A smart trick with fan, which offers coolness on hot nights, experts suggest, is low cost and highly efficient.
It is known that when the temperature rises, the nights become difficult for those who do not have air conditioning or do not want to turn it on, either because it is difficult for them to breathe, or because the cost of electricity has soared.
However, there is the smart trick with fan, which is nothing more than the technique of cross-ventilation or otherwise releasing heat, offering cool.
How to apply the clever trick with the fan
All you need is a floor fan, which can be placed opposite an open window, ie instead of the fan blowing directly on us while we are lying in bed, the secret is to turn it so that it "sees" an open window.
New Zealand-based environmental design consultant Nelson Lebo advises placing the fan on a shady side of the house, facing the window, as soon as the outside temperature drops below that inside the house.
This technique activates the cross-flow of air, where essentially hot air is blown out of the house and cool air is allowed to enter.
For Nelson Lebo, this method is more practical than placing the fan in front of us while we sleep, a practice that dries the nose and airways, and can also be annoying due to noise.
