In the hot summer, everyone is thinking about how to escape the heat and cool down, but for those elderly people with a history of heart disease, there is also one thing to note: certain exercises may increase the burden on the heart.
Especially patients with myocardial infarction, in this weather, need to be more cautious.
Let's talk about the sports that should be avoided in hot weather and why these activities pose a greater threat to patients.
Let's assume that there is a middle-aged designer who unfortunately suffers from a myocardial infarction because he sits in front of the computer for a long time and is tired from work.

He loves life and wants to maintain his health through exercise, but he may not know that some sports, which are done in hot weather, can actually be a challenge to his heart.
The first exercise that this group of people especially needs to avoid is running for a long time, although running is a good aerobic exercise, in a high temperature environment, it can greatly increase the burden on the heart, especially for people who already have a diseased heart.
Sports such as basketball or soccer that require instantaneous explosive power are also not suitable, imagine that in the scorching heat, a person with an unhealthy heart runs and jumps on a basketball or football field, which is a great test for the heart.
Even healthy people can feel uncomfortable in hot weather due to an imbalance in thermoregulation, let alone those with special heart needs.
In addition to this, there are also activities that seem easy but are actually more taxing on the heart, such as hiking.
In hot weather, climbing causes the heart to beat faster to maintain body temperature and meet muscle demand, which is a challenge for people with myocardial infarction.
While the beauty of nature can bring comfort to the soul, it is wiser for people with heart attacks to choose cool weather or a gentle route.
Why are these sports especially dangerous in hot weather? Hot weather causes the body's internal heat regulation mechanisms to overwork, and the heart needs to pump more blood to the surface of the body to help dissipate heat.
If you exercise at high intensity or for long periods of time, the pressure on your heart increases, especially in people whose heart function is already impaired, and can lead to a heart attack or other serious heart problems.
When a heat wave hits, people with myocardial infarction should choose low-intensity, low-risk exercise, such as walking or short bursts of activity in the water, to stay active without over-stimulating the heart.
By arranging the type and intensity of exercise, you can effectively protect your heart health and enjoy life even in the hot summer.
Hot weather is undoubtedly a huge challenge for patients with myocardial infarction.
Everyone knows that high temperatures put the heart under more stress, but few people think about the specific physiological effects of heat on heart patients and how to take more effective protection measures in such extreme weather.
The direct effect of high temperature on the heart is mainly achieved by changing the hemodynamics in the body, in a hot environment, in order to dissipate heat, the blood vessels in the body will dilate, and the blood flow to the surface of the body, so that the body heat can be dissipated through the evaporation of the skin surface.
However, vasodilation means that the heart needs more blood to maintain blood pressure, which can undoubtedly increase the burden on the heart for people who already have heart problems.
Imagine an elderly person whose heart is no longer strong enough and tries to do outdoor activities on a hot summer day, and his heart needs to work harder under this high temperature pressure to maintain normal circulation and blood pressure, which can easily trigger cardiac events.
In addition, hot weather can also cause the body to lose water quickly, and this dehydration state can further increase the viscosity of the blood, making it more difficult for the heart to pump blood with high viscosity, increasing the risk of blood clots.
This is why examples of heart attacks are more common in hot weather. In continuous hot weather, the number of patients with acute heart attacks increases significantly, and the physiological mechanism behind this is the change of blood viscosity and the increase of the burden on the heart.
High temperatures can also affect the effectiveness of medications in heart patients, and some heart medications, such as diuretics, can inherently promote the excretion of water from the body, further exacerbating dehydration.
And in a hot environment, if you don't increase your water intake properly, the side effects caused by this drug can be more severe. Therefore, patients with heart disease need to pay special attention to the use of drugs and hydration in hot weather.
For some people with heart disease who need regular physical activity, switching to water activities, such as swimming or water fitness, is recommended to maintain physical activity and avoid excessive exposure to heat.
Because of the buoyancy and heat dissipation effect of water, water activities have less pressure on the heart and are more suitable for people with cardiac insufficiency.
People with heart disease need to pay special attention to their physical condition in the summer, and if they feel unwell, such as chest pain, shortness of breath, extreme fatigue or dehydration, they should immediately stop all activities and seek medical help.
Health always comes first, and we must use scientific methods to deal with the challenges brought by high temperatures to the heart, minimize unnecessary risks, and let every heart disease patient get through this summer safely.
Choosing the right exercise is crucial for people with a heart attack, but there are many other things that can help prevent a heart attack in addition to exercise, especially during the hot summer months.
Maintaining proper water intake is also crucial, as people sweat easily in hot weather, which can quickly lead to the loss of water and electrolytes in the body, which can increase the burden on the heart.
People with a heart attack should make sure they drink enough water, but avoid drinking too much water, as this can lead to dilution of sodium in the body, which can increase the burden on the heart.
An easy way to do this is to observe the color of your urine and keep it yellowish, which is often a sign of a good hydration status.
The quality of sleep is essential for health, and sleep deprivation is strongly associated with the risk of heart disease.
Adults should strive to ensure that they get at least 7 hours of quality sleep each night. For people with a heart attack, regular sleep patterns can help regulate the body's stress hormones, such as cortisol, which is important for maintaining heart health.
Some people may find it difficult to fall asleep due to the summer heat, so try some tips to help you sleep, such as using an air conditioner or fan to adjust the indoor temperature, or doing light relaxation activities before bed.
While proper exercise is key to preventing a heart attack, a holistic approach to lifestyle modification is equally important. Through a scientific diet, moderate water intake, high-quality sleep, and effective stress management, heart health can be guaranteed on a broader level.
