Temperature Tracking

Continuous monitoring of skin or core body temperature trends for health insights, fever detection, illness prediction, and menstrual cycle tracking. Skin temperature measured at the wrist or finger runs 3-4°C below core temperature and varies with ambient conditions, blood flow, and circadian rhythm. Wearables establish personalized baselines and detect meaningful deviations. Elevated nocturnal temperature often precedes symptom onset in respiratory infections by 1-2 days, enabling early illness detection. In menstrual tracking, basal body temperature rises approximately 0.3°C (0.5°F) after ovulation due to progesterone, remaining elevated until the next period—this thermal shift confirms ovulation occurred. Temperature also reflects circadian rhythm health, with normal nighttime drops supporting sleep quality. Athletes use temperature trends to monitor training load and recovery status. Factors affecting readings include alcohol (raises temperature), room temperature, blankets, and device positioning. Some devices measure continuous temperature; others sample periodically. Temperature tracking has expanded following COVID-19 awareness of fever as an early symptom indicator.
