In 20 14, the seventh meeting of the Standing Committee of the 12th National People's Congress deliberated and passed the new regulations, requiring heating enterprises to ensure that the temperature of users' bedrooms and living rooms is not lower than 18℃ during the heating period. At present, this temperature standard is widely used in central heating areas in China to ensure that users get a warm and comfortable indoor environment.
The most suitable air conditioning temperature for human body should be 24℃ to 27℃, the lowest temperature should not be lower than 22℃, the indoor and outdoor temperature difference should not be greater than 5℃, and the air conditioning at night should not be lower than 24℃. If the air conditioner is turned on too much and the indoor temperature is too low, it is easy to suffer from "air conditioning diseases", such as colds, coughs, fever and listlessness.
Therefore, the country put forward the slogan of saving air conditioning temperature at 26 degrees. At this temperature, people feel neither hot nor cold, and air conditioning is more energy-efficient. If the temperature is too low, it is easy to cause the accumulation of fat, which is not conducive to weight loss.
Extended data:
Influence of temperature on human body;
33℃- Sweat glands start working at this temperature for 2-3 hours, and the human body is in an "air-conditioned state"-sweat glands begin to emit accumulated body temperature through slight sweating.
35℃- the heat dissipation function reacts immediately. At this time, the superficial vein dilates, the skin sweats, the heart beats faster, and the blood circulation accelerates. For some elderly and infirm people with poor heat dissipation, it is necessary to cooperate with local cooling or turn on indoor air conditioning to reduce human body temperature.
36℃- 1 alarm At this temperature, the human body "cools itself" by evaporating sweat to release heat. Sweat, sodium, vitamins and other minerals will be excreted every day, and the blood volume will also decrease. At this time, drinks containing salt, vitamins and minerals should be supplemented in time to prevent electrolyte disorder in the body, and other cooling measures should also be started.
38℃—— When the second alarm temperature rises to 38℃, human sweat glands sweat, making it difficult to ensure normal body temperature. Not only does the lungs "gasp" and exhale heat, but even the heart should speed up and output 60% more blood to the body surface than usual to participate in heat dissipation. At this time, cooling measures, cardiac drug health care and treatment can not be relaxed at all.
39℃-3 alarm sweat glands are working hard, and it is easy to have a heart attack at this time.
40℃-4 alarm. The high temperature has made people dizzy. At this time, people must immediately go to a cool place or use ice cubes to cool down. People who feel unwell need to be sent to hospital immediately for treatment.
4 1℃- Five-level alarm for perspiration, respiration and blood circulation? All the organs that can participate in cooling are close to the limit after full load. At this time, it is a "shock temperature" for frail patients and the elderly, so we must be extra careful.
The alarm of 42℃-6 indicates that the human body can't breathe, so it is necessary to use ice cubes to cool down, otherwise it will kill people.
