Staying Safe in the Heat: Why Water, Rest, and Shade Should Be Non-Negotiable 

Post by:Kim Horwedel

As National Safety Month comes to a close, we turn our focus to a critical but often underestimated risk in the workplace—heat-related illness. As temperatures rise, so do the risks for many workers across industries, especially those in manufacturing, logistics, construction, landscaping, and warehouse environments.  

Heat illness doesn’t just occur under the blazing sun. It can happen indoors in poorly ventilated spaces, during physically demanding tasks, or even on overcast days when conditions are humid. When the body is unable to cool itself effectively, it can lead to serious health issues such as heat exhaustion, heat cramps, or in the most severe cases, heat stroke—which can be life-threatening if not treated immediately. 

Common contributors to heat-related illness include high temperatures, direct sunlight, heavy clothing or PPE, dehydration, and a lack of rest or cooling opportunities. New or returning workers are especially vulnerable if they haven’t yet acclimated to working in warmer conditions. 

According to OSHA, heat-related illness is preventable when three fundamental elements are in place: water, rest, and shade. This approach forms the core of a safe, heat-aware work environment. 

Workers should drink water frequently—about one cup every 20 minutes—even before they feel thirsty. Relying on thirst alone isn’t enough to maintain proper hydration, especially during physically demanding work. Employers should ensure easy access to clean, cool water throughout the day, while also discouraging energy drinks or sugary beverages that may contribute to dehydration. 

Scheduled breaks are equally important. Resting in a shaded or air-conditioned space allows the body to cool down and recover. The frequency and duration of breaks should increase with the intensity of the work and the temperature of the environment. If a job requires strenuous physical effort, particularly in high heat, breaks aren’t just recommended—they’re essential. 

Providing adequate shade or cooled rest areas is a basic but powerful way to reduce heat stress. Indoors, employers should ensure proper airflow and ventilation. Outdoors, shaded tents or covered areas can make all the difference. These spaces should be close to the worksite to minimize disruption while maximizing safety. 

A successful heat safety strategy also includes training and communication. Employees need to know how to recognize early signs of heat stress in themselves and their coworkers—symptoms like dizziness, headaches, nausea, confusion, and fatigue should never be ignored. Encouraging a buddy system and fostering open communication can help ensure concerns are addressed before they become emergencies. 

While employers are responsible for creating heat-safe environments, workers also play a key role in protecting themselves and each other. Employees can take proactive steps to reduce their risk of heat illness by: 

  • Drinking water consistently throughout the day—not just during breaks 
  • Avoiding caffeine and sugary drinks that contribute to dehydration 
  • Taking rest breaks when needed and seeking shade or cool areas 
  • Wearing lightweight, breathable clothing and sun protection when applicable 
  • Being alert to early warning signs of heat stress in themselves and coworkers 
  • Speaking up immediately if feeling unwell or overheated 

Preparedness and personal responsibility go hand in hand. By staying hydrated, knowing when to rest, and using shade effectively, workers can stay focused and healthy—even in extreme conditions. 

Employers have a responsibility to create a heat safety plan tailored to their workforce. This includes adjusting work schedules around the hottest parts of the day, gradually increasing workloads for new or returning employees, and emphasizing the importance of hydration and recovery time. These preventive steps are not just about compliance—they’re about valuing people and prioritizing well-being. 

At The Reserves Network, safety is built into everything we do. We partner with employers who take every measure to protect their teams, and we provide resources to ensure our associates are prepared for the environments in which they work. As National Safety Month concludes, we reaffirm our year-round commitment to safe, supportive, and productive workplaces.
