About this session
Greenhouse work can create a distinctive thermal environment because heat is influenced by more than outdoor weather.
Solar gain, enclosed structures, humidity, limited airflow, irrigation, crop density, heating systems, protective clothing, and sustained physical work can combine to make the environment feel significantly hotter than surrounding outdoor conditions.
The same greenhouse can also change across the day. Temperature, humidity, radiant heat, airflow, crop type, irrigation timing, work intensity, clothing, PPE, shift timing, duration, and access to cooler recovery areas all influence how much heat workers experience.
A task that feels manageable early in the morning may become substantially more demanding later in the day as solar load rises and humidity remains high.
This session helps participants understand what they can influence while keeping environmental and operational controls visible.
Workers can hydrate, use available cooling and recovery areas, plan clothing within workplace requirements, recognize early changes in function, and report recurring heat problems, but they cannot personally redesign ventilation, install shading, alter crop-house airflow, change staffing, or control the timing and duration of high-heat tasks.
What your people take away
- Understand how greenhouse temperature, humidity, solar gain, airflow, workload, clothing, and duration combine to create thermal strain
- Map heat exposure across crop rows, propagation areas, irrigation zones, potting or picking tasks, loading areas, and enclosed growing houses
- Recognize why high humidity can make the same temperature feel more demanding by reducing effective heat loss
- Use hydration, available cooling, task sequencing, clothing, movement, and recovery opportunities more deliberately
- Recognize early functional changes such as unusual fatigue, headache, dizziness, nausea, reduced concentration, or coordination changes
- Distinguish worker-level heat strategies from ventilation, shading, cooling, staffing, scheduling, work-rest, and greenhouse-design controls

What’s covered
Understand How Greenhouse Heat Load Builds
Every length- Humidity changes how the body loses heatHigh humidity can reduce the effectiveness of sweat evaporation even when the worker is drinking enough fluid.
- The greenhouse structure can amplify solar heatGlazing and enclosed growing structures can trap heat and create strong solar gain across particular houses or times of day.
- Physical crop work generates internal heatPicking, pruning, potting, lifting, carrying, and repeated bending increase heat production inside the body while the surrounding environment may already be hot and humid.
- The same greenhouse can contain different thermal zonesCrop density, shading, irrigation, ventilation openings, equipment, and airflow can create meaningful differences between adjacent rows or houses.
Build Hydration, Cooling & Recovery Into Greenhouse Work
90 minutes and longer- Hydration supports the body but does not remove humidityRegular fluid intake is important, but it cannot compensate for stagnant air, radiant heat, excessive workload, or prolonged exposure.
- Air movement can make a meaningful differenceWhere greenhouse design and crop requirements allow, improved air movement can help reduce stagnant conditions and support heat loss.
- Recovery needs to feel thermally differentA break inside another hot, humid section of the greenhouse may provide little meaningful cooling.
- Water access has to fit the workHydration plans are difficult to sustain when workers are far from refill points, cannot leave rows easily, or production demands restrict access.
Manage Seasonal Peaks, Workload & Cumulative Heat Exposure
3 hours and longer- Afternoon conditions can be very different from morning conditionsSolar gain and accumulated greenhouse heat can make the same task substantially more demanding later in the day.
- Irrigation can change the humidity profileWatering, misting, wet surfaces, and crop moisture can increase humidity during periods when workers are also physically active.
- Task rotation only helps when the heat exposure changesMoving from picking to potting may provide little thermal recovery if both tasks occur in the same hot, humid environment with similar physical workload.
- Peak seasons can build heat load across many shiftsHarvest demand, overtime, staffing pressure, and consecutive warm days can reduce recovery while thermal exposure continues.
Recognize Patterns & Strengthen Greenhouse Work Design
Full day only- Recurring heat difficulty can reveal recurring greenhouse conditionsIf fatigue, headache, dizziness, or unusually high effort repeatedly appears in particular houses, rows, tasks, or times of day, the pattern may be meaningful.
- Report the complete greenhouse conditionsUseful information may include house or zone, task, time of day, humidity, airflow, sun exposure, irrigation activity, clothing, workload, duration, water access, and recovery opportunity.
- Personal heat strategies have clear limitsWorkers can hydrate and use available recovery, but they cannot personally install ventilation, change greenhouse structures, add shade, alter staffing, or redesign production schedules.
- Aggregated heat patterns can guide better greenhouse designDe-identified workforce themes may reveal particular houses, crop zones, times of day, tasks, or environmental states associated with recurring heat difficulty.
