• At 33, Kayla Barnes-Lentz claims she has successfully reversed her biological age by 11 years through biohacking.
• She considers sleep and red light therapy her top biohacking techniques.
• Many of Barnes-Lentz’s methods for promoting longevity are experimental.

Kayla Barnes-Lentz aspires to live until the age of 150.

By her calculations regarding her “biological age,” she believes she is making significant progress. The 33-year-old owner of a longevity clinic and podcaster in Los Angeles has shared with Business Insider that biohacking has enabled her to lower her biological age by an impressive 11 years.

Unlike chronological age, biological age reflects the apparent health of cells, tissues, and organs. However, this concept remains controversial because there isn’t a clear understanding of how the human body “should” appear at any specific age.

Barnes-Lentz engages in a myriad of experimental health practices aimed at optimizing her wellness and prolonging her life. Her routine includes cold plunges, using vibration plates, and inhaling hydrated air, effectively making biohacking a daily endeavor for her.

However, among all her biohacking strategies, she especially values two approaches.

The Importance of Sleep

Barnes-Lentz emphasizes, “Sleep is the cornerstone of well-being.” She believes that going to bed early and achieving quality sleep dramatically enhances energy, focus, motivation, and overall well-being.

She and her husband, Warren Lentz, enjoy a calming evening routine that involves watching TV and relaxing together, typically retiring for the night by 8:30 PM.

Studies indicate that getting fewer than seven to eight hours of nightly sleep is linked to heightened risks of chronic illnesses such as type 2 diabetes, heart disease, and mood disorders, as well as problems with concentration and reaction times. According to a 2022 report by the Centers for Disease Control and Prevention, 36.8% of Americans admitted to sleeping less than seven hours each night.

While some biohackers might invest heavily in sleep enhancement products or technologies lacking scientific validation, Barnes-Lentz prefers simplicity. She uses an Oura ring to monitor her sleep quality while committing to a straightforward routine; she gets eight hours of sleep consistently and refrains from using her phone in bed.

Benefits of Red Light Therapy

Among her technological biohacking methods, Barnes-Lentz particularly enjoys red light therapy. Her home sauna is equipped with integrated red light features, allowing her to combine both therapies simultaneously.

She has noted that red light therapy enhances mitochondrial function—the energy-generating parts of cells—hoping it will boost her overall energy. A 2024 study published in the Journal of Biophotonics indicated that red light could improve mitochondrial performance, although conclusive evidence linking this to enhanced energy levels is still lacking.

Barnes-Lentz has also shared posts on Instagram detailing how she utilizes red light therapy to combat skin aging and inflammation.

While red light therapy shows promise for improving skin conditions like scars, acne, and wrinkles, further investigation is necessary to validate its effectiveness, according to the Cleveland Clinic.

While some invest heavily in premium red light therapy beds or frequent spas and clinics for treatments, Barnes-Lentz prefers to combine red light therapy sessions with her sauna time, which is part of her daily morning routine.
