What happened to the man who insisted on taking cold showers? 5 moments are not recommended to take a bath, or hurt the body
After working overtime, Xiao Li was planning to take a shower before going to bed, only to find that the gas bottle was empty. Thinking it would be troublesome to change the gas, he might as well take a cold shower.
Before that, I heard that taking a cold shower for a man can improve immunity and make the body stronger , so he did what he said, and Xiao Li took a cold shower directly.
Although he felt a headache in the shower, Xiao Li didn't pay much attention to it. After taking a cold shower, Xiao Li found that his body was hot and his head hurt more and more.
Not long after, a sense of powerlessness struck, and one side of his body seemed to start to lose control, and when he sensed something was wrong, he called his companions to take him to the hospital.
When he arrived at the hospital, Xiao Li's face turned pale and his body was stiff, and he even began to lose consciousness. His condition was critical! The doctor said that Xiao Li bathed in cold water, and the temperature difference was huge, and the blood vessels in his brain constricted and spasmed , which led to a stroke.
1. Taking a cold bath in summer is more likely to cause sudden death?
Previously, many news reports have reported related news such as "take a cold shower in summer, and die of a sudden myocardial infarction". However, the weather is hot in summer, and many people will choose to take a cold shower. Isn't this very dangerous?
Many people choose to take cold showers in summer to cool down, but do cold showers really cool down?
In fact, cold water can quickly take away heat from the body surface, but after a sudden drop in temperature, the body will also increase heat production to cope with the stimulation of cold water, and cold water will stimulate the skin to cause vasoconstriction, hindering the body from dissipating heat .
In other words, the cooling effect of taking a cold bath in summer is temporary, but it will increase the body's heat production. From this point of view, taking a cold bath is not as cooling as taking a warm bath.
In the sudden death incident caused by taking a cold bath in summer, the cold bath can only be regarded as the predisposing factor, and the root cause is still the disease. For example, when a patient with angina pectoris takes a cold bath, the cold will stimulate arterial spasm and interrupt the blood supply to the myocardium, which may cause arrhythmia, myocardial infarction, and sudden death.
In addition, people who have already caught a cold and those who suffer from cardiovascular and cerebrovascular diseases are best not to take a cold bath.
It should be noted that, in fact, for people with severe coronary artery stenosis but mild symptoms, taking a hot bath for a long time also has a risk of sudden death. Because your body temperature rises when you take a hot bath. It is also prone to malignant ventricular arrhythmias, namely Brugada syndrome.
2. Is a man taking a cold shower "healthy" or hurting his body?
Many people may have heard that "taking cold showers can strengthen the body", and also said that "frequent cold showers can enhance resistance". Is there any scientific basis for this?
In fact, taking a cold bath is indeed a way to exercise the body. The temperature difference generated by the cold bath can stimulate the body's temperature regulation system, and at the same time enhance the function of blood vessels and nerves.
Therefore, taking a cold shower can serve the purpose of exercising to some extent. However, compared with taking a cold bath, taking a hot bath is also very warm and comfortable. So in daily life, what is the best temperature for taking a bath?
A study published in the "Review of Sleep Medicine" reviewed and analyzed 5322 research reports related to bathing and sleep, and finally found that: five hours or more before going to bed, using water at two temperatures of 41°C and 35.5°C When taking a bath, the water temperature of 41°C will increase sleepiness before going to bed, but 35.5°C will not .
The researchers further found that the body temperature of a person is not constant throughout the day. It is higher in the morning and evening and lower in sleep at night. If one wants to get a good sleep, the body temperature must be lowered before going to bed. Taking a hot bath before going to bed will release the core heat of the body to the body surface and the environment, thereby achieving cooling.
In other words, taking a warm bath one to two hours before bed can change the circadian clock and help you fall asleep faster .
3. It is not recommended to take a bath at these 5 moments, or it may be harmful
Many people think that bathing is the most common thing in life. It is simple and time-consuming, and it can be done in three to five minutes. In fact, bathing is really particular, especially the five moments, don't take a bath!
1. When sweating profusely
When sweating, the pores on the skin surface are dilated. Bathing in cold water may be temporarily comfortable, but it will stimulate the pores and constrict the blood vessels. This will undoubtedly stimulate the cardiovascular system, especially for people with cardiovascular and cerebrovascular diseases, and sudden death risks of.
2. After drinking
Alcohol can cause blood vessels to dilate and cause blood pressure to drop. If you take a bath at this time, warm water will stimulate blood vessels to expand further, and blood pressure will drop again, which can easily cause hypotension. Risk of fainting.
3. When you are full/hungry
Take a bath after eating a full meal. Warm water will stimulate blood vessels to dilate, and blood will also accelerate to the body surface. At this time, the blood flowing to the abdominal cavity will decrease, and the digestion and absorption capacity will become weaker, which will cause hypoglycemia and even make people feel sick. collapse, pass out.
It is not advisable to take a bath when you are hungry, as it will also cause hypoglycemia symptoms such as dizziness, sweating, and weakness.
4. When sick
It is not recommended to take a bath when you are sick and have a fever, especially when the body temperature is 38°C, the body heat consumption will increase by 20%, and the body is very weak, and bathing at this time is prone to danger.
5. After physical labor
After physical or mental work, it is best to take a short break before taking a bath, otherwise it is easy to cause heart and brain ischemia, which may lead to fainting.
Many people may choose to take a cold bath directly because of the hot weather or because they are lazy. If a healthy person takes a cold bath, it is not a big problem, but if there are underlying cardiovascular and cerebrovascular diseases, the risk of sudden death in a cold bath starts to increase.
