How to cool a room using only two bottles of water.

Every year, summer brings scorching heat that leaves many feeling stifled and exhausted. For affluent families who can stay indoors with air conditioning on 24/7, this isn't a problem. However, for lower-income families, or even students renting small rooms without air conditioning, the excessively high temperatures are nothing short of torture.

The Education Times, citing World Of Buzz, reported that a Japanese man named Hirokouji Kanpo, whose Twitter address is @hirokoujiKanpo, shared a simple and useful way to cool a room without air conditioning.

Hirokouji Kanpo's sharing received enthusiastic "likes" from netizens. Specifically, according to Hirokouji Kanpo's instructions, we need to prepare two 500ml bottles of water and then follow these three steps:

- Step 1: Fill both bottles with water to about 3/4 full (be careful not to fill them completely).

- Step 2: Place the two bottles of water in the freezer and wait until the water inside is completely frozen.

- Step 3: When the weather is hot, take out two bottles of water, put them in a metal bucket, and leave it in the room.

Hirokouji Kanpo stated that simply doing so would make the room drier and cooler. According to Hirokouji Kanpo, the room becomes cooler due to the dehumidification process.

In addition, pharmacist Hirokouji Kanpo also reminded everyone not to fill water bottles completely, because when water freezes, its volume will increase beyond the level of water poured into the bottle, causing the ice to bulge and damage the bottle.

How to cool a room without using air conditioning.

Besides the method above, you can also apply some other ways to cool a room without using air conditioning, as listed below:

Plant more trees.

Adding more potted plants indoors, or designing a trellis for climbing plants on the balcony, will greatly help reduce the indoor temperature. Plants also help trap dust and filter the air, making you feel more comfortable on hot days.

Adjust the ceiling fan to rotate counterclockwise.

In the summer, setting the ceiling fan to rotate counterclockwise creates a gentle breeze; when standing under the fan, you will feel a direct stream of cool air on your body, with the cool air concentrated and not dispersed throughout the room.

Change your mattress when it's hot.

A simple way to cool down your rented room and ensure a comfortable, non-sweating sleep is to remove all mattresses and sheets and replace them with bamboo mats or cooling mats. Changing from a bed to the floor and placing a mat on the surface helps align your spine naturally, and you'll feel cooler.

Instead of resorting to high-end gadgets when you're on a tight budget , start by cooling yourself down. Choosing the most breathable clothing to wear at home and showering before bed are effective ways to instantly lower your body temperature.

Close the windows and draw the curtains.

During hot hours, close all windows to prevent hot air from entering the house, then close the curtains to reduce the heat somewhat. When it gets dark, open all the windows to allow for ventilation.
