A HEAT WAVE: WHAT WORKS AND WHAT DOESN’T
- A heat wave: should we drink warm or cold liquids?
In the East, they drink green tea on one side and ayran on the other. One theory says
that heating yourself from the inside causes you to sweat. This cools you.
Another opinion intuitively advises to avoid warm liquid. They
say it’s dehydrating.
If you believe the research, though, warm is better, but only if the humidity outside is low!
- Is using a fan good or bad?
Yes, everyone knows that it only pushes the air around. But science says that fans are only good if the temperature is below 95’. otherwise, it makes it worse.
It’s the same with humidity. If humidity is high, then a fan makes it worse.
There are no clear studies, but 10 out of the 17 people that died in the 1999 Cincinnati heat wave were using fans. It’s not improbable, however, that death would have come sooner without the fans.
I’d like to take this opportunity to thank my personal fan at home; it has served me for over 20 years. They don’t make them like that anymore.
- Is heat dangerous for the elderly?
Thermoregulation requires that the heart operate at full blast, so the elderly are at risk for cardiac events. And unlike the cold, heat can kill a person during the first 24 hours.
Furthermore, the elderly don’t always realize when they’re overheated or dehydrated.
This doesn’t mean that it’s more dangerous for the elderly, though. It’s hostile to people of all ages and can be fatal for pets, as well.
- Should we open the windows?
Only when it’s cooler outside than inside.
During peak temperatures, windows should be closed with curtains drawn. Otherwise, the draft will exacerbate things.
BEER AND WATER IN THE HEAT
- Can beer save you?
In an experiment in Spain, participants ran for 40 minutes on a treadmill. Both beer and water helped to re-hydrate.
Beer lovers, though, urinate much more often, so they probably lose more liquid than the beer can replenish.
In short, one or two beers can help.
On another note, don’t forget that the UV rays on this dazzlingly beautiful day are hard on the eyes. You can get some fashionable sunglasses here at BEI.
