The voltage and current passing through electrical appliances change, which will also cause changes in the surrounding magnetic field. Therefore, all electrical appliances in the home are of such a nature. However, the radiation from a hair dryer is a type of radiation that can be ignored, and it is two different concepts from the radiation from an X-ray film. Hair dryers emit radiation, normal radiation, not very harmful radiation. A hair dryer uses a fan to blow out air. First of all, you must know that once an electrical appliance is powered on, there will definitely be an electric field. And as long as there is current flowing through it, there will be a magnetic field around the current.
One of the hazards of hair dryer radiation is damage to hair quality, which will cause the moisture content of the hair to drop. If it drops below ten percent, the hair will become rough. Frequent use of a hair dryer will reduce the moisture content of your hair and make your hair dry. Frequent use of a hair dryer can damage your hair. You can blow it until it looks 70% dry and let your hair dry the rest. Generally, many people wrap their hair with a highly absorbent towel and let it dry slowly after the water stops dripping.
Precautions for using a hair dryer
1. Make sure the hair dryer is kept away from water. It is strictly prohibited to use the hair dryer near the bathroom or other water containers.
2. Make sure your hands are dry when using the hair dryer! Do not immerse the hair dryer in water, otherwise electric leakage will occur.
3. The hair dryer will automatically power off when the overheating protection device takes effect. It can be used again after cooling for a few minutes. In order to protect the hair dryer's service life for a longer time, it is recommended that the hair dryer automatically power off if the overheat protection device takes effect. , please turn off the switch and let it cool down for a few minutes before using it.
4. Do not use the hair dryer for a long time. When the use time reaches 30 minutes, you need to stop using it for a while to prevent the hair dryer from being burned due to excessive temperature.
5. Do not block the air inlet of the hair dryer to prevent insufficient heat dissipation inside the hair dryer, resulting in reduced durability or excessive internal temperature, which may cause danger.
6. When using the hair dryer, pay attention to whether there are any abnormal phenomena. If there is an abnormal sound, there may be a problem with the motor; if there is an abnormal smell, there may be an internal problem. short circuit phenomenon. Once an abnormality occurs, you should immediately unplug the hair dryer from the socket, stop using it, and send it to a professional for inspection.
7. After each use, the power supply should be unplugged immediately. After cooling, store it in a well-ventilated, dry place away from sunlight. The hair dryer must be placed in a dry and noisy environment to prevent moisture in the air from entering the inside of the hair dryer, causing the internal insulation to decrease, causing danger and shortening the service life.
