Text B

One of the research institutes carried out an interesting experiment. Six young persons – four men and two girls did not sleep for 124 hours. They were under the constant observation of the doctors who took their cardiograms, determined the pulse and blood pressure, and carried out many other investigations.

Not to fall asleep they were allowed to do physical exercises, dance and play, but they were not allowed to take any stimulants. Vision, hearing and various reflexes were often examined during the experiment.

The experiment was successful. Its findings showed that prolonged sleeplessness increased the amount of sugar in the blood, decreased the level of vitamin B1 and B2, produced considerable increase of white blood cells and decreased the amount of iron in the blood.
