Summer heat related illness--heat stroke

Heat Stroke occurs when the person goes past heat exhaustion and his body loses the ability to cool itself and overheats.  Heat stroke is very dangerous.  The person no long can sweat to cool and his body temperature rises to dangerous levels (up to 106) quickly (within 10-15 minutes). 

Symptoms of heat stroke:  may be profuse sweating which probably decreases and the person’s body becomes hot and dry, the person may hallucinate, become confused and/or dizzy,  may slur his speech.  The person may have a major throbbing headache and he may deal with chills while his body temperature climbs.

Heat stroke is the most serious heat illness and requires quick treatment:  call 911 for help.  While emergency help is coming, move the person to a cool shaded area and cool the person my applying cool water to him and his clothes.  More information about heat illnesses can be found at http://www.cdc.gov/niosh/topics/heatstress/

Summer time--heat exhaustion

Summer heat can make us ill.  What’s the difference between heat exhaustion and heat stroke?           

Heat exhaustion occurs when a person loses too much body fluids (both water and salt) through sweating.  Heat exhaustion can affect anyone out in the heat and humidity.  Some health factors increase a person’s risk of heat exhaustion:  being elderly, working in a hot environment and having high blood pressure.

Symptoms of heat exhaustion:  sweating heavily, feeling weak and exhausted, becoming confused and dizzy, feeling nauseated, having clammy, moist skin, a pale or flushed appearance, muscle cramps, fast and shallow breathing.  As the person becomes heat exhausted, his body temperature may rise. 

Treatment for heat exhaustion includes having the person “rest in a cool, shaded or air-conditioned area…drink plenty of water or other cool, nonalcoholic beverages…and take a cool shower, bath or sponge bath.”  CDC.gov, Heat Stress, http://www.cdc.gov/niosh/topics/heatstress/

Summer heat related illness--how to protect those at risk

Summer continues its relentless heat.  How can we protect those at risk?

Remember to watch out for people who are at risk for heat-illness:  children, the elderly, people with chronic medical conditions (and pets).  They should never be left in cars.   The interior of a vehicle can heat up very quickly when the sun is shining on it.  For example, interior temperatures of a car with windows cracked open can raise almost 20^oF in the first 10 minutes.  The CDC gives this good suggestion:  “to remind yourself that a child is in the car, keep a stuffed animal in the car seat.  When the child is buckled in, place the stuffed animal in the front with the driver.  When leaving your car, check to be sure everyone is out of the car.  Do not overlook any children who have fallen asleep in the car.”   More information can be found at http://www.bt.cdc.gov/disasters/extremeheat/heat_guide.asp

Summer heat related illness

Summer hit us early and continues at full blast.  Are you protecting yourself and your loved ones from the dehydration and serious heat related illnesses. 

The Centers for Disease Control (CDC) gives this information:  “Getting too hot can make you sick…Heat exposure can even kill you; it caused 8015 deaths in the United States from 1979 to 2003.” How does a person keep cool when working in the hot weather?  

If possible, stay in an air conditioned environment.  Steps you can take to protect yourself from becoming overheated includes drinking plenty of liquids (non-caffeine and non-alcoholic are best fluid replacements), replacing salt and minerals (sports drinks replace salt and minerals we lose when sweating), and pacing yourself (take breaks in a cooler environment if possible).  People who work out in the weather need to protect their skin by using sunscreen and light-weight, light-colored and loose-fitting clothing including a wide-brimmed hat.  You see many construction workers starting very early in the morning so their day ends before the hottest heat and highest humidity. If possible, have a buddy working with you during the heat and watch out for each other’s health.  For more information, http://www.cdc.gov/Features/ExtremeHeat/?source=govdelivery

Tips to Prevent Traveler's Diarrhea

We knew the water available to us in Alaska and Canada would be safe to drink.  We had no problems.  However, there are many countries in the world that do not have clean, safe tap water to drink. 
If you are traveling to a country where clean water isn’t available, what can you do to protect yourself from traveler’s diarrhea?  Avoid tap water for brushing your teeth and drinking.  (I found it helpful to hold bottled water in one hand while I was brushing my teeth.  By doing so, I could not automatically  turn on the faucet and rinse my toothbrush in unclean water.  That’s such a habit.)  Don’t use ice unless you know it’s made from purified water.  Check that the bottled water seal is intact (not refilled with questionable water.)  Look for “pasteurized” milk and dairy products including ice cream.  Pasteurized dairy products should be safe as it’s been heated to kill germs.  Avoid fresh salads with leafy vegetables.  Be suspicious of all fresh fruits and vegetables which you can’t peel.  Don’t eat raw or half-cooked (rare) meat and seafood.  Don’t buy food from street vendors.  More information can be found at Health Day.com, http://consumer.healthday.com/Article.asp?AID=665759

A good reason to travel

 “Every now and then go away, have a little relaxation, for when you come back to your work your judgment will be surer.  Go some distance away because then the work appears smaller and more of it can be taken in at a glance and a lack of harmony and proportion is more readily seen.”  Leonardo Da Vinci, AKlein, The Simplify-Your-Life Quote Book, (New York: Gramercy Books, 2005), 127.
