Ways to cool a room without using air conditioning

The North is experiencing the hottest days of summer, with the highest temperature reaching 38-39 degrees Celsius. So how to cool the house without turning on the air conditioner? Please refer to the ways to cool the room below.

Homemade air conditioner

VnExpress quoted Aboluowang as saying that making your own air conditioner at home is actually quite simple. All you need is a fan and ice. Use 2-3 bottles or plastic cups filled with water and 3 teaspoons of salt (about 50g), shake well to dissolve completely. Place the bottles of salt water in the freezer (salt prevents the ice from melting quickly). Place these bottles of ice water about 15 cm in front of the fan. The wind blowing from the fan will evaporate the water, reducing the temperature. When the bottles of water melt, you can put them back in the refrigerator and reuse them many times. This method is cheap and quite effective.

Always draw the curtains

According to scientific research, 30% of unwanted heat comes from windows. Therefore, the simplest solution is to always close the curtains and you should also choose curtains with dark colors to prevent heat radiation from entering the room. With this simple measure, you can help reduce 7% of the cost on the electricity bill and keep the room temperature low. Pay special attention to glass windows and those facing West and South.

Close and open the room door at the right time

According to an article on Zing News, during hot times of the day, closing unused rooms in the house will prevent cool air from "wasting" in these spaces.

At cool nights, you can open them to take advantage of natural air circulation.

Change the bed sheet

Changing your bedding with the seasons not only freshens up your bedroom, it’s also a great way to cool down. While wool or synthetic fabrics are warm, cotton sheets will keep you cool and comfortable in hot temperatures.

Switching to a mat, or using pillows or water mattresses is also an attractive cooling option for the hot summer. However, you need to check and choose to buy good quality products to avoid breakage and water leakage when using.

Cool your body instead of the room

Instead of focusing on cooling the room, we can focus on cooling our bodies. Some simple measures are wearing cool clothes, using cold towels on hot body areas such as the neck, inside the elbows, drinking cool drinks to cool down.

Turn on exhaust fans in the kitchen and bathroom

This is essential because it helps to remove hot air from cooking or after you take a shower from your home.

Plant more trees

Adding more potted plants in the house, or designing a climbing plant trellis on the balcony will have a great effect in reducing the temperature in the house. Green plants also have the effect of preventing dust and filtering the air, helping you feel more comfortable on hot days.

The roof is made of light-colored materials.

For hot and humid climates, the choice of cooling materials that are effective in reflecting solar energy rather than absorbing it should be considered.

In terms of reflectivity, white metal roofing can reflect 66% of solar energy. Compared to other roofing materials, metal roofing cools faster at night and retains heat for a shorter period of time. In addition, flat white concrete tiles, terracotta tiles or clay tiles can be used for roofing.
