How to wash in a hot bath?

After a busy day, taking a hot hot shower before going to bed has become the most enjoyable moment for many people every night. But did you know that not all “hot baths” help eliminate fatigue and help sleep.

Bath temperature and method

A study in the well-known sleep medical journal Sleep Medicine Reviews found that taking a warm bath before bedtime can improve the overall quality of sleep. The best water temperature is between 40 and 42.8 ° C. If you take a shower 1 to 2 hours before going to bed, you can also increase the speed of falling asleep by 10 minutes on average.

In cold weather, taking a hot bath can eliminate fatigue and improve sleep. But if the bathing method is not correct, it is not only easy to induce disease, it may even cause accidents.

1. Sudden Cardiovascular and Cerebrovascular Diseases

When the skin is stimulated by hot water, the capillaries will dilate, blood flow will accelerate, and the heart’s reflex heart rate will increase. Once the faucet is turned off, or the cold invades in the bathroom, the capillaries will contract again. Hot and cold changes will continuously stimulate blood pressure and heart rate, and it is easy to cause acute brain and heart ischemia in patients with hypertension, leading to acute stroke, heart disease and other risks.

Suggestion: The bath time should not be too long, preferably about 15 minutes, not more than 20 minutes, in order to avoid the skin vasodilation caused by steaming, insufficient blood supply to the brain, dizziness, chest tightness and other symptoms.

2. Carbon monoxide poisoning

The relatively small area in the bathroom, coupled with the closed doors and windows, the bath time is too long, the oxygen is consumed, and people will suffer from hypoxia or carbon monoxide poisoning.

Recommendation: When using gas water heaters, you must pay attention to maintaining good ventilation, and do not hang objects on the air supply and exhaust ports of the room to avoid affecting air circulation.

3. Eye injury

The baby needs to turn on the bath heater when bathing, but it must be used with care. The light from Yuba belongs to the strong light, and the baby stares for a long time, which is prone to macular degeneration.

Suggestion: Try to choose air-heated Yuba. Parents can use their bodies to block Yuba’s light and prevent their babies from looking directly.

4. Electric leakage

Electric water heaters, hair dryers, electric wire heaters, and oil heaters used in the bathroom all use power. However, there are many water sources in the bathroom, which can easily cause leakage and electric shock.

Recommendation: If you use a heater in the bath, be sure to put it away from bathtubs, showers, and bathtubs. It is recommended to set the plug outside the bathroom. If it is a socket in the bathroom, it must have a waterproof cover.

The correct “posture” for bathing

1. Keep warm in advance

It is best to do warm-up exercises for 5 minutes before bathing, such as stepping on the spot, twisting the waist, rubbing feet, massaging Yongquan points, etc. Turn on Yuba five minutes in advance to ensure the bathroom is warm.

2. Pay attention to the order of bathing

When taking a hot bath, warm water suddenly comes from the head, causing a large amount of blood to concentrate on the surface of the skin with dilated blood vessels, causing heart and brain ischemia, dizziness, chest tightness and other discomfort. People who already have cardiovascular and cerebrovascular diseases may also cause angina and other diseases.

It’s best to flush your feet with hot water before taking a bath. After your feet are warm, slowly pour water on other parts of the body to allow the body to gradually adapt.

3. Replenish water before and after bathing

Drinking a glass of boiled water before bathing can supplement the large amount of water lost due to the expansion of capillaries; you should also drink some water after bathing, but it is not advisable to drink in large amounts to avoid increasing the burden on the heart.

Three hours is not suitable for bathing

After drinking: After drinking, the blood glucose concentration drops, and taking a bath immediately may cause hypoglycemia symptoms or even shock. Bathing should be at least 2 hours after drinking.

After high-intensity exercise: High-intensity exercise accelerates blood circulation. Taking a bath immediately will continue to increase blood flow in the skin, increase body fatigue, and may also cause insufficient blood supply to the heart and brain. It is recommended to wait at least 20 minutes before the end of the exercise before taking a bath.

After cupping: After cupping, the skin is in a state of being “injured” and sensitive and fragile. At this time, taking a bath can easily cause skin damage and inflammation. It is recommended to wait for two or three hours.

Since the outbreak of the New Coronary Pneumonia epidemic, Germany was initially referred to as the “superior” of European anti-epidemic disease-relatively few cases of infection, and the mortality rate is controlled below 1%. However, the German epidemic has grown rapidly since the beginning of March. By April 7, the number of diagnoses in Germany had exceeded 100,000, making it the third-largest infected country in the EU and the world. Germany has shown its advantages in the fight against the epidemic, and it also highlights some common problems in European countries.

