Nutrition and Healthy Habits: How Much Caffeine Do You Consume?

Many people depend on early-morning caffeine to “jump-start” their bodies. Others consume caffeinated beverages throughout the day when they are stressed or tired to keep their bodies alert and functioning. However, caffeinated foods and beverages should not replace the healthy habits of regular, balanced meals and snacks or adequate sleep.

Other Ways to Stay Awake During the Day

If you find yourself reaching for over 400mg of caffeine per day to stay awake and energized, try some of these healthy alternatives to caffeine:

  • Do not underestimate the power of a quality night's sleep. If you generally feel well rested in the morning, you are likely meeting your slumber needs. If not, be sure to turn the TV off before falling asleep and avoid looking at bright devices that can keep your brain waves stimulated. 
  • Another key is to maintain a consistent sleep/wake schedule even on the weekends.
  • Exercise is another way to ensure a good night’s sleep and being more awake during the day.
  • Try more natural ways to wake up.
  • Finally, go outside for brief sunshine breaks. Exposure to bright light helps regulate your body's rhythms.
