Extreme heat… Danger to watch out for regarding the "heart"
When external temperatures rise, the body tries to release heat by sweating and dilating blood vessels at the skin, resulting in the heart having to work harder to pump blood to various parts and to maintain stable blood pressure. For those who already have heart disease or high blood pressure, this condition can trigger severe symptoms.
Why does summer pose a risk for heart disease?
- Dehydration: When we sweat a lot, blood becomes more viscous, causing the heart to use more force to contract and increasing the risk of blood clots.
- Abnormal rapid heartbeat: To release heat, the heart beats faster, which can lead to heart failure in individuals with weak heart muscles.
- Fluctuating blood pressure: Hot weather causes blood vessels to dilate, and blood pressure may drop suddenly, causing dizziness or fainting.
Warning signs that the "heart is working too hard"
If you are in the sun or in a hot place and experience the following symptoms, rest immediately and observe the symptoms:
- Chest pain, tightness, or a feeling of discomfort in the chest radiating to the arms or neck.
- Palpitations, irregular heartbeat, or an abnormally fast heartbeat.
- Shortness of breath, panting, or exhaustion even without heavy exertion.
- Dizziness, lightheadedness, or feeling like you are about to faint.
Guidelines for prevention and heart care in summer
- Drink enough water: Sip water frequently throughout the day to maintain blood concentration.
- Avoid alcohol and caffeine: Because they have a diuretic effect, causing the body to lose more water.
- Take prescribed medications strictly: Especially blood pressure medication and blood thinners (never stop medication on your own).
- Stay in well-ventilated areas: If you feel extremely hot, use a damp cloth to wipe the joints to help dissipate heat.
