What would you do and why?
you may be surprised that your 'good intentions' may actually contribute to futher patient decline and death..keep in mind that medical staff even in a clinical setting can get diagnosis wrong. Eg: ECG - ST segment elevation that can be present in hypothermia , may actually be due to Myocardial Infarction.
Paramedics that have attended patients where they were found to be Asystolic were administered Epinephrine and Atropine without apparent success and declared dead, later showed signs of movement and found to be still clinging to life.
Hypothermic patients indicating sign of simulated rigor , may lead one to assume it's all too late and over for them.

There's a few things the layman can do if they notice someone with uncontrolled shivering. Call 911. If they're wet, get them out of wet clothes and into dry ones - which may be some of your own. Get a fire going and get them over it. If you have a mylar blanket, drape it behind them to hold in the heat from the fire. If you have hot liquid, get it in them. Vigorous rubbing and hugging using your body heat. Hopefully you can keep them conscious until help arrives.
We teach a lot of this in Hunter Safety. Being in the north, it doesn't take much. Cold rain and sub 50* temps can do it. Everyone should carry at least 3 ways to make fire and a safety blanket. I do.

I know of at least one case where a child was hypothermic, and his parents or whomever was with him got him to a car and turned the heat on full blast. It caused too quick of a body temperature change and supposedly the child died due to it.
I am unsure of any pre existing conditions, nor am I sure about how extreme the initial hypothermia was, but it is something to keep in mind.

As someone that has been thru the ice, strip down, get a fire going and as much as it hurts cover with what you have

Yes well little youngsters and the elderly do have greater metabolic challenge when dealing with hypothermia..and anyone with pre-existing heart/lung issues. No doubt it would be counter intuitive to many if one was to tell them to keep the patient cool until you can reach proper comprehensive med. care.

My general answer to your OP question was "not enough", so thanks for the info in your OP and the post by CharlieFoxtrot.
Due to years of low desert dwelling, I have a few times been able to detect incipient - and full-bore - heat stroke, and have been able to help to some extent. But not enough in at least one instance, east of Yuma in August.
Thanks for the info and reminders.

I've had two instances where someone was mildly hypothermic. First was my son after he took a header in waders when we were duck hunting in Nov. Shivering, mumbling, extremities started getting numb. He was 12. I got him to the truck, got him stripped down and gave him my dry clothes and coat. I was only in my long underwear and drove him back to camp with the heat on but not at full blast and seat warmers. Sort of a gradual warm up. Got him into a hot shower and drink some warm chicken broth. He was good about an hour after the dunking.
Second time I was a chaperone on an overnight school field trip. Sort of survival skills at a YMCA camp. The kids were soaking wet trying to navigate canoes on the lake in the early spring. Teachers were no help and quite ignorant of the hypothermia risk. Camp counselors were oblivious as well. I strongly suggested in no uncertain terms to the head honcho that the kids needed to change into dry clothes pronto. He was pissed about his schedule being thrown off, but relented. Fast forward a few hours after dinner and they're all out at the pavilion in the driving rain doing a scheduled activity. Two young girls, maybe 70 lbs each, were shivering noticeably and holding each other to keep warm. I grabbed a teacher and took them back to the lodge, got their wet coat off, and built a raging fire in the big fieldstone fireplace while the teacher made hot cocoa. That was another happy ending. Their moms thanked me a few days later. It doesn't take much.

