“…with the following response options: very good, good, bad, very bad. If the response to this question was bad or very bad, the adolescent was rated as having poor sleep quality [19] . Concerning the question, "What time do you go to bed?"…”

“…SHS [9]: The SHS is a questionnaire measuring subjective happiness comprising 4 items, self-evaluated on a 7-point scale. For example, the first item asks participants to characterize themselves using absolute ratings from "not a very happy person" (1) to "a very happy person" (7). The scores from each item were averaged into a single JSHS composite score, with higher scores demonstrating a higher level of subjective happiness.…”

“…Among health-related behaviors, sleep has been strongly correlated with happiness. Particularly, subjective happiness and positive affect have been associated with high-quality sleep and minimal sleep problems [7]. However, while the results of a systematic review on the relationship between positive affect and sleep concluded that subjective happiness and positive affect are correlated with sleep (length and quality), most of the data were from questionnaire surveys, and only 6 of 44 studies used objective sleep evaluations.…”

The objective of this study was to explore the relationship between subjective happiness and subjective and objective sleep. The participants were 24 healthy university students (11 males, 13 females; mean age 22.4 ± 2.1). Their subjective happiness was measured by the Japanese Subjective Happiness Scale (JSHS). Furthermore, their subjective and objective sleep evaluation was measured by Ogri-Shirakawa-Azumi sleep inventory MA version (OSA-MA) and a non-contact sheet sensor (SS). The results indicated that participants with higher subjective happiness had objectively shorter sleep onset latency, higher sleep efficiency, and lower heart rate during sleep. On the other hand, no such correlations were found between subjective sleep evaluation with OSA and subjective happiness. These results suggest that subjective happiness is related with the ability to more easily fall asleep and better sleep efficiency.

“…In other words, it includes the evaluation of what the individual perceives and the satisfaction and happiness she receives from them (Arslan and Fadıloğlu, 2009). Good sleep quality and fewer sleep problems have been associated with happiness and a positive impact on the adult population (Otsuka et al, 2020). Happiness has positive effects on protection from psychological disturbances, interpersonal communication, an increase of self-confidence, problem-solving, effective coping with stress, holistic thinking, and developing creativity skills (Büyükşahin et al, 2016;Unüvar et al, 2015;Temiz, 2015).…”

This study was planned in a descriptive and cross-sectional design to explore the sleep hygiene and happiness levels of university students studying in health-related departments and associated factors. The sample of the study comprised of 362 registered students at the Vocational School of Health Services between 1 and 30 January 2019, in the fall semester of 2019-2020. The "Descriptive Information Form" including socio-demographic characteristics and habits, the "Sleep Hygiene Index" and the "Oxford Happiness Questionnaire" were used to collect data. SPSS 21.0 program was used in the statistical analysis of the data. Arithmetic mean, standard deviation, minimum, maximum and percentage parameters were used in the distribution of the data. In this study, data were distributed normally, so parametric tests were used for statistical analysis. Student t-test was used for two independent variables and the One Way Anova test was used for more than two independent variables. Pearson correlation analysis was performed to examine the relationships between parameters. The study revealed that 80.9% of the students in the study were female, 62.2% lived in a state dormitory, 78.7% did not smoke, 60.5% slept an average of 6-8 hours a day, and 91.2% had no chronic disease. The mean Sleep Hygiene Index scores of smokers, men, those who studied in the anesthesia program, those stayed in the state dormitory, those who drunk caffeinated beverages after 18:00, those who slept for 8 hours or more, and those who woke up unrefreshed were found to be significantly higher (P < 0.05). It was also observed that those who woke up refreshed had a significantly higher level of happiness (P < 0.05).
