Gen Z’s faster ageing due to cortisol: How true is that?

In recent years, there has been growing concern that Gen Z, those born roughly between 1997 and 2012, might be aging faster biologically due to elevated cortisol levels. But is this claim rooted in science, or is it a myth? The steadiness

Gen Z

were accustomed to had been completely upended by COVID-19. Relationships, healthcare, and political environments were all redesigned. Despite being young, Gen Zers have entered adulthood in a very special way—a component that might influence their perspective on aging.
Gen Zers have recently posted videos on social media sites claiming that they are frequently mistaken for older individuals. In a video that has received almost 20 million views, 26-year-old Josh Howlett asserts that he is “younger than Zendaya,” but he is frequently criticized for being older. They blame the strains in their lives for their more mature appearance. Others went on to place the blame on vaping and excessive cosmetics use.

How does high cortisol accelerate aging?

Cortisol, often called the “stress hormone,” plays a critical role in the body’s fight-or-flight response. While short bursts of cortisol can be beneficial, chronic elevation—often linked to prolonged stress—can harm health. High cortisol levels have been associated with issues like weight gain, sleep disturbances, weakened immunity, and even accelerated cellular aging through a process called “telomere shortening.” Telomeres, protective caps at the ends of chromosomes, naturally shorten with age, but stress may hasten this process.

Stress-causing factors for Gen-Z

According to Dr. Sonali Kagne, Endocrinology Consultant at Sir H. N. Reliance Foundation Hospital and Research Centre, “For Gen Z, stress is often linked to unique challenges such as academic pressure, financial instability, and constant connectivity through social media. These factors can disrupt sleep, promote poor eating habits, and lead to sedentary lifestyles, further amplifying cortisol production. However, it’s important to approach this topic with nuance. While stress can contribute to aging, it is not a sole determinant. Genetics, diet, physical activity, and overall health play significant roles.”

According to the American Psychological Association, the COVID aftermath, inflation, healthcare access, and Gen Zers’ inability to build and sustain relationships are all contributing factors to their increased stress levels. Furthermore, according to the American Psychological Association’s stress report, 74% of Gen Z isolates themselves because they have trouble relating to others. The difficulties in their lives are exacerbated by these heightened emotions of loneliness. Furthermore, while studies have linked chronic stress to accelerated aging, no conclusive evidence shows that Gen Z as a whole is aging faster than previous generations.

Healthy habits to combat stress-related aging

To combat stress-related aging, cultivating healthy habits is key. Regular exercise, mindfulness
Practices, balanced nutrition, and adequate sleep are proven ways to reduce cortisol levels.
Limiting screen time and fostering meaningful social connections can also promote mental health.
In conclusion, while chronic stress and elevated cortisol may impact aging, the idea that Gen Z is doomed to faster aging isn’t entirely accurate. Empowering this generation with tools to manage stress can help them lead healthier and more resilient lives.
