Why the study?
Does localized skin cooling alter sympathetic nervous system activity and pain sensation in healthy subjects?
Does localized skin cooling alter sympathetic nervous system activity and pain sensation in healthy subjects?
Intensely painful cold stimuli elicit a progressive, temperature-dependent increase in muscle sympathetic nerve activity and arterial blood pressure.
No takes yet. Share an insight, caveat, or question.
Cold immersion may heighten sympathetic drive in healthy subjects; leaves open relevance to clinical cold exposure or cardiovascular risk.
Kregel et al. (1992) studied this question.
