Slight fluid retention may be normal (especially in summer or when standing for long periods of time), but ankles or calves that swell daily, with no obvious cause, can indicate a venous return problem. Dr. London explains that this can indicate that the heart is having difficulty moving blood back up properly.
The right reflex: Watch if the swelling disappears during the night or if it persists. And don’t delay talking to a health professional.
How do we measure the strength of our heart?

No need for complicated examinations. A cardiac ultrasound (called an echocardiogram) measures what is called the ejection fraction: this is the percentage of blood expelled with each beat. A fit heart is between 65 and 70%. Below that, we speak of weakened heart function.
Why is it important to know?
A strong heart allows you to better manage stress, effort… and even surgical interventions, if one day it becomes necessary. According to Dr. London, this is a key factor in recovering well after surgery. But even without medical concerns, a healthy heart also means more energy on a daily basis.
And how can it be strengthened naturally?
The good news is that simple habits can go a long way!
- Practice gentle but regular physical activity (brisk walking, swimming, dancing, etc.)
- Get enough sleep to allow your heart to regenerate
- Manage stress with calming activities (yoga, gardening, breathing…)
- Take care of your teeth and intestines: their health also influences the health of the heart
- Eat a balanced diet and limit excess salt, sugar and saturated fats
Because a heart that is doing well is a body that radiates vitality. Listen to the little signs… And never hesitate to consult, even if you have a simple doubt. Prevention is better than cure!
