Record Breaking Heat Wave Sears the Country – And its Not Letting Up Anytime Soon

Summer- a time of long, endless days of warm weather that children across the country look forward to when school lets out. Swimming, hiking, bicycling, and even setting up camp and stargazing in the backyard are the stuff that fond memories are made of.

All these fun activities, however, can pose potential illness or danger, especially when its hot outside.

Heat wave sweeps the country

Record breaking heat was recorded in Miami, Austin and Phoenix over the past few days. Even Portland Oregon, usually known for its cooler weather broke daily records.  You don’t have to have record breaking weather to suffer overexposure to sun and heat. One recent and very heartbreaking story  out of Vancouver was of a one-year-old child that died from heat stroke in a car while the outdoor temperature was only 70-75 degrees. The inside of the car reached 110 degrees.  According to the National Safety Council on average more than 38 children from the ages of 1-15 die from heatstroke, mostly from being in a hot car. July is the month that most of these deaths occur, according to the website.

That quick trip into the store for a quart of milk could prove dangerous, even fatal to a young child left unattended in a vehicle.

Populations most at risk for heat related illnesses
Heat related illnesses can affect anyone but certain populations are more prone than others. These include:

Age: Infants, young children, and elderly individuals are more susceptible to heat related illnesses. Both children and elderly have a reduced ability to regulate body temperature.

High heat exposure: High temperatures for extended periods, especially during a heat wave, can put anyone at risk for heat related illness.

High humidity: When the humidity is high, the body’s ability to cool down through sweating is reduced, increasing the risk of heat-related illnesses, including heat stroke.

Chronic health conditions: Certain medical conditions, such as heart disease, lung disease, obesity, and diabetes, can reduce the body’s ability to handle heat stress, making individuals more susceptible to heat stroke.

Medications: Some medications can interfere with the body’s ability to regulate temperature, leading to heat exhaustion or heat stroke. Take precautions if on any medications. The following is a brief list- check your specific medication for more information:

Anticholinergic drugs: These medications block the action of acetylcholine, a neurotransmitter that plays a role in various bodily functions, including sweating. By reducing sweating, these drugs can hinder the body’s ability to cool down effectively. Examples include certain antihistamines, tricyclic antidepressants, and medications for overactive bladder.

Diuretics: Diuretics, commonly known as water pills, increase urine production, which can lead to dehydration. Dehydration impairs the body’s ability to regulate temperature, making it harder to dissipate heat. Some diuretics cause electrolyte imbalances which can further compromise health.

Beta-blockers: Beta-blockers are used to treat various conditions, including high blood pressure and heart conditions. They can reduce the heart rate and limit the body’s response to heat, potentially interfering with temperature regulation.

Psychotropic medications: Certain medications used to treat mental health conditions, such as antipsychotics and mood stabilizers, can affect the body’s heat regulation mechanisms, leading to increased heat sensitivity. This is an often-overlooked class of drugs. Be sure to check with pharmacist or read side effects of these drugs before heading off into the heat.

Antidepressants: Some antidepressants, especially those that affect serotonin levels, can impact the body’s thermoregulatory systems, potentially causing an increased risk of heat-related issues.

Antihypertensive medications: Some medications used to lower blood pressure, such as alpha-blockers, can impact the body’s response to heat and affect blood flow to the skin.

Alcohol and drug use: Alcohol and certain drugs can impair the body’s ability to regulate temperature and increase the risk of heat stroke.

Physical activity:  Physical activity, particularly in hot and humid conditions, can raise the risk of heat stroke, especially if adequate hydration is not maintained. If not acclimated to the heat this can pose a serious health risk.

Lack of acclimatization: Individuals who are not accustomed to hot weather or are not acclimatized to the heat may be more susceptible to heat stroke. This is especially true for those living in or working in air-conditioned buildings.

Heat exhaustion and heat stroke- know the signs and what to do

Heat exhaustion and heat stroke are two distinct heat-related illnesses, with heat stroke being the more severe condition.

CDC excerpt on heat exhaustion and heat stroke:

Avoid

When the temperature is very high stay indoors. If you must go outside, dress properly and take breaks often. Know who is at high risk for heat stroke and heat exhaustion.

Tips to Beat the Heat

  • Drink plenty of water! (I will add that electrolyte drinks such as these can replace lost fluids and prevent electrolyte imbalance
  • Check on friends and neighbors at high risk for heat-related illness
  • Find airconditioned places to cool off (shopping malls and libraries)
  • NEVER leave kids or pets in a closed, parked vehicle
  • If you go outside, remember:
    • A hat
    • Sunscreen (spf 15 or higher)
    • Lightweight, light-colored, loose-fitting clothing
    • Water
    • Limit time outdoors. Take breaks often
  • Know who is at high risk:
    • Infants
    • Young children
    • Older adults
    • People with chronic medical conditions

Spot

Know the signs of heat stroke and heat exhaustion.

