what wrong way to take a bath will harm your health?
taking a bath before going to bed will cause insomnia
taking a bath before going to bed will inhibit the secretion of melatonin in the brain if the water temperature is too high. It is difficult to go to bed immediately after taking a bath, so taking a bath two hours before going to bed is the most correct way. If you must take a bath before going to bed, Cold compress your forehead with a wet towel for a few minutes after washing your hands.
taking a bath after getting up will be dizzy
many people are used to taking a bath immediately after getting up in the morning, thinking that this can promote the excitement of the brain and ensure the mental state of the day. In fact, taking a bath without breakfast in the morning is prone to hypoglycemic shock. At this time, coupled with the vasodilation caused by too high water temperature, it will also lead to insufficient blood supply and oxygen supply to the brain, which is prone to stroke and other accidents.
bathing immediately after a full meal will affect digestion
bathing immediately after eating too full will affect the digestive function of the intestines and stomach, because just after eating, a large amount of blood will continue outside. At this time, bathing will accelerate the blood circulation of the whole body and expand the blood tubes, which will affect the digestive function of the intestines and stomach. Especially after drinking, you can’t take a bath immediately, otherwise it will easily lead to a drop in blood pressure, weakness, and even stroke and heart disease.
inadequate preparation before bathing is easy to induce cardiovascular and cerebrovascular diseases
now it is almost autumn, so the water temperature of bathing should be kept at a constant temperature, but many people still keep the habit of bathing in summer. Bathing with cold water is a very dangerous thing, especially the elderly, who are prone to discomfort symptoms such as dizziness and dyspnea, Will increase the risk of cardiovascular and cerebrovascular diseases. Therefore, when taking a bath, the elderly should first burn the water to about 45 ℃, and then warm up before taking a bath. Taking a bath is the best state.
Take a bath
taking a bath for too long makes you tired
many people feel very comfortable in the process of taking a bath, because the longer you take a bath, the better your health. In fact, this is a serious misunderstanding, The best time to take a bath is 15 minutes. If you take a bath for too long, you will feel weak all over the body, because the lactic acid concentration in the blood has a great relationship with fatigue. If you take a bath for too long, the lactic acid concentration will return to the level before fatigue. Therefore, do not take a bath for too long.
times per week
in summer, the human body secretes vigorously and perspires more, so it should be washed once a day. The weather in winter, spring and autumn is not hot, and the number of baths can vary from person to person. For those with fat body and strong secretion of sebaceous glands, the number of baths can be appropriately increased. The secretion of sebaceous glands in the elderly is reduced, which can appropriately reduce the number of baths.
how much is the bath water temperature?
the bath water temperature should be close to the body temperature, i.e. 35 ~ 37 ℃. If the water temperature is too high, the systemic epidermal blood vessels will expand, the cardiac and cerebral blood flow will be reduced, and hypoxia will occur. The water temperature when pregnant women take a bath should not be too high to prevent fetal hypoxia and affect fetal development. Take a moderate cold bath in summer. If the bath water is too cold, the skin pores will suddenly close, the blood vessels will suddenly shrink, and the heat in the body will not be released. Especially on hot nights, people often feel weak limbs, shoulder and knee pain and abdominal pain after taking a cold bath. It can even become a predisposing factor of arthritis and chronic gastrointestinal diseases. Generally, the water temperature of cold bath in summer should not be lower than 10 ℃.
suitable time
no matter in spring, summer, autumn and winter, the bathing time should not be too long. Each bathing time should be 15 ~ 30 minutes to prevent heart and brain hypoxia and ischemia.
Unfavorable conditions
do not take a bath after a full meal and when hungry. After taking a bath after a full meal, the epidermal blood vessels of the whole body are stimulated and expanded by hot water, more blood flows to the body surface, and the blood supply to the abdominal cavity is relatively reduced, which will affect digestion and absorption, cause hypoglycemia, even collapse and faint.
do not take a bath after drinking. Alcohol can inhibit liver activity and hinder the recovery of glucose in the body. When bathing, the consumption of glucose in the human body will increase. If you take a bath after drinking, if your blood sugar is not supplemented in time, you are prone to dizziness, dizziness and general weakness. In serious cases, you may also have hypoglycemic coma.
do not take a bath immediately after work. Whether it is physical or mental work, you should rest for a while before taking a bath, otherwise it is easy to cause insufficient blood supply to the heart and brain, and even syncope.
do not take a bath when blood pressure is too low. When the water temperature is too high, people’s blood vessels dilate, and people with hypotension are prone to transient cerebral insufficiency and collapse.
it is not suitable to take a bath when you have a fever
when people’s body temperature rises to 38 ℃, the body’s heat consumption can increase by 20%, and the body is weak. At this time, taking a bath is prone to accidents.
Who should not take a bath
should not take a bath when you have a fever. When the body temperature rises to 38 ℃, the body’s heat consumption can increase by 20%, and the body is weak. Taking a bath at this time is prone to accidents.
in addition, even if there is no high fever, it is best not to take a bath during the acute development of the disease. Patients with severe heart disease, high anemia, uremia, hypertension with a high pressure of more than 180 mm Hg, myocardial infarction, acute nephritis, acute hepatitis and trauma should not take a bath.
who should not take a bath often
patients with cerebrovascular disease should not take a bath often. The thermal stimulation generated during bathing will accelerate the blood flow in patients, and then increase the pressure of blood on blood vessels. When blood flow passes through some local lesions, blood vessel rupture is easy to occur.
epilepsy patients should not take a bath often. When bathing, because a large amount of water vapor is inhaled into the body, the oxygen content in the body decreases. In addition, the sweat discharged by the body increases, and the electrolyte balance is disturbed, which is easy to cause temporary dysfunction and induce epilepsy.
the elderly should not bathe too often. The elderly have weak physical strength, thin skin, gradual atrophy of sebaceous glands, frequent bathing, dry skin and itching. When bathing, the water temperature is too high, and the heat in the body is not easy to dissipate. It is also easy to cause telangiectasia and cerebral ischemia, dizziness and even fainting.
