California Just Issued a Health Warning for Cell Phones—But It's Not as Scary as It Seems

The cell phone's reputation as a health risk is nearly as old as the technology itself. Worried consumers have blamed the device for everything from cancer to infertility, but with little evidence to back up these claims, experts have been split on the issue. Now California has come out with a list of guidelines in response to these supposed risks, Forbes reports.

The California Department of Public Health (CDPH) released the warning [PDF] earlier in December following a lawsuit from University of California-Berkeley researcher Joel Moskowitz. Moskowitz claimed that the state of California was putting citizens in danger by withholding information on the potential side effects of cell phone usage.

The newly released document focuses on avoiding radiofrequency (RF) energy specifically. Cell phone signals are one source of RF energy, and because it's a type of radiation, it's a common source of phone-related cancer fears. The CDPH recommends reducing exposure to the energy waves by sending text messages instead of making calls, using the speakerphone or a headset when talking on the phone, and carrying your phone in a bag rather than your bra, pocket, or belt holster. The department also suggests breaking the habit of sleeping with your phone in your bed, or at least turning it off or activating airplane mode before falling asleep.

Cell phones release more RF energy at some points than others, like when you're traveling in a vehicle, streaming or downloading content, or using a phone in an area where the signal is weak. But even when RF energy from cell phones is at its strongest, it's still not as great as the radiation from X-rays or ultraviolet rays from the Sun, and the jury's still out over whether it poses a threat to your DNA at all.

Past research linking RF energy to brain cancer has come with some major caveats: One study found that rats exposed to RF energy were more likely to develop brain tumors, but those rats were hit with seven times the radiation a person would get from a cell phone (and also they were rats, so not a perfect replacement for humans). Even the CDPH acknowledges the limits of the evidence in the studies it cites:

These studies do not establish the link definitely, however, and scientists disagree about whether cell phones cause these health problems and how great the risks might be.

So if it makes you comfortable, go ahead and sleep with your cell phone on your night stand instead of under your pillow. But maybe don't use the warning as an excuse to start declining all your calls.

Stop Your Snoring and Track Your Sleep With a Wi-Fi Smart Pillow

Everyone could use a better night's rest. The CDC says that only 66 percent of American adults get as much sleep as they should, so if you're spending plenty of time in bed but mostly tossing and turning (or trying to block out your partner's snores), it may be time to smarten up your sleep accessories. As TechCrunch reports, the ZEEQ Smart Pillow improves your sleeping schedule in a multitude of ways, whether you're looking to quiet your snores or need a soothing lullaby to rock you to sleep.

After a successful Kickstarter in 2016, the product is now on sale and ready to get you snoozing. If you're a snorer, the pillow has a microphone designed to listen to the sound of your snores and softly vibrate so that you shift positions to a quieter pose. Accelerometers in the pillow let the sleep tracker know how much you're moving around at night, allowing it to record your sleep stages. Then, you can hook the pillow up to your Amazon Echo or Google Home so that you can have your favorite smart assistant read out the pillow's analysis of your sleep quality and snoring levels the next morning.

The pillow is also equipped with eight different wireless speakers that turn it into an extra-personal musical experience. You can listen to soothing music while you fall asleep, either connecting the pillow to your Spotify or Apple Music account on your phone via Bluetooth or using the built-in relaxation programs. You can even use it to listen to podcasts without disturbing your partner. You can set a timer to turn the music off after a certain period so you don't wake up in the middle of the night still listening to Serial.

And when it's time to wake up, the pillow will analyze your movements to wake you during your lightest sleep stage, again keeping the noise of an alarm from disturbing your partner.

The downside? Suddenly your pillow is just another device with a battery that needs to charge. And forget about using it in a place without Wi-Fi.

The ZEEQ Smart Pillow currently costs $200.

Want to Fall Asleep Faster? Add This Tweak To Your Bedtime Routine

There are countless reasons people have trouble falling asleep. It could be physiological, as in the case of airway-obstructing sleep apnea, or it could be because you’ve had too much caffeine too late in the day. But some of us experience delayed slumber for a different reason: Our racing minds can’t quite shift into a lower gear. If you fall into this hyper-vigilant category, there’s a side effect-free way to try and resolve the problem.

In a study published in the Journal of Experimental Psychology, researchers found that subjects who were tasked with writing out a to-do list for the following day (or days) before bed were able to fall asleep more quickly than other subjects who wrote about only what they had done that day.

The test, performed at Baylor University, recruited 57 people between the ages of 18 and 30 and kept them overnight in a sleep lab. Those who wrote down their planned tasks could use bullet points or paragraphs and fell asleep an average of nine minutes faster than subjects who didn’t. The more specific the list, the faster they were able to crash.

Researchers believe that the act of writing down responsibilities might be one way the brain can let go of a person’s obligations. (Thinking of what you have to do won’t have quite the same effect.) It was a small study, but considering how non-invasive it is, it might be worth trying if you're experiencing a lot of tossing and turning.
