Why is it better to use a fan in summer than to blow an air conditioner?

On a hot summer day, the first thing to do when you get home is to turn on the air conditioner to enjoy the cool. But for the sake of health, it is better to use a fan than to blow an air conditioner. I'll tell you why fans are better than air conditioners in summer. Welcome to reading.

First of all, the benefits of shaking the fan

1 shake off scapulohumeral periarthritis

Flapping is a kind of upper limb movement, which requires the cooperation of fingers, wrists and local joint muscles. Rocking the fan can keep away from the fan and air conditioner, exercise the shoulder joint and strengthen the strength and coordination of the muscle ligament of the shoulder joint.

Shake the qi and blood of the whole body

As the saying goes, "ten fingers are connected to one heart." According to the meridian theory of traditional Chinese medicine, the ends of ten fingers are connected with six hand meridians, which are connected with the heart, lungs and brain respectively. When shaking the fan, the stimulation of the acupoints of fingers and palms will inevitably make the blood gas run smoothly.

3 prevent colds

The electric fan has large air volume, strong and concentrated wind speed, while the air conditioner attacks people with cold air. If the elderly are not careful when using it, they will catch a cold and even cause facial paralysis. The elderly can control the speed of wind speed and air volume according to climate change and their own health status, which can benefit and avoid disadvantages and prevent diseases.

4 Get rid of emotional diseases

Psychological research shows that people's emotions, moods and behaviors are related to seasonal changes. In hot summer, many people will have mood swings, especially middle-aged and elderly people, which are prone to mood disorders. Whether blowing air conditioners or fans, most of them are indoors, and a person is bored at home.

In the era when there was no air conditioning, everyone sat under the big tree and shook their fans to enjoy the cool. It is also a great pleasure for middle-aged and elderly people to chat and comment on ancient and modern times while enjoying the summer.

5 Prevention of cerebral hemorrhage

Heatstroke is a common disease in midsummer, which has a lot to do with improper use of air conditioning. If the temperature of the air-conditioned room is adjusted too low, which is quite different from the outdoor temperature, it will cause cerebral blood circulation disorder, stroke or other vascular diseases in the elderly, especially those with hypertension and arteriosclerosis.

Fan the left hand to protect the heart and prevent cerebral hemorrhage, which is also the most important function of shaking the fan. Lin Hexi said that shaking the fan is a kind of unilateral limb exercise and also an exercise for cerebral blood vessels. It can not only exercise the joints and muscles of limbs, but also exercise the contraction and relaxation functions of cerebral vessels.

Because the control of the brain on the body is cross, that is, the left hemisphere dominates the right limb and the right hemisphere dominates the left limb. Most people are used to using their right hand for a long time, and their left hand exercises less, which leads to the lack of exercise in the right hemisphere. Most of the cerebral hemorrhage in the elderly occurs in the right hemisphere, which is also the reason why the blood vessels in the right hemisphere, which dominate the activities of the left limb, are not exercised and appear fragile. Therefore, shaking the fan with your left hand often in summer can promote the function of the right brain, enhance the elasticity of blood vessels in the right hemisphere, and effectively prevent the occurrence of cerebrovascular diseases.

Second, the disadvantages of blowing air conditioners

1 Blowing air conditioning can easily lead to facial paralysis.

Blowing air conditioning during sleep leads to facial paralysis. Recently, a young man with a strange expression and crooked mouth came to Nanjing Gulou Hospital for treatment. Experts in the hospital said that after the summer, the number of patients with facial paralysis admitted to the analgesia department and acupuncture department of the hospital increased significantly, mostly because of gluttony.

Blowing air conditioners causes colds and rhinitis.

It's easy to catch a cold in summer, coupled with the dry weather and high temperature these days, many people suffer from rhinitis. Most rhinitis is caused by a cold. If a person is weak and vulnerable to bacteria, colds will occur frequently. Once there is a long-term nasal congestion, be careful that rhinitis will find you.

3 Women who blow air conditioners for a long time are prone to menstrual disorders.

In summer, girls often like to go to work barefoot in sandals and spend a day in an air-conditioned office. When I get home, I often leave the air conditioner on all night. After a period of time, many women suddenly found themselves with menstrual disorder and unbearable abdominal pain.

Women who often sit in the office, especially young women, may affect ovarian function and ovulation disorder if they are exposed to cold air for a long time, which may lead to menstrual disorder, abdominal pain and abdominal distension.

Blowing air conditioning is easy to induce cervical spondylosis.

The incidence of cervical spondylosis has no obvious seasonality, but the changes of season and environment have certain influence on cervical spondylosis. For example, a hot and humid environment will aggravate the condition. In summer, the air is humid, and "sauna days" often appear, which is a factor affecting the condition. At the same time, in order to achieve the purpose of "cooling down", many people turn on the air conditioner to a very low temperature. If the cold air just blows on the back or neck, it will aggravate the condition of the cervical spine.

Third, the use of air conditioning skills

● The air conditioning temperature should not be too low. Generally, it is advisable to control it at around 25℃, and it is advisable to keep it 3℃-5℃ lower indoors than outdoors.

● Drink plenty of boiled water in the air-conditioned room. Boiled water such as honeysuckle, chrysanthemum and rehmannia can be used as tea to clear away heat and detoxify.

● Limit air conditioning time. Even if it is hot, don't leave the air conditioner on all day, let alone let it blow directly.

● Pay attention to keep the indoor air fresh. Ventilation the room regularly, at least once in the morning and evening, each time 10-20 minutes. At the same time, avoid smoking in air-conditioned rooms. Even if the air conditioner is on, it is best to open a small gap in the window for ventilation.

● Go in and out of the air-conditioned room and change clothes at any time. When you sleep at night, cover with a thin quilt or towel quilt, especially when your stomach is tight.
