About BHVD

The Cold Shift is published by BHVD.

BHVD developed The Ice Sack and the Neuropause practice format. The Cold Shift is the field guide: it documents what research supports, what BHVD proposes, and what remains untested about controlled cold as a category.

Ownership and conflicts of interest

BHVD makes and sells The Ice Sack. BHVD built The Cold Shift. This creates an inherent conflict of interest: the organization producing the education also produces the product.

To manage this conflict, The Cold Shift holds every claim — including claims about its own product — to the same evidence classification system. Brand hypotheses are labeled as brand hypotheses. Unverified product specifications are marked as unresolved. Research from other delivery methods is not presented as Ice Sack evidence.

No sponsors. No advertising. No affiliate revenue. Revenue comes from product sales through theicesack.com.
