Study links modern life to psychological fatigue

A study published in April 2026 in Behavioral Sciences by researchers based in Singapore suggests that the pace of modern life may be causing psychological fatigue due to an evolutionary mismatch between human biology and current societal structures.

Humans evolved for different environments

The researchers argue that humans, shaped by a hunter-gatherer lifestyle, are now living in environments that are vastly different, leading to issues such as chronic anxiety, loneliness, exhaustion, allergies, depression, and burnout.

Modern life as a "race against the clock"

The study highlights how modern life often resembles a "race against the clock," punctuated by incessant notifications and constant connectivity. People are increasingly managing tasks such as sorting emails on public transport, listening to podcasts while doing household chores, and checking step counts before going to sleep.

Constant stimulation increases anxiety

According to the researchers, our alert system, which was designed to respond to specific dangers and then return to a calm state, is now constantly stimulated by an overload of information and threats. This constant stimulation may contribute to an unprecedented level of chronic anxiety.

Technology increases efficiency and stress

The study provides an example of how modern technology, such as real-time tracking apps for public transport, increases efficiency but also heightens stress related to time management and erodes patience. The cultural pressure to monetize every waking hour leaves little room for recovery and blurs the boundary between work and leisure.

Boredom and nature reduce stress

The researchers also reference a 2014 experiment by psychologist Timothy Wilson, in which participants preferred to administer electric shocks to themselves rather than experience boredom. This suggests a deep-rooted need for stimulation, even though boredom may have served an evolutionary purpose by prompting humans to seek meaningful activities.

Balanced lifestyle may help

The study notes that modern life has reduced opportunities for movement and contact with nature, which are essential for well-being. It also points out that while technology has improved living conditions and access to information, the accumulation of changes may weaken psychological resilience. The researchers suggest that regaining a more balanced lifestyle may require reintroducing elements such as calm, non-optimized times, boredom, and regular contact with nature.
