Objectives: This study investigated sleeping problems in the Swedish population based on the Swedish National Board of Health and Welfare’s national patient register on numbers of patients in specialized outpatient care diagnosed with codes for sleeping problems. Methods: Numbers of patients per year and per 100,000 inhabitants in various age groups: 0–4, 5–19, 20–39, 40–59, and 60+ years diagnosed each year between 2001 and 2024 with the ICD codes G47 (sleep disorders) or F51 (non-organic sleep disorders) as main diagnosis were assessed. Results: The highest increase for sleep disorders was seen among children, adolescents, and young adults. All results are given per 100,000 persons. In the age group 0–4 years, the numbers of sleep disorders (G47) increased from 41.5 in 2001 to 215.8 in 2024. The corresponding results in the age group 5–19 years were 13.8 and 235.6, respectively. In the age group 20–39 years, 40.4 were diagnosed in 2001 and 220.9 in 2024. For subjects aged 40–59 years, 169.5 were diagnosed in 2001 and 362.8 in 2024, and for persons aged 60+ years, 116.4 were diagnosed in 2001 and 322.9 in 2024. No major changes in the numbers of persons with F51, non-organic sleep disorders, were observed. Conclusions: Sleeping problems can be caused by several factors; however, the rapid increase in recent years has temporally coincided with an increase in the public’s exposure to microwave radiofrequency (RF) radiation and increasing use of screens. RF radiation and use of screens may negatively impact sleep.
