Effect of Wudhu on Sleep Quality

Sleep needs are determined by the duration (sleep quantity), depth of sleep, and what is felt after sleep (sleep quality). Many people often ignore the quantity of sleep and consider it normal when the amount of sleep is less than usual. Poor sleep quantity can cause low concentration and attention, which might result in decreased academic scores. Long-term impacts include an elevated risk of coronary heart disease, obesity, high blood pressure, diabetes, mental stress, stroke, and other causes of death. Wudhu before bed is one of the interventions to improve sleep quality. This study aimed to determine the effect of ablution before bed on the quantity of sleep in the students of the Nurul Huda Mergosono Islamic boarding school in Malang-Indonesia. The participants of this study were 82 Islamic boarding school students recruited through simple random sampling. The instrument used was the One Week Sleep Diary. Participants filled out sleep observation sheets and performed ablution for two weeks. Multiple logistic regression was used to analyze the data. In addition, this study examined factors that affect sleep quality in the broader population. The results showed that most participants had a TST of 5 hours. The participants had difficulty initiating sleep, and it took a long time to fall asleep again when they woke up from sleep at night. The most important factor affecting the quantity of sleep was carrying out ablution before going to bed. Keywords: sleep quantity, ablutions, sleep disorder
