Hi friend, 
 
Bryan Jonhson doesn=E2=80=99t cold plunge. But he is technically in a s= tate of mild hypothermia most of the time.
 
Since starting Blueprint, Bryan=E2=80=99s body temperature has dropped ~= 4=C2=B0F to 95.1=C2=B0F, with morning temperature as low as 93.4=C2=B0F.&nbs= p;
 
In context, it takes swimming a mile in icy water to achieve an equival= ent temperature reduction. 
 
Following Blueprint has h= im metabolically cold plunging 24/7.

Why Bryan doesn=E2=80=99t cold plunge
 
Bryan has tried cold plunging, but it=E2=80=99s not part of his normal r= outine. 
 
If you cold plunge and enjoy it, then you do you. There are many paths t= o optimal health. 
 
There is some early and inconclusive evidence that cold plunging has po= tential health benefits. But there currently isn=E2=80=99t enough evidence i= n cold plunging as a longevity therapy for Bryan to add it to his routine.
 
But=E2=80=A6 other protocols are cooling his body. Most people sit arou= nd 98.7=C2=B0F. Bryan runs significantly cooler, between 93-95=C2=B0F.

Why Bryan=E2=80=99s body is ge= tting cooler
 
Bryan maintains a 10% caloric deficit a= nd exercises rigorously for 1 hour almost every day. When people hear this, t= hey assume a deficit means losing weight.
 
Instead his body is metabolically adju= sting to this lower caloric intake while activity levels remain high, loweri= ng the metabolic burden.
 
Research in both animals and humans su= ggests that a lower body temperature and a lower metabolic load (the amount o= f work your body needs to do to survive) may contribute to increased longevi= ty.
Protocols that may be responsi= ble for the lower body temperature
 
What Bryan does:
