- Get enough sleep.
- Address medical conditions.
- Avoid alcohol before bedtime.
What happens with lack of REM sleep?
Physically, REM sleep loss is associated with increased inflammatory responses, increased risk for obesity, and memory problems. Patients with sleep apnea, which may be associated with a complete loss of REM sleep, are at increased risk for cardiovascular disease, diabetes, obesity, and depression.
What is the best treatment for insomnia in older adults?
