The key to unlocking a robust long life lies in our evolutionary past. Our DNA has evolved for over 2.5 million years and our bodies adapted in extreme conditions. The ways of our ancestors–the ways that Liver King has lived for the last 20 years–are better known as the 9 Ancestral Tenets.

Comfort is not good for the organism. This is why the sixth Ancestral Tenet is "Get Cold".


What are the benefits of getting cold?


Improves blood circulation so the arteries work more efficiently at pumping blood, therefore boosting our overall heart health *

Promotes “hardening,” which results in increased tolerance to stress and disease *

Upgrades the immune system by increasing glutathione (our master antioxidant) and decreasing inflammatory markers *

Intentional cold exposures initiate adaptive processes and response mechanisms that are hardwired into our genes.

Cold exposure benefits include:

  • Boosting heart health through improved circulation and increased tolerance to stress
  • Upgraded immunity, and enhanced metabolic flexibility
  • Rhonda Patrick, PHD writes “cold exposures increase cold shock proteins including one in the brain that repairs damaged synapses and in muscle prevents atrophy, how a cold-induced catecholamine lowers inflammation and pain by decreasing the levels of 3 inflammatory mediators.”

How Do I start?


Start with cold / hot shower contrasts for 30 seconds at a time. At first, you’ll down right hate it because it is uncomfortable.

Continue the shower contrasts over a 30 day period. Take notice how you feel afterwards.

It gets easier because the adaptive mechanisms, including the smooth muscles that line the blood vessels, adapt, they get stronger, faster and more efficient at doing what they were designed to do.

You will notice that your ability to withstand cold will increase considerably after only a few days.

Like any other stressor, we adapt, it gets easier, and it starts to feel amazing.
