Insomnia a sleep disorder characterised by difficulty in falling or staying asleep tends to develop in people who tend to put things off, says a study.
At bedtime "people who procrastinate are ruminating about the things they need to do and haven't done" and that makes it difficult for them to go to sleep, study author Ilana Hairston from Academic College of Tel Aviv in Israel was quoted as saying.
‘The link between procrastination and trouble falling asleep seemed to be explained by people worrying about things that they wanted to get done before going to bed.’
The study involved nearly 600 people. Through online questionnaires, the researchers examined their tendencies to procrastinate, along with their sleep problems and emotional states.
The researchers found that trouble sleeping in participants could be an outcome of procrastination.
Another important dimension that the researchers uncovered in the study was hat morning people -- those who wake up early in the morning and go to bed early in the evening -- reported lower levels of procrastination and fewer sleep problems, compared to those who go to sleep late at night and wake up late -- the evening people.
The finding that evening people tend to procrastinate more than morning people is consistent with previous research, the researchers said.
