For patients undergoing radiotherapy, “fatigue” is a widespread yet difficult-to-resolve problem. According to oncology statistics, most patients experience significant physical decline and sleep disturbances during radiotherapy, which can even affect mood and social life. One of the main causes of these symptoms is that while radiation kills cancer cells, it simultaneously triggers intense oxidative stress in the body.
Radiation generates large amounts of reactive oxygen species (ROS). These free radicals attack the DNA and cell membranes of healthy cells, leading to side effects such as fatigue, increased inflammation, and reduced immunity.
Hydrogen, as a gas with selective antioxidant properties, can neutralize the most destructive hydroxyl radicals (•OH), thereby reducing oxidative damage. This is precisely the focus of research teams: Can hydrogen-rich water alleviate the oxidative stress caused by radiotherapy and thereby improve patients’ quality of life?
Study Background: From Fatigue to Oxidative Stress
For patients undergoing radiotherapy, “fatigue” is a common yet hard-to-solve problem. According to oncology statistics, the majority of patients experience significant physical decline and sleep disturbances during radiotherapy, which can even affect mood and social life. One of the primary causes of these symptoms is that while radiation kills cancer cells, it simultaneously triggers intense oxidative stress in the body.
Radiation generates large amounts of reactive oxygen species (ROS). These free radicals attack the DNA and cell membranes of healthy cells, leading to side effects such as fatigue, increased inflammatory responses, and reduced immunity.
Hydrogen, as a gas with selective antioxidant properties, can neutralize the most destructive hydroxyl radicals (•OH), thereby reducing oxidative damage. This is the key focus of research teams: Can hydrogen-rich water alleviate the oxidative stress caused by radiotherapy and thereby improve patients’ quality of life?
This study enrolled 49 patients with malignant liver cancer undergoing radiotherapy and employed a randomized placebo-controlled trial design to ensure objectivity.
Patients consumed hydrogen-rich water daily, produced using hydrogen water sticks from Friender Company, maintaining a concentration of 0.55–0.65 mM.
The research team used the Korean version of the European Organisation for Research and Treatment of Cancer QLQ-C30 questionnaire to assess overall quality of life, covering multiple dimensions including physical function, emotional state, pain, appetite, and fatigue.
At the same time, researchers measured free radical metabolites and antioxidant capacity in the patients’ blood to objectively determine whether hydrogen truly reduces oxidative damage.
Study Methodology: Rigorously Designed to Validate the Effects of Hydrogen
Study Results: Significant Improvement in Quality of Life
After a six-week observation period, the results were encouraging.
Compared with the control group, patients drinking hydrogen-rich water showed a marked decrease in reactive oxygen species metabolites in their blood, while their antioxidant capacity was preserved. More importantly, during radiotherapy, the quality-of-life scores of the hydrogen-water group were significantly higher than those of the control group.
This means hydrogen-rich water not only helps patients reduce fatigue and discomfort caused by radiotherapy but also brings noticeable overall improvement in daily life: better sleep, more stable mood, and faster physical recovery.
Notably, the study also confirmed that hydrogen-rich water does not compromise the tumor-control efficacy of radiotherapy itself. In other words, while hydrogen’s antioxidant action alleviates side effects, it does not weaken radiation’s ability to kill cancer cells — a finding of great clinical importance for both physicians and patients.
Safety and Application Potential of Hydrogen-Rich Water
For cancer patients, safety is always the top priority when considering any new therapy. Hydrogen excels in this regard — it is natural, non-toxic, and free of side effects. Hydrogen molecules are extremely small, freely penetrating cell membranes and the blood-brain barrier, and are metabolised solely into water, placing no burden on the body.
Clinically, hydrogen can be administered in multiple ways: inhalation of hydrogen gas, drinking hydrogen-rich water, or intravenous hydrogen saline. Among these, drinking hydrogen-rich water is the easiest for patients to accept due to its simplicity, safety, and stability.
The findings of this study have positioned hydrogen-rich water as a low-risk, high-potential adjuvant therapy.
Scientific Controversy Worth Noting
Of course, scientific research always leaves room for discussion. Experts reviewing this study have raised a valid question: since radiotherapy kills tumor cells largely through free radicals, if hydrogen neutralizes free radicals, could it also weaken radiotherapy’s destructive effect on the tumor?
The current explanation is that **radiotherapy acts primarily in the local high-dose irradiated area, whereas the antioxidant effect of hydrogen-rich water is systemic and at relatively low concentration, insufficient to protect tumor cells in the intensely irradiated zone.
In real-world observations, hydrogen-rich water did not compromise tumor shrinkage or treatment response; instead, it successfully alleviated systemic side effects. This remains a topic deserving further research, but the present results already carry important clinical implications.
Patient Insight: From “Just Getting Through It” to “Living Better”
For every cancer patient, treatment is not only about extending life — it is about how to live better. Many patients who have participated in similar studies or used hydrogen products report that during treatment, fatigue decreased, appetite improved, sleep got better, and mood became more stable.
These changes may seem small, but for someone enduring radiotherapy or chemotherapy, they represent tremendous hope.
Hydrogen-rich water is not a miracle cure for cancer — it is an adjuvant approach that helps patients reduce suffering and regain control over their lives.
Future Outlook
The Korean study has a limited sample size and can only be regarded as a preliminary conclusion. However, it opens the door for hydrogen applications in clinical oncology and provides a valuable reference for larger-scale clinical trials in the future.
As research into hydrogen medicine deepens, people are beginning to realise that the hydrogen molecule is not merely an energy material — it may also be a natural guardian against oxidative stress in the human body.
In the future, hydrogen-rich water could become part of integrated cancer care, helping patients reduce side effects, accelerate recovery, and reclaim dignity and strength while living with the disease.
Conclusion
Hydrogen-rich water brings new hope to liver cancer patients undergoing radiotherapy. It is safe, low-risk, easy to use, and has been preliminarily proven in clinical practice to improve quality of life. Although more clinical data are still needed for full validation, this discovery undoubtedly opens a new chapter in cancer adjuvant therapy.
Warm Reminder: Hydrogen is not a medicine and cannot replace standard medical treatment. If you wish to try hydrogen-rich water or related adjuvant approaches, please do so only under the guidance of a professional physician.
