Heart disease is a leading cause of global mortality, affecting individuals of all ages. An easy 3-second morning heart test can help identify potential heart conditions timely. It involves raising both arms above your head in bed and checking for tightness in the chest, numb fingers, or sudden fatigue. Other warning signs include chest pain, especially during physical activity, pain spreading to the jaw or arm, and persistent shortness of breath alongside fatigue. These symptoms are crucial indicators of heart problems and require prompt medical attention.
