National Health observances (NHOs) are special days, weeks, and months dedicated to raising awareness about important health topics. By highlighting these health observances, organizations can offer their employees an easy and simple way to learn more about their health and well-being. Additionally, companies can reinforce and strengthen the impact of their wellness initiatives by aligning the elements of their wellness programs with the topics and themes being observed each month.
