    With the hot summer months approaching we thought this article about heat stroke might come in handy.

    Heat Stroke: Symptoms and Treatment

     Article Source:

    Heat stroke is the most serious form of heat injury and is a medical emergency. If you suspect that someone has heat stroke — also known as sunstroke — you should call 911 immediately and render first aid until paramedics arrive.

    Heat stroke can kill or cause damage to the brain and other internal organs. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes.

    Heat stroke often occurs as a progression from milder heat-related illnesses such as heat cramps, heat syncope (fainting), and heat exhaustion. But it can strike even if you have no previous signs of heat injury.

    Heat stroke results from prolonged exposure to high temperatures — usually in combination with dehydration — which leads to failure of the body’s temperature control system. The medical definition of heat stroke is a core body temperature greater than 105 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures. Other common symptoms include nausea, seizures, confusion, disorientation, and sometimes loss of consciousness or coma.

    Symptoms of Heat Stroke

    The hallmark symptom of heat stroke is a core body temperature above 105 degrees Fahrenheit. But fainting may be the first sign.

    Other symptoms may include:

    • Throbbing headache
    • Dizziness and light-headedness
    • Lack of sweating despite the heat
    • Red, hot, and dry skin
    • Muscle weakness or cramps
    • Nausea and vomiting
    • Rapid heartbeat, which may be either strong or weak
    • Rapid, shallow breathing
    • Behavioral changes such as confusion, disorientation, or staggering
    • Seizures
    • Unconsciousness


    First Aid for Heat Stroke

    If you suspect that someone has a heat stroke, immediately call 911 or transport the person to a hospital. Any delay seeking medical help can be fatal.

    While waiting for the paramedics to arrive, initiate first aid. Move the person to an air-conditioned environment — or at least a cool, shady area — and remove any unnecessary clothing.

    If possible, take the person’s core body temperature and initiate first aid to cool it to 101 to 102 degrees Fahrenheit. If no thermometers are available, don’t hesitate to initiate first aid.

    You may also try these cooling strategies:

    • Fan air over the patient while wetting his or her skin with water from a sponge or garden hose.
    • Apply ice packs to the patient’s armpits, groin, neck, and back. Because these areas are rich with blood vessels close to the skin, cooling them may reduce body temperature.
    • Immerse the patient in a shower or tub of cool water, or an ice bath.

    If emergency response is delayed, call the hospital emergency room for additional instructions.

    After you’ve recovered from heat stroke, you’ll probably be more sensitive to high temperatures during the following week. So it’s best to avoid hot weather and heavy exercise until your doctor tells you that it’s safe to resume your normal activities.

      If you are concerned about power when there is no sunshine for the solar panel, use a car battery (or several hooked in series) with an inverter to run the fan. Use the solar panel with its controller to charge the battery(ies) and the inverter to run the fan or any 110 volt device up the maximum wattage capability of your inverter. Good for charging cell phones, running tv, radios, audio sources, etc. as for the fan and no converter just use a 12 volt fan. You can also use this system to plug your cordless tool chargers into to charge those batteries. Solar panel charging systems, batteries, and inverters can be obtained at Harbor Freight, rv supply stores, electronic supply stores, hardware stores (like ACE & Home Depot, etc.).

    2. The freezer does turn on and off automatically to maintain its set point temp. It will run more and dump more heat if you make extra ice. However, if you place your ac far from the freezer , It would make a local cool spot, even though it would heat the house on agragate.

    3. Actually, this is not an evaporative cooler or swamp cooler because the cooling effect does not depend upon the evaporation of water. It is the air blowing over/around the frozen gallon jug that is cooled and then exits the PVC outlets. If anything, the frozen jug will cause moisture to condense out of the incoming air and drip down the sides of the liner to the bottom. So that means that the air exiting is going to be at a lower relative humidity than the air being blown into the bucket. A short primer on relative humidity – if the incoming air is 80 degrees F and 90% relative humidity and the outgoing air is at 70 degrees F, the humidity of that 70 degree air is going to be less because air at 70 degrees cannot hold as much moisture as air at 80 degrees. That is what the “relative” in relative humidity means. Then, as that air warms back up, the relative humidity of that air is going to drop. That, by itself, will make that air evaporate your sweat faster and make you feel cooler.

      Someone could make a deal out of this by using a special “jug” that is divided into parallel flat compartments through which the air could flow, then when freezing the jug, use salt water instead of tap. The colder ice plus the finned jug design might make this a real chiller!

