What happens if you sleep next to your phone?

In today’s technology-driven world, it has become increasingly common for people to keep their cell phones on their nightstands while they sleep. However, there are some potential downsides to sleeping next to your phone that are important to consider.

Radiation exposure

One of the main concerns with sleeping near your phone is exposure to radiation. Cell phones emit radiofrequency energy, a form of non-ionizing radiation. The effects of long-term exposure to this type of radiation are still being investigated, but there are some studies that have found links between RF radiation exposure and increased cancer risk.

When you sleep next to your phone, you are exposing yourself to more RF radiation throughout the night than you would if you kept it further from your bed. The radiation exposure increases if you keep the phone on and especially if it is sending and receiving information through calls, texts, or apps.

The amount of radiation emitted depends on a few factors, such as how close the phone is to you, what position it is in, and how strong the cell signal is. The further away your phone is, the lower your RF exposure. So if you must sleep near your phone, try to keep it as far from your body as possible, such as on a nightstand rather than right next to your pillow.

Tips to limit radiation exposure

  • Keep your phone several feet from your bed.
  • Turn your phone to airplane mode to stop transmission of signals.
  • Use your phone’s low radiation settings, if available.
  • Avoid calling, texting, or using apps while in bed.

Disrupted sleep

Having your cell phone within arm’s reach makes it very tempting to check your notifications, social media, emails, or do some late-night web browsing. Using your phone before bed has been associated with poor quality sleep in several studies.

The blue light emitted from the display tricks your brain into thinking it’s daytime and suppresses melatonin production. Melatonin is an important hormone that regulates your sleep-wake cycle. Low melatonin makes it harder to fall asleep quickly and get good quality rest.

Phone use before bed also stimulates your mind, making it more difficult to relax. Activities like answering work emails, scrolling social feeds, or playing games are mentally engaging and delay your brain from transitioning into sleep mode.

In addition, you may be awakened throughout the night by incoming texts, calls, or app notifications if your phone remains on. This can negatively impact your sleep as your sleep cycles get interrupted.

Tips for limiting phone disruption

  • Turn off notifications and set your phone to silent or do not disturb mode.
  • Charge your phone outside your bedroom.
  • Power down completely at a set time before bedtime.
  • Engage in relaxing activities before bed like reading.
  • Use blue light blocking glasses if using your phone at night.

Negative health impacts

Poor sleep quality and inadequate sleep have been strongly linked to a number of adverse health outcomes. Therefore, the sleep disruptions caused by having your phone nearby at night may have downstream negative effects on your health.

Studies show that poor sleep increases your risk for:

  • Obesity
  • Diabetes
  • High blood pressure
  • Heart disease
  • Stroke
  • Mental health issues like depression

Lack of sleep also impairs your immune system, making you more likely to get sick after being exposed to a virus. Short sleep duration is connected to decreased cognitive performance, concentration, productivity, and safety issues related to drowsy driving.

Children and adolescents are particularly susceptible to the learning and behavioral problems that can result from phone-related sleep disturbances. Getting enough high-quality rest is crucial for physical health, mental health, cognitive function, and quality of life.

Should you sleep next to your phone?

Based on the potential downsides, it is generally recommended not to sleep with your cellphone next to your bed. The ideal situation is to charge your phone in another room overnight.

However, if you use your phone as an alarm clock or for work calls, you may not be able to keep it far away. In that case, take precautions to minimize the disruptions:

  • Switch phone to airplane mode or turn it off completely.
  • Disable WiFi/Bluetooth connections.
  • Make sure “do not disturb” is activated.
  • Place phone as far away as possible from your head.
  • Avoid using phone in bed right before trying to sleep.
  • Set a charging station outside of the bedroom if able to.

It is also wise to be aware of your phone habits and work to reduce bedtime usage. Limit use in the hour before bedtime and avoid reaching for your phone if you wake up at night. Keep the bedroom dark and cool to promote quality slumber.

Making simple changes to when and how you use your phone around sleeping hours can make a big difference in avoiding sleep disruption. Be mindful of your usage and take steps to protect your sleep health.

The Bottom Line

Sleeping right next to your cell phone may negatively impact your sleep quality and duration. The proximity increases radiation exposure, makes you more prone to sleep disturbances, and can contribute to adverse effects on your health. While occasional, careful bedtime usage is unlikely to cause harm, it’s best to keep phones away from your bed as much as possible.

Frequently Asked Questions

Is it bad to sleep with your phone under your pillow?

Yes, it is a bad idea to sleep with your phone under your pillow. This puts your head in very close proximity to the phone and increases your RF radiation exposure. It also makes it too easy to use the phone if you wake up at night, which can interfere with your sleep.

Should I sleep with my phone on airplane mode?

It’s a good idea to put your phone on airplane mode or switch it to offline mode when sleeping. Airplane mode suspends signal transmission from your phone, reducing RF radiation. Offline mode also blocks notifications, calls, and texts to prevent sleep disruptions.

Where should I put my phone when sleeping?

