Science explains why time perception accelerates during aging

Scientific research explores the phenomenon of why time appears to accelerate as humans age. While physical time remains constant, subjective perception is influenced by psychological, biological, and neurological factors.

One prominent theory, the proportional model by philosopher Paul Janet, suggests that time is perceived relative to the total lifespan already lived. For a child, a year is a significant portion of their existence, whereas for an older adult, it represents a much smaller fraction. Additionally, the lack of new experiences in adulthood leads to more routine-based living. Because the brain processes fewer novel memories compared to the information-rich period of childhood, long periods of time can feel as though they have passed quickly.

Neurologically, physical changes in the nervous system also play a role. Research by Professor Adrian Bejan indicates that as nerve structures become more complex and undergo degradation, the speed of electrical signal processing can change.

In a related discussion on longevity, virologist Professor Radostina Alexandrova noted that the global population of people aged 60 and over surpassed children under five in 2020, with the over-65 demographic expected to double by 2050. She highlighted that aging is not linear and involves various stages, noting that while aging is linked to chronic diseases, a positive attitude toward the process can increase life expectancy by approximately 7.5 years.
