"...a simple agent such as water, which is cheap and easily available, is often neglected for a complicated system of therapy which is not so effective."
- J.S. Coulter
After using them, young children have lovingly dubbed these socks, “Magic Socks”, as have some adults I know! The traditional name of this home therapy, however, is “Warming Socks”. Now, before you envision your piggly wigglies being snuggled into nice toasty socks which were pre-warmed in your electric clothes dryer, oven or microwave, please allow me to wipe that image from your mind's eye. This is a therapy involving socks that are warm; however, the name can be a bit confusing because the socks are actually applied cold. The warming part of the therapy (hence the name) relies on utilizing a warming process supplied by your very own body.
Warming socks are useful in cases of colds, flu, sore throat, ear infection, headache, migraine, nasal congestion, coughs, sinus infection or in any inflammation/infection of the throat. The socks work best when they are used for three nights in a row - and at the first sign(s) of illness.
Here is the How-To:
* The warming socks duet (wet cotton covered by dry wool) will not result in your bed becoming wet.
Why the "warming socks" are useful:
This is how they work -
The cold causes an initial vasoconstriction (narrowing of blood vessels which slows blood flow). The body senses the cold and its effect so internal signals are triggered which initiate vasodilation (relaxation and widening of blood vessels) to increase blood flow to the feet to warm them. The heat begins to build up from the influx of blood and because the feet are insulated within the socks, but because the cotton socks are still wet, evaporative cooling begins to take place, bringing back the initial cold phase.
Thus the cold/vasoconstriction and warm/vasodilation phases continue to cycle back and forth until the cotton socks are completely dry. This is a beneficial cycle; it is a constant, gentle, self-modulating treatment with tonic effects on the body. This vacillation between the cool and warm temperatures is what leads to increased circulation (blood flow) to the feet and to a decrease of blood in the congested areas (the upper respiratory passages, head, and throat). It is a reflexive action by the body - an involuntary response to a stimulus. This increase in circulation, as well as the decrease in congestion, also allows the body to better deliver fighting members of its immune system army to the sites where they are most needed.

Yes, you can make yogurt without a thermometer. How do I know? Because I've been doing it for over 40 years. And I'll tell you here, in a little while, how I've been doing it. It's true that yogurt "recipes" call for heating the milk to 180 degrees F, cooling it down to 110 degrees F, adding the starter culture and then maintaining a steady temperature while it incubates. And it's true that if the milk is too hot when you add the starter culture then you will be killing all those lovely bacteria that you had hoped would start reproducing. But have you ever wondered what the yogurt-making folks of times past did prior to the invention of cooking thermometers or even electricity? If you get to pondering the history of yogurt you may end up not feeling intimidated at all about NOT following a yogurt "recipe" to the T.
On their website, The Dairy Farmers of Canada state the following:
Yogurt is the most popular fermented milk in the world (1).The word yogurt or yoghurt or yoghourt is Turkish in origin. It is a tart, custard-like food made from milk that has first been heated and then inoculated with a bacterial culture; the bacterial action then curdles the milk (2).
There are benefits to fermenting milk. During the fermentation process the milk protein casein is broken down, which allows many people with milk intolerance to freely enjoy milk in the form of yogurt. Additionally, the active bacterial cultures, while turning the milk into yogurt, are producing lactase, the enzyme which allows us to digest the lactose (milk sugar) in milk (3,4). And did you know that during the fermentation process both the vitamin B and the vitamin C content of milk increase (3)? How cool is that? Yogurt is simply good food. The beneficial bacteria in yogurt, as well as the by-products they produce, such as lactic acid (from the breakdown of the milk sugar lactose), aid our bodies in the fullest possible digestion of the foods we eat plus protect us from infection-causing bacteria, including those that cause "traveler's diarrhea" (3). So you can see that our gastrointestinal (GI) system really benefits when we eat yogurt, which is great since our GI system contains nearly 70% of our entire immune system (5)!
