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.

High Levels of Arsenic Found in Bottled Water From Whole Foods and Dr Pepper

If you're concerned about drinking unfiltered water from your tap at home, bottled water isn't automatically the safer option. As USA Today reports, tests conducted by the California nonprofit Center for Environmental Health (CEH) found that the arsenic levels in two popular bottled water brands exceed those found in the state's tap water.

The affected brands are the Keurig Dr Pepper-owned Peñafiel and Whole Foods-owned Starkey. The arsenic content in each product hasn't prompted a federal recall, but CEH discovered that it does violate state guidelines. CEH sent notices to both companies informing them that their products must be printed with health warnings disclosing the presence of arsenic under California’s consumer protection law Proposition 65.

Arsenic is safe, and often unavoidable, in very small amounts, but in high concentrations it can be harmful. Drinking water with unsafe levels of arsenic can lead to cancer, reproductive problems, and developmental issues in children.

An earlier report released by Consumer Reports in April found that the same brands analyzed by CEH had twice the federal limit of arsenic in their bottled water. Keurig Dr Pepper stopped production of its Peñafiel water, which is sold at Target, Walmart, and elsewhere, for two weeks following Consumer Reports's tests. Starkey water bottles are sold at Whole Foods.

Even if they meet safety standards, many popular water brands contain trace amounts of arsenic. Consumer Reports has found acceptably low arsenic levels in Aquafina, Dasani, Evian, Deer Park, Fiji, and Poland Spring products.

These ASMR-Ready Headphones Promise to Lull You to Sleep

What do hushed whispers, gently tapping fingernails, and Bob Ross’s voice have in common? They’re all examples of triggers that may cause what’s known as an autonomous sensory meridian response (ASMR), or, as Dictionary.com succinctly explains it, a “calming, pleasurable feeling often accompanied by a tingling sensation” that can be triggered by soothing stimuli. ASMR has recently been recognized as an effective relaxation technique for those looking to calm their nerves; now, ASMR enthusiasts and novices alike can experience it in the form of a sleep-ready headband.

Upon first glance, SleepPhones: ASMR Edition may look like just a fabric headband, but the device actually features flat speakers tucked into soft, stretchy, eco-friendly material. Unlike regular headphones, SleepPhones can be worn comfortably to bed, even if you sleep on your side, and they come preloaded with content designed to help you relax. They feature eight hours of built-in ASMR content by 16 different ASMR artists (or ASMRtists), including but not limited to tracks with rhythmic tapping and "peaceful Italian whisperings."

Using SleepPhones is designed to be a stress-free experience. The speakers have the ability to play for 20 ad-free hours with a mere three-hour charging time in between. There are also zero cords involved, meaning you won’t get all tangled up as you lie down or if you have a tendency to toss and turn at night. The small button located in the back of the headband allows you to start, pause, or skip tracks and control the volume.

For people looking for ways to relax beyond yoga and meditation, ASMR may be the way to go. One study observed that subjects watching ASMR videos not only reported feeling that aforementioned pleasant tingling, but were also found to have reduced heart rates.

You can get a pair of your own SleepPhones on Kickstarter with a pledge of $75 or more. They come in three different sizes with seven colors from which to choose.
