Sports that are not suitable for people with high blood pressure

　　The most common misconception is that the greater the intensity and volume of exercise, the better the health benefits. While competitive sports like the 100-meter sprint and weightlifting, which involve short bursts of intense activity requiring explosive power, are anaerobic exercises that constantly challenge and push the limits of human strength and speed, they are not necessarily good for health. In fact, they significantly increase the risk of injury. For the elderly, those with poor physical condition, or those with cardiovascular disease, these activities can easily trigger illness or even accidents.

　　If people with high blood pressure engage in these types of exercise, it will undoubtedly lead to a sharp rise in blood pressure, and may even result in serious consequences such as cerebral hemorrhage. Excessive or strenuous exercise is also detrimental to weight loss, because the key to reducing body fat lies in the duration of exercise, not its intensity. If you are too impatient and try to make up for years of inactivity immediately, the result will be exhaustion within a few days, leading to giving up halfway.

　　Please remember: Rome wasn't built in a day, and the decline in physical fitness caused by lack of exercise happens gradually, requiring time to reverse. The key is persistence, not speed.

　　Misconception 1: Running is a more effective form of exercise than walking.

　　Brisk walking is the simplest and most economical way to improve your health; it's like saving up for the future. Of course, jogging is also a great exercise, but it's important to note that compared to brisk walking, it may cause joint and ligament damage.

　　In his book "Walk! Don't Run," American medical doctor Dr. Staman points out that walking is a safer way to lose weight than running. A US study of middle-aged and elderly women found that six months of running resulted in 40% of them suffering spinal, knee, and ankle injuries—a truly counterproductive outcome. Statistics show that the average person walks 6,500 steps a day; with each step, the impact on the soles of the feet is about 1 to 2 times the body weight, while running increases this to about 3 times.

　　Brisk walking is not only an aerobic exercise that builds endurance, but it's also safer and more effective than running, which is shaking running's position as the king of aerobic exercises. To effectively perform brisk walking, it's best to pay attention to three points: first, walk 3-5 times per week; second, each session should last 20-30 minutes; and third, each session should cover a considerable distance (5-8 kilometers) at a brisk pace. Only in this way can you achieve your fitness goals.

　　Misconception 2: You shouldn't drink water while exercising.

　　About 10 years ago, people believed that one should not drink water during exercise, even during prolonged, high-intensity workouts. Those who held this view believed that drinking water would worsen fatigue and cause gastrointestinal discomfort. Now, we advocate drinking whenever you feel thirsty, because the urge to drink indicates that the body needs water, and when the body is dehydrated, it is easier to experience fatigue during exercise.

　　In addition, insufficient water intake and increased blood concentration can sometimes lead to serious consequences such as cerebrovascular accidents. However, water intake should still be moderate. Generally, drink some water when you feel thirsty while walking. You can replenish some of the water lost through sweating immediately after walking, and the rest should be replenished one or two hours later. Do not drink large amounts of water at once, otherwise you will easily feel tired and increase the burden on your gastrointestinal tract. It must be remembered that if the human body loses 5% of its water, the danger is already very high.

　　Misconception 3: Morning exercise is better than evening exercise

　　In fact, blood pressure is higher in the morning, blood clotting is stronger, and the risk of thrombosis is correspondingly increased, making it a peak time for heart attacks. For the elderly and cardiovascular patients, the ideal time for aerobic exercise is in the evening. Of course, it is not advisable to do too much exercise before dinner or before going to bed, otherwise, excessive excitement will affect sleep.

　　However, morning exercise is more ideal for obese people because the energy required by the body during morning exercise is provided by the oxidation of accumulated fat.

　　Misconception 4: Physical exercise requires overcoming various physical discomforts and pains; only through pain can it be effective.

　　This is a very dangerous misconception. If you experience dizziness, chest tightness, chest pain, shortness of breath, or excessive fatigue during exercise, you should stop exercising immediately and seek medical attention if necessary, especially if you are elderly. It is important to reinforce the idea that you should go to the hospital for chest pain.

　　Myth 5: Applying slimming cream means you don't need to exercise.

　　Many weight-loss pills and creams claim to help you lose weight without dieting or exercise. This is far from the truth. One person, lured by deceptive advertising, bought a weight-loss cream that claimed to break down fat with simple application, showing results quickly without dieting or exercise. However, after using it for a while, they found it ineffective. When they confronted the seller, they were told, "Your body is different from others; if you want to see results, you need to exercise." Later, this person persisted with aerobic exercise and controlled their diet, and their weight quickly decreased.
