The risk of heart attack doubles at this time of day; be cautious about these 7 reasons
Doctors and researchers have found that the risk of a heart attack is almost twice as high in the early morning hours, especially between 6 AM and 10 AM. This is the time when the body undergoes several biological changes that put extra stress on the heart. If you already have high blood pressure, diabetes, obesity, or a sedentary lifestyle, the danger increases further.
7 Reasons Why Morning Time Increases Heart Attack Risk
- Sudden Rise in Blood Pressure – As soon as you wake up, your blood pressure naturally spikes, straining your arteries.
- Increased Heart Rate – The heart starts working harder in the morning to prepare the body for the day.
- Hormonal Surge (Cortisol & Adrenaline) – Stress hormones are released in higher amounts, which can trigger clotting and vessel constriction.
- Blood Thickening – After long hours of sleep without water, the blood becomes slightly thicker, increasing clot risk.
- Plaque Rupture – Morning pressure and hormonal changes can cause vulnerable plaque in arteries to rupture.
- Higher Platelet Activity – Platelets become more active in the morning, increasing the chance of clot formation.
- Sudden Physical or Mental Stress – Rushing, overexertion, or morning anxiety can put an extra load on the heart.
✅ Prevention Tip: Start your day calmly, avoid rushing, stay hydrated, take prescribed medicines on time, and maintain a heart-healthy lifestyle.
