Many of the students in my first aid classes, either just first aid, or first aid included in lifeguard training, have had “facts” they were sure about on how to give first aid, or how injuries occur, that are totally untrue.
Each professional rescuer has a standard of care to follow (from their textbook and/or in-service training) or they can be negligent, and even non-professionals who voluntarily give care should follow their training and not fall for myths-that-sound-so-plausible they heard about outside of their training.
Here are some of the common fallacies:
1) You should use aloe cream on burns. (not true)
U.C. Berkeley Wellness talked about the lack of research on aloe, and says: “Nearly all commercial aloe creams and lotions actually contain so little pure aloe that they couldn’t have much effect (they are simply moisturizers). Some contain other chemicals of questionable usefulness. Even if you use pure aloe, there are more than 300 species, with different chemical compositions and thus possibly different effects.”
2) You should clean wounds with hydrogen peroxide to prevent infection. (not true)
U.C. Berkeley Wellness said:
“If possible, hold it under cool running water. According to Larry Weiss, M.D., professor of emergency medicine at the University of Maryland School of Medicine in Baltimore, “the only thing proven to prevent infection is irrigation.” Use soap on the surrounding skin, but not on the wound itself. If you see dirt particles, remove them with tweezers.”
“Experts disagree about antibiotic creams. Some people (especially parents) would not be without bacitracin, neomycin or a similar ointment. These cause skin irritation, however, and are unnecessary if you cleanse the wound and keep it clean. Harsh antiseptics such as rubbing alcohol, iodine, hexylresorcinol and hydrogen peroxide are not only unnecessary but can actually damage skin and retard healing.”
Plus, these are painful when applied!
Just because a commercial first aid kit at the hotel pool has iodine swabs in it does not mean they are a good idea to use:
3) Crazy glue can be used to seal up a wound and prevent further bleeding. WRONG
The manufacturer says “Krazy Glue products should not be used for wound care.”
In surgery doctors sometimes use a substance to seal wounds that functions like Krazy Glue. But in surgery everything is clean and there is little chance of infection. If a lay person uses glue on a wound, they are often sealing in germs and serious, even life threatening infections can occur. Some people recommend using it on your dog, but again, you risk serious infection.
U.C. Berkeley Wellness warns: “Lots can go wrong if you try to glue a wound. Unless the glue is precisely applied, the edges of the wound may not close up and/or the glue can migrate into the wound, which can result in inflammation and infection and may require surgical treatment.”
4) Use tweezers to remove bee stingers or jellyfish tentacles. Wrong, this may cause them to inject more venom.
5) To remove a tick, apply fingernail polish, alcohol, a hot match, petroleum jelly, lotions or other potions.
NO, they do not work and they increase the risk that the tick will salivate or regurgitate into you and increase infection. Do what your Red Cross text says.
6) If someone is having a seizure, you need to put something between their teeth. NO, that is not needed and can be dangerous to the victim and to you.
And, no, people do not ever swallow their tongue, so you don’t need, as I heard once from a colleague, to use dental floss to tie a piercing on their tongue to a piercing on their lip.
When people go unconscious their muscles relax, and especially if they are lying on their back, their tongue can block their airway (breathing tube), but they never swallow it. (Yes, the De Anza College first aid class teaches what to do.)
7) Cough if you feel a heart attack coming on. NO.
U.C. Berkeley Wellness calls this “a prime example of much of the health advice you’ll find on the Internet: mostly bogus but containing a shard of truth . . . wishful thinking, disavowed by Rochester General Hospital — to which the advice is sometimes attributed — as well as the American Red Cross and American Heart Association.”
8) Most cases when first aid (or more) is needed can’t be prevented. Not true
Statistically, most of the ways we injure ourselves CAN be prevented.
Study after study tell us that prevention of injuries is possible.
– Wearing a seatbelt won’t keep you out of an accident, but you are more likely to survive it.
“Seat belt use is one of the most effective ways to save lives and reduce injuries in crashes. Yet millions do not buckle up on every trip.”
