Heat wave warnings have been issued for several states, bracing for continued heatwaves in the coming months. The scorching heat of summer not only increases sweating but also strains vital body functions, creating a serious risk of health complications from heat stroke and dehydration. Heatwaves can also affect heart function. In order to regulate body temperature, the heart has to work extra hard to ensure blood flow. This can put strain on vital organs, and a lack of proper cardiovascular care can make events like heart attacks more likely.

Drinking enough water in hot weather can support the body’s normal functioning. It is also important to avoid peak sun exposure, wear cotton clothing, and use air conditioning regularly to reduce the effects of heatwaves.

What is the connection between heat waves and heart attacks?

“During heat waves, the body’s thermoregulatory mechanisms are put to the test. To cool down, the body relies on sweating and increased blood flow to the skin. This puts a greater strain on the heart, which People with healthy cardiovascular systems can withstand this stress, but people with pre-existing heart disease are at increased risk and can potentially It can cause seizures,” Dr. Kattale added.

“The human body is primed to function optimally between certain ambient temperatures. Extreme temperatures cause changes in metabolism, leading to malfunction of various organs in the body. Extreme temperatures impede function. During extreme heatwaves, such as those seen in the subcontinent in the summer, sweating increases and fluid loss occurs, leading to dehydration. The heart has to work very hard to maintain sufficient circulation. This can increase the strain on the heart and increase the strain on the heart. It can lead to heart attacks, especially in people who already have underlying conditions such as high blood pressure and diabetes,” said Dr. Sashi K. Srivastav, Consultant Interventional Cardiologist, Yashoda Hospital, Hyderabad.

Signs and symptoms of heart disease during a heat wave

Symptoms of heart disease during a heatwave include profuse sweating, weakness, cold, clammy skin, fainting, and vomiting. These signs indicate heat exhaustion or heat stroke, both of which require immediate medical attention as they can escalate to serious complications such as a heart attack.

Steps to beat the heat

Summer heart care includes prioritizing hydration, maintaining electrolyte balance, and avoiding excessive exercise during hot weather. In addition, people with cardiovascular disease should adhere to prescribed medications and consult their health care provider for individual recommendations.

“Precautions during heatwaves are especially important for people with cardiovascular problems. Staying hydrated is important to prevent dehydration, which can put a strain on the heart. Avoiding sunlight, using a fan or air conditioner, and wearing lightweight clothing can also help reduce the effects of heatwaves, “the effects of extreme heat,” says Dr. Katale.

Dr. Srivastav says people with pre-existing heart conditions should avoid excessive exercise, stay hydrated regularly and ask their doctors to adjust the dosage of some medications.

“Patients taking medications such as diuretics in the summer may experience fatigue and dehydration. Doses of these medications should be adjusted to account for increased sweating during intense heat. Vigorous exercise and physical activity can activate the sympathetic nervous system, which increases the chance of a heart attack. Exposure to extreme heat can also cause dizziness and fainting, which can cause heart damage. People with problems should exercise less during peak periods, summer months, and periods of extreme heat. They should stay well hydrated and stay indoors. The dosage of some medications may be adjusted by your doctor. ”says the expert.
