Fan cap, frozen spray, cooling collar ... Is these cooling "artifacts" really useful?

"Five minutes out, sweating for two hours." On July 28, 2022, the Jiangsu Meteorological ORC was upgraded to release high -temperature orange warning signals: The highest temperature in Nanjing will rise to above 37 ° C. On July 29, although it rained, the high temperature was not retreat, and the highest temperature in the southern Jiangsu area could reach 36 ° C. This is the second wave of high -heat warning in 2022. The reporter noticed that many "cooling artifacts" appeared in front of the citizens, and there were countless styles. They could find them on major e -commerce platforms. Is these "cooling artifacts" really useful? The reporter purchased several different types of "cooling artifacts": fan hats, frozen spray, cooling collar, etc. for measurement.

Fan hat: blocking line, noisy sound, average cooling effect

Holding fans and hanging neck fans are more commonplace. When searching for e -commerce platforms, the reporter noticed that the fan hat was also very popular with consumers. The reporter randomly purchased a charging fan cap. This product has more than 1,000 per month. It has a fan on the hat board. The fan has three winds adjustment to adjust the USB. According to the description of the seller, the big hat of this hat can shield more than 95%of ultraviolet rays, and the turbine cycling fan can enjoy the natural wind.

Before the reporter used this product, the body temperature was 36.7 ° C. After driving the fan to the maximum gear, the body temperature decreased by 0.2 ° C than the beginning, but it basically did not feel the coolness when used, and it could not reduce the uncomfortable feeling brought by the cool heat. In addition, after wearing this hat, the sight will be blocked, and the people wearing glasses will be more obvious. Moreover, the wind of the small fan can only be blown to the forehead, and the wind is too concentrated, which can easily cool the head. The sound of the fan is very noisy, which will affect the user's attention, and it will also disturb others in a quiet environment.

Frozen spray: good cooling effect but risk

"Calling Spray" is a cooling artifact recommended by many netizens, which are usually sprayed on clothes. But many people buy "sports frozen spray" to cool down the heat.

The reporter bought a can of spray and measured it. After spraying, the body temperature dropped directly from 36.4 ° C to 36.1 ° C. But after spraying several more times in the same body, it will obviously feel frozen. The product manual also pointed out that it cannot spray for more than three seconds in the same place, otherwise there will be risk of frostbite. In addition, the reporter learned that frozen spray is mainly an emergency measure when athletes are injured, and it is not recommended to use it as a cooling product.

Calling collar: frozen stimulation, neck frozen red, poor use

The cooling collar is also a hot cooling product. It is not large. It looks like juice popsicles. It is said that it can feel cool when putting on the neck. The reporter randomly selected one, and the seller wrote in the product introduction, "It is cold, reused, portable folding, and long -term coolness."

After receiving the column, the reporter noticed that it needed to put it in the refrigerator first. After freezing for about 20 minutes, it would become hard from the flow. Before using the cooling artifact, the reporter's body temperature was 36.2 ° C. After wearing it for 5 minutes, the body temperature was measured at 35.8 ° C. The body temperature decreases obvious, but the reporter's experience is not very good. First of all, as soon as the collar is placed on the neck, the pores of the body are immediately enlarged. In just 5 minutes, the neck will be a little frozen. In addition, this cooling collar soon returned to the form of water beaming. It is not practical to use outdoor ministers for a long time.

Mobile phone umbrella: sunscreen effect cannot be evaluated, rainproof is slightly "chicken ribs"

In addition to human cooling "artifacts", mobile phones also have exclusive sunscreen "artifacts". The reporter noticed that many takeaway riders and online car drivers will place a small umbrella near the driver's seat to cool down the mobile phone to cool down and prevent overhead and rain.

The reporter purchased a small umbrella with more than 6,000 per month. After receiving the goods, he planned to evaluate its sunscreen cooling effect. For example, under the hot sun, the use of small umbrellas will affect the temperature of the mobile phone. But Tiangong was not beautiful, and Nanjing suddenly rained. The reporter noticed that in the scene of using mobile phones outdoor on rainy days, the small umbrella is a good choice, but it also shows a little "chicken rib".

First of all, it is not suitable for groups with demand for shooting. Because the position of small umbrellas cannot be moved, the camera of some mobile phones will be blocked. In addition, it is inconvenient to hold the bracket when using a small umbrella. It is worth mentioning that if it is used when riding an electric vehicle, it will slightly block the sight, which is not conducive to safe driving; when the wind is large or the riding speed is fast, the mobile phone will still be wet by rainwater, and the small umbrella may also be possible. Blowed.
