Why do some people faint when taking a bath in the bathhouse?

Some people often feel flustered, dizzy and weak when taking a bath. In severe cases, it will fall in the bath hall and cause trauma. This is because the bathroom is an anoxic environment, and people who are old, weak or overtired are particularly sensitive to the anoxic environment. Moreover, the temperature in the bathroom is high, and some people like to soak in hot water for a long time, which is easy to cause vasodilation of limbs and body surface, resulting in transient ischemia and hypotension in the brain. This phenomenon is also called "halo pool". The specific reasons are: for example, weak body, easy to faint suddenly when taking a bath. But a healthy body doesn't do that. Fainting in the shower is actually caused by many reasons. Let's talk about it below.

First of all, in the bathroom, people enter the hot environment from the cold environment. In order to adjust the balance of heat production and heat dissipation, capillaries expand reflexively, and the blood flow of body organs decreases accordingly. In order to ensure the blood supply of brain, heart, kidney and other important organs, the heartbeat will accelerate reflexively, and people will feel heartbeat and palpitation. If this compensation still can't meet the needs of organ metabolism, you will feel dizzy, flustered and short of breath.

Secondly, there is too much steam in the bathroom and the humidity is high. When people take a bath for a long time, they will lack oxygen, tissues and organs will not get enough oxygen, metabolic function will be disordered, and dizziness will occur.

Thirdly, due to lack of oxygen, a large number of acidic substances such as carbon dioxide are produced during metabolism in the body. Stimulate the nerve center to deepen and accelerate the reflex of respiratory movement, resulting in shortness of breath.

Finally, it may also be caused by not eating for a few hours before taking a shower and low blood sugar.

First aid measures for fainting in the bath;

Don't panic, leave the bathroom at once. You can't walk at this time to avoid further aggravation of brain hypoxia.

Pay attention to keep warm after leaving the bathroom, let the patient lie flat, or raise his head slightly 15 ~ 20, feed some hot tea (or sugar water) and recover slowly.

If the situation is serious, you should also relax and rest, take a supine position, and it is best to put books and clothes on your legs that you can get around. When it is a little better, open the window for ventilation.

Wipe your body with a dry towel, from your face to your toes, then put on your clothes and lean your head against the window, and you will recover.
