Why are my lips white and purple when it s cold?

Due to the low temperature and poor blood circulation, the amount of reduced hemoglobin in the mucous membranes increases, and the lips become purple. Increasing physical activity and improving the body's blood circulation rate will make some changes.

Almost half of our blood is made up of red blood cells, and it is the red blood cells that determine the color of the blood. The main function of hemoglobin in red blood cells is to transport oxygen, bind to oxygen when blood flows through the lungs, and release the bound oxygen when blood flows through other tissues for tissue oxidation. The oxyhemoglobin combined with oxygen is called oxyhemoglobin and is bright red in color; After dissociation with oxygen, it is called reduced hemoglobin, which is dark purple in color.

When in a cold environment, the cold outside will affect the blood in **. Immediately after freezing, the nerve center will direct the vasoconstriction to reduce the heat dissipation from the body. However, if the freezing time is too long, the nerve effect tends to be paralyzed, and the nerve sensation is basically ineffective, but it will cause the expansion of blood vessels, which is called congestion, when the blood flows through the dilated blood vessels, the blood flow speed is greatly slowed down, and a large amount of reduced hemoglobin in the surrounding tissues is accumulated here.

And because the mucous membrane of the lips is thin and transparent, the lips will look blue and purple after people are frozen.

When the ** freezes and turns blue-purple, it means that the freezing time is relatively long, and the breathing of the tissues is impaired, if it continues, this part is blocked due to blood clotting, and there is a possibility of frostbite.

The activity of enzymes decreases, blood circulation weakens.

Physical exercise should be strengthened, physical fitness should be improved, and attention should be paid to a reasonable diet, so that the situation can be well improved.

According to the information you provide, if there are no other uncomfortable symptoms, this situation is normal, the weather is cold, the human body in order to keep the body temperature constant, the peripheral blood vessels constrict, the blood flow is slow, the heat loss is reduced, can play a role in heat preservation, the lips belong to the peripheral blood vessels, this situation is normal, do not be nervous.

It may be that the cold in the body is too heavy, so it is recommended that you regulate your body more and pay attention to sleep.

Purple lips, heart and lung problems can affect the amount of oxygen in the body that passes through the bloodstream. If the amount of oxygen decreases significantly, it is first manifested in the purple lips, and if it occurs after exercise, it should not be a big problem. In addition, if you eat a lot of pickles, it will cause intestinal cyanosis due to the action of nitrite.

Purple lips Caused by poor blood circulation, susceptible to heart disease, anemia, and a tendency to stroke...

Also check if there is a problem with the heart, mainly because of the blood supply to the human body.

Hello, according to your account, this condition is often caused by hypoxia, poor blood circulation.

If the blood circulation is not smooth, strengthen the exercise and run 5000 meters a day.
