Researching how to keep reasonable body temperatures the longest in cold environments

Cold room, same temperature
Body temperature measurers

Normal human posture
-Shoulder normal
-Shoulders back
-Shoulder slightly ''rounded'' forward. + slightly erected is possible.
Neanderthal posture, if different enough

A single person should do the same test multiple times with the same intake of food and water.

Extra: Trying different postures etc. Different methods. Slightly contracting muscles constantly and or making oneself broader.  Breathing methods. And more.
