What are the harms of smoking after a meal

Many people have the habit of smoking. There is definitely no restriction on the choice of smoking time. They can smoke whenever they want. As the saying goes, a cigarette after a meal makes you feel as happy as a god. I believe many people have experienced this comfortable feeling. In fact, the habit of smoking after meals is quite bad and has many effects on our body. So, what are the harms of smoking after a meal? Let’s take a closer look below.

From clinical medicine, we know that after a person eats, the digestive system immediately starts to move in an all-round way, carrying out various physiological activities such as digestion and absorption. At this time, the gastrointestinal motility in the human body is very frequent, blood circulation is accelerated, and the pores all over the body are opened; at the same time, some excess heat energy is released and the biological respiration of tissue cells is intensified.

At this time, smoking will greatly increase the ability of the lungs and body tissues to absorb smoke, causing the harmful substances in the smoke to have a great irritating effect on the respiratory and digestive tracts. It will also allow a large amount of other bioalkaloids to enter the human body, causing much greater damage to human functions and tissues than normal smoking.

These 5 times smoking is most harmful

1. Don’t smoke after meals

After a person has eaten, the digestive system enters a state of comprehensive digestion and absorption. At this time, gastrointestinal motility is frequent, blood circulation speeds up, pores throughout the body open, and some excess heat energy is discharged and tissue cell respiration is accelerated. If you smoke at this time, the harmful substances in the smoke will be absorbed by the lungs and body tissues in large quantities, causing much greater damage to human functions and tissues than normal smoking. Smoking after meals can also cause excessive bile secretion, inhibiting the secretion of trypsin and carbonate, and affecting the digestion and absorption of food.

2. Don’t smoke when drinking coffee

If you smoke while drinking coffee, the harm of using these two types of consumer products together will not only be doubled, but they can react with each other and have a long-term destructive effect on the human body's blood supply system. It can cause temporary hardening of the aorta and damage the body's blood supply system. It will increase the workload of the heart and increase blood pressure to ensure the body's blood supply. If this continues for a long time, it can easily cause sudden heart attack and stroke. Therefore, do not smoke while drinking coffee to reduce the combined harm of tobacco and caffeine to your body.

3. Don’t smoke when drinking

Drinking and smoking at the same time have a synergistic effect on the body, and both can enhance the toxicity of the other. After the carcinogens in the smoke are inhaled into the mouth, nose, throat, trachea and lungs, they are deposited on the surface of the above organs in the form of tar. When drinking alcohol while smoking, the tar adhering to the mouth and throat will go down with the alcohol. The nicotine and tar in the smoke dissolve in alcohol and can be quickly absorbed into the blood and spread throughout the body. Smoking while drinking alcohol will result in a higher level of nicotine in the blood than simply smoking, and is more harmful. In addition, tobacco poison also has the effect of affecting the liver and failing to metabolize alcohol in the body in a timely manner, thus causing alcohol poisoning. Therefore, avoid smoking when drinking.

4. Don’t smoke when you stay up late

Nighttime is the time when cells divide most actively. Poor sleep and prolonged staying up late reduce the body's resistance, making it very difficult for the body to control cell mutations and turn them into cancer cells. Cigarettes contain at least 69 carcinogens, which can cause normal cells to become cancerous and increase the chances of more than 20 types of cancer. Staying up late puts people's physiology in a state of stress. When staying up late, the secretion of adrenaline increases significantly compared to people with punctual schedules. At this time, smoking will quickly produce harmful substances, which will harm the cardiovascular system, increase blood pressure, increase heart rate, and accelerate arteriosclerosis. So if you have to stay up late, avoid sitting for long periods of time, exercise appropriately, take short naps during work, and try not to stay up all night. "Experienced" smokers should smoke as little as possible.

5. Don’t smoke when you wake up in the morning

After a night's rest, the metabolic capacity of most tissues and organs of the body is relatively low, the breathing frequency is relatively slow, and more CO2 is retained in the body. Also, because the air in the room has not circulated and is very dirty after a night, the smoke mixed with cigarette smoke is re-inhaled into the lungs, causing symptoms such as shortness of breath, dizziness, and weakness. In addition, nicotine and other toxic substances in smoke irritate the bronchi, which over time can cause respiratory diseases such as chronic bronchitis. There is a proverb: "If you smoke in the morning, you will die early", which has sounded a wake-up call for people. Although it may sound a bit exaggerated, it can to a certain extent illustrate the harmfulness and seriousness of smoking in the morning.
