Sudden death from staying up late, sudden death from drinking, sudden death from exercise …… This is not alarmist, we have heard of these situations, after all, all kinds of news have been reported, these are only more serious, but in real life, there are many people may not have reached the level of sudden death, just some symptoms, which is actually a warning of heart damage. Downtown cycling Whether driving, cycling or walking to work, as long as you pass through a dense road of vehicles, will increase the risk of heart attack, mainly because of air pollution, of which cyclists to work the most dangerous. Because these people inhale the most exhaust fumes and are the most “polluted”, they also have to strain their nerves to prevent accidents, which can easily lead to insufficient blood supply. Congested traffic is easy to make people nervous, anxious, but also prone to increased blood pressure. The sudden movements such as having difficulty defecating or carrying a bucket of water can cause a sudden surge in blood pressure from a static position, and the pressure on the heart can increase dramatically. When the blood pressure is unstable, the mobility of the vascular plaque increases and it is easy to fall off. Heavy drinking of alcohol or coffee Alcohol and coffee can make the heart rate increase and blood pressure rise, which is the trigger that pulls the trigger for a heart attack. In the case of chronic alcoholics, this can damage the heart muscle and lead to heart failure over time. Depressed moods Bad moods are the worst enemy of cardiovascular disease. Depression usually goes hand in hand with anxiety and can lead to poor quality sleep at night, while the heart does not get rest, making blood pressure and heart rate rise, which is very bad for heart health. Overeating After a person overeats, the gastrointestinal tract needs a lot of blood to digest food, and the blood flowing into the heart and brain vessels is greatly reduced, for people who already have insufficient blood supply to the blood vessels, a full meal can easily induce a heart attack, cerebral infarction. Smoking or passive smoking Although few people suddenly die of sudden cardiac death because of smoking a cigarette, but the damage to the heart of smoking is long-term and stubborn. Long-term smokers have more than three times the risk of myocardial infarction than the average person. Sedentary sitting is not a pleasure. Long-term sedentary and head-down workers can also cause degenerative changes and chronic strain injuries in the cervicothoracic spine, which can compress nerves and lead to nerve disorders that cause continuous spasmodic contraction of the arteries, causing dizziness, neck and back pain, upper limb weakness, numbness of the fingers, lower limb weakness, chest pain and tightness, myocardial ischemia, and even nausea, vomiting, and even blurred vision, tachycardia and difficulty in swallowing, etc. Therefore, if we want to stay away from these heart “killers”, we need to be able to: establish a healthy lifestyle habits and avoid behaviors that are harmful to health.
