What’s on your mind this weekend, Bleeding Heartland readers? It finally got warm enough to go swimming in Iowa, so I wanted to re-post this link on recognizing the signs of drowning. A few excerpts from the article are after the jump. A person in trouble in the water looks nothing like common depictions on television or in movies.
The Environmental Working Group’s latest guide to sunscreens is the best resources for finding effective sun protection with minimal harmful chemicals. Other good links on that site: Nine Surprising Facts About Sunscreen, why it’s better to avoid sunscreens containing vitamin A, and why marketing of sunscreens with SPF above 50 is misleading.
A recent report by AAA and experts from the University of Utah again confirmed that hands-free cell phones are not safe to use while driving. The DC Streets blog posted a good summary of the findings. The full report is here (pdf), and you can download a fact sheet here (pdf). I’ve posted excerpts from the AAA study after the jump. Earlier research reached similar conclusions (pdf) about distracted driving, one of the leading causes of fatal car accidents. Pull over when you need to make or answer a call. Even if both hands are on the wheel, a cellphone conversation can lead to “inattention blindness.” Many people wrongly believe it’s safe to send voice-activated texts while driving, texting while driving is extremely dangerous as well as illegal in Iowa.
If you saw the moon Saturday night or early Sunday morning, you witnessed the largest full moon of the year.
UPDATE: The wet weather has ushered in a banner year for mosquitoes, but it’s safer to protect yourself with DEET-free products. Also, watch out for poison ivy if you are out and about. It’s prevalent along recreational trails.
Excerpt from Drowning doesn’t look like drowning by Mario Vittone:
1. “Except in rare circumstances, drowning people are physiologically unable to call out for help. The respiratory system was designed for breathing. Speech is the secondary or overlaid function. Breathing must be fulfilled before speech occurs.
2. Drowning people’s mouths alternately sink below and reappear above the surface of the water. The mouths of drowning people are not above the surface of the water long enough for them to exhale, inhale, and call out for help. When the drowning people’s mouths are above the surface, they exhale and inhale quickly as their mouths start to sink below the surface of the water.
3. Drowning people cannot wave for help. Nature instinctively forces them to extend their arms laterally and press down on the water’s surface. Pressing down on the surface of the water permits drowning people to leverage their bodies so they can lift their mouths out of the water to breathe.
4. Throughout the Instinctive Drowning Response, drowning people cannot voluntarily control their arm movements. Physiologically, drowning people who are struggling on the surface of the water cannot stop drowning and perform voluntary movements such as waving for help, moving toward a rescuer, or reaching out for a piece of rescue equipment.
5. From beginning to end of the Instinctive Drowning Response people’s bodies remain upright in the water, with no evidence of a supporting kick. Unless rescued by a trained lifeguard, these drowning people can only struggle on the surface of the water from 20 to 60 seconds before submersion occurs.”
News release Think You Know All About Distracted Driving? Think Again, Says AAA (more links are on the page in the “additional resources” box):
New research reveals that voice-activated in-car technologies dangerously undermine driver attention
WASHINGTON, D.C., (June 12, 2013)-Hands-free technologies might make it easier for motorists to text, talk on the phone, or even use Facebook while they drive, but new findings from the AAA Foundation for Traffic Safety show dangerous mental distractions exist even when drivers keep their hands on the wheel and their eyes on the road. The research found that as mental workload and distractions increase reaction time slows, brain function is compromised, drivers scan the road less and miss visual cues, potentially resulting in drivers not seeing items right in front of them including stop signs and pedestrians. This is the most comprehensive study of its kind to look at the mental distraction of drivers and arms AAA with evidence to appeal to the public to not use these voice-to-text features while their vehicle is in motion.
With a predicted five-fold increase in infotainment systems in new vehicles by 2018, AAA is calling for action as result of this landmark research. “There is a looming public safety crisis ahead with the future proliferation of these in-vehicle technologies,” said AAA President and CEO Robert L. Darbelnet. “It’s time to consider limiting new and potentially dangerous mental distractions built into cars, particularly with the common public misperception that hands-free means risk-free.”
Cognitive distraction expert Dr. David Strayer and his research team at the University of Utah measured brainwaves, eye movement and other metrics to assess what happens to drivers’ mental workload when they attempt to do multiple things at once, building upon decades of research in the aerospace and automotive industries. The research included:
Cameras mounted inside an instrumented car to track eye and head movement of drivers.
A Detection-Response-Task device known as the “DRT” was used to record driver reaction time in response to triggers of red and green lights added to their field of vision.
A special electroencephalographic (EEG)-configured skull cap was used to chart participants’ brain activity so that researchers could determine mental workload.
Using established research protocols borrowed from aviation psychology and a variety of performance metrics, drivers engaged in common tasks, from listening to an audio book or talking on the phone to listening and responding to voice-activated emails while behind the wheel. Researchers used the results to rate the levels of mental distraction drivers experienced while performing each of the tasks. Similar to the Saffir-Simpson scale used for hurricanes, the levels of mental distraction are represented on a scale:
Tasks such as listening to the radio ranked as a category “1” level of distraction or a minimal risk.
Talking on a cell-phone, both handheld and hands-free, resulted in a “2” or a moderate risk.
Listening and responding to in-vehicle, voice-activated email features increased mental workload and distraction levels of the drivers to a “3” rating or one of extensive risk.
“These findings reinforce previous research that hands-free is not risk-free,” said AAA Foundation President and CEO Peter Kissinger. “Increased mental workload and cognitive distractions can lead to a type of tunnel vision or inattention blindness where motorists don’t see potential hazards right in front of them.” Based on this research, AAA urges the automotive and electronics industries to join us in exploring:
Limiting use of voice-activated technology to core driving-related activities such as climate control, windshield wipers and cruise control, and to ensure these applications do not lead to increased safety risk due to mental distraction while the car is moving.
Disabling certain functionalities of voice-to-text technologies such as using social media or interacting with e-mail and text messages so that they are inoperable while the vehicle is in motion.
Educating vehicle owners and mobile device users about the responsible use and safety risks for in-vehicle technologies.
AAA also is using the findings to promote dialogue with policy makers, safety advocates and industry to ensure that these emerging in-vehicle technologies won’t lead to unintentional compromises in public safety. As part of this effort, AAA has already met with safety advocates and provided copies of the report to CEOs of all major U.S. automakers.
“This study constitutes the most in-depth analysis to date of mental distractions behind the wheel. AAA is hopeful that it will serve as a stepping stone toward working in collaboration with automakers to promote our shared goal of improving safety for all drivers,” said Darbelnet. “Specifically, these increasingly common voice-driven, in-vehicle technologies should be limited to use for just core driving tasks unless the activity results in no significant driver distraction.”

Established by AAA in 1947, the AAA Foundation for Traffic Safety is a 501(c) (3) not-for-profit, publicly-supported charitable educational and research organization. Dedicated to saving lives and reducing injuries on our roads, the Foundation’s mission is to prevent crashes and save lives through research and education about traffic safety. The Foundation has funded over 200 research projects designed to discover the causes of traffic crashes, prevent them, and minimize injuries when they do occur.
