Hyperbaric oxygen therapy (HBOT) may influence hormone balance through several physiological mechanisms, primarily through its effects on oxygenation, inflammation, and potentially on the endocrine system directly. Although the direct evidence connecting HBOT to hormone balance is still emerging, we can hypothesize its potential effects based on its known physiological impacts:

Improved Oxygenation

HBOT involves breathing pure oxygen in a pressurized environment, significantly increasing the amount of oxygen dissolved in the blood. This enhanced oxygenation can improve the function of all body tissues, including those of the endocrine glands responsible for hormone production. Better oxygenated tissues may function more efficiently, potentially leading to a more balanced production of hormones.

Decrease in Inflammation

One of the key benefits of HBOT is its ability to reduce inflammation throughout the body. Chronic inflammation can interfere with hormone production and balance in several ways:

  • Interference with Hormone Production: Inflammation can disrupt the normal functioning of endocrine glands. For example, inflammation in the thyroid gland can lead to imbalances in thyroid hormones, while pancreatic inflammation can affect insulin production.

  • Impairment of Hormone Receptor Sites: Inflammation can damage or interfere with hormone receptor sites on cell membranes, making them less responsive to hormonal signals. This means that even if hormone levels are adequate, their ability to elicit the desired response in target tissues might be compromised.


By reducing inflammation, HBOT may help restore the normal sensitivity of hormone receptors, allowing hormones to bind more effectively and elicit their intended responses. This can lead to improved metabolic functions, better stress hormone regulation, and overall hormone balance.

Enhanced Tissue Repair and Regeneration

HBOT's ability to promote tissue repair and regeneration may also support the healing of damaged endocrine tissues, potentially restoring their ability to produce hormones at optimal levels.

Potential Direct Effects on Hormones

While less is known about the direct effects of HBOT on specific hormones, the therapy's general benefits to body physiology, including enhanced cellular function and reduced oxidative stress, could indirectly support the balance and effectiveness of hormones like insulin, cortisol, thyroid hormones, and sex hormones such as testosterone and estrogen.

It's important to note that the research on HBOT's effects on hormone balance, particularly regarding the optimization of hormone receptor function through decreased inflammation, is still in the early stages. The hypothesis that HBOT can improve hormone receptor sensitivity by reducing inflammation is grounded in the therapy's known physiological effects rather than direct evidence of such outcomes.
