Workplace Health and Wellness Topics
Workplace health articles on heat stress, back injury prevention, bloodborne pathogens, mold, respiratory health, dehydration, and occupational illness prevention.
Workplace health is the practice of protecting workers from illness, physical strain, and environmental conditions that harm the body over a shift or a career, rather than from a sudden traumatic injury. These hazards, from heat and poor air quality to repetitive strain and infectious disease, can be just as disabling as any accident, but they often build up quietly over time and are easy to overlook.
The articles on this page cover the main workplace health hazards and how to manage them. They include heat stress and cold stress, dehydration, back injuries and safe lifting, ergonomics and stretching, respiratory hazards like mold and poor indoor air quality, infectious illness such as the flu and COVID-19, chemical health risks, radiation, and mental health concerns like stress, anxiety, and fatigue.
Use these articles to prepare for a safety meeting, brief a crew before hot or cold weather, or help workers recognize the early symptoms of a health hazard before it becomes serious. They are written for safety managers, supervisors, and anyone responsible for keeping a workforce healthy, whether the work happens outdoors, in a plant, or in an office.

Frequently Asked Questions
How do you prevent heat stress at work?
Prevent heat stress by giving workers water, rest, and shade, and by letting them acclimatize to the heat over 1 to 2 weeks. Watch for early symptoms like heavy sweating, muscle cramps, and dizziness, and treat confusion or fainting as heat stroke, a medical emergency. OSHA enforces heat protection under the General Duty Clause.
Does OSHA have a standard for every workplace health hazard?
No. Some health hazards have specific OSHA standards, such as asbestos, radiation, and many chemicals, while others, including heat, ergonomics, and job stress, have no single standard and are covered by the General Duty Clause (OSHA 5(a)(1)), which requires employers to keep the workplace free from recognized hazards that can cause serious harm.
What is the best way to prevent back injuries at work?
The most reliable protection is to reduce manual lifting through better job design, using carts, hoists, and team lifts, and storing loads at waist height. When workers do lift, they should keep the load close, bend at the knees rather than the waist, and avoid twisting. Good fitness and stretching help, but engineering the lift out of the task works better than relying on technique alone.
How can employers reduce the spread of illness in the workplace?
Encourage sick workers to stay home, promote hand hygiene and cough etiquette, clean and disinfect shared surfaces, and improve ventilation. During flu season or an outbreak, added steps like distancing and masks can help. Clear sick-leave expectations matter too, since workers who feel they cannot afford to miss a day tend to come in sick and infect others.
Why does indoor air quality matter for worker health?
Poor indoor air quality can cause headaches, fatigue, and irritation of the eyes, nose, and throat, and it can worsen asthma and allergies. Common causes include mold, poor ventilation, dust, and chemical fumes. Fixing moisture problems, maintaining HVAC systems, and controlling contaminants at the source are the most effective ways to keep indoor air healthy.
Is workplace stress a safety issue?
Yes. Ongoing stress, anxiety, and fatigue affect concentration, decision-making, and reaction time, which raises the risk of mistakes and injuries on the job, and they contribute to long-term health problems. Employers can help by managing workload, encouraging breaks and time off, and making it safe for workers to speak up about stress and mental health.
