An article that I found that relates to time management is stress management. This article discusses that all people need stress. The stress we need is called eustress, but too much stress for too long is called distress. Eustress will keep managers alert, will motivate them and drive them to solve problems efficiently. Distress is a very important stress for managers to avoid with time management.
Distress happens when a manager's bodies over-react to events.
The article also explains about reactions to problems. These reactions may be over-reactions to strong reactions. Over-reactions might result in nausea, depression, and severe headaches. Strong reactions can result in insomnia, and heart disease. Managers need to handle all reactions to problems in a professional manner.
