Heat Stroke Prevention for Tea Picking
Project Overview
Tea picking often takes place in hilly or mountainous regions with strong sun exposure and poor ventilation. During high-temperature seasons, especially in spring and summer, tea workers are prone to heatstroke due to prolonged bending, insufficient hydration, and the absence of cooling equipment.
High-Risk Groups
- Female workers: constant bending leads to excessive sweating and dehydration
- Older workers: reduced heat tolerance and delayed reactions
- Seasonal laborers: unfamiliar with local terrain and weather, lack preventive awareness
Key Work Scenarios and Risk Analysis
Direct-Sunlight Hillside Tea Gardens
Low vegetation and strong sunlight create heat accumulation.
- At-risk: Full-day workers without sun protection
- Tips: Avoid work after 10 AM, set up shading tents
High-Humidity Mountain Tea Fields
Heavy dew and dense air limit sweat evaporation, increasing heatstroke risk.
- At-risk: Elderly wearing thick clothing
- Tips: Use breathable clothing, hydrate more frequently
Closed Ecological Tea Gardens
Artificial barriers trap heat inside, limiting airflow.
- At-risk: Workers operating inside enclosures for 1+ hour
- Tips: Rotate shifts every 30–40 minutes, monitor body temperature
Management Policies for Heatstroke Prevention
Without Wearables
- Distribute sun hats and quick-dry uniforms
- Enforce hydration breaks every 2 hours
- Install visual flags or audio announcements for heat alerts
With CMN Heat Alert Wearables
- Real-time skin and ambient temperature detection
- Auto alerts via vibration + beeping + red light
- Wearable on wrist or sleeves with NFC and waterproof options
- Heat map reports for scheduling and supply optimization
Why CMN Devices Are Ideal for Tea Picking Fields
Dual-Temperature Recognition
Calculates core body temperature trends using both skin and ambient data.
90-Second Consecutive Sampling
Ensures accuracy with 4 out of 6 readings triggering the alert.
Adaptable Form Factor
Customizable to fit workwear, supports humid and sweaty environments.
Data Integration for Operational Planning
Generates daily workload reports to help manage shift and water supply layout.
Conclusion and Recommendations
Tea picking is a high-exposure, high-labor job often overlooked in heat safety protocols. CMN heat warning wearables can reduce emergency incidents while enhancing efficiency and worker safety. We recommend all tea gardens incorporate smart heat alert systems into their management plans.
