The Longest Recorded Sleep Duration While there have been various reports of individuals sleeping for extended periods, the longest recorded time someone has slept is an astonishing 11 days and 25 minutes. This extraordinary feat was achieved by Randy Gardner in 1964 as part of a science fair project.
Other weird records
Previously, Peter Tripp held the first record at 201 hours and suffered from hallucinations for several days after. Between Peter and Randy, Honolulu DJ Tom Rounds made it to 260 hours. Randy tapped out at 264 hours, and slept for 14 hours straight after.
We often say that people need 7-9 hours of sleep, but some people require more sleep to feel rested. “Long sleepers” are people who regularly sleep more than the average person their age. As adults, their nightly length of sleep tends to be 10 to 12 hours. This sleep is very normal and of a good quality.
In medical terms, oversleeping means sleeping more than nine hours in 24 hours. It's associated with a higher risk of several conditions, including heart disease, stroke, and heart failure. That doesn't mean it causes those conditions. Instead, oversleeping may be a symptom of other underlying conditions.
Randy Gardner (born c. 1946) is an American man from San Diego, California, who currently holds the record for the longest amount of time a human has gone without sleep.
For millennia, people slept in two shifts – once in the evening, and once in the morning.
The bare minimum of sleep needed to live, not just thrive, is 4 hours per 24-hour period. Seven to 9 hours of sleep are needed for health, renewal, learning, and memory. Disruption of the sleep cycle from shift work creates problems for the quality and quantity of sleep.
Language switcher. Experts recommend that adults sleep between 7 and 9 hours a night. Adults who sleep less than 7 hours a night may have more health issues than those who sleep 7 or more hours a night.
Sleeping too much puts you at greater risk of coronary heart disease, stroke and diabetes than sleeping too little. Sleeping more than seven or eight hours a night, and feeling tired the next day, could indicate you have a health problem.
Sleep and Aging
Older adults need about the same amount of sleep as all adults—7 to 9 hours each night. But, older people tend to go to sleep earlier and get up earlier than they did when they were younger. There are many reasons why older people may not get enough sleep at night.
Koalas are thickset arboreal marsupials with a thick grey fur. Found only living in Australia, they mainly live in the eucalyptus trees and spend around 22 hours of their time sleeping (90%). They spend the other 10% of their day eating and sitting around.
The world record of longest kiss was set by a Thai couple Ekkachai and Laksana Tiranarat in 2013. Their kiss lasted for 58 hours 35 minutes. The couple - who had previously won the record in 2011, took home the grand prize of 100,000 Thai Baht (Rs. 23,465) and two diamond rings worth 100,000 Baht (Rs. 2,34,650).

The bad news is that short sleepers are rare. For most of us, getting only 5 or 6 hours of sleep isn't a good idea. Research shows that not getting enough sleep can affect your ability to communicate, solve problems, and recall information.
Now, he makes an effort to sleep at least six hours per night, he said in an interview with CNBC's David Faber on Tuesday. “I've tried [to sleep] less, but ... even though I'm awake more hours, I get less done,” Musk said. “And the brain pain level is bad if I get less than six hours [of sleep per night].”
The answer to this question is an emphatic no. Most people will still be impaired from sleep deficiency even if they sleep for more than twice this amount.
Altogether, it seems possible to survive without food and drink within a time span of 8 to 21 days. If a person is only deprived of food, the survival time may even go up to about two months, although this is influenced by many factors.
Stay up longer than 24 hours and your brain, now in panic mode, will soon take over and force sleep upon you. “You're basically going to have microsleeps,” Feinsilver says. Though you will appear to be awake—walking, talking, eyes open—your brain will quite literally put itself to sleep for ten to 20 seconds at a time.
If you've ever laid awake at night and wondered, "why can't I sleep?" there may be several reasons. Some common reasons you can't sleep include poor sleep environment, sleep disorders, stress, and daytime inactivity.
