12 Precautions to Protect Your Heart Health During Hot Weather

12 Precautions for Protecting Your Heart Health in the Heat As summer brings extreme temperatures, they pose numerous risks to heart health and can lead to life-threatening conditions. Acıbadem Üniversitesi Atakent Hastanesi emphasizes that misconceptions such as "my heart is strong as stone," "the sun won't harm me," and "if I don't drink water, I drink tea" put heart health at risk during extreme heat. "Summer heat affects not only heart patients but also healthy people at risk for heart disease. For example, what is dismissed as 'heat fatigue' can be followed by a heart attack! For this reason, certain rules must be followed carefully; some seemingly simple precautions can be life-saving," says Prof. Dr. Ahmet Karabulut, Cardiologist. Prof. Dr. Ahmet Karabulut, Cardiologist, explained 12 essential precautions for heart health in summer and provided important warnings and recommendations.

Increase your water intake

During summer, fluid loss from the body increases through perspiration and breathing, and the body's water needs rise. Therefore, increasing water consumption in summer months will prevent complications triggered by dehydration such as heart palpitations, shortness of breath, and blood thickening. Drinking 10 glasses of water daily during summer provides significant benefits for body resistance and health.

Do not delay your dinner time

In winter, as darkness falls early, dinner is consumed earlier, but in summer it often gets pushed to after 21:00. However, dinner eaten at this time negatively affects blood sugar and blood pressure regulation. Eating dinner at earlier hours and avoiding meals after 21:00 will have a positive effect on our health.

Do not stay exposed to the sun for long periods

Prof. Dr. Ahmet Karabulut states: "Spending long periods in summer sun—sunbathing, exercising, or working—can deplete your body's energy levels. Particularly with sun exposure accompanied by perspiration, weakness, headache, concentration problems, and nausea are signs of heat fatigue caused by solar radiation. Heat fatigue causes fluid loss in the body, blood thickens, and there is a tendency toward clotting. In people with vascular stiffness or those at risk, a heart attack can develop. Therefore, avoid prolonged sun exposure."

Precautions to take when going outside

Avoiding the noon sun, wearing a hat, and wearing thin cotton clothing in light colors will prevent heat fatigue and the negative effects caused by harmful sun rays. Avoid dark-colored clothing during summer months. This is because sun rays are waves that produce heat, and they move more slowly over dark colors. This causes dark-colored garments to attract more sun rays and generate more heat. Light-colored clothing produces less heat and has a lower perspiration risk.

Limit caffeine

Since fluid loss from the body will already increase during summer, caffeinated beverages such as tea and coffee will increase this loss further due to their diuretic effects. Therefore, caffeine and coffee consumption should be restricted in summer, and carbonated beverages should be avoided. For example, a glass of natural mineral water and a chilled kefir smoothie enriched with fresh seasonal fruits would be a refreshing and healthy alternative for summer heat.

Avoid alcohol

As summer arrives, outdoor spaces become social gathering places. However, particularly in hot weather, alcohol consumption causes heart rhythm irregularities and increases the risk of heart attack. Therefore, alcohol should not be part of the definition of socializing; healthy, cooling beverages should be preferred instead.

Avoid foods with additives

Ice cream is among the most popular foods for cooling off during summer. However, packaged, additive-laden, and sugary foods negatively affect blood sugar and cholesterol balance. They directly increase the risk of vascular stiffness. Therefore, prefer natural foods and stay away from foods with additives.

Do not disrupt your sleep schedule

Quality sleep, which is the body's time for repair, directly affects both our physical and mental health. Following a poor night's sleep, blood pressure, heart rhythm, blood sugar, and cholesterol balance are disrupted. Brain activity is negatively affected. Nighttime sleep is more restorative than daytime sleep. As nights become shorter in summer and sunrise moves to earlier hours, this should be taken into account. To ensure 7 hours of quality sleep, it is necessary to fall asleep before midnight.

Do not overdo swimming

Swimming, an indispensable summer activity, is recommended for general body health as well as heart and vascular health. However, particularly swimming for long periods in cold waters can cause body temperature to drop below normal levels (hypothermia), which can lead to many serious problems ranging from heart rhythm irregularities, low blood pressure, and palpitations to cardiac arrest. For health purposes, swimming for 30 minutes daily at specified breathing intervals is sufficient exercise. Rather than swimming straight out from shore into open water, swimming parallel to the shore would be safer, especially for people with heart and vascular disease.

Do not stop taking your medications

Prof. Dr. Ahmet Karabulut states: "Since heart and vascular disease are chronic conditions, drug therapy must be continuous. This medication regimen is often interrupted in summer due to travel and holidays. Stopping medications in people with heart and vascular disease can lead to serious health problems. Since fluid needs increase during summer, people using diuretics can develop rapid fluid deficiency and kidney problems. Heart failure and hypertension patients may require summer adjustments to their diuretic therapy. Therefore, be sure to consult your physician."

Stay away from smoking

Scientific research clearly demonstrates the harmful effects of tobacco and tobacco products such as cigarettes, shisha, and electronic cigarettes on heart health. Particularly in hot weather, tobacco use disrupts heart rhythm and further increases the risk of heart attack.

Reach your ideal weight with a healthy diet

Increased socialization during summer months and the impact of vacation often lead to changes in eating habits that result in weight gain. Excess weight is a triggering factor in many diseases ranging from diabetes to hypertension and heart disease. To prevent weight gain during summer, weigh yourself regularly each week and keep a record of your weight. Avoid overindulging at all-inclusive resort meals. For those who have a late breakfast, combining lunch and dinner would be beneficial.
