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.

6 Signs You're Getting Hangry

Hangry (adjective): Bad-tempered or irritable as a result of hunger. This portmanteau (of hungry and angry) is not only officially recognized as a word by the Oxford English Dictionary, but it's also recognized by health experts as a real physiological state with mood-altering consequences.

That hangry feeling results from your body's glucose level dropping, putting you into a state of hypoglycemia, or low blood sugar. Glucose is the body's primary source of energy, so when you don't have enough, it affects your brain and other bodily functions, including the production of the hormones insulin and glucagon, which help regulate blood sugar. Check out the symptoms below to see if you've crossed over into the hanger danger zone.

1. IT TAKES EVERYTHING IN YOUR POWER JUST TO KEEP YOUR EYES OPEN.

Glucose equals energy, so when your blood sugar levels are low, you may start wishing you were back in bed with the shades drawn. If you start feeling sluggish or tired even though you’re well-rested, you might just need to eat something.

2. THE EASIEST ITEM ON YOUR TO-DO LIST SEEMS LIKE AN IMPOSSIBLE TASK …

It’s hard to concentrate when all you can think about is whether you're going to order the fish or beef tacos for lunch. The distraction goes beyond fantasies about food, though. The brain derives most of its energy from glucose, so when it's low on fuel, a serious case of brain fog can set in. Confusion and difficulty speaking are among the more serious symptoms you may experience when you're hangry.

3. … AND YOU HAVE A BAD CASE OF WORD VOMIT.

Blame this on brain fog too. The gray matter in your noggin goes a little haywire when blood sugar is in short supply. That's why you may start stuttering or slurring your words. You might also have difficulty finding your words at all—it can feel like your mouth and brain are disconnected.

4. YOU’RE SHAKING LIKE A LEAF AND FEEL LIGHTHEADED.

Tremors and dizziness are both signs that you should pay closer attention to your body, which is screaming, "Feed me!" Once again, low blood sugar is often the culprit of trembling hands and feeling faint, and exhaustion and stress make the symptoms worse.

5. YOUR COWORKERS SEEM ESPECIALLY ANNOYING.

You’re tense and irritable, and it’s starting to show. Hunger causes your body to release cortisol and adrenaline, the same hormones responsible for stress. This can put you on edge and lower your tolerance for other people’s quirks and irksome habits, which suddenly seem a lot less bearable.

6. YOU SNAPPED AT YOUR FRIEND OR PARTNER FOR NO GOOD REASON.

Not only are you irritable, but you’re more likely to lash out at others because of it. The doses of adrenaline and cortisol in your body can induce a fight-or-flight response and make you go on the attack over matters that—if you had some food in you—would seem unimportant.

So what should you do if these descriptions sound all too familiar? Eat a snack, pronto—one with complex carbohydrates, lean protein, and healthy fats. The first one brings up your blood sugar level, and the other two slow down how fast the carbohydrates are absorbed, helping you to avoid a sugar crash and maintain a normal blood sugar level. Eating small meals every few hours also helps to keep hanger at bay.

You Can Now Book a Nap Nook in New York City

New York might be the city that never sleeps, but its residents need to catch some Zs every now and then—even at times when it's least convenient. As spotted by Dezeen, mattress maker Casper has come up with a clever solution for those moments when you simply can't keep your eyes open at work: rentable nap pods.

At The Dreamery, the company's mattress-filled downtown Manhattan facility, snooze sessions in your own private nook can be booked on Casper's website or on a walk-in basis. The $25 fee will get you a pair of constellation-print pajamas, 45 minutes of downtime in a circular sleep pod, refreshments, and skin care products.

One of the common concerns is hygiene, and it's something that Casper has addressed in its FAQ section. According to the company, all of the bedding is stripped and laundered in between nap sessions, "and constant airflow will keep the space feeling and smelling fresher than a hotel room."

Each pod is outfitted with auto-fading lights, a reading light, a sound-absorbing back wall, and a bedside shelf with outlets. Casper also collaborated with Headspace, a company specializing in daily mindfulness exercises, to provide a selection of "sleepcasts" that take listeners on guided meditations of a deep sea submarine expedition or a walk through a surreal landscape.

The lights gradually turn back on at the end of the session, and patrons can freshen up in The Dreamery's lounge with a cup of coffee before heading back to the office or out for a day of sightseeing.

"The Dreamery is about making sleep and rest a part of our regular wellness routines—similar to how many people prioritize a workout class," Neil Parikh, Casper's co-founder and COO, said in a statement.

Located at 196 Mercer Street in SoHo, The Dreamery is ideal for employees in Lower Manhattan who could use a quick catnap between meetings or for visitors who have a jam-packed tourist itinerary, and it stays open fairly late—up to 8 p.m. Monday through Saturday, and 6 p.m. on Sundays.
