Thai Ngoc – Story of a Man Who Hasn’t Slept Since 1962

Sleep is an essential component of a healthy lifestyle, with most people needing around 7-8 hours of sleep every night to maintain optimal health. However, there is one man in Vietnam who has defied the odds and has not slept in over 61 years. His name is Thai Ngoc, and his story is both fascinating and perplexing. In this article, we will delve into the details of Thai Ngoc’s unique condition and explore the possible reasons why he hasn’t slept in decades.

Who is Thai Ngoc?

Thai Ngoc, also known as Hai Ngoc, was born in 1942 in the Vietnamese province of Quang Nam. In 1973, after contracting a severe fever, he found himself unable to sleep. At first, he thought it was just a temporary condition, but as the days turned into weeks and then years, he realized that he had not slept at all.

The Condition

Thai Ngoc’s condition is known as “insomnia,” a sleep disorder that prevents people from falling asleep or staying asleep. However, what sets Thai Ngoc’s case apart is the fact that he has not slept in over 50 years. This is an incredibly long time to go without sleep, and it is still a mystery how he is able to function without it.

How Does He Survive?

Despite not sleeping for over half a century, Thai Ngoc appears to be in good health and continues to work on his family farm. He claims that he feels no ill effects from his condition and has never experienced any negative side effects from his lack of sleep.

Possible Explanations

Thai Ngoc’s case has baffled medical professionals around the world, and there are several theories as to how he is able to function without sleep. One possible explanation is that he may have a genetic mutation that allows him to bypass the need for sleep. Another theory is that he may be getting small amounts of sleep that he is not aware of, such as microsleep, a state where the brain briefly shuts down to rest.


Thai Ngoc’s story is a fascinating one that raises many questions about the nature of sleep and its role in human health. While his case is undoubtedly unique, it is also a reminder that there is still much we do not know about the human body and its ability to adapt to extreme conditions.