The rapid growth of the German epidemic situation has both objective reasons and subjective factors. Objectively speaking, the new coronavirus is extremely contagious, there are many characteristics and uncertainties, and it is extremely difficult to prevent epidemics. Unlike Asia and the United States, EU member states have many limitations in terms of epidemic prevention:

First of all, under the background that European integration has been advancing for many years, there are many practical difficulties in carrying out effective border and personnel flow control. Secondly, in the face of such a fierce large-scale infection, the EU public health emergency system cannot effectively respond: the EU has limited power, only the power of advice and coordination, and the unified command and coordination required to respond to the spread of the European epidemic is far from enough; In the early stage of the outbreak, each country acted independently, protected itself first, and even blocked and intercepted materials. Under the EU framework, the sovereignty of each country was no longer complete, and its comprehensive capabilities, including its ability to prevent epidemics, were greatly restricted. These factors have a certain impact on the prevention and control of the German epidemic.

From the main point of view, Germany is the earliest country in Europe in terms of anti-epidemic preparations. On January 6, Germany established a monitoring committee, and later began to increase the storage of medical supplies such as ventilators. However, since then, European countries, including Germany, based on the experience of SARS, regarded it more as an epidemic situation in China, but only adopted general epidemic prevention, and the preparation was obviously insufficient. After the outbreak in Italy in late February, German epidemic prevention experts had deviations in the characteristics of the new coronavirus and epidemic prevention recommendations, and did not provide the federal government with effective recommendations to suppress the rapid spread of the epidemic. Prime Minister Merkel was influenced by medical experts’ opinions similar to “group immunization”, suggesting that 60% to 70% of the German people may be infected with the new coronavirus.

At the policy level, the German government has also considered too much the balance between isolation and freedom, economy and epidemic prevention, central and local, and different interest groups. Too much trust in its own experts and health system has prevented the strength, intensity and speed of epidemic prevention Suppress the rapid development of the epidemic.

On March 18, Germany confirmed more than 10,000 cases, and the government’s stance on preventing and controlling the epidemic situation became tougher. Merkel delivered a speech, emphasizing that the epidemic situation has become the biggest challenge facing Germany after World War II. From March 23, in principle, two or more persons are prohibited from gathering in public places; it is recommended that the public minimize contact with people outside the family members; the public is required to maintain a distance of at least 1.5 meters from others in public places; Meetings are held in private places. Shops such as hair salons and massage shops that have close physical contact must be closed and so on. These measures are close to isolation, the purpose is to reduce personnel contact and delay the spread of the epidemic. All walks of life in Germany have also taken action. The President called for national unity to fight against the epidemic. The Parliament passed the Infection Protection Act. The army sent 15,000 soldiers to support the fight against the epidemic. The government passed a total aid package of up to 756 billion euros to support vaccine development , Increasing medical measures, supporting enterprises, and helping the unemployed. Germany has also intensified cooperation with the EU and its member states and strengthened international cooperation.

A series of measures taken by Germany will undoubtedly help curb the epidemic. At present, the development of the German epidemic has three characteristics: rapid growth rate, high case base and low mortality rate.

The fast speed is related to the lack of early and mid-term epidemic prevention measures. If the restrictive measures are implemented in place after March 23, the speed should be delayed. The high base is linked to Germany’s strong quarantine capacity. Germany has the strongest quarantine capacity in Europe, with a quarantine capacity of up to 350,000 person-times per week. The inspection capacity can be increased to 200,000 per day by the end of April. The low mortality rate is related to Germany’s strong quarantine ability, good medical conditions, and relatively young patients. Germany has the best medical resources in Europe, including 28,000 intensive care beds, far better than other European countries.

On the other hand, it should also be noted that the number of confirmed cases in Germany is currently very large. Against the background of the rapid spread of the epidemic in the world, and in an environment in which neighboring countries in Europe are not spared, effectively suppressing the epidemic is still a difficult task. If the number of confirmed cases continues to rise sharply, there will be a shortage of medical resources and the mortality rate will increase relatively. Therefore, the German epidemic prevention must not be taken lightly, strengthening isolation, early detection and early treatment is a top priority. It is also important to fill in the shortcomings, including taking further effective isolation measures, strictly enforcing laws, strengthening the recommendations for wearing masks, and accelerating the development of vaccines and drugs.

The epidemic is a challenge to all mankind, and strengthening international cooperation is very important for every country. After the outbreak, China and Germany not only helped each other but also cooperated. Experts from China and Germany conducted remote exchanges on the clinical treatment of new coronary pneumonia, research and development of drugs and vaccines, etc. Germany and China donated medical supplies to each other one after another; the scientific research and health institutions of the two countries maintained close contact to promote practical cooperation between the two sides; The two countries have also cooperated well in international organizations such as WHO and G20 to jointly fight against the new coronavirus and practice the concept of a community of destiny.
