Thinking about death can actually be a good thing as it leads people to bring positive changes to their lives and help others

For an awareness of mortality can improve physical health and help us re-prioritize our goals and values, according to the latest analysis of recent scientific studies.

Even non-conscious thinking about death - such as walking by a cemetery - could prompt positive changes and promote helping others, say psychologists.

The report says that past research suggests that thinking about death is destructive and dangerous, fueling everything from prejudice and greed to violence.

Such studies related to terror management theory, which posits that we uphold certain cultural beliefs to manage our feelings of mortality, have rarely explored the potential benefits of death awareness.

“This tendency for TMT research to primarily deal with negative attitudes and harmful behaviors has become so deeply entrenched in our field that some have recently suggested that death awareness is simply a bleak force of social destruction,” says Kenneth Vail of the University of Missouri, lead author of the new study in the online edition of Personality and Social Psychology Review this month.
