Recent studies emphasize the significance of skin microclimate in the prevention of pressure injuries (PI). The objective was to evaluate the effect of pressure loading on skin temperature and moisture in the heels of healthy adults. This is a before-and-after study performed at Brazil, in October 2022. Skin temperature (°C) was measured by an infrared digital thermometer, and skin moisture (%) using electrical bioimpedance. Ten individuals/twenty heels were evaluated. The average temperature of the right and left heel was the same at baseline (27.2 °C). It was recognized that after 30 min of pressure loading on the heels, there was a decrease in temperature, and after 15 min of pressure offloading, the temperature decreased again. It was found that at t0, the moisture of the right heel (12.6%) was lower than the left heel (15.6%). The median moisture in the right heel increased from t0 to t1 and decreased in t2, while in the left heel, there was a small variation of the median from t0 to t1, as well as to t2. The pressure loading leads to a decrease in temperature and changes the skin moisture of the heels of healthy individuals.
近期研究强调了皮肤微气候在预防压疮（PI）中的重要性。目的是评估压力负荷对健康成年人足跟皮肤温度和湿度的影响。这是一项于2022年10月在巴西进行的前后对照研究。使用红外数字温度计测量皮肤温度（℃），并使用生物电阻抗测量皮肤湿度（%）。对10名个体/20只足跟进行了评估。左右足跟的平均温度在基线时相同（27.2℃）。研究发现，在足跟施加30分钟压力负荷后，温度下降，在卸压15分钟后，温度再次下降。结果发现，在t0时，右足跟的湿度（12.6%）低于左足跟（15.6%）。右足跟的湿度中位数从t0到t1增加，在t2时下降，而左足跟的湿度中位数从t0到t1以及到t2仅有微小变化。压力负荷会导致温度下降，并改变健康个体足跟的皮肤湿度。