So, on to the business of making yogurt. I won't be explaining the why, just the how. The KISS principle.
Types of milk easily obtainable in southern Indiana:
Here are the general directions of how I make my yogurt (yes, without a thermometer):
You can ferment your yogurt anywhere from 4-24 hours. It will usually coagulate within 3-4 hours, resembling the texture of custard. The shorter the fermentation time, the milder the yogurt and the fewer beneficial bacteria it contains. You might be interested to know that commercial yogurt is fermented for relatively short periods of time.
Why do I ferment my yogurt for 24 hours? Well, it gives the bacteria time to consume 100% of the lactose while they are reproducing. And reproduce they do - into incredibly high numbers. Yogurt made this way contains 3 billion cfu/ml so that in just 1 cup (236 ml) you'll get over 708 Billion beneficial bacteria; this is about 50 times as much as the typical 15 Billion in one capsule of a commercial probiotic (6). As you can see, 24 hour yogurt is a low-cost source of probiotic. Plus it is easy to digest, lactose-free, nutritious AND it tastes sooooo good!
Want a great yogurt maker?
If you'd like to make the 24 hour yogurt then you might like a yogurt maker like mine. I have been using a Yogourmet Electric Yogurt Maker for several years now (I purchased mine while I was in Canada for school). I love it and highly recommend it, especially if you are making the 24 hour SCD yogurt. Though the Yogourmet came with a thermometer, old habits die hard and the thermometer had been sitting unused in the drawer until I felt the need to verify temperatures for this article.
MAKING YOGURT WITHOUT AN ELECTRIC YOGURT MAKER OR A THERMOMETER
Since you may want or need to make yogurt without an electric yogurt maker, I'll explain what I have done over the past 40 years and sometimes still do. I've only owned my Yogourmet for the most recent 5 years or so out of the past 40 so when I say these are tried and true methods, I mean it ;>). Read on -
2 more ways to keep your yogurt cozy during the fermentation process:
1) In a gas oven with only the pilot light on; this is pretty straight forward. Just place your prepared milk with the starter culture into containers (wide-mouth quart canning jars work well as containers; don't fill them too full) and then into the oven with only the pilot light on. Just don't forget you are making yogurt and accidentally preheat the oven for a pot roast - oh my!
2) In a Styrofoam cooler (I use the thick-walled ones); I bring water to a boil and fill 1 or more quart canning jars (depending on the time of year), screw on the lids and place the jars inside the cooler along with the glass canning jar(s) of future yogurt. Again, don't fill your milk jars too full; you are fermenting, remember. Then I tuck wool sweaters or old towels around the jars in the cooler and replace the lid. If fermenting for a few hours or overnight, this should be sufficient, but if you are making 24 hour yogurt then you will have to renew the hot water in the jar(s) in the morning. I have my own system pretty much down pat since I heat with an indoor woodstove and the room temperature fluctuates quite a bit throughout the day and night. You will need to experiment with how many jars of hot water work best for your particular situation; with practice you'll get the hang of this method.
There is more of an art to using a Styrofoam cooler (or even a well-insulated cardboard box) versus a gas oven's pilot light. Too much heat will speed up the fermentation process and you may open your cooler to find a jar of separated curds and whey (don't ask me how I know this). No worries - it's still edible. Open the jars very carefully since it is likely that fermentation gases and some pressure has built up if the yogurt is "overdone" (again, personal experience). Pour off the whey and either drink it (rich in minerals), use it in cooking or use it as starter to make your own lactic-fermented vegetables. Sprinkle a little Celtic Sea Salt on the curds and enjoy. With too little heat your yogurt won't "make"; i.e. it will look like the regular runny milk you started with instead of custard. Give it to the cat or your neighborhood possum and try again with a new batch of milk OR turn it into acid curdled cheese. Here is one method; a short 2 minute long tutorial - "Make cheese using old milk" (video).
Enjoy your yogurt!
