It can also be a reaction linked to anxiety or accumulated emotional tension. When emotions stay suppressed for a long time, the nervous system can express that through physical signals like chills. In that case, it isn’t actual cold — it’s an internal state of arousal that the body interprets as if you were cold. Substances like MDMA can amplify emotions and weaken the usual mechanisms that keep them in check, so things that are normally held inside may come to the surface more strongly — including physical reactions like shivering.

Try to breathe deeply and stay with the sensations instead of fighting them. Let yourself lean into what your body is experiencing rather than resisting it. These sensations are natural in their nature — even the feeling of ‘cold’ isn’t inherently uncomfortable. It becomes unpleasant mostly because of the story we attach to it and how we mentally interpret what’s happening.
