Too Hot To Handle: Hot-Weather Tips For People With Asthma And Other Respiratory Conditions

Here are a few tips for staying hydrated, cool and breathing easy, especially if you don't have air conditioning:

1) Use your quick-relief inhaler at the FIRST sign of symptoms. If you're not breathing well within 30 minutes after use,
follow your written asthma action plan or call your physician for further instructions - but don't wait until symptoms
become life-threatening. That's risky business, particularly in this heat.

2) Drink LOTS and LOTS of water or sports drinks to replenish electrolytes, or blend whole fruit into one of these easy-breezy waterlogged thirst quenchers (hint: the name is the recipe!): Watermelon on Ice with a Lime Wedge, Pineapple Honeydew Drencher, Peach Puzzler with Bing Cherry Floaters... or try some iced coffee.

3) If you must sit outside to watch the children playing, soak your tootsies in a basin or tub of ice water.

4) Drench a dishtowel in ice water and sling it around the back of your neck. Repeat often.

5) Go see a funny movie at the theater!

6) Go to the grocery store and stand in the frozen-food section as long as possible during the heat of the day!

7) When watering your garden, squirt yourself with the hose. So what if the neighbors are watching?

8) Mind over matter: Convince yourself that it's snowing outside and you just ate a hot bowl of chili.
<<<Think cool.

9) If you don't need it plugged in, unplug it. You'd be surprised how many of our gadgets give off heat.

10) And if the air conditioning isn't working at the office - GO HOME! Working under unhealthy conditions is,
well, not healthy.

It can take only 48 hours of uninterrupted exposure to intense heat before the body’s defenses begin to break down. The longer a heat wave continues the more susceptible the body becomes to illness. Just a few hours of relief can break the cycle, which is why increased temperatures at night are so dangerous and why air conditioning is a life saver. Heat illness results from dehydration at high
temperatures. Dehydration causes the sweating mechanism to fail, eliminating the body’s natural cooling system. Body temperature may rise to 106 or higher in just 10 to 15 minutes.
Heat stroke begins when people start to develop an altered level of consciousness, usually when their temperature rises above 105. Then the body starts to cook.
First the brain cells die.  Then the liver cells go. Fluid spills out into the lungs.

If the body remains in the heat, the result can be coma and, finally, death.

For those of you dealing with the sweltering heat, the CDC has a good  write-up (.pdf) on how to protect yourself and prevent illness.

Genetic ancestry data improve diagnosis in asthma and lung disease
