Heart attacks have become the leading cause of death worldwide, often triggered by stress and unhealthy diets. Thankfully, you can protect your heart by managing stress and eating better. Recognizing early warning signs can also be life-saving.

Here are six symptoms that may appear up to a month before a heart attack:

Shortness of breath – Insufficient oxygen affects heart function.
Cold or flu-like symptoms – Often reported before a heart attack.
Chest pressure – A strong warning sign; seek medical help immediately.

Weakness and fatigue – Poor circulation limits muscle strength.
Cold sweats and dizziness – Caused by reduced blood flow to the brain.
Unusual drowsiness – Persistent tiredness may signal decreased heart function.
If you experience any of these signs, consult your physician. Early detection and a healthier lifestyle can greatly reduce the risk of heart attacks.
