Episode notes
Norepinephrine Boosts Brain and Body
- Cold exposure triggers a robust release of norepinephrine, improving mood, focus, and attention.
- This neurotransmitter also aids vasoconstriction to conserve body heat during cold stress.
Cold Shock Proteins Protect Brain
- Cold exposure induces cold shock proteins like RBM3 that protect and regenerate brain synapses.
- This mechanism could have implications for treating neurodegenerative diseases.
Cold Lowers Inflammation and Pain
- Cold exposure reduces inflammation by increasing norepinephrine, which inhibits inflammatory cytokines like TNF alpha.
- This anti-inflammatory effect may relieve pain and improve mood disorders linked to inflammation.
