Prioritize Heat Illness Prevention at the University of Nevada Las Vegas This Summer

Las Vegas is renowned for its extreme desert climate, but recent data indicates that the heat is intensifying at an alarming rate. According to a recent Climate Central analysis, summer temperatures in Las Vegas have warmed by 6.2 degrees since 1970, ranking the city among the fastest-warming summer locations in the USA. The National Weather Service has corroborated this trend, noting significant increases in both average daytime highs and, crucially, overnight low temperatures. When the environment does not cool down sufficiently at night, the human body faces compounded thermal stress, making heat safety a critical priority.

For the University of Nevada Las Vegas community, this escalating heat poses a direct occupational and recreational hazard. Whether you are a student walking between classes, a facility employee performing outdoor maintenance, or an event staff member managing a crowded venue, understanding and applying heat illness prevention strategies is essential for summer wellness. The university has established comprehensive protocols to mitigate these risks, but individual awareness remains the first line of defense.

Understand the Escalating Heat Risks in the USA

The warming trend in Las Vegas is not an isolated anomaly; it reflects a broader pattern of extreme heat events across the USA. However, the local geography of the Mojave Desert amplifies these effects. Paved surfaces, concrete buildings, and limited vegetation create an urban heat island effect, trapping heat and radiating it back into the environment long after the sun sets. This persistent thermal load means that individuals exposed to the outdoor environment are at risk of cumulative heat stress.

Heat illness prevention requires a proactive rather than reactive approach. Relying on how you feel in the moment is often insufficient because the physiological signs of heat stress can be subtle and deceptive. Recognizing the environmental factors—such as humidity levels, direct solar radiation, and ambient air temperature—is the foundation of maintaining summer wellness in this challenging climate.

Implement the University of Nevada Las Vegas Heat Stress Program

To address these environmental hazards systematically, the University of Nevada Las Vegas relies on its Risk Management & Safety (RMS) Heat Stress Program. This initiative provides a structured framework to help campus departments prepare for and navigate extreme summer conditions. The program is not limited to full-time faculty or staff; it explicitly encompasses contractors, volunteers, and student workers who perform duties in hot environments across the campus.

The RMS team assists departments in developing site-specific Heat Illness Prevention Plans tailored to the unique challenges of different work zones. Additionally, they conduct heat index surveys to evaluate the actual thermal load in specific areas, factoring in elements like reflective surfaces and equipment-generated heat. Departments are encouraged to register for specialized training or access on-demand modules through the CHIMERA portal to ensure their teams are adequately prepared.

Apply the Three Pillars of Summer Wellness

According to Dan Bollard, a safety training specialist with RMS, the core message of the university’s heat safety program can be distilled into three actionable words: water, rest, and shade. Mastering these three pillars dramatically reduces the risk of heat-related ailments.

Hydrate Proactively, Not Reactively

Thirst is a delayed indicator of dehydration. By the time your brain registers the sensation of thirst, your body is already experiencing a mild state of dehydration, which impairs your ability to regulate internal temperature. When engaging in physical activity outdoors, you should consume approximately 32 ounces (or four cups) of water per hour. This translates to drinking one cup every 15 to 20 minutes.

It is equally important to know what not to drink. Energy drinks, sugary sodas, and heavily caffeinated beverages are poor substitutes for water during extended heat exposure. Caffeine acts as a mild diuretic, while high sugar content can slow gastric emptying, delaying the absorption of fluids. The University of Nevada Las Vegas has installed over 100 water-bottle refill stations across 31 buildings to facilitate consistent hydration. If your work takes you far from these stations, you must carry a sufficient supply of water to last the duration of your task.

Schedule Regular Rest Periods

Heat illness can develop rapidly, particularly when individuals are focused on completing a task or moving quickly between locations. Taking short, frequent breaks allows your cardiovascular system to recover and your body to dissipate accumulated heat. Employees performing strenuous outdoor work should alternate shorter periods of activity with regular rest breaks rather than pushing through long, uninterrupted shifts.

Managers play a vital role in enforcing rest periods and must adjust expectations based on the ambient temperature and the physical demands of the work. Special consideration must be given to individuals who are new to an outdoor crew, those starting a summer assignment, or employees returning to field work after an extended absence. The university’s program heavily emphasizes acclimatization—the biological process of gradually adjusting to hot conditions. New or returning workers should incrementally increase their exposure time over a period of 7 to 14 days to build physiological tolerance safely.

