Healthy people can tolerate a hot summer environment, but according to a number of scientific studies, heart patients have a poor tolerance to heat stress, which puts them at increased risk for complications such as chronic heart failure. or ventricular dysfunction, which results from heat intolerance.
Prevention of high temperature conditions, Boldsky says, often occurs through vital heart functions that increase sweat rates and increase blood flow to the skin to match body temperature.
When heart function is impaired, the body’s thermoregulation can be compromised when a person exercises or is exposed to high temperature during the summer, and these conditions can be overcome by:
1. Fluid replacement
One study indicates that fluid deficiency or water loss from the body not only impairs physical and mental performance, but also affects heart health. Severe dehydration caused by heat stress or prolonged exercise disrupts blood pressure regulation, reduces heart cell function, and impairs vascular function, causing a number of heart diseases.
2. Avoid strenuous exercise
Vigorous or strenuous exercise in hot weather can cause serious heart problems, according to a recent scientific study. This is mainly due to the increased need for oxygen in muscles and other vital organs.
When a person does vigorous exercise in the summer, excessive heat requires increased blood flow to the active muscles, and the body therefore needs more oxygen, and the double need for oxygen causes the heart to pump the blood more forcefully, which leads to excessive contraction. heart muscles and high blood pressure.
3. Avoid caffeine
A study shows that moderate caffeine and coffee consumption is associated with an increased risk of irregular heartbeat, whether it’s too fast or too slow.
Additionally, coffee is a natural diuretic and can increase the risk of dehydration.
4. Prevention of the risk of heat exhaustion
Heat exhaustion is the leading cause of dehydration. When people are exposed to extreme heat, many symptoms ensue, such as nausea, muscle cramps, breathing problems, and loss of body electrolytes.
These symptoms can make people weak and put them at increased risk for heart disease or heart attack.
5. Eat light meals
Eating healthy and in the form of snacks is the best option in the summer. Experts advise people with heart disease to avoid heavy meals in the summer to avoid heart complications.
6. Avoid peak heat periods
Outdoor activities should be limited during the summer, especially for people with heart disease. Experts advise avoiding going out during peak hours, between 10 a.m. and 2 p.m., when the heat waves are strongest because they can cause sunstroke.
For example, but not limited to, heat waves can increase the death rate in people with heart disease or make their condition worse.
8. Avoid drug interactions
Certain heart medications such as beta blockers can reduce blood flow in the body and prevent sweating, which is one of the main ways of losing body heat. Other drugs can also interfere with temperature regulation and cause changes in blood pressure.
You should therefore consult your doctor about medications, their uses during the summer and how to keep the body cool and maintain electrolyte balance.
General advice
There are other ways to maintain a healthy heart in the summer, including:
Eat less salt or salty foods.
• Eat fruits and vegetables that cool the body, such as watermelon, cantaloupe, cucumber, tomatoes, beans and frozen apples.
• Grill meat products instead of frying them and eat lean meats.
• In addition to eating less food, eat smaller meals at more frequent intervals.
• Stop smoking
Avoid stress
• Wear light-colored clothing that allows air to circulate to keep the body cool.
