Immunity and Hyperbarics
A strong immune system depends on healthy circulation, effective white blood cell function, and adequate oxygen delivery to tissues. When oxygen levels are low, immune responses can become slower and less effective. Hyperbaric oxygen therapy (HBOT) increases the amount of oxygen dissolved in the bloodstream under pressure, allowing oxygen to reach tissues more efficiently. This enhanced oxygen environment helps support immune function and the body’s natural defense and healing processes (Thom, 2009; Heyboer et al., 2017).
1. Supporting White Blood Cell Function
White blood cells rely on oxygen to identify and destroy harmful bacteria. HBOT improves oxygen availability in tissues, which enhances the ability of immune cells especially neutrophils to fight infection effectively. Better oxygenation supports faster and more efficient immune responses (Thom, 2009).
2. Creating an Environment Less Favorable to Infection
Many harmful bacteria thrive in low-oxygen environments. By increasing tissue oxygen levels, HBOT helps create conditions that are less supportive of anaerobic bacterial growth. This oxygen-rich environment supports the body’s natural defenses and may help reduce infection risk during healing or recovery (Heyboer et al., 2017).
3. Supporting Immune Balance and Recovery
Chronic stress, illness, and injury can weaken immune regulation over time. HBOT supports healthier tissue environments and circulation, helping the immune system function more efficiently without overactivation. This balanced support is especially helpful during recovery from illness, surgery, or prolonged inflammation (Efrati & Ben-Jacob, 2014).
4. Enhancing Healing Where Immunity Is Needed Most
The immune system works hand-in-hand with tissue repair. HBOT improves oxygen delivery to areas with poor circulation, supporting faster healing and stronger immune protection in vulnerable tissues. This makes HBOT a valuable supportive therapy for individuals needing immune and healing support (Heyboer et al., 2017).
