New Delhi, 19 May 2025: With temperatures soaring across the globe, health experts are warning of a sharp increase in summer-related heart attacks. Extreme heat can put an enormous strain on the cardiovascular system — especially in older adults, people with pre-existing heart conditions, and even younger individuals who ignore early warning signs.
A heart attack rarely comes without a warning. In fact, your body may start sending subtle signals — sometimes just an hour before it strikes. Recognizing these signs early could mean the difference between life and death.
Here are 7 early symptoms your body might show right before a heart attack, especially during the hot summer months.
Sudden Chest Discomfort or Tightness
The classic symptom of a heart attack is chest pain, often described as pressure, squeezing, or tightness in the center or left side of the chest. In summer, this may be mistaken for heat exhaustion or dehydration. If it lasts for more than a few minutes or comes and goes, seek emergency help immediately.
Unexplained Sweating (Cold Sweat)
While sweating is normal in summer, cold sweat — particularly when you’re not exerting yourself — is a major red flag. It may feel clammy or sticky and usually accompanies other symptoms like chest discomfort or nausea. This occurs because your nervous system goes into fight-or-flight mode as your heart struggles to pump blood.
Shortness of Breath
Struggling to catch your breath while resting or doing light activity could signal an impending heart attack. The heart and lungs work closely together, and when the heart fails to pump effectively, it affects your breathing. In summer, people may confuse this with the heat or humidity, which makes it even more dangerous.
Nausea or Light-Headedness
Feeling dizzy, faint, or nauseated during a hot day could be more than heatstroke. Light-headedness paired with other heart attack symptoms could indicate your brain isn’t getting enough oxygen due to poor blood flow. This symptom is more common in women and may not be immediately recognized as heart-related.
Fatigue or Sudden Weakness
If you feel extremely tired, weak, or sluggish out of nowhere — even after light activities — it could be your heart’s way of telling you it’s in trouble. This is often reported in the hour or hours before a heart attack, especially during high-heat days that already push your body to the edge.
Pain Radiating to the Arm, Jaw, Neck, or Back
Heart attack pain doesn’t always stay in the chest. It can radiate to your left arm, shoulders, neck, jaw, or back. In many cases, people think they’ve pulled a muscle or slept wrong. If this kind of pain occurs along with any of the above symptoms, don’t ignore it.
Irregular or Rapid Heartbeat
A fluttering sensation or sudden irregular heartbeat can be a serious sign of cardiac distress. During summer, dehydration and electrolyte imbalances can trigger arrhythmias, making your heart work harder. If you feel like your heart is racing or skipping beats, it could signal a pending cardiac event.
Don’t chalk up unusual fatigue, dizziness, or chest tightness to the weather. These could be warning signs of a heart attack — especially if they appear suddenly and persist for more than a few minutes. Always seek medical attention if in doubt.
This summer, stay hydrated, avoid peak sun hours, and listen to your body. Early action can save your life.