    4. I understand the bucket instructions but how do you do the electrical on the fan? Could you make a list of supplies including what kind of solar panel and how you hook it up to the fan?

    5. Styrofoam isn’t the strongest thing in the world…. the bucket is added protection in more ways than one.

      • The Good Survivalist

        Yes, you can do that. Type air conditioner into the search box on to see some other options.

    6. That’s a pretty neat idea… I’m actually thinking about using it in my daughter’s room to cool it just before bedtime when it’s hot and because our home AC doesn’t cool her room enough.

      But what about that styrofoam bucket liner…!?! I live in Canada and an online search really didn’t give anyplace to go buy one. Any idea where to look for?? Thanks!

      • The Good Survivalist

        Google styrofoam bucket liner, or type in air conditioner in the search box of for some other options.

    7. I absolutely cannot believe some of the comments on here. Some of you people are vapid, disrespectful idiots, and I cannot believe the sheer number of you. If you don’t like the contraption, move on! There is no reason to tear it apart. Do not use dry ice, you risk suffocation. It is NOT a swamp cooler. Swamp coolers work by adding humidity to lower the relative temperature of surrounding air, with a blower to distribute said air. Works well in low humidity, but no swamp cooler works in areas where the humidity is routinely above 80 %, this however does NOT add humidity to the air. The bucket adds stability and extra layer of insulation to said device. Yes you can just use a Styrofoam cooler, but this will last longer. The fan is solar powered! please read/listen to all information before asking questions over and over again! It is not necessary to identify this as a “redneck contraption” really? geez. No where in here does it talk about ICE CUBES or using your ice maker to produce the ice used. It is a frozen gallon of ice. A solid block! which will take much longer to melt inside a Styrofoam lined bucket than ice cubes. No you will not be freezing any gallon of ice on the day the power goes out, so some forethought is required. No where was it suggested as a permanent solution to cooling your home, so the freezer-producing- heat argument is dead. OMG people get a freaking grip! It is a good idea, period. Thanks for sharing.

      After I googled “Styrofoam bucket liner” I learned that for $64 I can get 12 Styrofoam bucket liners. So far I haven’t
      learned where I can buy just one. Has anyone else been able to buy just one?

    9. Where do you guys come up with this nonsense? You’re not freezing a truck load of ice every day for this little AC. And I don’t need to read anyone’s mangled physics explanation because I know from personal experience. Using this little contraption in place of our AC last Summer saved us $$200 a month,

    10. I have to laugh at some of the “experts” in thermodynamics here. Apparently my house should be a furnace due to my freezer making ice and freezing corn, yet clearly it isn’t….and neither is anyone elses.

      And btw, some of you are complicating the heck out of this by getting bogged down in the details.You’re not building a jet airplane. It’s a bucket with holes cut in it for goodness sake. And here’s another thing…you don’t have to use solar power unless you only plan to use this when there’s no electricity. You can use a regular old fan you plug into the wall. Although I’m sure some expert on electricity will come along any minute to tell us that a little fan like this uses just as much electricity as an air conditioner, lol.

      BTW, where are you going to get ice when there’s no power anyway?

      For those who do want a solar panel, check ebay. Seems I remember some in the $10-$15 range.

      As I said in another post, I used a couple of these last Summer, and I’m glad I did. Did they cool my home as well as a regular air conditioning unit? No, they didn’t. They didn’t cost $200 a month to run like my air conditioner would have either. And they did make the rooms they were used in much more comfortable.

    11. You can get the styrofoam bucket liners at Home Depot (HD) or other hardware stores. I found one at HD and bought two just in case I needed them one day. Now I have a use for them!!! thanks for posting this great AC idea!!!

    12. I just made one of these this weekend. Its a brilliant idea! I altered a few things to better insulate but I am disappointed about the amount of air it blows out. Should I try a better fan? I bought one almost identical to the one in your video and even bought 2 different types and found that one does work better. Any suggestions?

    13. Sherwin Williams…about $4 (or, if your local SW doesn’t routinely stock them, you can order them online through their website…3 for around $12).

    14. I can’t get my air flow below 60 degrees. 5 gallon bucket with liner and frozen I gallon jug. Suggestions anyone? Video shows as low as 41 degrees.

      • The Good Survivalist

        Try adding a few more jugs or smaller frozen bottles of water.
        You should be able to get your air flow temp much lower.
