Hot summer is always inseparable from the air conditioning, whether in the office or at home, air conditioning has become a summer necessity. Many people feel that the air conditioning temperature is high, it loses the meaning of air conditioning, so many people like to sleep with the air conditioning on to 16 ℃ and then wrapped in blankets to sleep. This practice can cause air conditioning disease, what are the symptoms of air conditioning disease?
The dangers of air conditioning
The number of people suffering from respiratory diseases in the summer is increasing year by year, which is related to people in the air-conditioned room environment for a long time, on the one hand, the temperature of the air conditioner is too low, on the other hand, the air conditioner is not cleaned in time is easy to breed bacteria, is the human immune system is reduced. Nasal congestion, runny nose, headache, insomnia, endocrine disorders, etc. are typical symptoms of the so-called air-conditioning disease. Although the human body has a certain ability to regulate body temperature, there is a limit to this ability. The effect of temperature on the skin is through the action of the human nervous system, which causes a thermoregulatory effect, causing the human blood vessels to contract or diastole to maintain a constant body temperature. Low room temperature will also make the human skin vascular, sweat and sebaceous glands contraction, resulting in neurological disorders, manifested as dizziness, easily tired, general discomfort, mental discomfort and reduced immune function. Especially prone to colds, gastroenteritis, frozen shoulder, facial nerve paralysis and other diseases, but also the cardiovascular and cerebrovascular patients are a big taboo.
Cover the quilt blowing air conditioning can not prevent disease
Many people like to turn on the air conditioning temperature to the lowest and then wrapped in a quilt to sleep, this practice can only prevent freezing but not disease. When people sleep, the body's metabolism slows down, the air conditioning temperature is too low, it is easier to be attacked by germs, cold air from the respiratory tract into the body, people will find themselves after waking up dry mouth and nose, headache, heavy sneezing, runny nose, and even suffer from serious respiratory diseases.
Long-term blowing air conditioning susceptible to respiratory diseases
The respiratory tract is the most fragile in the human body. When the air conditioning temperature is too low, it is easy to break the fragile defense of the respiratory tract, and in light cases, coughing, sneezing, runny nose and other cold phenomena occur. If the air conditioning temperature is too low, serious cases will cause pneumonia, especially when working and studying under central air conditioning, etc. The incubation period is usually 2 to 12 days, and although there is no reaction to respiratory diseases, there is fever, coldness, muscle aches, dry cough, no or little sputum, and if not treated in time, there will be fever and dry cough, and serious death due to respiratory failure.
Long-term air conditioning is not good for the nasal mucosa
Long-term blowing air conditioning, the relative humidity is also significantly lower, so that the human eye and nasal mucosa is not conducive. When people feel dry nose and throat, they should be careful of the invasion of viruses. At the same time, the house dust, dust mites do not flow out, allergic people are also prone to allergic reactions, in addition to the air conditioning temperature can not be too low, should often open the window ventilation, to maintain air convection.
Long-term air conditioning leads to neurological imbalance in the brain
People who often sit in air-conditioned rooms will feel dizzy, dizzy, bleary-eyed and often forgetful, which is a common neurological imbalance in the brain caused by low air conditioning temperature. In addition to causing people to catch a cold, the damage to the brain caused by low air conditioning is also quite serious. Although the anions contained in the air can inhibit the central nervous system and relieve brain fatigue. However, the air conditioner adsorbs too many anions, making more and more cations in the room, and the imbalance of anions and cations also makes people's brain nervous system follow the disorder and imbalance.
Long-term blowing air conditioning easy joint cold
Long-term blowing air conditioning is easy to cause joint pain. Summer outdoor air is hot, people generally wear less, but indoors, the air conditioning temperature is too low, and thin clothing, such a low-temperature environment will stimulate rapid vasoconstriction, causing poor blood flow, resulting in joint damage, cold, pain, etc., some even stiff neck and back, waist and limb pain, cold hands and feet numbness and other phenomena.
Long-term blowing air conditioning is likely to cause skin eczema
Many long periods of time without the use of air conditioning, the filter has adsorbed a large amount of dust, mold, etc., with the air conditioning fan blown into the room, laid on the human skin or inhaled into the human body, due to indoor air conditioning and closed environment, poor air circulation, it greatly increases the chances of eczema triggers. In addition, a long time the air conditioning temperature is too low, will produce a lot of condensation, making the air increasingly dry, and most of the skin exposed, accelerating the loss of skin moisture, is also the main cause of eczema recurrence.
Air conditioning set at 26℃ is the most appropriate
When the ambient conditions are 25℃, 50% relative humidity and 0.15m/s airflow speed, the human body is in the most normal and ideal thermal equilibrium state, that is to say, it feels the most comfortable and responds most appropriately. The human body feels the effective temperature, than the temperature of the indoor air to be correspondingly slightly lower, generally about 1 ~ 2 ℃, that is, the air conditioning air temperature is slightly higher, but, the actual human body does not feel the temperature is that high. Therefore, the control temperature of the air conditioner is adjusted to about 26 ℃, when the human body will feel more comfortable.