Ideally, charge your phone in another room away from your bedroom overnight. If you need it close by for an alarm, place it as far away as possible from your bed such as on a distant nightstand or dresser. Do not sleep with it in your bed or directly next to your pillow.

Can phone radiation cause cancer if you sleep next to it?

While more research is still needed, there is some evidence that the RF radiation emitted from cell phones may potentially increase cancer risk. Sleeping next to your phone could expose you to more of this radiation. However, if you follow precautions like keeping distance from your phone, risks are low.

Should kids sleep with phones in their rooms?

It is not recommended for children to sleep with cell phones in their bedrooms. Kids are more vulnerable to the impacts of phone exposure and sleep disruptions. Have your child charge their phone outside of their room and set boundaries around phone usage before bedtime.

The Dangers of Sleeping with Your Phone

Sleeping with your cell phone can be dangerous for several reasons:

Radiation Exposure

Cell phones emit radiofrequency (RF) radiation from their antennas. Some studies link RF radiation exposure to increased cancer risk, tumors, and other health effects, although more research is needed.

Sleeping next to your phone increases radiation exposure to your head and body, which may be harmful, especially after many years of continuous exposure.

Sleep Interruptions

Having your phone nearby makes you more likely to check it if you wake up at night. Using your phone before falling back asleep causes sleep interruptions and fragmentation that prevent you from getting enough deep, restorative sleep.

Light Exposure

The blue light emitted from phone and tablet screens tricks the brain into thinking it’s daytime. This delays the release of melatonin, the hormone that controls your circadian rhythm and makes you feel sleepy.

Distraction and Stress

Reading stressful emails or news on your phone stimulates your brain when you should be relaxing. The distraction keeps your mind turned “on” when you want it to wind down for sleep. This can delay the onset of sleep.

Decreased Productivity

Poor sleep has cascading negative effects on your daily functioning. Drowsiness, cognitive deficiencies, lack of focus, and irritability from phone-induced sleep disruptions lower your performance and productivity during the day.

Tips for Limiting Phone Exposure at Night

If you need your phone nearby overnight, follow these tips to reduce the risk of sleep disturbances:

  • Silence your phone and disable vibration.
  • Switch your phone to airplane mode.
  • Turn off cellular data and WiFi.
  • Set your phone screen to the lowest brightness.
  • Use do not disturb or sleep mode.
  • Face the phone screen-down.
  • Keep your phone at least several feet away from your bed.
  • Set your phone screen to automatically filter out blue light at night.
  • Charge your phone outside your bedroom if possible.
  • Avoid using your phone if you wake up at night.
  • Use a traditional alarm clock instead of your phone if needed.

The Bottom Line

While occasionally having your phone nearby as you sleep likely poses little risk, regularly sleeping next to your phone can negatively impact your rest. Take sensible precautions to reduce exposure to phone radiation and blue light emissions, avoid sleep interruptions, and ensure enough high-quality sleep every night.

Frequently Asked Questions

Is it dangerous to sleep with my cell phone under my pillow?

Sleeping with your cell phone under your pillow is very dangerous due to the close proximity to your head. This maximizes your exposure to the RF radiation emitted from the phone, which may increase your risk of brain tumors and other health issues. The metal materials in phones may also overheat. It’s best to keep your phone away from your bed altogether while sleeping.

What kind of radiation does a phone emit while sleeping near you?

Cell phones emit a form of radiation called radiofrequency (RF) radiation from their antennas when in use. The main frequency of radiation from smartphones that may impact health is from cellular signals in the 5G frequency range. However, your phone still emits some RF radiation when not in active use unless switched to airplane mode. Sleeping near your phone means greater long-term exposure to this type of radiation.

Should I face my phone screen-down if I sleep next to it?

Yes, you should face your phone screen-down if you must keep it near your bed while sleeping. Cell phone screens emit a high amount of blue light, which can impair melatonin secretion and your circadian rhythm when exposure occurs before bedtime. Facing your phone down keeps the light from shining in your face if you open your eyes, allowing you to maintain better quality sleep.

How close can my phone be without affecting my sleep?

Ideally, your phone should be at least several feet away from your bed while sleeping to prevent negative effects. Having your phone within arm’s reach makes it too easy to use before bed, and the closer the phone the greater your radiation exposure. If possible, charge your phone in another room overnight for the best sleep.

Can I just put my phone on airplane mode while sleeping?

Switching your phone to airplane mode is better than leaving it on during the night, as this suspends RF radiation emissions from cellular, WiFi and Bluetooth signals. However, your phone will still emit some radiation in airplane mode, so it’s better to keep it away from your immediate sleeping space even in this setting. Airplane mode also won’t block the light and mental stimulation of using your phone before bed if it remains within reach.

In Conclusion

Habitually sleeping next to your cellphone may be convenient but poses risks that can negatively impact your rest and long-term health. Take sensible precautions to maximize your sleep quality and duration. Keep your distance from your phone overnight, limit pre-bed usage, and practice good sleep hygiene habits. Prioritize your sleep health by separating from your phone for healthier, more restorative nights.
