An expert revealed you have been using fan’s all wrong and a two-second trick could help you sleep much better as temperatures soar.
Eco-design adviser Nelson Lebo, from New Zealand, revealed he only became aware of the trick when his grandmother would do it in the 1970s.
He claimed that facing the fan out towards an open window is more beneficial as it helps circulate the air around the room.
Speaking to LADbible he said: ‘Everyone knows about cross-ventilation, but it only works when the wind is blowing and then it works best when there is a direct route for the wind to blow through a home.
Cross ventilation is a form of natural ventilation that allows wind to enter one side of a room and out another.
Cross ventilation uses wind-driven force to bring cooler air from outside and replace the stale, warm interior air.
He continued: ‘What the fan does is, it forces cross ventilation, even when the wind is not blowing. A fan will also pull air around corners, as in our home.
‘The overall goal is to pull the warm air out while drawing cool air in once the outdoor temperature drops below the indoor temperature. Fans use hardly any power compared to AC.’
It comes after Sleep Advisor revealed that while fans are an ideal way to stay cool for short periods of time, keeping them on all night may have several negative impacts on your health.
And it’s not good news for those who suffer with allergies or asthma because dozing off with a fan on could end up circulating not just air – but pollen and dust as well.
The Sleep Advisor says: ‘Take a close look at your fan. If it’s been collecting dust on the blades, those particles are flying through the air every time you turn it on.’
Leaving a fan on all night can also have bad consequences for your skin – leaving it feeling and looking dry.
The constant airstream can also have the same impact on your eyes and mouth – especially for those who sleep with them partially open.
Sleep Advisor also warned the cool air could result in you waking up in the morning feeling stiff – particularly those who position the fan on their neck and face.
‘This is because the concentrated cool air can make muscles tense up and cramp,’ the experts explained.
