Smartphones have become an essential part of everyday life, but the way people carry and use them has raised questions about prolonged close contact between mobile devices and the body.
Many people routinely place their phones in their pockets, under their pillows or directly against their bodies for hours at a time. While current scientific evidence has not established that normal exposure to mobile phone radiofrequency radiation causes health problems, reducing unnecessary close contact is a simple precaution for people who remain concerned about exposure.

Here are three places where it may be better to avoid keeping your phone for prolonged periods...READ THE FULL ARTICLE HERE .
1. Inside Your Trouser or Front Pocket
Keeping a phone in a trouser pocket is one of the most common habits, particularly when people are outside the home.
Because the device can remain close to the body for several hours, some people choose to carry it in a bag or another location that creates more distance between the phone and their body.
The amount of radiofrequency energy absorbed by the body depends partly on the distance between the phone and the body. Mobile phones transmit and receive radiofrequency signals, and exposure is generally higher when a phone is used very close to the body. (World Health Organization)
For people who want to reduce unnecessary exposure, practical steps include:
• Keep the phone in a bag rather than directly against your body when convenient.
• Avoid keeping the phone pressed tightly against the skin for prolonged periods.
• Use speaker mode or headphones during long calls.
• Consider airplane mode when you do not need mobile connectivity.
2. Inside Your Shirt or Bra
Some people carry their phones inside clothing because it is convenient, but keeping an active phone pressed directly against the skin for long periods can be avoided by simply creating some distance.
There is currently no established evidence that placing a phone against breast tissue or other parts of the body causes cancer. However, if reducing radiofrequency exposure is a personal concern, carrying the device away from the body is a straightforward precaution.
The World Health Organization says the main established interaction between radiofrequency electromagnetic fields and the body at sufficiently high levels is tissue heating, while available evidence has not confirmed health consequences from low level exposure. (World Health Organization)
A better option is to keep the phone in a handbag, backpack or another location where it is not constantly pressed against the skin.
3. Under Your Pillow or Directly Beside Your Head While Sleeping
Keeping a phone under a pillow may appear harmless, especially for people who use their devices as alarms. However, it is not a good sleeping habit for several practical reasons.
A phone can become warm during charging or intensive use, and placing it underneath bedding can interfere with heat dissipation.
There is also the issue of sleep disruption. Notifications, calls, screen light and the temptation to check social media can make it harder to maintain healthy sleeping habits.
If you need your phone as an alarm clock, consider placing it on a bedside table rather than directly under your pillow.
People who want to reduce radiofrequency exposure while sleeping can also increase the distance between themselves and the phone or use airplane mode when mobile connectivity is unnecessary.
Does Phone Radiation Cause Cancer?
This is where it is important to separate health precautions from established scientific evidence.
Mobile phones emit radiofrequency radiation, which is a form of non ionising radiation. Unlike ionising radiation such as X rays, it does not have enough energy to directly ionise atoms.
According to the US Food and Drug Administration, the weight of scientific evidence has not linked radiofrequency radiation from mobile phones with health problems. The World Health Organization has similarly stated that current evidence does not confirm health consequences from low level electromagnetic field exposure. (U.S. Food and Drug Administration)
That does not mean researchers have stopped studying the subject. Long term effects of mobile phone exposure continue to be investigated, particularly because mobile phones are used extensively across the global population.
The sensible approach is therefore to avoid unnecessary fear while adopting simple habits that can reduce prolonged close contact with the device.
People With Pacemakers Need Extra Precautions
There is one important exception where keeping a phone away from the body is particularly relevant.
People with certain implanted medical devices, including pacemakers and implantable cardiac defibrillators, should follow medical advice regarding mobile phones and other electronic devices.
The FDA recommends that people with implanted medical devices keep phones and smartwatches that may create magnetic interference at least six inches away from the implanted device and avoid carrying them directly over the implant. (U.S. Food and Drug Administration)
Anyone with an implanted medical device should follow the instructions provided by their healthcare professional and the device manufacturer.
Simple Ways to Reduce Close Phone Exposure
You do not need to stop using your smartphone to reduce the amount of time it spends directly against your body.
A few simple habits can help:
• Keep your phone in a bag when possible instead of directly against your body.
• Use speaker mode or headphones during lengthy calls.
• Avoid sleeping with the phone under your pillow.
• Keep the phone away from implanted medical devices where applicable.
• Use airplane mode when you do not need cellular connectivity.
• Avoid unnecessary prolonged phone use when the device is pressed against your skin.
• Follow the manufacturer’s instructions regarding body worn use and safe distances.
The Bottom Line
Smartphones are an important part of modern life, and there is currently no strong scientific basis for claiming that ordinary mobile phone use is proven to cause serious health problems. (U.S. Food and Drug Administration)
However, keeping a phone directly against your body for extended periods is not necessary. Creating some distance, particularly while sleeping or when carrying the device for several hours, is a simple precaution for anyone who wants to minimise radiofrequency exposure.
The most important message is not to panic about your phone, but to use it sensibly. For most people, simple changes such as keeping the device away from the body when it is not being used and avoiding phone use during sleep can also support better everyday habits.
