(HealthDay News) -- Anxiety can cause or worsen sleeping problems, says the National Sleep Foundation.

If disrupted sleep due to anxiety happens, the foundation says you may want to try a few simple strategies:

• Practice meditation. Focus on your breathing.
• Add exercise to your day. Regular exercisers tend to have better sleep.
• Practice a healthy bedtime routine.
• Write to-dos down so your brain can relax.
• Steer clear of stressful activities before bed.
• If you can't fall asleep for more than 20 minutes, get out of bed and do something relaxing.
