Empirical Health Evidence

Climate Stress Across South Asia

Meteorological records and clinical registries show extreme heat directly compromising physiological recovery.

19.8 Days

Annual Heatwave Exposure / Person

The Lancet Countdown reports that Indians were exposed to an average of 19.8 heatwave days in 2024, with major labor-hour and income-capacity losses.

35.2°C

Delhi Warmest Night Low

Extreme nighttime heat can remove the body's nocturnal recovery window and increase autonomic cardiac strain.

~70%

Districts with Warmer Nights

Many Indian districts now experience more very warm nights per summer, reducing sleep and recovery buffers.

Thermoregulatory Mechanics

Wet-Bulb Globe Temperature vs. Normal Air Temperature

Standard dry-bulb readings measure ambient heat. WBGT better reflects whether the body can shed heat through sweat evaporation.

Standard Dry-Bulb

40°C Shade Air Temp

Measures kinetic air temperature in isolation. It does not measure the rate at which sweat evaporates from human skin.

Key Limitation Cannot differentiate dry heat where evaporative cooling works from moisture-saturated air where heat shedding collapses.

Wet-Bulb Globe Temperature

30.8°C High Risk Threshold

Synthesizes ambient temperature, natural wet-bulb temperature, humidity, evaporative capacity, wind, and radiant solar heat.

Why It Matters

When humidity rises, sweat evaporation slows. WBGT captures that biological constraint more directly than air temperature alone.

Vasodilation

Blood pressure can drop as the heart pumps harder to move heat to the skin.

Heart Rate Drift

Thermal strain can elevate heart rate and reduce recovery efficiency.

Autonomic Fatigue

Sympathetic stress can suppress HRV and delay parasympathetic recovery.

Renal Strain

Dehydration and exertional heat load can raise kidney-stress risk.

Core Architecture

The PriSEHAT 4-Pillar Preventive Framework

Converting multimodal telemetry into daily adjustments across physiological, psychological, and environmental friction points.

Personalised Resilience Score

Individual baselines across autonomic markers, recovery state, and body-composition context.

Phenotype calibrated

Dynamic Fitness Adaptation

Heat-adjusted training loads, safer timing, hydration prompts, and exposure-aware pacing.

Exertion throttling

Mental Well-Being Adaptation

Checks for cognitive fatigue, sleep disruption, and climate-amplified psychological strain.
