There are a few things that influence your body's ability to regulate heat. Nutrition, clothing, behavior, and practice are the big ones. Nutrition is important as far as making sure you're properly hydrated and are replete with electrolytes. It's possible to become dehydrated even while drinking enough water. To fix this, make sure you consume salts such ...

It takes about 2 years to fully get used to heat. A ball cap is not good. Get a vented brim hat. The old straw hats are very good, they absorb moisture, and cool by evaporation. The woven reed cone Asian style hats are good. Wear light colors. Cotton wicks moisture away to help cool. Tropical wool is the best there is. I recommend a 60% cotton 40% wool mix. ...

The first solution that comes to mind is a "zeer", or pot-in-pot refrigerator. However, this functions best in hot and dry environments as it relies on evaporation to work. Such a device is constructed by nesting one clay pot inside another, with a layer of sand between them (about an inch on the bottom, a few inches on the sides). The sand is then soaked ...

Serious heat related illness in wilderness medicine is broken up into two categories, heat exhaustion and heat stroke. This blog post from NOLS has a pretty good overview of the two (including signs & symptoms [S/Sx], and treatment). The information is similar to what would be covered in a WFA/WFR course regarding heat illness. That being said, I would ...

Although technology has brought us many conveniences most of them require supporting power or other technology. You seem set on refrigeration and you say: "I am willing to go to just about any extent short of buying a fridge and a generator." Perhaps you should consider solar panels (photovoltaic) and an electric refrigerator. Both technologies are ...

You'll need to do several things: Change your habits and foods Work Combine several techniques First, you need to more carefully consider the necessity of refrigeration. Refrigerators are used to keep food in a "safe" temperature zone where bacteria is less active, and this requires temperatures close to freezing. Passive cooling, such as root cellars and ...

The amount of water you require can vary a lot depending on the conditions and your level of exertion and conditioning. Dehydration can affect your physical and mental performance quite quickly so it should be a high priority. Similarly, if you are hiking between water sources you need to make a careful judgement on how reliable those sources are. Can you ...

I go to Arizona and hike around the desert pretty much every summer. One thing I've noticed that makes a difference is to immerse yourself in the heat. Don't try to avoid it; embrace it. I have experienced up to 121 °F (49 °C), that I know of. While that certainly felt hot, the limiting factor for walking around was how much liquid I was willing ...

Keeping things against the floor with insulation on top is often the best approach for keeping them cool. This could be under the front seats or in the spare wheel compartment, but many modern cars have compartments under the boot (trunk) floor. The tops of these compartments provide some insulation from the worst of the greenhouse heating, but the kit ...

The two main tricks for storing things in a car in hot temperatures are, Try to keep the car as cool as possible, Park in the shade. Use a reflective windshield shade to reflect some of the heat that would otherwise be absorbed and heat up the inside of the car. Keep the things inside of other things and keep them out of direct sunlight. Coolers work ...

Speaking from a few occasions, I can describe this list: (Anectodal being what it is, YMMV). Generally, I was aware of feeling hot and discomforted by heat A very alarming generalsense of unease. Something is not as it should be. Light-headedness; like when you stand up quickly sometimes, but persistent Slight nausea, though likely connected to the first ...

My idea is to keep your thermos bottle full with ice chips, then when thirsty simply dump some of your ice into a small cup then add your beverage! Save as much as you can by returning the unused ice to the thermos for future use. Of course its best to stick with the same beverage, and or water, so flavors don't get mixed if you use the ice again. I still ...

Because water evaporates at any temperature over 32 DegF, a swamp cooler or evaporative cooler is possible in any climate that needs cooling (though perhaps not in a powerful enough fashion depending on the cooling required). In a still body of water, the evaporation rate is proportional (in some form) to the humidity of the air, the air temperature, the dew ...

It there is a well nearby use it. 1. by dropping sealed and floating containers to water and then using a net to get them back. This works very well with beer cans. 2. Put the food in a bucket and use rope to lower it near the water.

As there are already a lot of good answers, I thought I'd just tackle the one bit I haven't seen addressed. tldr: Drinking water and passing water can help remove excess heat in itself, disregarding the effects of sweat evaporation and benefits of avoiding dehydration. Start drinking more before you plan to go out (12-24hrs), if you start fully hydrated ...

As a native Floridian I can tell you dealing with the heat takes a lot more awareness then dealing with the cold. Cold is easy compared to heat. Mostly because cold effects can be felt, while heat can’t (in general). So in Florida it can get well over 37 C in the sun, and it’s humid. It's normally around 35 C to 38 C, Humidity is generally in the 80s - ...

I lived in a city where temperatures didn't rise above 31°C until I was 18 year old, and then moved to another where summer easily gets above 42°C (real feel can reach 54°C). I'm a climber, and I do climb in those temperatures. I can only advise you based on my experience. When I got here I was constantly passing out in the street/bus. I have Polish ...

I have tailored on and off for many years and am somewhat familiar with the differences in various fabrics. Not all I read on the internet am I inclined to believe about various fabrics, but I would say that linen is a good choice for underwear garments. However, linen does tend to wrinkle easy so I would recommend a linen blend. When traveling, I would ...

Ground temperature up to 30 feet deep varies as a function of depth and the seasonal temperature. The further down you go, the more it "averages" the location's seasonal variations and the more it lags the seasonal changes. Hole in the ground In southwest canada (vancouver, for instance) you can expect that four feet down the ground will be around 50F (...

If your ambient temperatures (air/water/earth) don't get down below refrigerator temperatures (2-4 C), and in summer I suspect they don't, then the second law of thermodynamics says you can't do this without an energy source. Since electricity is out, you could consider a propane refrigerator.

I wanted to add some details that might compliment the other answers here by looking at specific signs and symptoms that help evaluate dehydration. My experience as an EMT weighs in here, and links are below for learning more details. However, dehydration does not affect everyone in the same way. Each person will have a different tolerance level to ...

Consider splitting the kit. Put dressings, scissors, hemostat, tape ... in one for non perishables. I like using a fishing tackle box. Athletic tape, antiseptic powder, saline solution, and bar soap all hold up in the heat pretty well. In a car accident with major problems you are not worried about ointments. Airway, bleed, stabilize, and get ...

There are good answers regarding where to put it and how to best protect it. I'll add a few insights to those excellent answers. Separate the insensitive stuff from the sensitive stuff. Bandaids, compresses, burn-gel, dest. water, antiseptic, some NSAIDs - these things usually withstand heat well. So, epi-pens and other medication (you can ask at the ...

If you only use PET bottle try to put a neoprene sleeve around them. Neoprene is used to insulate the tubes of the so called "hydration systems", that is those bladders with a tube going from the bladder to your mouth when you want to suck water from it. Neoprene works pretty well both in keeping the heat in winter and the opposite as you need. It doesn't ...
