Working hard when tired not good for the health

            Doing mental or physical work while exhausted may harm your health, according to a study from University of Alabama at Birmingham and published in International Journal of Psychophysiology.

Commenting on the study, Padma Shri and Dr B C Roy National Awardee Dr KK Aggarwal, President Heart Care Foundation of India said that fatigued people have bigger spikes in blood pressure than well-rested people while doing a memorization test.

When fatigued people regard a task as worthwhile and achievable, they increase their effort to compensate for their diminished capability. As a result, the blood pressure of a tired person increases and remains elevated until the task is completed or the person gives up.

In this study, Wright and colleagues told 80 volunteers they could win a modest prize by memorizing two or six nonsense trigrams (meaningless, three-letter sequences) within two minutes. Compared to volunteers with low levels of fatigue, those with moderate fatigue had stronger blood pressure while doing the two-trigram memorization task.
