CAN WE SMELL WHILE SLEEPING?
Two researches were made about this. In 1997, 10 persons were made to sleep in the research hall and fire-smokes were made in the hall. 2 out of 10 woke up. It was therefore found out that it is not possible that one cannot wake up from sleep only by smelling fire smoke, during fire accident, while sleeping.
The second test was made during 2004. 6 young persons, aged 20 were selected and were trained to breathe only by nose. Peppermint having good fragrance and pyridine, which has a foul smell been kept and the odors were passed through the nose of the sleeping persons and researches were made. They also made researches in the 4 stages of sleep.
In the first stage of the sleep, some people woke up. In the next stages, nobody woke up. The odor of ‘pyridine, though cause to wake up sometimes, it did not wake up those who are in deep sleep. Whatever may be the sleeping stage, sound wakes them up.
