Preparing for Extreme Heat This Summer
As we head into the hottest part of summer, make sure your workers are prepared for extreme heat. Hot environments combined with physical activity and other factors, like clothing and personal protective equipment (PPE), can increase the body’s temperature and cause heat stress. Heat stress can result in heat-related illnesses like heat stroke, heat exhaustion, heat cramps, or heat rashes.
Workers at risk of heat stress include outdoor workers and workers in hot environments, such as construction workers, landscaping workers, agricultural workers, miners, firefighters, food service workers, and others. Heat can also increase the risk of other types of workplace injuries caused by sweaty palms, fogged-up safety glasses, and dizziness.
Here are some recommended strategies to prevent heat-related illnesses at your workplace:
**Monitor**: Employers should monitor the weather and plan for when a heat wave is forecasted. While employers and supervisors should monitor workers in hot conditions, they can also put a buddy system in place where workers observe each other for symptoms of heat-related illness.
**Rest Breaks**: In the heat, workers need more time to rest and cool down. Employers should provide a cooler place, a shaded or air-conditioned area is best, and encourage workers to take breaks. Adjust how often and how long rest breaks are based on conditions (e.g., temperature, humidity, sunlight, physical tasks) and PPE worn because wearing PPE can increase the risk of heat-related illnesses.
**Hydration**: One of the most important ways to prevent heat-related illness is drinking enough fluids. Workers need to drink small amounts of water throughout the day so that they never become thirsty. For moderately intense work that lasts less than 2 hours, workers should drink approximately 1 cup of water every 15 to 20 minutes.  During prolonged sweating lasting several hours, workers should drink sports drinks containing balanced electrolytes. Employers should make cool, potable water readily available and encourage workers to hydrate before, during, and after work.
**Acclimatization**: Over time, our bodies can go through a gradual process known as acclimatization, which helps us adapt to heat exposure. New workers on an 8-hour shift should spend only about an hour and a half in the heat on their first day. Their exposure time should increase slowly—no more than a 20% increase per day. Experienced workers should have no more than 50% exposure the first day. By the fourth day, most healthy workers should be able to tolerate 8 hours in the heat assuming they are well-hydrated and have appropriate rest breaks.
**Training**: NIOSH recommends implementing a heat stress training program, in a language workers and supervisors understand, which includes the following:
Identifying and controlling heat hazards and understanding environmental risk factors
Understanding individual factors that may impact workers’ risk for developing heat-related illness
Recognizing the signs and symptoms of heat-related injuries and illnesses
Administering first aid and CPR for heat-related illness
Activating emergency medical services quickly when neededNIOSH has several useful resources including the OSHA-NIOSH Heat Safety Tool App, which can be used to plan outdoor work activities based on how hot it feels throughout the day. NIOSH webpages related to heat stress, heat-related illness, and hazards to outdoor workers provide detailed information, along with a link to the NIOSH Criteria for a Recommended Standard: Occupational Exposure to Heat and Hot Environments.
Heat-related illnesses can be prevented for a healthier summer. Follow NIOSH on Facebook, Twitter, Instagram, and LinkedIn for safety tips and information all summer long.
Research RoundsElevated Blood Pressure and Heart Rate More Common After Physical Activity at Work Than Leisure
If you ever have felt energetic after an active weekend but exhausted after an active workday, your experience may be backed by science, according to research recently published in the journal *Occupational & Environmental Medicine*.
Previous studies suggested that physical activity at work is associated with decreased heart health, while physical activity for leisure may have an opposite, protective effect. To look at the biological mechanisms underlying this difference, researchers at NIOSH and The University of Pittsburgh compared heart rate and blood pressure between physically active non-workdays and workdays.
Study participants included 19 middle-aged men whose jobs in food service, material moving, healthcare, or maintenance involved light physical activity. Their average age was 47 years, and 68% were white. All participants wore activity and heart rate monitors for 7 days and a blood pressure monitor on one non-workday and one workday. The researchers then averaged heart rate and blood pressure readings between non-workdays and workdays with comparable activity levels.
The results showed that heart rate over 24 hours and upon waking was higher on workdays compared with non-workdays. On workdays, the average 24-hour heart rate was 84 beats per minute, compared with 79 on non-workdays, while the waking workday heart rate was 89, compared with 83 on non-workdays. Similarly, higher diastolic blood pressure—the bottom number on a reading that measures blood pressure between heart beats—occurred on workdays: 75, compared with 73 on non-workdays. No differences occurred in systolic blood pressure, which is when the heart contracts, or in night-time blood pressure or heart rate.
In other, preliminary findings, increases in blood pressure and heart rate remained elevated for longer periods after being physically active at work versus leisure. Overall, the study suggests that public-health recommendations for physical activity may need to be different for physical activity at work than at leisure.

New Research Framework Accounts for Social Influences on Work and Health
Most of what we know about work and health is based on research through a framework of exposure and disease, but this approach does not address social influences on work and health. To better understand this relationship, the complexity of work must be viewed in the context of society.
A new framework was recently proposed to guide research on work, health, and health inequity. The framework, published in *SSM – Population Health* by a NIOSH researcher and collaborators, offers ways to investigate social factors that determine the level of exposure to hazards at work.
With an emphasis on work, the researchers identified three types of social institutions that create differences in health-related conditions: work and employment, general social policies, and resources for working people. The researchers also identified underlying sociopolitical forces—historical, cultural, and economic beliefs and ideals—that configure these social institutions in certain ways and systematically place groups at higher risk. These forces include racism, sexism, and other stereotypes that sort groups into different kinds of jobs. The resulting divisions may influence the success of occupational safety and health regulations as well as the access to needed resources.
To demonstrate how social institutions affect work-related health, researchers compared characteristics of work and health between the United States and the European Union’s 28 member states (EU28). One notable difference was the proportion of workers reporting poor general health: <3% in the EU28 and >9% in the United States. In the population overall, the proportion reporting poor general health is about 9% in both regions, which suggests that U.S. workers with health problems continue working while their EU28 counterparts leave the workforce. Various social institutions support people differently during the time of injury, sickness, and recovery (e.g., healthcare access, income replacement, paid leave). As a result, differences in social institutions between the United States and EU28 may explain poorer health in the U.S. workforce, according to the researchers.
