According to an American study, spending six hour asleep over a course of two weeks, force a person’s mental and physical abilities to decline to a level equal to a state after spending 48 hours awake. But how does a person’s body react to being kept awake for two days straight and dangerous it is for health? An experiment was conducted in Latvia in autumn this year to find out.

The experiment’s participant was a 22-year-old Riga resident Ilva. She spent 48 hours awake, doing everyday activities. Every 12 hours she underwent Vienna system tests under monitoring by specialists. Those tests measured changes in reaction, concentration and stress tolerance levels over a long period of time.

‘Nowadays, when more and more people sacrifice valuable sleep hours on studies, work and social life, sleep deprivation becomes a big problem for people in Latvia and around the world. Even if at first it seems that six hours is enough for sleep, the hours lost to sleep add up over time and impact the quality of everyday life later on. This experiment proved the importance of sleep in our lives. It is nothing new, considering that it is common belief that an under slept driver is as dangerous as a drunk driver,’ – said president of Latvia’s Psychiatrists Association Elmars Terauds.

According to results of the experiment, reaction and concentration of the volunteer had declined 50% in comparison with the first stage of the experiment. The number of mistakes made during tests demonstrated a dangerous trend. The volunteer’s blood pressure had also increased considerably after spending two days awake.

The experiment’s participant comments: «It was the hardest for me to get through the first and second night awake. It became hard to pay attention to all the things happening around me after 24 hours of staying awake. Each consecutive hour only added to the growing feeling of fatigue. It was becoming harder and harder to perform even simple tasks like making a meal, speaking and reading. In the last couple of hours of the experiment I thought I had blinked out of reality at some point.»

Here is a video of the experiment:
