Hydrogen Inhalation and Blood Pressure — What a Hypertension RCT Showed
A 2022 randomised, placebo-controlled trial in Frontiers in Pharmacology tested daily low-dose hydrogen-oxygen inhalation in midlife and older adults with hypertension already on standard care. The hydrogen group showed significantly greater reductions in systolic and diastolic blood pressure than placebo, with a clean safety profile.
Red Light Therapy and Chronic Low Back Pain — What a Meta-Analysis Found
A 2022 systematic review and meta-analysis in Clinical Rehabilitation pooled randomised controlled trials of laser-based photobiomodulation in adults with chronic non-specific low back pain. The pooled analysis showed clinically meaningful pain reduction compared with control conditions, with disability outcomes pointing in the same direction.
Molecular Hydrogen and Healthy Aging — What a 2023 Mechanistic Review Reveals
A 2023 mechanistic review in Antioxidants synthesised how molecular hydrogen acts on the redox biology of ageing — from selective scavenging of the most harmful oxygen radicals to modulation of inflammation and the gut microbiome — across age-related diseases including Alzheimer’s, Parkinson’s, cancer, and osteoporosis.
Red Light Therapy and Jaw Pain (TMD) — What a Network Meta-Analysis of 27 Trials Found
A 2021 systematic review and network meta-analysis in the Journal of Oral Rehabilitation pooled 27 randomised trials covering 969 patients with temporomandibular disorder pain. Low-level laser therapy outperformed transcutaneous electrical nerve stimulation for short-term TMD pain relief, with higher-wavelength laser protocols producing the strongest effects.
Hydrogen Water and Metabolic Syndrome — What a 24-Week Randomised Trial Showed
A 2020 randomised, double-blind, placebo-controlled trial in Diabetes, Metabolic Syndrome and Obesity tested 24 weeks of high-concentration hydrogen-rich water in 60 adults with metabolic syndrome. The hydrogen group showed significantly reduced cholesterol, glucose and HbA1c, alongside improvements in inflammation and oxidative-stress biomarkers and a mild shift toward a more favourable body composition.
How Red Light Therapy Modulates the Immune System — A Comprehensive Review
A 2025 comprehensive review mapped the mechanisms by which photobiomodulation alters immune responses — from mitochondrial ATP production to macrophage polarisation and T cell regulation — with clinical evidence across rheumatoid arthritis, psoriasis, and wound healing.
Hydrogen Therapy and Alzheimer’s Disease — What the Research Shows
A 2023 review in Biomedicine & Pharmacotherapy examined hydrogen therapy across multiple mechanisms relevant to Alzheimer’s disease — from amyloid reduction and neuroinflammation to mitochondrial support. Here is what the evidence currently shows.
Red Light Therapy and Chronic Neck Pain — What a Lancet Meta-Analysis of 16 Trials Found
A 2009 systematic review and meta-analysis in The Lancet pooled 16 randomised controlled trials covering 820 patients with acute and chronic non-specific neck pain. Low-level laser therapy reduced pain by a mean 19.86 mm on the 100 mm visual analogue scale immediately after treatment compared with placebo, with significant reductions sustained out to 22 weeks of follow-up.
Hydrogen Water and Mood, Anxiety and Autonomic Balance — What a 4-Week Trial Showed
A 2017 double-blind, placebo-controlled crossover trial in Medical Gas Research tested 4 weeks of hydrogen-rich water (600 mL/day) in 26 healthy adults. Compared with placebo, participants showed significant reductions in psychological distress (K6 score) and lower resting sympathetic nerve activity — pointing to small but measurable everyday-wellbeing effects.
Red Light Therapy and COPD — What the Research Shows About Lung Inflammation and Muscle Function
A 2023 narrative review examined photobiomodulation as a complementary treatment for COPD — covering lung inflammation reduction in animal and human studies, and significant improvements in peripheral and respiratory muscle function in clinical trials.
