Understanding Time Perception and Aging Effects

Can it really be true that we have gone through the first quarter of 2026 already? I am always surprised at how fast time passes. Yes, classically this is a common concern. But why does time seem to be going faster and faster each year? What makes it seem this way? Is this a real issue that medical journals have tackled? I went to work researching this subject and here are my findings:

Time seems to accelerate with age primarily because the brain processes fewer novel experiences and memories, making monotonous, routine days blend together. As we age, our brains encode fewer distinct memories, and because we rely on the density of new memories to measure the passage of time, years feel shorter.

Key factors influencing this phenomenon include:

• Lack of Novelty: Childhood is filled with “firsts”—new places, skills, and experiences—which leads to detailed, slow-seeming memories. Adult life is more routine, leading the brain to pay less attention and store fewer unique memories, resulting in a “compressed” perception of time.
• Proportional Theory: A year feels faster because it constitutes a smaller fraction of your life. For a 10-year-old, one year is  of their life; for a 50-year-old, it is only .
• Brain Neural Changes: The aging brain processes information more slowly, taking in less data per second, making external time appear to move faster.
• Memory Encoding: When we experience familiar routines, our brains encode them less richly, causing the days to feel like they “skip” or blend.

How to Slow Time’s Perception:
To make time feel slower, experts suggest introducing novelty, such as learning new skills, traveling, varying your daily routine, and practicing mindfulness to engage with the present moment
