Don’t watch TV for long periods while drinking strong tea
Making a cup of strong tea and sitting in front of the TV all day is a lifestyle for many. Watching TV for one hour can increase the risk of cardiac death by 7%, and for four hours, the risk rises to 28%. Adding strongly stimulating beverages such as strong tea, coffee, or alcohol can accelerate your heart rate and put additional strain on your heart. Limit TV watching to 1–2 hours per day and take breaks. It’s best not to drink overly strong tea to avoid overstimulating the heart.
Avoid saunas after excessive fatigue
Taking a sauna when feeling extremely tired is a leisure activity many enjoy. However, the excessively high temperatures in a sauna cause rapid dilation of subcutaneous blood vessels, increasing the burden on the heart. Elderly people and those with heart disease or hypertension should avoid saunas. If you experience discomfort such as nausea, palpitations, or a rapid heartbeat, stop immediately.
Don’t smoke in chess and card rooms
Cigarette smoke contains toxic substances like nicotine, which are risk factors for causing vascular spasms, myocardial ischemia, severe arrhythmia, and even sudden death. People playing cards often smoke constantly, and most chess and card rooms have poor ventilation. Especially for those with high blood pressure or weakened health, prolonged exposure in such environments can lead to illness or even sudden death.
Avoid jumping out of bed abruptly in the morning
The hours from 6 a.m. to 11 a.m. are referred to as the “devil’s time” for cardiovascular and cerebrovascular diseases. The walls of the heart and blood vessels are at their most fragile in the early morning, and 70%–80% of sudden cardiovascular events occur during this period. When you first wake up, your heart rate speeds up from slow to fast, making it easier to develop blood clots. Getting up abruptly can cause a sudden rise in blood pressure that the body can't handle, leading to symptoms of orthostatic hypotension such as dizziness, nausea, and weakness in the limbs. This is especially risky for people with hypertension, coronary heart disease, arteriosclerosis, or narrowed blood vessels, as sudden movement can easily trigger accidents.
Rise slowly after using the squat toilet
Studies show that straining during bowel movements can cause intense contractions of the abdominal and diaphragmatic muscles, leading to a drop in blood pressure that may result in cerebral hemorrhage. Increased myocardial oxygen consumption may also induce angina or myocardial infarction, both of which can cause sudden death. If you’ve spent a long time on the toilet and stand up too quickly afterward, you may experience transient cerebral ischemia due to a sudden change in posture, leading to dizziness, blurred vision, falls, or even cerebrovascular incidents. Therefore, it’s important to rise slowly.
Don’t open the car window when stuck in traffic
After being stuck in traffic for an hour, the risk of a heart attack increases by 3.2 times. The high stress of driving accelerates the heart rate and causes myocardial fatigue, which can easily trigger coronary heart disease. Opening the window allows dirty air along with a host of pollutants to rush in. This not only harms the heart but also affects the lungs. So, when encountering traffic congestion, it's best not to open the window for ventilation—using the vehicle’s internal air circulation system is advisable.
Don’t take a cold shower after exercising
After an intense workout that leaves you drenched in sweat, taking a cold shower might feel incredibly refreshing. But this is also when your heart is at its most vulnerable. Sudden exposure to cold water causes blood vessels throughout the body to contract sharply, increasing blood pressure and the workload on your heart and lungs. This can lead to discomfort such as palpitations, shortness of breath, and dizziness. Therefore, avoid taking a cold shower immediately after sweating from exercise.
