First of all, the water mattress
Water mattress is a new artifact of dormitory in summer. It contains soft ice, not water. Soft ice is made of polymer, glycerin, CMC and other materials in a certain proportion, and it is an upgraded cooling and refrigeration material. A water mattress with a height above pdd 1.5 meters is only 40 yuan, which is very cheap, and the cooling effect of the water mattress is obvious. It gradually liquefies and cools down by continuously absorbing human body heat, which is very suitable for college students.
Second, sprinkle water on the ground.
If there is no air conditioning in the dormitory, but you want to cool down quickly, you can sprinkle some water on the dormitory floor appropriately, which is beneficial to heat dissipation and cooling by using the principle of evaporation and heat absorption. But if the dormitory is paved, then you can mop the floor with a mop, and the effect is good, and it is still zero cost.
Third, the rational use of fans.
Fans are an indispensable magic weapon in summer. Some dorms may not have air conditioning, but fans are absolutely standard. Otherwise, the air conditioner does not have a fan or a fan, and it may not die of heat. We can make rational use of fans and make a simple version of "air conditioner".
Bring a basin of cold water. If possible, you can put some ice cubes in the basin properly, and then the fan blows against the current, so that the wind blows through the cold water and then blows out, which can help the dormitory to cool down quickly.
Fourth, get wet properly.
Sprinkling water yourself is also a zero-cost cooling trick, not letting you sprinkle water all over your body. It is recommended to sprinkle it on the place where our pulse is beating or pressing, because the blood vessels in these places are close, and the effect of sprinkling water is better. At the same time, it can wash the temple, the inside of elbow joint and the back of knee for about 10 seconds, and also has a good cooling effect.
Five, stick a heat insulation film or hang a sunshade.
One of the factors that lead to the increase of dormitory temperature in summer is the exposure from the sun, especially the dormitory facing west, which will be sultry in summer. Now there are transparent heat insulation films on the market, which can effectively block ultraviolet rays and thermal radiation. Sticking it to the window in the sun can effectively reduce the indoor temperature by about 2 to 3 degrees.
At the same time, many shading curtains can not only shade the light, but also have good thermal insulation, which can reflect sunlight and radiate heat indoors, so that the indoor temperature will be about 6 degrees lower. Thermal insulation film and sunshade are not expensive, and it can be easily done for tens of dollars!
