Northern Nevada is home to some of the most gorgeous and pristine lakes in the country — but also some of the most unforgiving. Lake Tahoe water temperatures average 50 degrees in the summer, making the danger of hypothermia real and always present. Here are the signs, symptoms and ways to prevent cold water drowning. When we think of air temperature at 50 degrees Fahrenheit, it’s not all that cold. But when it comes to water that’s 50 degrees, there is no comparison. Immersion in cold water is life threatening and can happen within a minute. Taking the right precautions before entering the water can save your life. The 4 Phases of Cold Water Drowning 1. Cold Shock Response: This response affects breathing and happens within the first minute. An automatic gasp reflex occurs in response to rapid skin cooling. If the head goes below water, water may be breathed into the lungs, resulting in drowning. A life jacket will help keep your head above water during this critical phase. Additionally, hyperventilation, like the gasp reflex, is a response to the cold and will subside. Panic will make this worse, so the key is to control breathing. 2. Cold Incapacitation: This response occurs within the first five to 15 minutes in cold water. In order to preserve core heat, vasoconstriction takes place decreasing blood flow to the extremities to protect the vital organs. The result is a loss of movement to hands, feet, arms and legs. Unless a life jacket is being worn, the ability to stay afloat is next to impossible. 3. Hypothermia: Important to note, it can take 30 minutes or more for most adults to become hypothermic. So there’s time to take action and survive. Keeping panic at bay is critical, as you have more survival time than you think. Symptoms include: Shivering Slow and shallow breathing Confusion Drowsiness or exhaustion Slurred speech Loss of coordination Weak pulse 4. Circum-rescue Collapse: This experience can happen just before rescue and is not well understood. Symptoms range anywhere from fainting to death. Some experts believe an abrupt drop in blood pressure may cause this final stage of cold water drowning, post-rescue. Additional Cold Water Drowning Safety Tips and Helpful Resources Always wear a personal flotation device as well as a wetsuit or drysuit. Your personal flotation device is the most important piece of water safety gear. Try not to panic as the first phases will subside. Controlled breathing is to staying calm. Research suggests the body can withstand the cold longer than we think. The Heat Escape Lessening Posture (HELP) is a position which helps conserve energy if you’re wearing a personal flotation device. By hugging your knees to your chest, this posture helps maintain body heat for some time.

When you’re too sick to go to work but not sick enough for a doctor’s visit, over-the-counter medicines are a welcome relief to help alleviate that fever, runny nose or allergies. But because those medicines aren’t signed off on or managed by your doctor and pharmacist, you must be especially mindful of what you put into your body. Whenever you pop a pill, you want to ensure you’re taking the correct dosage, waiting the right amount of time before taking another dose and not mixing certain medicines. Too Much Tylenol/Acetaminophen Tylenol — or acetaminophen — is a popular pain reliever for many, but too much can be bad for your liver. “Our bodies have a finite ability to metabolize Tylenol,” says Andy Wright, clinical pharmacist at Renown Rehabilitation Hospital. “When too much builds up in the liver, it becomes toxic. In patients with medical conditions like cirrhosis of the liver or hepatitis, this could be disastrous.” Remember, acetaminophen is in more than just Tylenol and generic pain relievers. You may also see acetaminophen in flu, cold and cough medicines, like Nyquil, and some prescription medications including Norco and Percocet. Keep a list of the medications you take, and limit daily acetaminophen use to 3,000 mg per day. When you’re scanning medicine bottle contents, remember acetaminophen is also referred to as APAP, AC, acetam or paracetamol. Mixing Painkillers When you’re dealing with pain and not getting any relief, taking a different medication may seem like the easy solution. Maybe you take some Aleve — a form of naproxen — for a headache, but it isn’t working, so you switch to Motrin, an over-the-counter form of ibuprofen. Not a smart idea. Ibuprofen and naproxen along with aspirin are known as nonsteroidal anti-inflammatory drugs (NSAIDS). Because these medicines work in similar ways, they should never be combined or used in larger doses or more frequently than directed. Otherwise your risk of side effects can increase, which range from mild nausea to severe gastrointestinal bleeding.  It’s also important to consider your family history when taking NSAIDs because, “recent studies have shown NSAIDs may have greater cardiovascular risks for people taking blood thinners or those with hypertension,” explains Andy. “A good example is ibuprofen: It has a relatively low gastrointestinal bleed risk while it has a moderate to high cardiovascular risk. The opposite is true for naproxen.” Rather than experimenting with multiple medicines, figure out which drug works best for you. You may find muscle soreness improves with aspirin, whereas when a headache hits, naproxen is best. Keep in mind that these medications aren’t always best for everyone in the family. “Aspirin in children and teens is not recommended unless under the supervision of a doctor,” Andy says. And pregnant and lactating women should generally avoid NSAIDS due to risk of birth defects and bleeding. “In both of these cases, acetaminophen or Tylenol are preferred but only if approved by an OB/GYN.” Fighting Allergies Over-the-counter antihistamines like Claritin, Zyrtec and Allegra have made fighting itchy eyes and runny noses a little easier. But these daily medicines — when taken inappropriately or in the wrong combinations — can also have an adverse effect. Similar to acetaminophen, you need to watch for antihistamines in other products. Sleep aids — like Tylenol PM and Unisom — commonly use an antihistamine known as diphenhydramine, which may increase your risk of overdose. “Combining antihistamines, or overdosing, can cause many adverse effects including dry mouth, blurred vision — even arrhythmias,” Andy says. “Only take these medications on their own.” If you’re still struggling with symptoms, you can talk to your doctor about adding an over-the-counter nasal steroid.  Andy confirms the importance of closely following the directions listed on antihistamine (and all medicine) bottles. He has seen extended release nasal decongestants cause significant arrhythmias requiring medical care after a patient took the medicine with warm fluids. “The decongestant in question is designed to slowly release, but it can dissolve suddenly in the presence of warm liquids like coffee,” Andy explains. “This can cause the pill to deliver 12 to 24 hours of medication all at once.” Taking an Antidiarrheal with Calcium Calcium supplements and antidiarrheal medicines are another harmful combination. Calcium firms up your stool, but if taken with an antidiarrheal, can cause severe constipation. If you need to take an antidiarrheal, take a break from your calcium for a few days until you’re back to normal. Another consideration when taking calcium supplements or calcium-based antacids is gas. “I’ve had several patients report cases of excessive gas using Tums or calcium carbonate-based supplements.” Andy suggests instead “trying Maalox or Mylanta for indigestion and Citracal as a supplement.” Talk with Your Doctor or Pharmacist About Your Medications If over-the-counter drugs aren’t providing the relief you need, it’s time to see your doctor. And remember, for your safety it is important to keep your doctor and pharmacist up-to-date with any medications — prescribed or over-the-counter — that you are taking.
