Smartphone: a new alarm bell for the heart?
People who spend long hours on their cell phones are more likely to develop heart problems, according to a study
In the digital age, our smartphone has become an extension of ourselves, an inseparable companion that accompanies us at every moment of the day. But this intimate relationship could hide risks for our health, especially for the heart.
The study
A recent study has raised concerns about a possible link between excessive mobile phone use and the onset of cardiovascular disease. Researchers, analyzing data from a large group of people, have observed that those who spend many hours glued to the screen are more likely to develop heart problems, especially if they are smokers or diabetics.
Harmful habits of life
But how is it possible that an object as harmless as a smartphone can damage our heart? The answer is to be found in the lifestyle habits that often accompany excessive use of mobile phones. Those who spend a lot of time browsing social media, playing games or watching videos tend to:
- Sleep less: Blue light emitted from screens interferes with the production of melatonin, the sleep hormone, making it harder to fall asleep and get a good night’s sleep
- Move less: Sitting for hours in front of the phone limits physical activity, a known risk factor for many diseases, including cardiovascular disease
- Be more stressed: Constant connection and information overload can increase levels of anxiety and stress, with negative consequences for mental and physical health
Chronic stress, for example, increases the production of hormones that raise blood pressure and promote plaque build-up in the arteries. Lack of sleep, on the other hand, alters metabolism and weakens the immune system, making the body more vulnerable to disease.
Correlation, not direct cause
It is important to note that the study found a correlation, not a direct cause. This means that it is not possible to say for sure that the use of mobile phone is the cause of cardiovascular diseases, but suggests that it could be an additional risk factor, especially in combination with other unhealthy lifestyles.
What can we do to protect our hearts?
- Set limits: We set times of the day dedicated to digital disconnect, like before going to sleep or during meals
- Encourage physical activity: We try to move as much as possible, even with short walks or by taking the stairs instead of the elevator
- Manage stress: We practice relaxation techniques such as meditation or yoga
- Create a sleep-friendly environment: Choose a comfortable mattress, darken the room and avoid using electronic devices at least an hour before going to bed
- Adopt a healthy lifestyle: We eat in a balanced way, limit our alcohol consumption and stop smoking
