If the average night's sleep is eight hours (ie one third of a day), one sleeps for one third of one's life. If you live, say, 75 years, that's 25 years asleep, or 9,125 days.
The average person spends about 26 years sleeping in their life which equates to 9,490 days or 227,760 hours. That's one third of our entire lives spent asleep in bed! Surprisingly, we also spend 7 years trying to get to sleep — a total of 33 years or 12,045 days!
1. Sleeping. A good night's sleep is vital for every human being to survive. Given that an average a person sleeps for 8 hours in a day, that means that an average person will sleep for 229,961 hours in their lifetime or basically one third of their life.

The average human spends roughly 79 years or 28,835 days on Earth. So, there is an average of 692,040 hours in a lifetime. Each bead in this jar represents one year. Let's take a look at how we spend the time of our lives.
Although average human life expectancy is rising, the maximum lifespan is not increasing. Leading demographers claim that human lifespan is fixed at a natural limit around 122 years. However, there is no fixed limit in animals.
For example, a baby born in the US in 2021 has an estimated life expectancy of about 76 years, according to the latest report from the National Center for Health Statistics. Our life expectancy varies depending on our current age, sex, race and ethnicity, and where in the US we live.
Let's face it: no one wakes up each morning thinking it's a great day to wait in line. And yet research suggests we spend a whopping six months of our lives doing just that.
Even without these conditions, simply sleeping less than 5 hours a night on average reduces your life expectancy by 15%. For someone with a standard life expectancy of 78 years, that is almost 12 years off your life.
Most teens today are living with mild to severe sleep deprivation. Teens actually need more sleep than little kids. Experts say teens need over nine hours a night to be healthy. But over a third of teens get only five to six hours a night.
“Women are also multi-taskers, and they do a lot at once. Because they use more of their actual brain, they may need a little bit more sleep than men. It is still debatable, but some experts say that women need twenty more minutes on average than men usually need.”
Most of us need about eight hours of sleep, and some need even more. Only getting six hours of sleep can lead to low energy, impaired mental performance, poor mood, and health issues like weight gain, high blood pressure, and type 2 diabetes.
And while the occasional long sleep is generally nothing to worry about, oversleeping several days a week could be a sign that something more serious is going on.
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.
The average person will spend 90,000 hours at work over a lifetime.
We grow up and we don't look quite the same. But all this is only on the outside. Beneath the surface, your body is aging too, and sleep loss can speed up the process. A study done by UCLA researchers discovered that just a single night of insufficient sleep can make an older adults' cells age quicker.
Across three datasets with the condition of total sleep deprivation (>24 h of prolonged wakefulness), we consistently observed that total sleep deprivation increased brain age by 1–2 years regarding the group mean difference with the baseline.
Among men and women who reported having all five quality sleep measures (a score of five), life expectancy was 4.7 years greater for men and 2.4 years greater for women compared with those who had none or only one of the five favorable elements of low-risk sleep.
We spend more than 4.5 hours each day socialising and doing activities we enjoy. A bubble chart shows a breakdown of how the average person spends their day across the globe. We spend more than 4.5 hours socialising and undertaking activities like reading a book and watching TV.
Whether they're changing jobs, upsizing their homes or just looking to try on a new neighborhood or dream city, Americans move an average of 11.7 times in their lifetime.
This is not surprising – most of us try to split our days into “work, rest and fun”, and so there are some predictable patterns. We spend the most time working and sleeping; and paid work, housework, leisure, eating and sleeping take together 80-90% of the 1440 minutes that we all have available every day.
As of 2021, the average age of death in men is 73 years old, with the most common causes of death being heart disease, cancer, unintentional deaths, COVID-19 infection, and stroke.
In 2021, the average life expectancy at birth was 79.1 for women and 73.2 for men, according to the Centers for Disease Control and Prevention. However, if a man is healthy enough to reach age 70 this year, the Social Security actuarial tables indicate he could live an average of 15.4 years more.
At the end of the study, about 16 percent of the men and about 34 percent of the women survived to the age of 90. In fact, the authors found that women who were taller than 5 feet 9 inches were 31 percent more likely to reach 90, compared to those who were under 5 feet 3 inches.
