Test order decided by a Latin square design
Follow-up
5 min after 4 min of cold exposures

May inform sex-stratified interpretation of cold pressor responses in research; leaves open mechanisms and clinical relevance beyond healthy youth.
Do cardiovascular and norepinephrine responses to cold pressor tests differ between young healthy men and women?
Young healthy men exhibit a greater blood pressure response to local cold exposure than women, which is not mediated by parallel differences in heart rate or venous plasma norepinephrine.
McLean et al. (1992) studied this question.
