Who requires the most sleep?

Finland, the Netherlands, Australia, the United Kingdom and Belgium are also high in terms of sleep, with Ireland lagging far behind. In this special feature, we delve into some of the myths surrounding sleep duration. Among other questions, we asked ourselves if anyone can really survive sleeping 5 hours every night. We also found out if lack of sleep can be fatal.

However, it is worth noting that some rare people seem to work well with less than 6.5 hours of sleep each night. There is evidence that this could be due to a rare genetic mutation, so it's probably not something someone can train themselves for. The belief that sleep deprivation can kill could have its roots in a study from the 1980s. Rechtschaffen and his colleagues found that if they deprived rats of sleep with a particular experimental method, they would die after 2 to 3 weeks.

However, lack of sleep is not painless for humans. In 1965, Gardner's parents were worried about their son. They asked Lieutenant Commander John J. Navy Medical Neuropsychiatric Research Unit in San Diego to observe him.

It describes a constant deterioration in function. For example, by the second day, Gardner found it harder to focus his eyes. By day 4, he struggled to concentrate and became irritable and uncooperative. On the 4th, he also reported his first hallucination and delirium of grandeur.

On day 6, Gardner's speech slowed down, and by day 7, he was dragging as his memory worsened. Paranoia began on day 10, and on day 11, her facial expression and tone of voice became inexpressive. Both his attention and memory capacity decreased significantly. In addition, if we constantly deprive our body of sleep for months or years, the risk of developing various conditions increases, such as cardiovascular disease, hypertension, obesity, type 2 diabetes and some forms of cancer.

People's sleep needs vary, but most adults need 7-9 hours a night to feel refreshed and function the next day. Older adults spend more time in bed, but unless a sleep problem has developed, the requirement to sleep is similar to that of their younger adult life.
