.
This is bad news for those prone to allergies such as asthma and hay fever and is also made worse by dust collecting on the blades of the fan which is moved around the room when the appliance is switched on.

Mark also revealed that the “constant blast of air on your body” may cause dry skin along with dry eyes and is particularly problematic for people who sleep with contact lenses.
He described how some people sleep with their eyes or mouth partially open which can cause further irritation.
Interestingly, Mark explained how a constant flow of cool air on their body may also cause some people to wake up with sore muscles.
“The concentrated cool air can make muscles tense up and cramp. This problem is especially common for people who sleep with it near their face and neck,” Mark revealed.
However, Mark described how a fan can help some people drift off to sleep by creating a white noise effect which uses all sound frequencies to produce a gentle hum.
Fans can also help with boosting air-circulation in the bedroom to prevent a stale and stuffy space, according to Mark.
The NHS has described how rooms can be kept cool by closing curtains on windows that face the sun.
It states: “Keep rooms cool by using shades or reflective material outside the windows. If this isn’t possible use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter).”
