Effects of HBOT in Aging Support

Key Findings of the Study on Hyperbaric Oxygen Therapy (HBOT) and Aging

A 2020 study published in Aging examined the effects of hyperbaric oxygen therapy (HBOT) on telomere length and immunosenescence in isolated blood cells. Telomeres, protective caps at the ends of chromosomes, shorten with age, leading to cellular aging and dysfunction. Immunosenescence refers to the gradual deterioration of the immune system associated with aging.

Background
Aging is associated with shortening of telomeres—protective caps on chromosomes—and immunosenescence, the decline in immune system function. Telomere shortening leads to cellular aging, while immunosenescence reduces the body’s ability to fight infections and maintain overall health.

Study Design

• Participants: 35 healthy adults aged 64 and older.
• Intervention: 60 HBOT sessions over 90 days.
• Measurements: Blood samples were collected before, during, and after the sessions to assess telomere length and the prevalence of senescent immune cells.

Results

1. Telomere Elongation
   • Telomere length increased significantly across various immune cells:
     • T helper cells: 20% increase.
     • T cytotoxic cells: 38% increase.
     • Natural killer and B cells: Notable elongation.
2. Reduction in Senescent Immune Cells
   • The proportion of senescent cells decreased substantially:
     • T helper cells: 11% decrease.
     • T cytotoxic cells: 37% decrease.

Implications

• Cellular Rejuvenation: HBOT shows potential in reversing key markers of aging, such as telomere shortening and immune cell aging.
• Immune Health: A decline in senescent cells suggests an improved immune response, potentially boosting resistance to age-related diseases.

Caveats

• Further Research Needed: The long-term effects and broader clinical applications require additional studies.
• Practical Considerations: Accessibility, cost, and safety of HBOT need to be evaluated before general use as an anti-aging therapy.

Conclusion
This study highlights HBOT as a promising intervention for slowing cellular aging and enhancing immune function in older adults. While the findings are groundbreaking, further research is essential to establish its role in anti-aging therapies.
