在16名年轻（18-34岁）和8名中年（35-51岁）血压正常的参与者中研究了户外服装和反复寒冷暴露对血压、心率、皮肤温度和热感觉的影响。使用了四套冬季服装：不带帽子的常规冬季服装、带帽子的常规冬季服装、带额外一条裤子的常规冬季服装以及带帽子和额外一条裤子的常规冬季服装。参与者在-5A ℃下暴露四次，每次15分钟，穿着不同的服装，每次冷暴露后，在25 A ℃下复温25分钟。结果表明，收缩压和舒张压在寒冷时升高，不戴帽子时升高更明显。戴帽子不仅降低了冷暴露时的血压反应，还促进了前额皮肤温度和血压的更快恢复。这些发现令人鼓舞，值得进一步调查，以更好地了解在冬季穿着适当服装的好处，特别是老年人和心血管疾病患者。
The effect of outdoor clothing and repeated cold exposure on blood pressure, heart rate, skin temperature, and thermal sensation was studied in 16 young (18-34 years) and 8 middle-aged (35-51 years) normotensive participants. Four winter clothing ensembles were used: regular winter clothing without a hat, with a hat, with an extra pair of pants, and with a hat and an extra pair of pants. The participants were exposed four times to -5A degrees C for 15 min wearing different clothing ensembles in counterbalanced order and each cold exposure was followed by 25 min of rewarming at 25A degrees C. The results showed that systolic and diastolic blood pressure increased in cold and increased more when a hat was not used. Wearing hats not only reduced the blood pressure response during cold exposure, but also promoted faster recovery of forehead skin temperature and blood pressure. These findings are encouraging and warrant further investigations to better understand the benefits of wearing appropriate clothing in the winter, especially among older people and patients with cardiovascular diseases.
