Temperatures at which people are most comfortable vary 15-20°F (10°C)

• Employees too cold in the summer (any coats or space-heaters in the office?), or too hot in the winter is a terrible waste and shows how much people vary
  
• Uncomfortable employees are generally not as happy with their employer or as satisfied with their job, and sometimes have lower moral
  
• Desired temperature often varies with
  - Age
  - Job activity level
  - Gender
  - Other (genetics, fitness level, country/area of origin, etc.)

The Temperature at which a person functions best is the temperature at which he/she is most comfortable

• Temperature discomfort is not just in the mind - as with other discomforts, the body communicates that its current situation is bad / unhealthy. Per the Productivity sidebar, bodies of warm-blooded animals physiologically work harder when too warm or too cold
  
• This physiological stress takes energies and focus away from work
  
• To relieve temperature-induced stress, employees often take more and/or longer breaks to break-rooms, other offices, outdoors, etc. to regain comfortable body temperatures
