Causes of colds during the dog days of summer

The symptoms of a cold during the dog days may be caused by using the air conditioner for too long. Because the weather is hot, many people like to take off their clothes and sit in front of the air conditioner, which makes it easy to catch a cold. It is mainly due to the alternation of cold and heat, which will cause an increase in moisture in the body, thus causing a cold. In the event of a cold during the dog days of summer, it is recommended that you take care to protect your body and not sweat directly in front of the air conditioner.

In fact, one of the reasons is that when people should sweat on hot days, because they are in an air-conditioned environment, the sweat cannot evaporate, and the external cold and internal heat are intertwined to form dampness.

What to do if you can't give up the coolness of air conditioning? Then do aerobic exercise and sweat actively!

Sweating during exercise is active sweating

When the ambient temperature reaches around 33°C, people will sweat in a quiet state in order to increase heat dissipation and thus maintain a relatively stable body temperature. Therefore, the sweating at this time is passive sweating, also known as "superficial sweating".

During exercise, the human body produces a lot of heat, blood circulation speeds up, and takes away a lot of heat. Sweating during exercise is “deep sweating”.

What is the use of deep sweating?

1 After experiencing the cool autumn, cold winter and damp spring, the body's yang energy has been suppressed for a long time, and a lot of cold and damp air has accumulated. During the dog days of summer, people's pores are wide open and they are most likely to sweat, which is a good time to eliminate cold and dampness from the body.

Doing aerobic exercise and actively sweating can remove the cold and dampness accumulated in the body, which is beneficial to reducing disease and prolonging life.

2 Carcinogens such as lead and other toxic substances and wastes in the human body, as well as toxins and dirt on the body surface, can be excreted through sweat. This is why people feel refreshed after sweating during exercise.

3. Stick to physical exercise and sweat actively at least once a day, which is beneficial for the treatment of high blood pressure.

In addition, through exercise, the heart rate slows down significantly, thereby reducing the burden on the heart, reducing myocardial oxygen consumption, and avoiding the occurrence of cardiovascular disease.

4Exercise during the dog days of summer can improve the function of the respiratory organs and ensure the body's metabolic needs. Exercise can increase saliva secretion, improve people's appetite, and keep bowel movements smooth, which is beneficial for preventing and treating digestive tract diseases.

How to exercise properly?

Recommended activities: low-intensity aerobic exercise, such as swimming, playing table tennis, jogging, brisk walking, etc. Middle-aged and elderly people can choose to take a walk, do light gymnastics, or do Tai Chi.

Intensity: Exercise to the point where you are slightly sweating, slightly out of breath, and can still hold a conversation easily.

Warm reminder: You must learn to sweat properly and also learn to replenish water properly. After sweating a lot, you must replenish water and salt. You can drink light salt water or sports drinks.

Due to physical aging, middle-aged and elderly people are more likely to develop serious illnesses such as cerebral thrombosis and myocardial infarction during exercise. Therefore, middle-aged and elderly people should exercise moderately! Especially those with high blood pressure, heart disease and other cardiovascular and cerebrovascular diseases are not suitable for exercise during the dog days!

In addition, many people always feel a little strange in the summer.

Sometimes it just hits...

Sometimes I feel depressed...

What is the reason?

(,,•́ . •̀,,)

The hot and humid weather can make people feel depressed, with no place to release their emotions, and the body will also feel very uncomfortable in the high temperature environment outside. In addition, the daytime hours are longer in summer, and the continued increase in heat and humidity prolongs people's mental excitement period, causing the brain to feel more tired and the ability to manage emotions to be weaker.

"Su Wen" records: The heart is the root of life and the source of spirit. Its brilliance is on the face and its fullness is in the blood vessels. It is the sun among the yang and is connected to the summer energy. The heart corresponds to summer, and health preservation in summer focuses on nourishing the heart.

1. Take a nap to nourish your heart

In summer, the days are long and the nights are short. We should follow nature and go to bed late and get up early, and take a nap for 30 minutes at a time. Remember to cover yourself with a thin blanket or jacket when taking a nap to avoid catching a cold in an air-conditioned environment.

Taking a nap is not only helpful in making up for sleep, making people more energetic, and improving work and study efficiency, but also can improve coronary blood supply, enhance physical strength, and eliminate fatigue. It can also greatly reduce the chances of coronary heart disease, angina pectoris and myocardial infarction.

2. Eating melon nourishes the heart