Seek Adequate Shade

Stopping work provides little benefit if you remain standing in direct sunlight. True rest requires removing the body from the primary heat source. Breaks should be taken in the shade or, ideally, in a climate-controlled indoor space. If indoor access is not feasible, utilize natural shade from trees or artificial shade structures like awnings, canopies, or shade tents.

For those simply walking across campus, shade remains a critical factor. Concrete pathways and asphalt absorb and radiate significant amounts of heat, making afternoon transit between buildings particularly taxing. Planning routes that maximize shade and allowing time to cool down indoors upon reaching your destination are simple yet effective heat illness prevention tactics.

Differentiate Between Heat Exhaustion and Heat Stroke

Recognizing the early symptoms of heat illness allows for prompt intervention, which can prevent a manageable situation from becoming a life-threatening emergency. Understanding the distinction between heat exhaustion and heat stroke is a cornerstone of heat safety.

Identifying and Treating Heat Exhaustion

Heat exhaustion is the body’s response to an excessive loss of water and salt, usually through sweating. Symptoms develop gradually and may include:

• Severe headache
• Nausea or vomiting
• Dizziness or lightheadedness
• Generalized weakness or fatigue
• Irritability or confusion
• Heavy sweating
• Elevated body temperature
• Fast, weak heart rate
• Decreased urine output

If you suspect heat exhaustion, immediately move the affected person to a cooler area and do not leave them alone. Remove or loosen unnecessary clothing to facilitate heat loss. Apply cool water or cold compresses to the skin to begin lowering their core temperature. If the person is fully alert and able to swallow safely, offer frequent sips of cool water. Because heat exhaustion can rapidly progress to heat stroke, the individual should receive a medical evaluation. Call 911 if their condition worsens, if medical care is not readily available, or if you are unsure of the severity of their symptoms.

Responding to Heat Stroke Emergencies

Heat stroke is a severe, life-threatening medical emergency characterized by a failure of the body’s temperature regulation system. Warning signs include:

• Profound confusion or altered mental status
• Unusual or aggressive behavior
• Slurred speech
• Loss of consciousness or unresponsiveness
• Seizures
• Very high body temperature (above 103°F)
• Hot, flushed skin that may be either heavily sweating or completely dry

If you observe these symptoms on campus, call 911 immediately from a campus phone, or dial 702-895-3669 from a mobile phone. While waiting for emergency medical services, immediate aggressive cooling is required. Move the person to a shaded or cool area and remove all outer clothing. Wet the skin or clothing with cool water and circulate air around the person using fans or cardboard. Apply cold, wet cloths or ice packs to the high-blood-flow areas of the body: the head, neck, armpits, and groin. Stay with the person continuously until help arrives. Crucially, do not attempt to give any fluids, including water, by mouth to someone who is confused, unconscious, having a seizure, or unable to swallow safely, as this poses a severe choking hazard.

Maintaining a safe environment during the extreme Las Vegas summer requires leveraging available institutional resources. The University of Nevada Las Vegas RMS department offers both online and in-person heat stress training designed to help employees recognize symptoms, respond appropriately under pressure, and implement preventive measures. Course registrations and scheduling are easily accessible through the CHIMERA Safety Training platform.

Beyond formal training, departments are encouraged to collaborate with RMS to conduct comprehensive heat index surveys of their specific work areas. These surveys can identify hidden risks, such as radiant heat from nearby equipment or inadequate airflow, leading to practical recommendations like adjusted work schedules, job rotation protocols, buddy systems, and the deployment of specialized cooling equipment.

For real-time decision-making, safety experts recommend utilizing the OSHA-NIOSH Heat Safety Tool app. This free application uses location-based weather data to calculate the current heat index and provide hourly forecasts. More importantly, it outputs specific, actionable precautionary recommendations for outdoor work based on the exact environmental conditions. Supervisors and employees can use this tool to plan daily activities, adjust break schedules, and determine when it is unsafe to work outdoors entirely.

Maintain Vigilance Throughout the Season

Surviving and thriving during a Las Vegas summer requires consistent application of heat safety principles. The escalating temperatures across the USA demand a culture of vigilance, particularly in high-risk environments like the Mojave Desert. By prioritizing proactive hydration, enforcing mandatory rest periods in genuine shade, and knowing the critical differences between heat exhaustion and heat stroke, the University of Nevada Las Vegas community can significantly reduce the incidence of heat-related illnesses. Take advantage of the training and resources provided by RMS, look out for the well-being of those around you, and make summer wellness a non-negotiable part of your daily routine.
