Insomnia affects millions of adults worldwide, with about 30% reporting short-term symptoms and roughly 10% living with chronic insomnia lasting at least 3 months. Prevalence tends to be higher in women, among older adults (ages 65+), and in shift workers, who face elevated risk. As you scroll, you’ll explore how risk factors like obesity, depression, and late caffeine interact with both health outcomes and costs.
Key Takeaways

- Benzodiazepines provide short-term insomnia relief in 70% but tolerance develops in 30% within weeks
- Polysomnography confirms insomnia diagnosis in only 20-30% with objective sleep measures
- Insomnia costs the US economy $411 billion annually in lost productivity
- Chronic insomnia leads to 11.3 extra sick days per year per affected worker
- Globally, insomnia-related healthcare costs exceed $63 billion yearly

- In the United States, about 50 to 70 million adults have sleep or wakefulness disorder, including insomnia affecting 10-15% chronically
- Globally, insomnia symptoms affect up to 40% of the population at some point, with prevalence higher in women at 23.2% vs. 19.6% in men
- Shift workers have a 1.5-2 times higher risk of insomnia compared to day workers
- Obesity increases insomnia risk by 55%, with BMI >30 associated with higher odds
- Depression is comorbid with insomnia in 75% of cases, with bidirectional risk ratio of 2.5
- Insomnia increases risk of motor vehicle accidents by 2.6 times compared to good sleepers
