Cold Showers Keeps You Fit, Saves Money and Energy

Cold Showers Result in Fewer Sick Days and Promote Sustainability

3000 volunteers in Netherlands were asked to shower as they normally do, but finish their morning showers with a 30, 60, or 90 second blast of cold water, for 30 consecutive days. This experiment was conducted by Waterless Co, makers of no-water urinal systems.  
The work attendance records of these volunteers were later analyzed. It was observed that on average, the cold showering volunteers were absent nearly 30% less than people in a control group, who took their usual, warm morning showers. There did not seem to be any difference, however, whether the volunteers took 30, 60, or 90 second showers. The results were the same.
Dr. Geert A. Buijze, who headed the research team believes that the cold water made the volunteers feel more energetic, and hence the reduction in sick days. "The cold water “triggers our fight-or-flight response, causing hormones to be released and our metabolism to go up,” he continued. In fact, two-thirds of volunteers continued to take cold showers daily even after the study was completed.
Umpteen researches have proved that cold water showers lead to long term fitness, including increasing fertility. Hot water baths have their benefits too, mostly soothing and hence temporary in nature. 

How Do Cold Showers Lead to Sustainability?

The shower water in the experiment was at about 50 degrees Fahrenheit (F). In the U.S., the average shower water temperature is 105 degrees.
In fact, hot showers require more water than cold showers, because of the extra time spent waiting for the flow to heat up. According to a research at Lawrence Berkeley National Laboratory, an average of 5.21 gallons per household, per day spirals down the drain before anyone even starts bathing. 
Then the gas required for heating the water. Overall, water heating can account for up to 25% of a home's energy use, and showers use 37% of the hot water in the average home.A shower that consumes 25 gallons or less is considered to be energy efficient. It takes 8.3 British thermal units (Btus) to raise the temperature of one gallon of water 1 degree Fahrenheit, and a hot shower is usually 105 degrees. (Input water is usually at 55 degrees.) So, a 25 gallon water- efficient steamy shower requires 10,375 Btus of energy. Considering 6 showers a week, we are looking at an energy expenditure equivalent to 1 mega watt which can power upto 1000 homes in the US.  Also, the electricity bill for a single resident with an electric water heater who took a 65-degree shower once a day will be about $50 per year, while that for a daily hot shower would be to the tune of $200 per year.  
Klaus Reichardt, CEO and founder of Waterless Co is keen to look at this research through the sustainability lens. He says, “Taking cold water showers can also promote sustainability. Studies report that if one person takes a [cold] shower at 65 degrees (F), they would pay $50 a year in energy costs. Someone else taking a [regular] hot water shower would pay more than $200.00 annually. Try finishing up a shower with cold water. You might feel better, be more energetic, save some money, and protect the environment, all at the same time.”
