Scientific notes: 2026-11-11 · Research connections: 12 November 2026

Key findings

52/53 studies concerned heat. Reported associations commonly involved sleep, activity and heart rate; individual exposure often differed from nearby weather-station measurements.

Study design & setting

Study design and methods

Population, setting or evidence base

Mostly high/upper-middle-income countries; urban settings and climate chambers. PRISMA-ScR review of wearables during weather extremes. 53 studies, 55,284 participants;search through September 2021.

Methods

Six-database search plus Google Scholar/reference screening; independent review and narrative synthesis of exposure, health and device-validation studies.

Limits to interpretation

Limitations

Heterogeneous heat definitions; prototype/invasive/obtrusive devices excluded; little evidence in vulnerable populations and low-income settings. No pooled effect or universal validation estimate.

Research relevance

Explains why individual and indoor exposure measurement can complement area-level climate data.
