Vietnamese scientist discovered the secret of sleep

A group of scientists working at Harvard Medical School, led by Vietnamese doctor Dang Vu Thien Thanh, has published an important study on why some people can still sleep despite the noises around.

Researchers have found that the frequency of brain waves at night determines whether a person wakes up when there is noise around. The lower the frequency, the easier it is to wake up by noise.

According to Dr. Dang Vu Thien Thanh, the important thing in this research is that it helps scientists, doctors can predict who is more sensitive to sleep during sleep, and one of the important indicators. weight to predict the frequency of the brain.

Scientists' work is done to find out how the brain works to increase sleep, even in a noisy environment, and why some people sleep better than others. when there is noise.

To do this work, scientists have studied over 12 people aged between 20 and 40, sleeping three nights in a sleep laboratory at Massachusetts General Hospital. The first night was quiet, but the second and third nights, they were placed in a noisy environment with increasing levels.

Indicators show that participants with brainwave frequency are stable for all three nights, but on noisy nights people with higher frequencies are less awake than those with lower frequencies.

According to scientists, the results suggest that it is possible for people to be less affected by noise during sleep by making the brain produce more clock pulses, instead of using earplugs.

The new study is published this month in the American journal Current Biology. Immediately, this important discovery was published by many medical journals around the world.

Dang Vu Thien Thanh was born in 1980 in Vietnam and grew up in Belgium. He graduated with a doctorate in sleep in age 28 and became one of the world's pioneering scientists in this new research field.

Dang Vu Thien Thanh currently has a postdoctoral research program at Harvard University and works at the Department of Neurology at Massachusetts General Hospital of Harvard.

Despite being 30 years old, he has won numerous awards for European and American studies in neuroscience and sleep medicine.
