The aim of the work was to evaluate changes in selected skin parameters under the influence of low temperature. The tests were conducted on a group of 20 women using whole-body cryotherapy. The average age of participants was 58.7 ± 7.54 years; the average body weight 77.84 ± 16.01 kg, the mean BMI 30.14 ± 5.81, and the average body height 160.7 ± 6.48 cm. The tested parameters included hydration, lubrication, temperature, and pH of the skin. The skin measurements were made on the first and tenth treatment days, before and after leaving the whole-body cryo-chamber. To assess the data collected before and after the experiment, the measurement taken at each time point were compared. After a series of ten treatment sessions, the greatest decrease was observed in skin hydration and skin temperature. No significant differences were noted for lubrication and skin pH. The analysis showed statistically significant differences in skin parameters between all measurement locations; the upper and lower limbs responded more significantly to cold than other parts of the body. It was also found that the facial skin was more lubricated and hydrated compared to other measuring locations. We conclude that varies skin parts respond differently to low temperature. Cryotherapy causes a significant decrease in temperature and hydration of the skin whereas differences in pH and lubrication of the skin remain insignificant.
本研究旨在评估低温对皮肤各项参数的影响。研究对象为 20 名女性，采用全身冷冻疗法进行测试。参与者的平均年龄为 58.7±7.54 岁，平均体重为 77.84±16.01kg，平均 BMI 为 30.14±5.81，平均身高为 160.7±6.48cm。测试参数包括皮肤的水分、润滑度、温度和 pH 值。在第一次和第十次治疗日，以及在进入全身冷冻舱前后，对皮肤进行了测量。为了评估实验前后收集的数据，比较了每个时间点的测量值。经过一系列十次治疗后，皮肤水分和皮肤温度的下降最为明显。润滑度和皮肤 pH 值没有显著差异。分析表明，所有测量部位的皮肤参数之间存在统计学显著差异；与身体其他部位相比，上肢和下肢对寒冷的反应更为明显。还发现，与其他测量部位相比，面部皮肤的润滑度和水分度更高。我们得出结论，不同的皮肤部位对低温的反应不同。冷冻疗法会导致皮肤温度和水分显著下降，而皮肤 pH 值和润滑度的差异则不显著。
