I have to be reminded of simple truths often. Otherwise, in my comfort zone, I will forget them.
Over the past couple of days I have been reminded several times it is impossible to get better at anything if you work on it from a place of comfort. Improvement comes from training on the edge of ability. One of those reminders came in the form of a book review of What Doesn’t Kill Us: How Freezing Water, Extreme Altitude and Environmental Conditioning Will Renew Our Lost Evolutionary Strength by Scott Carney.
From the review:
One of the primary premises in Carney’s book is that our technological sophistication, which allows us to live in a very climate-controlled situation within a narrow comfort range, impacts our health in surprising ways. For most people alive today, climate-controlled comfort has been the experience throughout our life, and we have no reason to believe that exposure to harsh conditions might be beneficial.
But, according to Carney, the evidence suggests the human body actually needs those extreme temperature variations. We evolved to develop resilience and health through those changes.
With this in mind, I checked the temperature of my swimming pool – 68° F. That’s a bit chillier than I’m accustomed to. But maybe the temperature is just right.
