Primal Primer 14 (Fitness)
Homo sapiens have a unique adaptation among mammals crucial in survival and success: the ability to sweat. This external climate controlled attribute plays role in thermoregulation, allowing humans to maintain stable core body temperature in extreme internal and external conditions of work and heat.
Reduced Body Hair – Evolution resulting in less body hair enhances the efficiency of sweating. With less fur to trap heat, sweat evaporates more quickly, enhancing the cooling process.
Efficient Thermoregulation – Body heat dissipates through evaporative cooling. When the body heats up, sweat glands release moisture on the skin; evaporating to cool the body and prevent overheating.
Persistence Hunting – Intense sweating, combined with bipedalism gives humans the advantage in hunting. Early humans can run or walk long distances during the hottest parts of the day, chasing down prey until prey is overheated and cannot continue.
Adaptation To Diverse Land – Sweating enables Homo sapiens to survive in a variety of environments of hot savannas, deserts, and temperate regions; especially important as our species migrated out from Africa.
Detoxification – Sweat leeches small amounts of trace minerals from the body (lead, cadmium, arsenic, mercury) and toxins (bisphenol A or B; BPA).
Skin Health – Sweating cleanses the skin pores by pushing out dirt, oil, and impurities.
Truth In Sweat
Sweat was a constant state for our ancestors. Although living today requires less manual action, we should strive for activation of sweat systems due to numerous benefits and genetic pathways augmented from this state of adaptation.
If you’ve ever questioned your workout intensity, observe the saturation of your attire. If sufficiently intense, there should be no dry cloth. A murder scene in the wake of your session; splatters and streaks of sweat communicating effort. Saturation is the situation; from this proxy, there is no misallocation of time, purpose, or question of result.
~Cave Implementation~
Engineer workouts to elicit sweat. Crank the space heater in summer. Throw on a hoodie or sauna suit. Workout under the sun when most people seek shade. If your workout is tuned right, you achieve levels of saturation without aid; but if the intention is to Maximize Misery, bolting on adverse conditions will supercharge workout intentions (calorie burning, mental strengthening, and enacting heat shock proteins).
Let Sweat Be One Measure Of Man.
