Smoking with wound healing

How does smoking affect wound healing?

Cigarettes contain nicotine, which can narrow your arteries and spasm your arteries, causing oxygen and nutrients in the blood to reach your wound, which are essential for wound healing. The inability of the wound to receive enough oxygen and nutrients can cause the wound to not heal.

The effects of smoking on wound healing are multifaceted, mainly including increasing the risk of wound infection; reducing the level of vitamin C necessary for healing; reducing cell proliferation and migration in the wound bed; affecting macrophage activity and affecting the body's defense ability; reducing epithelialization and wound contraction and delaying wound healing; hindering the oxygen supply of wounds; reducing the ability of the human immune system; and reducing the blood supply to the distal (hands/feet) of the body.

What other effects does nicotine have on the body?

· Smoking can cause a number of different cancers;

· Smoking increases heart rate and blood pressure, thereby increasing the burden on the heart and blood vessels;

· May cause a myocardial infarction, stroke, or amputation;

· Smoking creates a tar-like layer of substance in your lungs that can lead to lung cancer;

· Smoking can lead to emphysema and chronic bronchitis, which in turn can lead to lung and heart dysfunction and even failure;

· Smoking can cause damage to almost every organ of the body;

· According to 2019 data from the World Health Organization, in 2018, the number of people killed by tobacco worldwide was 8 million, and 1 person died of smoking every 6 seconds, reducing the average life expectancy of smokers by 10 years. More than 2 million people die from smoking in China each year.
