Why can't you smoke in bed?

Because you smoke in bed, if you are not careful, cigarette butts will be painted on the bedding. Article 14 of the "Twenty Common Sense of Fire Safety" stipulates: Don't smoke on the bed and sofa, and don't throw cigarette butts.

When there is a fire, especially after fatigue or drunkenness, people often fall asleep before smoking, causing cigarette butts to burn combustibles such as bedding and mosquito nets.

The temperature of the lit cigarette can reach 700℃, and the continuous burning time of a cigarette is about 15 minutes. However, the spontaneous combustion points of common combustibles such as paper, cotton, hemp and its fabrics are very low, and their ignition points are mostly between 200℃ and 300℃, while the ignition point of cigarettes is 2~3 times higher than these solid combustibles.

Therefore, unlit cigarette butts are enough to cause fires of solid combustibles, flammable liquids and gases.

Hazards of smoking:

1, endangering lung health

Smoke will be produced when smoking. It can be said that smoke contains many harmful substances, such as carbon monoxide, nicotine and tar. When smoking, these toxins will enter the lungs with the smoke, and the long-term accumulation of these toxins will increase, causing the disorder of lung self-regulation, making the lungs unable to carry out normal physiological activities and forming lung diseases.

2. Induce a stroke

Nicotine inhaled during smoking will promote the release of adrenaline and norepinephrine, cause vasospasm or contraction, and increase the pressure of blood circulation. This long-term change will damage the blood vessel wall and make it more prone to atherosclerosis. Adrenaline secretion increases, blood cholesterol content increases, intercellular space becomes larger, and fat deposits easily lead to arteriosclerosis, and then cerebral thrombosis and stroke occur.

3, induce heart disease

Cigarettes contain a lot of nicotine, which will make our heart beat faster. Carbon monoxide produced by smoking can promote atherosclerosis and easily lead to heart disease.

4, prone to cancer

Nicotine, tar and carbon monoxide contained in cigarettes are highly carcinogenic, which will increase the risk of cancer in men, thus causing cancer and increasing the chance of death.

5, reduce immunity

People who smoke for a long time, the immune system will decline, increasing the possibility of disease invasion, which will lead to heart disease and arteriosclerosis. Smoking can lead to decreased immunity. A nicotine toxin contained in tobacco can damage nerves, and the high content of carbon monoxide in cigarettes can cause hypoxia in the brain, thus damaging the immune system.

6, affect fertility

Nicotine in tobacco will also damage women's ovaries, which will not only lead to abnormal secretion of sex hormones, but also reduce the number of mature oocytes. Long-term smoking will not only affect the health of sperm and eggs, but also inhibit the secretion of sex hormones. Nicotine has the function of killing sperm, resulting in a decrease in the number of sperm, which will greatly reduce the probability of pregnancy, because the egg lacks sperm that binds to it.

7, induced hypertension

Long-term smoking will make blood thick and blood pressure rise. Carbon monoxide produced during smoking will react with oxygen after entering blood vessels, taking away oxygen atoms in the blood and causing hypoxia in the body.

8. Hurt people around you

Second-hand smoke is also harmful. After being absorbed by people around you, the toxic substances will enter the body with the breathing of people around you, causing harm to the inhaler.

9, affect oral health

Smoke contains a lot of volatile sulfides, and a lot of smoking will also form tongue coating, which will make food residues stay, reduce saliva secretion and aggravate bad breath. Frequent smoking can also turn teeth black and yellow, which is difficult to remove by brushing your teeth.

10, wasting money

Smoking is not only harmful to health, but also causes certain difficulties to personal money. In particular, some high-priced cigarettes will still form an economic burden on smokers, which is even worse for those smokers who smoke according to the number of packs every day.
