老年女性在高热度和高湿度下比男性出汗率更低. 然而,两性都经历了类似的核心体温升高,这表明与热相关的健康风险相似.
科学领域:
- 环境生理学环境生理学
- 老年学是指老年学的学科.
- 热调节 热调节 热调节
背景情况:
- 在全球范围内,极端高温事件正在增加,造成与高温有关的疾病的风险.
- 热暴露的性别特异性风险,特别是在老年人中,需要进一步调查.
研究的目的:
- 为了确定老年男性和女性是否对热应激表现出性别特异的生理反应.
- 评估湿度对老年人温度调节的影响.
主要方法:
- 16名老年男性和15名老年女性暴露在39.1°C和25.1%的相对湿度 (RH) 中.
- 参与者接受了坐着休息和低强度自行车运动,并逐渐增加RH.
- 测量包括出汗率,心率,热感,胃肠道温度 (Tgi) 和皮肤温度 (Tsk).
主要成果:
- 老年女性的出汗率明显低于男性,特别是当RH超过30% (p < 0.001) 时.
- 在胃肠道温度 (p = 0.64) 或皮肤温度 (p = 0.07) 的上升方面,没有发现性别之间的显著差异.
- 男人和女人的心率和热感没有差异.
结论:
- 老年女性在特定的炎热和潮湿条件下,与男性相比,出汗率降低.
- 尽管在出汗方面存在差异,但老年男性和女性在核心和皮肤温度上表现出相似的增加.
- 这表明,无论性别,老年人暴露在热量中的生理应变和健康风险都相当.

Factors Affecting Body Temperature
Factors may include:
Requirements for Human Life
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...
