Nutrition’s Impact On Sleep

What you eat impacts how you sleep. It’s not a popular fact, we’d all rather eat whatever we want and not have any negative consequences. But unfortunately, what we eat will affect the quality of our sleep. It can be one of the reasons we wake up feeling groggy and tired, despite “getting” 8-10 hours of sleep. 

While you might be reading this and stressing about your desserts, this all starts well before it’s time for bed. It starts as early as your cup of coffee.

The average half-life of caffeine is 5 hours, which means it takes that long for half the caffeine you drank to leave your body. So your morning cup of joe is perfectly fine, but if you’re doing a double or a triple that may have some residual effects come bedtime. But that afternoon pick-me-up? Whether it’s another cup of coffee, an energy drink from a fancy can with a clever name, or even your pre-workout “whatever’s in here” powder… that’s definitely having an effect.

Now what did you have for dinner? A meal consisting of a healthy protein source (like a steak or piece of fish) will trigger your body’s natural state of rest and digest. This can help get your body for sleep. On the contrary, lots of processed carbs like pasta or bread, will set your body up for stimulation so it’s best to save those for earlier in the day.

And that sweet, sweet dessert we mentioned earlier? We don’t need to bang the “sugar is evil” drum in this edition. It’s simply gonna fall under the same category as those carbs: better off enjoyed in the middle of the day.


While these may not have any noticeable effects on your energy levels by the end of the day, especially you caffeine fiends who claim it “doesn’t affect you”, it can still interfere with your body’s ability to rest. You may be asleep, but if your cylinders are still firing internally, you’re not getting good quality sleep.
