Hot Weather Health Emergencies (heat exhaustion versus heat stroke)

July 1, 2015

What is Extreme Heat? Temperatures that hover 10 degrees or more above the average high temperature for that area and last for several weeks are considered “extreme heat” or a heat wave. Humid and muggy conditions can make these high temperatures even more unbearable. Really dry and hot conditions can cause dust storms and low visibility. Droughts occur when a long period passes without enough rainfall. A heat wave combined with a drought is a very dangerous situation!

Doing too much on a hot day, spending too much time in the sun or staying too long in an overheated place can cause heat-related illnesses. Know the symptoms of heat illnesses and be ready to give first aid treatment.

There are two major types of heat illness – HEAT EXHAUSTION and HEAT STROKE. If heat exhaustion is left untreated it can lead to heat stroke. Both conditions are serious, however, heat stroke is a major medical emergency and getting victim’s body temperature cooled down is more critical than getting fluids in their body. Heat stroke can lead to death.

Things to watch for…

  • Heat Cramps
    • Muscle pains and spasms (usually first sign that body’s having trouble with the heat)
  • Heat Exhaustion
    • Cool, clammy, or pale skin;
    • Light-headed or dizzy and weak;
    • Racing heart;
    • Sick to the stomach (nausea);
    • Very thirsty or heavy sweating (sometimes)
  • Heat Stroke (also called Sunstroke) –
    • Very hot and dry skin;
    • Light-headed or dizzy;
    • Confusion, drowsiness or fainting;
    • Rapid breathing and rapid heartbeat;
    • Convulsions, passes out or slips into a coma

What to do…

  • Get victim to a cool or shady place and rest.
  • Lightly stretch or massage muscles to relieve cramps.
  • Loosen clothing around waist and neck to improve circulation and remove sweaty clothes.
  • Cool down victim’s body – put wet cloths on victim’s face, neck and skin and keep adding cool water to cloth… or if outdoors, use hose or stream. Also, fan the victim or get inside air-conditioned place.
  • Have victim sip cool water (NO alcohol – it dehydrates!)

If victim refuses water, pukes or starts to pass out:

  • Call for an ambulance or call 9-1-1.
  • Put victim on their side to keep airway open.
  • Keep cooling down their body by placing ice or cold cloths on wrists, neck, armpits, and groin area (where leg meets the hip) or keep adding water to cloths. Also fan the victim.
  • Check victim’s ABCsAirway, Breathing, & Circulation.
  • Stay with victim until medical help arrives.

Remember, HEAT STROKE (a.k.a sunstroke) is a medical emergency and can cause the victim to slip into a coma — getting a victim’s body temperature cooled down is more important than getting fluids in their body!

Turning body heat into clean energy

March 25, 2013

Tegwear body heat into energyDid you know … someday the heat that YOU produce might power your personal electronics..?!

Spectrum reports Perpetua Power’s TEGwear Technology is developing a chip that converts body heat into electric energy .

“We absorb the heat from your body, and that heat is funneled through a thermoelectric generator that converts it into electric power,” says Perpetua Power Vice President Jerry Wiant. The result: a single, square-inch TEGwear chip generates enough power (up to 3 volts) to run anything from the accelerometer in your pedometer to the wireless headset for your smartphone.

The physics behind TEGwear is basic: Your body is always generating heat, even when you are asleep. And heat, regardless of the source, excites electrons. The flow of electrons, in turn, generates electricity. The tricky part is harnessing enough electricity to power a small device. Wiant says TEGwear will do just that, as long as the chip is either touching your skin or separated from it by only a thin layer of clothing.

TEGwear-powered devices are still in development and won’t hit the market until 2014. But this clean technology has many potential applications, from mobile health to national security.

The company demo’d the device on a new Swatch Touch watch at the annual Consumer Electronics Show in Las Vegas a few months ago. In addition, they have a grant from the National Science Foundation to develop a prototype wristband to track Alzheimer’s patients as well as funding from Department of Homeland Security’s Science and Technology Division to power wearable devices used for surveillance operations.

turning body heat into clean energyThey have also partnered with several private companies to develop body-powered smartphone accessories (like headsets), health-monitoring devices (such as wearable heart-rate monitors), and military applications (like monitoring a soldier’s vital signs and location while on a combat mission).

Sounds kinda Matrix-ish … with very cool potentials for the preparedness industry.
