Effect Of Bright Light Therapy on Anxiety, Depression and Quality of Life of Stroke Patients at Thai Red Cross Rehabilitation Center

Abstract

Bright light therapy has emerged as a promising approach for enhancing sleep quality and overall quality of life, particularly among stroke patients who frequently experience sleep disturbances. This study aimed to investigate the effects of bright light therapy at an intensity of 7,500 lux on anxiety, depression, and quality of life in stroke patients. Data were collected from 25 participants undergoing rehabilitation at the Thai Red Cross Rehabilitation Center over a four-week period across three time points: before therapy, during therapy, and after therapy completion. Outcomes were assessed using standardized instruments, including evaluations of anxiety and depression levels, as well as quality of life scores. Statistical analyses were performed using t-tests. The results indicated that bright light therapy significantly improved anxiety, depression, and quality of life without any severe adverse effects. These findings suggest that bright light therapy at 7,500 lux is a safe and effective strategy for promoting health outcomes among stroke patients.
