To understand the picture properly, it he...

HBOT, Mitochondria and Athletic Performance: What the Efrati Research Found, and What a Single Case Study Proved

For athletes, performance is not just about training harder.  Recovery, energy production and cellular efficiency all play a major role in how well the body adapts to exercise over time.One area receiving increasing attention is the role of mitochondria - often called the 'powerhouses' of the cell - and how Hyperbaric Oxygen Therapy (HBOT) may positively influence them.A 2022 study from Prof. Shai Efrati and colleagues explored exactly this question in middle-aged athletes.  Their find...

Post-Surgical Wound Care and the Benefits of Hyperbaric Oxygen Therapy (HBOT)

Surgical wounds are expected to progress through a normal healing process, but in some cases recovery can be delayed by factors such as reduced blood flow, swelling, infection, diabetes, smoking history, radiation injury, or extensive tissue trauma.When healing becomes compromised, oxygen delivery to the affected tissues may also decrease - and oxygen is one of the key ingredients required for tissue repair.  This is where Hyperbaric Oxygen Therapy (HBOT) plays a supportive role as an adjun...
