Waking up breathless or gasping for air could signal fluid buildup in the lungs due to heart failure.

Morning chest tightness or pain, especially after waking, may be an early warning sign of a heart attack.

Sudden morning fatigue or heaviness in the body can indicate reduced blood flow caused by a weak heart.

Swelling in the feet or ankles after waking could point to poor heart function or fluid retention.

Irregular heartbeat or palpitations in the morning might suggest underlying arrhythmias or heart rhythm issues.

Nausea, lightheadedness, or sweating right after waking can also be early signs of heart distress.