If I remember my cold weather training for a Ski Cadre course I took in the army, one thing to be sure to do is protect the body core. If the patient is in advanced stages of hypothermia and near or already unconcious, prop their feet up and their head so the blood flow is relatively confined to the body core. Get a fire or other heat source close enough to the body to start to warm them- including your own body if necessary. After a short time monitoring heart rate, breathing, and other functions, start to massage extremities to get the blood flowing to the rest of the body. If I remember correctly, the definition of hypothermia is when the body core temperature drops below 91 degrees (?) .... once the body core starts to raise, use whatever insulation or additional heat sources you can to slowly raise the body temp. Watch for signs of heart issues- heart palpitations, fast heart rate, signs of heart attack in severe cases. This whole procedure can take some time so if medical assistance is available they should have been alerted by now. If you are like a lot of us and in a hunting camp where medical assistance isn't available or can't reach you, this can be a pretty rough procedure to go through. You can get hypothermic in 50 degree weather if the conditions are right. Getting wet is one of the conditions that can cause this, but far from the only thing to watch for. I used to train people how to avoid this, how to treat it, and how to recognize it- but that was quite some time ago and my memory of it isn't that great any more...
I had hypothermia on an elk hunt many years ago and almost died. My doctor prescribed tranquilizers for me to slow down my heart due to a hyperthyroid condition I was being treated for. This was just days before an elk hunt and about a week before I was supposed to get my thyroid treatment done at the hospital. Once we got to camp, we had a huge snowstorm and blizzard. In these conditions I was late to my stand in the morning so I hustled up a fairly large hill in about two feet of snow and 50-60 mph winds to get to the position we had chosen the day before and I was alone. My sweat inside my clothing froze solid and I started to lose body heat. I got confused and had a tough time finding my truck but finally was able to after about an hour and literally crawled the last hundred yards and into the cab. My heater wasn't working because I had just put a new engine in the truck the week before and I had connected the heater core lines backwards. Camp was about 2 miles back so I had to drive with the window open and looking out because I couldn't defrost the windshield. Once I got back to camp I went in the tent and looked in the mirror my buddy had hung on one wall for some reason. My face, lips, everything was white as snow and I couldn't figure out what to do so I just sat down. I couldn't figure out how to build a fire, I couldn't even figure out how to get water out of our big water jugs and have a drink- and I was extremely dehydrated. After about an hour or two my buddy came back to camp and immediately put water in a water basin he kept on a table he kept on a table and washed his face. I immediately rushed over, used the water to wash my face to get some stimulation into my brain and slowly started to feel almost aware. My buddy finally noticed I wasn't looking good and got a fire started. I took about four hours around the wood stove to get back to feeling almost normal. Yeah, I know, everything that could go wrong did go wrong and I was to blame for most of it. I've neve forgotten the lessons I learned that day, though.
One of the things to watch for is extreme fatigue. If you let your body get run down on an outing in cold conditions, you are much more susceptible to becoming hypothermic and as your mind succumbs you will be unable to care for yourself quite quickly. One of the many reasons hunting with a buddy is a good idea, especially in extreme conditions...

There's a few things the layman can do if they notice someone with uncontrolled shivering... Indicative of stil being in the Sympathetic NS mechanical thermogenesis stage..triggering peripheral vaso-constriction and tachycardia. .Body doing what it can to thermo-regulate and prioritize. If they stop shivering , does that mean things are looking Up?...not necessarily.. They may now have descended below the 28 C.Deg. threshold...where sympathetic catecholamine release is blunted in the chemical synapse/ neuromuscular junction...more bad news to follow as result.

Using laymans' terms would be much more helpful.

He's using terms that in all likelihood he doesn't understand. He goes in for pretending knowledge, to bignote himself. The bloke has considerable form.

I broke my leg guiding an elk hunt, down in a canyon, slipped crossing a creek and snapped my leg where my foot could touch my knee. Anyway it's a long story I've written about on here before.
Short version is I was soaked, it had been raining for a few days and no way to make a fire. The hunter had to leave me and hike out to get help. 10 hours later when I got to the hospital they didn't care about my leg, it was the hypothermia.
I'll say this about it, after the initial shivering and shaking eventually stopped I felt warm, all pain stopped, even my normal aches and pains... never felt so good. I knew what was happening and didn't care.
I can see why people take their coats and stuff off before they freeze to death. they feel good.
Dying of hypothermia is as good as any way and better than most.

Shivering, mumbling, extremities started getting numb... On the topic of immersion (prolonged) , folks more often die due to drowning as result of suppressed breathing reflex before becoming significantly hypothermic. Those that go in cold water and go down quick likely a result of cardiac impacts of dysrhythmia.

I can see why people take their coats and stuff off before they freeze to death. they feel good. In severe stage , some will paradoxically undress However even in moderate stage patients will report feeling warm...a flesh and bones trial done with USCG volunteers some decades ago , had them do a cold (1hr) immersion and then into warm bath recovery... sensory perception told them they felt warm and fine, Carotid Body-core temp readings indicated otherwise.. .in fact core temp was lower after the warm up period. Now picture this; A person looses sympathetic response function so no longer able to concentrate blood to core so it disperses to the periphery/extremeties dropping core temp, someone then puts them in hot bath which further vasodilates extremities drawing more blood away from core where it's needed most. So now we are looking at hypotension and reduced perfusion (blood flow) to organs. Cold and under-perfused organs don't work that well. Liver doesn't metabolise lactates correctly and if the heart reaches stage of differential cooling, will play games with ion exchange across pacemaker cell membrane and alter electrophysiologic characteristics of cardiac action potentials. Renal/kidneys, something called Cold Diuresis results in too much urine. Excess fluid loss leads to dehydration and the urine being rather diluted, means toxins in the blood are not being properly excreted.

16 commercial fishermen were pulled from the water off the east coast of Nova Scotia after thier ship sank. They were all alive after spending several hours in very cold water. The crew from a near by vessel —with no emergency training —pulled them from the water. They wrapped them up in blankets and soaked their hands and feet in warm water. That killed 15 of the 16 fishermen.
Warm the body core- not the extremities—blood rushing back from hands and feet will lower core body temp very quickly.

Sa a hard hat diver it was a five day a week thing. Bad enough I couldn't grap the the handle to change the temperature after the tenders would put me in the shower. I lived.
