Why Does Time Feel Like It Speeds Up As You Get Older?
Have you ever noticed that when you were a kid, summer holidays felt endless, but now the years seem to fly by? This isn't just in your head. Many people feel like time speeds up as they get older. Scientists and psychologists have studied this feeling and have some interesting ideas about why it happens. It’s not that clocks are going faster. It’s about how our brains notice and remember time passing.
When we're young, everything is new and exciting. Our brains work hard to absorb all the fresh information, which makes time seem to stretch out. But as we get older, we see the same things again and again. Our brains get used to patterns and don't pay as much attention. This makes time feel like it’s moving faster. Also, the way we think about time changes. For a 5-year-old, one year is 20% of their life—a huge chunk. For a 50-year-old, it’s just 2%. This shift in perspective tricks our minds into feeling that time speeds up.
So, it's a mix of how our brains handle new experiences and how we view time as part of our life. It’s a fascinating blend of psychology and how our memories work. Understanding this can help us appreciate the moments more, even as time seems to rush by.
“A single year feels shorter as we age because it’s a smaller slice of our life story.”

If time speeds up because we see less new stuff, how can we slow it down by changing what we notice?

01
ObservationalSupported
Children perceive time as passing more slowly because they experience many new events, which makes their brains process more information.
When we are young, many things are new and unfamiliar. Our brains work harder to take in and store these new experiences. This overload of new information makes our perception of time stretch out, so moments feel longer. For example, a holiday that is full of new sights and experiences feels much longer because the brain is busy encoding many memories.
02
ObservationalSupported
As people age, the proportion of life that each year represents shrinks, making time feel faster.
A 5-year-old experiences one year as a big portion of their life—20%. But for a 50-year-old, a year is just 2%. Because of this, the brain measures time relative to the total life lived. This means the same clock time feels shorter as we get older, causing the sensation that time speeds up.
03
ObservationalSupported
Repetitive daily routines reduce the brain’s attention to time, making it feel like it’s passing faster.
When life becomes routine and predictable, the brain doesn’t register as many new events. Less new information means fewer memorable moments, which can make long periods blur together. This can cause the sensation that time is flying because our brains are not making many new memories to mark the passage of time.
04
ExperimentalSupported
Emotional intensity and attention can slow down or speed up our perception of time.
Strong emotions, like fear or excitement, can make time feel slower because the brain records more details. In contrast, boredom or distraction can make time feel like it's moving faster. This means that how we feel and what we pay attention to can change our experience of time passing.

The EmpiricistScientific viewpointLive tension
Scientists explain the speeding up of time as a mix of brain function and life experience. Our brains use new experiences to measure time. When life is full of new things, time feels slow. When life is routine, time feels fast. Also, the way we think about time as part of our life changes. This is why older people often say, 'Where did the time go?'.
What this lens notices
01Children’s brains process more new information, stretching time.
02Older adults have fewer new experiences, making time feel shorter.
03Self-awareness of age changes how we perceive time duration.

When did you last feel time slow down because you enjoyed a moment?
Why it changes the question
Thinking about times when you felt fully present can help you notice how your brain stretches time. Enjoying new experiences or focusing on details can make moments feel longer.
