Results From the Cold Water Experiment

Soon after COVID-19 arrived in USA, infectious disease experts were motivating us to wash our hands. I’d hear (paraphrased) “It doesn’t make a difference if you use warm water or cold, just wash them.” ¹

Then oil prices rose, and it cost more to run the furnace for heat and hot water.

And the pièce de résistance was from a mental health webinar that said cold showers produce a rise in dopamine (among other feel-good neurotransmitters). ^{2, 3}

This trifecta of accolades for cold water motivated me to cut back on hot water use. Besides, I’ve always looked for ways to reduce my Carbon Footprint. ⁴

So I used only cold water to wash my glasses, hands and face and to brush my teeth. I still used warm water for showering and shaving, though.

One immediate benefit was that I spent less time at the sink – I didn’t have to wait for the warm water to reach the faucet.

Then, when the oil was delivered, I was amazed to see that we needed about 40% less to fill the tank.

As for my mood, I feel pretty good considering it’s the bleakest time of the year in New England.

However, one side effect was pointed out to me during a recent screening for skin cancer. I mentioned that my fingertips were “taking a beating” in the cold weather. The dermatologist diagnosed me with Raynaud’s Syndrome. She suggested that I see a cardiologist or vascular specialist who might prescribe a vasodialator. “In the mean time, keep your hands warm. You can get thin silk gloves to fit under your regular gloves.” I decided not to mention that:

• I do not wear gloves;

• I keep the house at 66 F (19 C);

• I wash my hands with cold water.

All of the above results in vasoconstriction.

I’ve had cold hands for as long as I can remember; my mother taught me to wash my hands with cold water. I believe she was trying prevent me from getting scalded if I accidentally turned on the hot water too much.

As a young adult I read about how Vitamin E is good for blood circulation; ⁵ I figured it would improve blood flow to my hands, so I started taking it when I was a young adult. It did help. As a less young adult, I switched my breakfast from cereal and milk to almond butter and blueberries on rice cakes. Almonds are naturally high in Vitamin E, so my hands continued to feel well. But I heard that almond trees require a great deal of water, and truckloads of bees were needed in order pollinate them. And then I jumped on the “supper is the new breakfast” bandwagon.

I just started taking Vitamin E again last week; already I feel some improvement in my hands. I wonder if it will keep my blood pressure down, too.

One Step Closer to the Computerized Brain?

In testing my link to IEEE Spectrum, I was intrigued by this month's feature article, Psychiatry's Shocking New Tools, by Samuel K. Moore. The article describes how "electronic implants and electromagnetic pulses are picking up where psychoactive drugs have failed."

Medical science is still in the dark ages as far as I'm concerned. True it's not unscientific to poke at something in a systematic way and observe a result. If it can be repeated enough times, a scientist can establish a new method for obtaining that result. But this is terribly inefficient and inelegant. How long will it be before we know how the brain works and can correct the root causes of mental illness?

The new tools described in the article seem to be nothing more than modern day leaches and lobotomies. I can't wait to see what eventually "picks up where electronic implants and electromagnetic pulses fail."
