PTSD Might Be Contagious

Traumatic events don’t just affect the people who experience them. They also affect the victim’s partner, parents, children, and friends. We know this intuitively, but Scientific American highlights new research showing that the impact of trauma goes even deeper: Post-traumatic stress disorder (PTSD) might be passed from person to person.

By describing the traumatic event to another person, a form of secondary PTSD can be "caught" by someone who is close to the trauma victim, such as a parent, spouse, or even a therapist or emergency responder. According to Scientific American, recent research suggests that 10 to 20 percent of people who have a close relationship with someone who has PTSD could develop the condition themselves. One study from 2013 found that nearly one in five healthcare workers who had been helping members of the military with PTSD had developed “secondary trauma” [PDF].

Some of the symptoms they experienced included intrusions, or mental images, flashbacks, or nightmares of the traumatic event. Other symptoms were sleep disorders, feelings of hopelessness, stress-induced hyperarousal, and an overreactive fight-or-flight response.

Similar studies revealed that emergency responders, social workers, trauma therapists, and the wives of former prisoners of war are also at risk. Although the spouses or partners of war veterans are often affected, research from 2017 showed that the parents of veterans seemed unaffected, while the children of veterans occasionally showed symptoms, but not severe ones.

The definition of the disorder has even been amended to reflect these findings. According to the updated Diagnostic and Statistical Manual of Mental Disorders, firsthand experience of a traumatic incident isn’t necessary to be diagnosed with PTSD.

Psychologist Judith Daniels of the University of Groningen in the Netherlands suggests there’s a physiological explanation for why secondhand trauma can seem so real and vivid to someone who never experienced the trauma itself directly. “The regions of the brain that proce[ss] visual imagery have a very strong overlap with regions that process imagined visual experience,” she tells Scientific American. It would seem that just hearing about the traumatic event is enough to produce PTSD-like symptoms.

Researchers also found that extremely empathetic people and people who don’t keep any “emotional distance” from the trauma victim (such as spouses) are at greater risk of developing secondary PTSD. That’s partly because they may internalize the trauma.

There may also be a genetic aspect that allows PTSD to be passed down from parent to child. A 2017 study suggests that one’s genetic biomarkers could denote a higher risk of PTSD, but researchers said further studies are needed to identify the specific genes involved, CNN reports.

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.
