Procrastination doesn’t just hurt your productivity and performance. It also negatively affects your health. In a new study published in the journal JAMA Network Open, Swedish researchers recruited over 3,500 college students to determine the relationship between procrastination and poor mental and physical health. They compared students with a greater tendency to procrastinate with students with a lower tendency. Nine months later, the researchers found that higher levels of procrastination were associated with higher symptoms of depression, anxiety and stress. Students with higher levels of procrastination were also more likely to report disabling pain in the shoulders or arms, worse sleep quality, more loneliness, and more financial difficulties.
