Common mistake made between 11.00-18.00 on hot summer days makes the house even hotter

With the arrival of the summer months, air temperatures reaching dangerous levels push millions of people who want to keep their homes cool into a common search. The common methods applied, especially in the morning and afternoon hours, can often make the situation worse instead of providing the expected relief. This situation arises from ignoring the basic principles of heat transfer. This habit, which affects the masses, not only reduces individual comfort but also negatively affects energy consumption. Experts point out that small but correct measures to be taken during the hours when heat waves are felt most intensely can save lives.

According to scientists, the hottest time of day usually occurs between 11.00 in the morning and 18.00 in the afternoon. Many people make the mistake of opening their windows wide to change the air in the room between these hours. However, since the outside temperature is much higher than the shaded and cool air inside, the opened windows act like a heat funnel. The scorching air outside absorbs the coolness inside in seconds, making the environment suddenly stuffy. This sudden air current completely disrupts the heat balance inside, causing extra effort and energy to be spent.

At the basis of this common mistake lies the false perception that the air accumulated inside the house is 'hot' and needs to be expelled outside. However, the walls and insulation of buildings serve to temporarily separate the cool air inside from the extreme heat outside during the day. When windows are left open, this protective shield is disabled, and the inner walls and items of the house start to heat up quickly. Especially during the hours when the sun's rays hit directly, the light entering through these windows rapidly increases the temperature of the items in the environment. For this reason, those who want to protect the natural cooling mechanism of the house must keep the windows and curtains tightly closed during these hours.

The most effective way to keep the interior cool is to isolate the house from the outside world starting from the morning hours when the sun begins to rise. Lowering wide shutters, thick curtains, and blinds prevents direct sunlight from entering, significantly curbing the temperature increase. The operating performance of the air conditioner also depends on this insulation; air conditioners operating when the windows are closed can bring the environment to the desired temperature in a much shorter time by consuming less energy. Otherwise, running air conditioners at full speed against a constantly open window not only multiplies electricity bills but also shortens the lifespan of the devices. At night, when the temperature drops, all windows should be opened wide to allow clean and cool air to enter the house.

In summary, adopting a different lifestyle rhythm according to the hours of the day is of great importance to reduce the effect of summer heat. The extreme hot air outside absolutely must not be let in between 11.00 and 18.00 during the day. During these hours, not only should the house be closed off to the outside, but heavy physical activities and the use of heat-emitting home appliances such as ovens should also be avoided. This simple strategy, applied from morning to evening, ensures that natural coolness is trapped inside the house and preserved until the night hours. Everyone who wants to spend the summer months in a healthy, fresh, and energy-efficient way must consciously apply this basic rule.
