When it comes to a heart attack, time is critical. While these situations may not be common, knowing how to respond can truly make a difference. And beyond emergency care, a few simple daily habits can help protect your heart without stress or drastic changes.

If you suddenly feel unwell: what should you do right away?

A heart attack can strike out of nowhere. If you experience symptoms — or see someone else who might be — here’s what to do:

First, call emergency services right away (in France, dial 15 or 112). Fast medical response is crucial.

Second, try coughing deeply and forcefully while waiting for help. Yes, really. Take a deep breath, then cough hard — like you’re trying to clear your lungs. This may help keep blood and oxygen flowing to your heart and brain until help arrives. It’s not a substitute for treatment, but it might buy you precious time.

How to care for your heart every day

Heart health starts with small, consistent habits. Here are some easy ways to support your heart daily:

Eat smart
Focus on a diet full of veggies, fruits, fiber, and whole grains. Cut back on saturated fats, and go for healthy fats like omega-3s, olive oil, and fatty fish. Bonus: it’s also great for your mood.

Get moving
You don’t need intense workouts — just 30 minutes a day of walking, swimming, dancing, or even gardening is enough to benefit your heart. Add light strength training once or twice a week for extra support.

Quit smoking
Smoking is extremely harmful to your heart. Take gradual steps to quit, explore helpful alternatives, and surround yourself with support. Every tobacco-free day is a win.

Manage stress
Chronic stress harms your heart over time. Practice calming habits like deep breathing, meditation, walks in nature, or creative hobbies. Find what relaxes you and stick with it.

See your doctor regularly
Routine checkups — blood pressure, cholesterol, CRP, ECG — help you track your health and catch any issues early. Staying informed is a smart move.

You don’t have to change your entire lifestyle overnight. Just a few daily choices, some movement, and a little self-care can go a long way in protecting your heart.

And remember: if you suddenly feel unwell, call for help and cough hard — it could make all the difference.
