One of the simplest ways you can improve your overall sleep health, not only on World Sleep Day, but everyday, is by being mindful about your light sources at night.

• Avoid using bright LED lighting in your home because it can interfere with sleep.
• Put away handheld, backlit electronic devices at least an hour before bed to encourage your brain to release the “sleep hormone,” melatonin.
• Finally, go to bed at a healthy hour (before midnight) so you can ensure a good night’s sleep and awaken refreshed at a healthy hour in the morning.
