Everyone wants to live a long healthy life, right? Well, working with your body's internal clock could help you make the most of your years.

There are a few simple things you can start doing today to help regulate your circadian rhythm, and thus improve your overall health and longevity:

  • Limit exposure to blue light from your mobile devices — try to avoid your electronics a few hours before you go to sleep.
  • Be smart about when you're drinking caffeine. Do you really need that 2 p.m. coffee? I would suggest you don't.
  • Eat healthy, nutritious meals at the right times.

What is your real age?

Curious about how well you're aging? We've created a quiz that helps to zero in on your "real age" — not your biological age. Check out an abbreviated version of the quiz below, and if you'd like to take the full assessment download the free Sharecare app to learn your RealAge.
