What effects does “long COVID” have on our bodies?

“ long “COVID-19” typically refers to post-COVID conditions. Initially, patient groups themselves coined the term “Long Covid.” The World Health Organization defines “long COVID” as symptoms that persist for at least three months after a probable or confirmed SARS‑CoV‑2 infection. , and It persists for at least two months and cannot be diagnosed or explained by any obvious underlying cause. The predominant English term is “Long Covid,” while in Chinese it is referred to as… “ Post-COVID conditions ” , abbreviated as “ long COVID-19 ”。

Main manifestations: Anxiety, depression, palpitations, chest tightness, mental fatigue, tiredness and weakness, muscle aches, and diminished or lost taste and smell, among others. Many patients experience, after recovering from COVID-19, “Brain fog” , the main manifestation is Memory impairment and cognitive dysfunction Wait.

Hypoxia It plays an important role in the pathophysiological processes of long-COVID. Systemic hypoxia may be caused by… Pulmonary injury-induced Beginning, organ-specific hypoxia can be caused by Vascular injury Cause.

Both domestically and internationally, numerous cases of post-COVID conditions have reported that hyperbaric oxygen therapy can alleviate or even cure a range of such symptoms. In real-world cases from multiple hospitals in China in 2023, hyperbaric oxygen therapy has been shown to effectively alleviate post-COVID‑19 symptoms, while also boosting immune function, enhancing metabolic capacity, and improving overall vitality.

Hyperbaric oxygen therapy increases the partial pressure and concentration of oxygen, thereby… The oxygen content in the blood increases. As a result, it significantly enhances the body’s immune function, boosts metabolism, alleviates fatigue, improves sleep quality, increases energy and concentration, and reduces psychological stress.

It demonstrates excellent rehabilitation outcomes for pulmonary damage resulting from post-COVID conditions, as well as for fatigue and weakness caused by inadequate oxygen supply due to other chronic diseases.

Body aches: The irritation of peripheral nerves by acidic metabolic byproducts is also associated with the hypersensitivity of peripheral nerves induced by viruses. Hyperbaric oxygen therapy can enhance the metabolism of acidic substances in the body and promote the repair of peripheral nerve damage, thereby alleviating muscle soreness.

Generalized weakness: Due to hypoxia in muscle tissue, viral infections that replicate within cells can impair mitochondrial function, leading to insufficient energy supply and resulting in fatigue and weakness. Hyperbaric oxygen therapy exerts beneficial effects on mitochondrial function, enhances metabolic processes, and thereby restores the body’s physical vitality. As muscle tissue hypoxia is alleviated, physical performance is improved.

“ Brain fog ” ： It rapidly increases the oxygen content in the blood by several to over tenfold, ensuring an adequate oxygen supply to brain cells and modulating cortical function, thereby restoring and enhancing memory. It also improves cerebral blood flow to ischemic regions, preserves the integrity of the brain’s microstructure, and promotes neural plasticity, ultimately enhancing cognitive function.

Decreased immunity: Hyperbaric oxygen therapy accelerates blood flow, enhancing cardiac perfusion. It improves cerebral blood supply, alleviates cerebral ischemia, and increases cerebral blood flow. By promoting circulation, it boosts overall vitality and strengthens the immune system.

Pulmonary dysfunction and decreased vital capacity: Following SARS‑CoV‑2 infection, some patients continue to experience dyspnea and shortness of breath even after recovery. Hyperbaric oxygen therapy can reduce pulmonary edema and mitigate cardiopulmonary dysfunction caused by viral infection by increasing the diffusion distance of oxygen in plasma and tissues, enhancing its diffusion rate and solubility, thereby providing rapid relief from palpitations and chest tightness.

For those who, after recovering from COVID-19, continue to experience long-term post-COVID symptoms, hyperbaric oxygen therapy can help them overcome the challenges of “long COVID” sooner.
