Introduction: adequate sleep is essential to maintain a healthy life. Inadequate sleep causes various health impacts. The Centers for disease control and prevention (CDCP) from the USA announced in 2015 that sleep disorders and insufficient sleep are global health epidemics. Globally, immigration has risen especially in Sweden compared to past decades. Immigration is one of the factors of social determinants of health. Since immigration show an increasing trend, it is necessary to give much attention to the sleep health of immigrants in a health science context. Aim: The main purpose of this study is to explore the prevalence and factors associated with sleep disturbances among immigrants in Sweden. Method: Cross-sectional survey study conducted by distributing self-administered questionnaires online. Results: the prevalence of sleep disturbance among immigrants in Sweden was 69.16% (n=83). The most common self-identified factors associated with sleep disturbance were stress (62.4%, n=73) as psychological factors and high room temperature (48.3%, n=58) as environmental factors Conclusion: These findings show the necessity of taking immediate action to prevent further sleep consequences and climate change effects because of the increasing immigration trend. Future research studies can focus more on interventions that could control the impact of climate change-related sleep disturbances.
