概括
追踪手腕皮肤温度 (WST) 的消费者可穿戴设备显示,在某些周期阶段与激素水平有负相关性. 对于月经周期跟踪的算法需要考虑WST的变化.
科学领域:
- 生理学 生理学 生理学
- 内分泌学 在内分泌学.
- 可穿戴技术可穿戴技术
背景情况:
- 消费者设备越来越多地用于外围体温 (PBT) 监测,特别是用于月经周期跟踪.
- 周围体温和月经周期期间荷尔蒙波动之间的关系尚未完全理解.
- 手腕皮肤温度 (WST) 是可穿戴设备中通常测量的PBT指标.
研究的目的:
- 调查月经周期期间每晚手腕皮肤温度 (WST) 和关键激素水平 (雌激素代谢物E3G,黄素激素LH) 之间的关系.
- 评估人口因素和自我报告的压力对这种关系的潜在影响.
- 为在月经周期和荷尔蒙跟踪中使用的可穿戴设备开发算法提供信息.
主要方法:
- 50名参与者收集了生理数据,包括每晚的WST,每天的步数和葡萄糖水平.
- 测量了激素水平 (E3G,LH),以及自我报告的日记条目和压力水平.
- 进行了统计分析,以将WST与激素水平相关联,控制混变量.
主要成果:
- 当这些激素低于平均值时,观察到WST和激素水平 (E3G,LH) 之间存在显著的负相关性.
- 尽管人口统计和自我报告的压力有所变化,这种相关性仍然很强.
- 在周期中期的荷尔蒙峰值和WST波动之间注意到了更大的变化,这可能是由于WST和基本体温 (BBT) 之间的差异.
结论:
- 手腕皮肤温度 (WST) 与月经周期期间的荷尔蒙变化存在复杂的关系.
- 观察到的差异表明,WST可能不会直接反映基本体温 (BBT) 追踪中通常使用的核心体温变化.
- 穿戴式月经周期跟踪算法应考虑WST趋势的变异增加,以提高准确性和可靠性.

Hormonal Regulation of the Menstrual Cycle
312
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

The Menstrual Cycle
725
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

Body Temperature
917
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Menses Phase
241
The uterine cycle begins with the menstrual phase, which is considered day one of the cycle and typically lasts about five days. This phase is characterized by the degeneration and shedding of the stratum functionalis, the functional layer of the endometrium.
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...

Secretory Phase
600
The secretory phase of the menstrual cycle, spanning from day 14 to 28 in a typical 28-day cycle, is a period of significant physiological changes in the female reproductive system. This phase commences immediately after ovulation and is characterized by the preparation of the endometrium for potential embryo implantation.
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...
