A core temperature increase of 1.5–2°F suggests an intense psychedelic experience, likely due to a large psilocybin dose (28 mg psilocybin, 32 mg combined psychoactive content).

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

First-ever thermal profile of an intense psilocybin dose.
We produced the first ever face and upper body thermal map of a magic mushroom journey. A core temperature increase of 1.5–2°F suggests an intense psychedelic experience, likely due to a large psilocybin dose (28 mg psilocybin, 32 mg combined psychoactive content). Heat was redistributed to the core, consistent with 5HT2A–mediated autonomic activation, which can include increased sympathetic tone, lasting through the peak and early post-peak of the experience.
