Globally, more people die from heart diseases than from any other factor. Particularly in those who already have heart disease, extreme heat can have a major negative impact on heart health. The effects of high temperatures on the body can be especially hard on the heart. These effects include dehydration, elevated metabolic demand, increased blood clotting, electrolyte imbalances, and increased systemic inflammatory responses. As per certain studies, heat can cause ischemic heart disease, stroke, heart failure, and arrhythmia.
In hot weather, your body has to work harder to maintain a normal core temperature, which puts additional strain on your kidneys, lungs, and heart. This implies that having a cardiac condition may put you at higher risk. The intense heat of summer makes heart health maintenance more tough. The deaths and disabilities from cardiovascular disease (CVD) significantly rise with rising temperatures. Research has revealed an alarming relationship: a mere 1 degree Celsius increase in temperature corresponds to a 2.1% increase in deaths from CVD and a 0.5% increase in illnesses associated with it.

The body's internal systems can be severely impacted by the environment. Heat waves, whether we recognise it or not, have the potential to negatively impact physiological processes and, in the worst case, lead to organ failure, especially heart failure. Blood rushes to the skin during heat stress in order to release body heat. To pump blood, the heart has to work harder, which can be particularly dangerous for those who have pre-existing cardiovascular disease.
Thus, it's especially crucial to stay hydrated and cool. If you are perspiring more than usual, drinking lots of fluids will help compensate and prevent a dangerous drop in blood pressure.
How Does Summer Increase Heart Health Risks?
Following are the risks that increase for heart health during summers:- Dehydration: inadequate fluid intake can result in dehydration that lowers the blood pressure, decreasing the blood volume of blood circulating in the body. This increases the heart’s workload, making it work harder.
- Heat Stroke: Excessive exposure to high temperatures and high humidity overheats the body, leading to heat exhaustion or heat stroke. Both these conditions increase stress on the heart.
- Elevated Heart Rate: The body has to work harder to cool itself in hot weather. The heart has to work harder and beat faster as a result of this.
- Electrolyte Imbalance: Sweating excessively can cause the loss of vital electrolytes like potassium and sodium. Electrolyte abnormalities raise the risk of arrhythmias and can interfere with heart function.
- Excess Physical Activity: Participating in demanding outdoor pursuits without adequate acclimatization may result in overdoing it and further stressing the heart.
- Effect of Medications: Certain drugs, like beta-blockers and diuretics, can alter how the body reacts to heat. These drugs may hinder the body's natural cooling process, raising the possibility of heat-related illnesses.
- Increased Air Pollution: Elevated summertime ozone and other pollution levels. Pollutants can worsen heart attack and stroke risk by aggravating cardiovascular and respiratory disorders.
- Blood Pressure Changes: Blood vessels may dilate when it gets hot. This may cause blood pressure to drop, which could be dangerous for those who already have certain heart issues.
10 Tips For Healthy Heart In Summer
Following are the few tips that can enhance your heart health in summers:- Stay hydrated: Be sure to stay hydrated by consuming lots of water or other beverages. While water is the ideal beverage, other options include milk, sports drinks, fruit juice, and diluted squash. For example, if you have been advised to limit your fluid intake due to heart failure, you should consult your general practitioner.
- Avoid alcohol: Alcohol can make you more dehydrated.
- Take Nutritious Diet: Appreciate cold foods that are high in water content and rich in vitamins and minerals, like fruit and salads.
- Keep Your Home Cool: When you are inside your home, try to keep it cool. If you have shutters, cover windows that are exposed to direct sunlight; if not, cover them with blinds or curtains. If it's colder outside than inside your house, open the windows. Your home may become hotter if you leave on any lights or electrical equipment.
- Wear Comfortable Clothes: Wear light, loose-fitting clothing and spend time in the coolest area of your home, especially when you're sleeping.
- Stay Indoor During Hotter Hours: It can be cooler to go outside during the hottest part of the day, which is between 11 a.m. and 3 p.m., especially if you can spend some time in the shade.
- Avoid Excessive Physical Activity: Avoid intense physical activity, wear a hat, carry some water, and apply sunscreen.
Conclusion
Stay hydrated this summer by drinking lots of water, limiting your intake of alcohol, and limiting your caffeine intake to maintain heart health. Exercise in the early morning or late at night instead of doing anything physically demanding when it's hot outside. Put on airy, light clothing to help control your body temperature. Keep an eye on your diet, emphasizing vegetables and fruits, and reducing sugar and salty foods. Recognise the warning signs of heat-related illnesses, such as heat exhaustion and heat stroke, and get help right away if you experience any of these symptoms. Lastly, regarding the management of medications that might impact your heat tolerance, speak with your doctor about it. By following these guidelines, heart health can be preserved all summer long.If you are looking forward to the best heart care, then reach out to our experts at Asian Heart Hospital for comprehensive care.
