London: People remembering their past with negative memories are more likely to fall ill, suggests a study.

According to the University of Granada's study, people's attitude to the past, present and future influenced the perception they had of their health as well as their quality of life, a daily reported.

Those who looked back in anger found it harder to make an effort in their daily tasks and were also more likely to perceive pain.

Co-author Cristian Oyanadel, said: "We have observed that when people are negative about past events in their life, they also have a pessimist or fatalistic attitude towards current events.

"This generates greater problems in their relationships and these people present worse quality of life indicators."

The researchers assessed 50 people -- 25 women and 25 men aged between 20 and 70 -- from a randomised sample, using questionnaires and time orientation tests.

The findings were published in the journal Universitas Psychologica.
