Low-Dose Ozone Therapy Improves Sleep Quality in Patients with Insomnia and Coronary Heart Disease by Elevating Serum BDNF and GABA

We studied the effects of low-dose ozone therapy on the sleep quality of patients with coronary heart disease (CHD) and insomnia by measuring the levels of brain-derived neurotrophic factor (BDNF) and GABA in blood serum. The 3-month course of low-dose ozone therapy significantly elevated serum BDNF and GABA in CHD patients with insomnia and improved parameters of anxiety, depression, and sleep quality according to Hospital Anxiety and Depression Scale (HADS), Pittsburgh Sleep Quality Index (PSQI), and Self-Rating Scale of Sleep (SRSS). Ozone therapy also significantly (p<0.05) improved the total antioxidant status of the body by elevating catalase activity and reducing malondialdehyde and 8-OHdeoxyguanosine in the saliva. The serum levels of BDNF and GABA negatively and closely correlated with PSQI and HADS scores. Low-dose ozone therapy improved sleep quality and reduced PSQI and HADS scores due to up-regulation of BDNF and GABA.
