Geothermal energy is equivalent to floor heating. The heating is buried underground, and then the heat is emitted and radiated upwards through the floor. Geothermal energy only produces thermal radiation. Everything in nature radiates heat to space, but this kind of radiation is different from electromagnetic radiation, which will not cause harm to human body, but is beneficial.
Water heating itself is heat dissipation, just like warm fire, or taking a hot water bottle, the effect is the same. Its thermal radiation temperature is not very high, so it can be said that it has no harm to human body. Geothermal energy dissipates heat from under the feet, which is in line with the principle that the head should be cold and the feet should be hot in traditional Chinese medicine.
Wang Yinghui, an attending physician in hematology department of provincial hospital, believes that the rumor that geothermal energy can cause leukemia or cancer is nonsense.
Extended data
Matters needing attention in geothermal heating:
1, open the window for ventilation every day.
It won't take long to open the window for ventilation in winter. A room of 80 square meters is recommended to be ventilated for 30 minutes. Experiments show that every time a room is ventilated, 60% of harmful gases in the air can be removed. If you can't open the window often, you can prepare an air purifier. ?
2. Appropriate temperature and humidity
It is found that the room temperature is usually between 18℃ and 24℃, and the humidity is between 50% and 60%. At this time, the human body feels most comfortable. The indoor temperature standard of central heating in winter in China is formulated accordingly. The national Code for Design of Heating, Ventilation and Air Conditioning stipulates that the indoor standard temperature of central heating is18℃ 2℃. Therefore, it is suggested that the floor heating temperature should be set at 23℃~27℃. ?
3. Drink plenty of water and exercise regularly
Affected by smog and heating, the air quality in winter is relatively poor, the sky is dry and the body is short of water. Pay attention to drink plenty of water, about 2 liters a day. When the weather is fine, do more outdoor sports to enhance your resistance.
People's Network-Friends Circle Geothermal heating is easy to cause leukemia or cancer Expert: Nonsense.
People's Network-Prevention: "The theory that floor heating harms people" is unreasonable.
