“What if always feeling cold comes down to low brown fat, not bad circulation?”
You have two kinds of body fat: regular fat stores calories, 'brown fat' burns them for heat.
“brown adipose tissue and cold sensitivity”
- Target:
- brown adipose tissue and cold sensitivity
- Approach:
- BAT thermogenesis as individual temperature regulation
At-a-glance
Five dimensions of this thought experiment — the larger the shape, the more this idea is backed on each axis.
- 1
Cold triggers sympathetic response
When you are cold, your nervous system tells BAT to start burning.
- 2
UCP1 burns without ATP
Brown fat cells burn fuel and release heat instead of storing energy.
- 3
Low capacity = always cold
If you have less brown fat or it is less active, you just cannot make enough heat.
Adult humans have functional brown adipose tissue activatable by cold.
