Gen Z’s Longevity Obsession Could Be Accelerating Burnout and Biological Ageing
Cold plunges, sleep trackers, supplements and “biohacking” routines have become part of everyday life for many younger adults trying to improve their long-term health.
But despite Gen Z and Millennials being among the most wellness-focused generations yet, growing evidence suggests their nervous systems may actually be under more strain than previous generations.
Our latest findings reveal a concerning contradiction at the centre of modern wellness culture. While younger people are investing heavily in longevity and optimisation, many are simultaneously experiencing chronic stress, poor sleep and reduced recovery, all of which can place the body into a prolonged state of physiological overload.
This blog explores what the latest data reveals about stress and recovery in younger generations, why experts believe nervous system dysregulation may contribute to accelerated biological ageing, and how supporting the body’s recovery systems may become increasingly important for long-term health.
Why wellness culture may be backfiring
Interest in longevity and health optimisation has surged over the past year, with younger adults increasingly turning to wearable technology, sleep tracking and recovery-focused routines in an attempt to improve long-term health.
However, experts warn that many people are pursuing these habits while simultaneously operating under chronic stress and poor recovery.
The stress crisis affecting Gen Z and Millennials
Although wellness routines are becoming more common, stress and burnout levels among younger generations remain extremely high.
Research analysed by Nurosym found that:
-
49% of Gen Z feel stressed or anxious most of the time
-
43% of Millennials report ongoing stress and anxiety
-
35% of adults aged 18 to 24 have taken time off work due to stress-related mental health issues
-
36% of younger workers feel so exhausted that they are considering leaving their jobs entirely
At the same time, constant digital stimulation is making it increasingly difficult for the nervous system to properly recover.
Many younger adults now move between constant notifications and financial pressures without meaningful periods of rest. Sustained exposure to stress can gradually keep the body locked in a heightened state of alertness.
What the Nervous System Impairment Test revealed
To better understand the biological impact of modern stress, Nurosym developed a new Nervous System Impairment Test designed to assess how lifestyle habits may be affecting nervous system function.
The test provides participants with a nervous system score out of 100, alongside personalised insights relating to areas such as sleep, autonomic balance, cognitive performance and recovery.
Early aggregated findings revealed widespread signs of nervous system strain:
-
Nearly three-quarters (73%) of participants scored 50 or below for overall nervous system function
-
Almost half (47%) scored just 2 out of 10 for autonomic nervous system balance
-
Sleep health and cognitive performance emerged among the weakest-scoring categories overall
Together, these findings suggest many people may be spending extended periods in a heightened stress state where the body struggles to properly recover.
How chronic stress may influence biological ageing
According to Dr Elisabetta Burchi, Head of Research at Nurosym, modern lifestyles are exposing younger generations to levels of nervous system stimulation that previous generations were less likely to experience.
She explains:
“The generational contrast is stark, as previous generations were less exposed to constant digital stimulation and the pressures of an always-on culture.”
The autonomic nervous system is responsible for balancing stress and recovery responses throughout the body. When stress becomes chronic, the body can remain in “fight or flight” mode for extended periods, affecting sleep, recovery, emotional resilience and cognitive performance.
Dr Burchi explains:
“When the nervous system is repeatedly activated without sufficient recovery, it loses its ability to adapt. Over time, this reduced flexibility can accelerate biological ageing and impact multiple systems, from cognition to immune function.”
Why nervous system regulation is becoming part of the longevity conversation
As conversations around burnout and stress-related ageing continue to grow, attention is beginning to shift away from surface-level wellness habits alone.
One area attracting growing interest is vagus nerve stimulation (VNS), which targets the vagus nerve, a key regulator involved in relaxation and recovery.
Nurosym is a non-invasive vagus nerve stimulation device designed to help support nervous system regulation through gentle electrical stimulation delivered via the ear.
Clinical findings have shown that vagus nerve stimulation may support:
-
up to 35% reduction in anxiety
-
48% reduction in fatigue
-
32% increase in memory recall
-
61% increase in vagus nerve activity
The future of longevity may depend on recovery
Modern wellness culture often promotes the idea that better health comes from constantly improving performance. However, our findings suggest the body’s ability to recover may be just as important.
For younger generations living under constant stimulation and pressure, chronic stress is increasingly becoming normalised, even among people who appear highly health-conscious on the surface.
As research around nervous system function continues to evolve, supporting stress regulation and recovery capacity could become increasingly important for protecting long-term health and resilience.