Heat Stroke

Signs & Symptoms

  • Very high body temperature (above 103°F)
  • Red, hot, and dry skin (no sweating)
  • Rapid, strong pulse
  • Throbbing headache
  • Dizziness
  • Upset stomach
  • Confusion
  • Passing out

Heat Exhaustion

Signs & Symptoms

  • Heavy sweating
  • Paleness
  • Muscle cramps
  • Tiredness
  • Weakness
  • Dizziness
  • Headache
  • Upset stomach or vomiting
  • Fainting

If you see any of these signs, get medical help immediately.

Treat

While waiting for medical attention, you can help someone with heat stroke or heat exhaustion.

Heat Stroke

Move the victim to a shady area or indoors. Do not give the person fluids.

Cool the body by:

  • Placing person in a cool (not cold) bath or shower
  • Spraying with a garden hose
  • Sponging with cool water
  • Fanning

Continue efforts to cool the person until help arrives or his or her body temperature falls below 102°F and stays there.

Heat Exhaustion

Get medical attention if symptoms get worse or last longer than one hour.

Cool the body with:

  • Cool, nonalcoholic beverages
  • Rest
  • A cool (not cold) bath, shower, or sponge bath
  • Moving to an airconditioned room
  • Wearing lightweight clothing

Seek medical help immediately if symptoms are severe or if victim has heat problems or high blood pressure.

Taking just a few precautions will ensure you and your child will have a fun and adventure filled summer.

Planning a Trip This Summer? Don’t forget your Portable Medical Kit!

Whether planning an extended vacation or a last-minute weekend getaway, emergencies can happen anytime and anywhere. A portable, grab and go kit that carries not just basic first aid supplies but things you may need to prevent or manage minor illnesses can keep you and your family from having to interrupt your plans by seeking medical attention.

Depending on where you are headed- the great outdoors or jetting out of town, there are always a few things that traveling anywhere has in common.

  1. Your schedule is different, so your immunity is lower. Even if you plan your trip around your awake/asleep cycle, the very fact you are traveling makes life stressful. Stress doesn’t necessarily have to be a negative event. Even “good” stress can compromise health- Negotiating travel- whether by car or plane can be stressful. The end goal may be geared toward a fun filled vacation, but getting there may not be. Our immune system isn’t too happy with us when we are stressed and tends to not be as strong. Strange water, food, schedules and new areas traveled can set us up for illnesses we normally would shake off. For instance, you pull into a roadside restaurant (or airport food court) for a quick bite. You eat and leave, not knowing that the food wasn’t thoroughly cooked (rush hour). Several hours later, diarrhea, vomiting and low grade fever hit. These are classic signs of salmonella poisoning (from contaminated food). When functioning properly, the stomach has natural defenses against salmonella poisoning. The high acid content kills the bacteria. However, when our regular diet and routine are interrupted, we can succumb to illnesses that normally wouldn’t affect us.

 If able, have a cooler full of foods you normally eat to snack on your trip. Try not to eat out if possible. If traveling by plane, purchase bottled water, avoid drinking faucets (dangerous bacteria has been found in drinking fountain water) Bring extra food in case plane is delayed.

2. Heat and travel don’t mix- Be sure to keep plenty of water and electrolyte mix on hand . Dehydration is a very serious condition, leading to kidney failure and death. If you are traveling in an area known to be hot (even if it isn’t) be sure to pack electrolyte powder in your portable medical kit. If possible, travel early in the morning before the heat of the day. Keep a water bottle filled with water for each passenger in the car. Don’t forget about pets; remember a water dish and extra food for them also. Have at least an extra gallon of water stored in addition to each person’s water bottles.

3. Take frequent breaks- if traveling by car, trade drivers. Highway hypnosis is real. The monotonous job of driving for hours can lead to falling asleep at the wheel even though you don’t realize it. Take advantage of travel rest areas. Get out and stretch your legs. If you are the sole driver and are feeling fatigued be sure to pull over and take a nap or find a hotel if it is getting late.

In addition to a standard first aid kit, a travel medical kit should be added for extended trips away from home.

This type of kit should include:

  • Extra prescription medication and any otc supplements or vitamins- at least several days more than you think you may need in case your trip home is delayed.
  • Anti diarrheal medication (Imodium or Pepto-Bismol)
  • Age appropriate fever and pain reliever for all in group) Tylenol, ibuprofen, naproxen, etc.)
  • Antihistamine for allergic reactions and seasonal allergies
  • Sunscreen (with UVA and UVB protection, SPF 15 or higher)
  • Sunburn cream or Aloe gel
  • Moist towelettes to wipe hands in case there is no clean water at rest stations or airport restrooms.
  • Electrolyte powder packs
  • Travelers’ diarrhea antibiotic (check out Jase case antibiotics if you haven’t already)
  • Diarrhea medicine (Imodium or Pepto-Bismol)
  • Antacid (Tums)
  • Motion sickness medicine (Dramamine)
  • Cough drops, cough suppressant, or expectorant
  • Mild laxative
  • Hand sanitizer (containing at least 60% alcohol) or antibacterial hand wipes
  • Water purification tablets
  • Insect repellent (with an active ingredient like DEET or picaridin) Some essential oils have proven insect repellant properties. Check out this research paper for more information.
  • Insect bite anti-itch gel or cream (calamine lotion, hydrocortisone cream)
  • Cotton swabs (Q-Tips)
  • Tweezers
  • Paper cups
