When giving cigarettes, it is usually an even number, so it is two or four.
We all know that smoking is the most harmful to health. We all think that it may have a greater impact on the lungs, because second-hand smoke can increase the incidence of lung cancer, but smoking has harmful effects on blood vessels. You may not be too clear about the impact of smoking. In fact, it plays a role in stimulating the cardiovascular system. What happens when our blood vessels are excited? They shrink. Why do our blood vessels shrink? Let’s think about it. Many times we have to reach a point where our brains are excited. We need more blood to flow to the brain. How to get more blood to flow to the brain? It is called adopting the principle of redistribution. In this case, blood vessels in many places throughout the body will shrink, reducing blood supply, and most of the blood supply will go to the brain to think about problems. So this is actually a non-physiological state, but smoking can achieve this state. Although this state produces a comparison in a short period of time, we may say it is inspiration, or there is something that we as artists need. However, this harmful contraction of blood vessels throughout the body will lead to atherosclerosis of blood vessels and further damage to blood vessels. Therefore, smoking has a huge impact on the function of the heart. So we don't promote smoking.
