Does keeping a phone in your shirt pocket harm your heart?

Keeping a smartphone in a left shirt pocket does not cause abnormal heart rhythms in healthy people, according to medical experts. Smartphones emit radiofrequency signals to connect with mobile networks and wireless devices. These signals are non-ionising, which means they lack enough energy to directly damage DNA the way X-rays do. Current scientific evidence has not established that everyday exposure to these signals leads to heart rhythm disorders for the general population.

Sensation and Anxiety

People often wonder why they feel more aware of their heartbeat when carrying a phone close to their body. A phone vibrating against the body makes a person notice sensations in that area more easily. If someone is already anxious or pays close attention to their heartbeat, they notice normal bodily feelings more readily. Feeling a heartbeat more clearly does not mean the heart rhythm has actually changed.

Cardiac Devices

While most people do not need to worry, individuals with implanted cardiac devices must take precautions. Some phones and electronic devices contain magnets that can temporarily interfere with devices like pacemakers and implantable cardioverter-defibrillators when held very close. Strong magnetic fields can activate special modes in these devices or temporarily alter their function. People with such medical equipment should follow device manufacturer guidelines regarding phone placement and safe distances.

Context

Heart palpitations and the sensation of skipped beats can stem from many common everyday factors rather than mobile phones. Elements like caffeine consumption, stress, dehydration, poor sleep, and underlying heart conditions contribute to these feelings. Anyone experiencing palpitations alongside chest pain, fainting, or severe breathlessness should seek urgent medical attention.