– Wearing a bike helmet won’t keep you out of an accident, but according to a report in the American Journal of Surgery, riders with helmets were less likely to die from their injuries, and less likely to break facial bones, and have 52 percent lower risk of severe traumatic brain injury. Unfortunately, less than half of the millions of Americans who ride bicycles wear bicycle helmets. Those who do wear them are more likely to be white, female and insured. (In Australia, Finland, New Zealand, Dubai, parts of Canada and many other places, bicycle helmets are mandatory in all states and territories for all ages.)
Yosemite Search and Rescue would like to remind you: “California law requires riders under 18 to wear helmets. Helmets are optional for bicycle riders 18 and over but they are an outstanding idea, inexpensive, and in many cases are the difference between a minor headache and life-altering or life-ending injuries. Unfortunately, when one observes bicycle operations in the Valley, the majority of adult bike riders, and even some children, opt to skip the helmet. Once the crash occurs, it’s too late to reconsider your decision to skip the helmet.”
– Wearing a lifejacket won’t keep you from having a boating or rafting accident, but it can save your life. Unfortunately, most people who drown in boating accidents had lifejackets on board the craft, they just were not wearing them. Why you should wear a lifejacket
– Locking up poisons and prescriptions away from kids, keeping non-swimmer kids in shallow water AND within arm’s reach, as well as making sure they can’t drown in a toilet or bucket of cleaning solution seems simple enough, but children die every year from preventable poisonings and drownings.
– Preparing for a natural disaster will likely take less time and cost less than trying to deal with it afterwards.

– About every 51 minutes, someone is killed in a drunk driving crash, many others injured. Buzzed driving is drunk driving. Buzzed horseback riding is drunk horseback riding. Buzzed surfing is drunk surfing. Buzzed skiing is drunk skiing.
“Not only can a single drink impair driving skills and slow reaction times, but it also makes it more likely that drivers will speed and not wear seat belts.”
“About one-half of all fatal traffic crashes among 18 to 24 year olds involve alcohol.” First Aider’s Guide to Alcohol from Princeton University has first aid for alcohol and alcohol myths, including, no, you can’t sober up quickly if you have to.
– Please don’t wear flipflops, high heels, platform shoes to drive.
9) Being out in the wilderness is inherently dangerous and causes more injuries. Not true
The climbing rangers in Wyoming’s Grand Teton National Park have found that less than 1 percent of backcountry accidents are due to natural causes, like falling rocks, avalanches, and animal attacks. The rest are due to ‘pilot error.’ In other words, people don’t die from unexpected snowstorms; they die from not expecting and preparing for unexpected snowstorms.
A Western Journal of Medicine article on injuries in the wilderness in California said:
“Contrary to popular belief and media attention . . . most wilderness injuries in California are not due to exotic causes, (wild animal attacks, rock climbing, hang gliding and so on). Rather they are due to common activities, such as hiking, walking, skiing and driving. Fighting and substance abuse, for example, account for more than three times as many injuries as rock climbing. . .
Search and Rescue agencies in all national and state parks / forests have had to rescue many people who should not have put themselves into a predicament. People don’t carry the headlamp / flashlight (electric torch) they really need, instead counting on their cell phone to function long enough and bright enough after dark (it won’t). They ignore warning signs, climb over barriers meant to protect them (and as a result slide over waterfalls in Yosemite), hike past trail closure signs, drink water from streams and lakes without purifying it and even wear shoes with the tread worn off them (or, yes, really, flip-flops with no ankle support or scrambling barefoot off-trail).
Some have needed to be rescued when they failed to include salty snacks in their diet, hiked a lot, got very hot and sweated a lot (sweating is your body’s number one way to to cool down), then could no longer sweat because they did not have enough salt to produce sweat, and were unable to even walk, and were starting to die from the heat. Lack of salty foods can be as dangerous as dehydration. “Easily digestible salty snacks to replenish what you lose through sweat” are recommended at the hike preparation checklist at:
People fly drones over a herd of animals, endangering themselves and others. Use of drones is illegal in National Parks. Please try to get the vehicle license number (and if possible make, model and color) / campsite number of anyone using a drone and report them to Rangers. (Do not talk to them.) If you have cell phone coverage, call park dispatch. The phone number for dispatch is usually in the park newspaper you receive when you enter the park. (When people fly drones around forest fires, the helicopters with firefighters and tankers with sprays to put out the fire can’t fly! Your photography with a drone can put human lives and property in danger.)
