You could be the picture of perfection when it comes to eating early in the evening, not watching TV all night on the couch, and even curling up in an ideal 68-degree, batcave-like bedroom. So, why are you experiencing insomnia? Taking a closer look at nutrition research, you’ll see that what you eat before bed can play a big role in how well you hit the hay.

According to the National Sleep Foundation, “insomnia is difficulty falling asleep or staying asleep, even when a person has the chance to do so.” There’s both acute insomnia (which can occur conditionally and based on “life circumstances”) as well as chronic insomnia (which “occurs at least three nights per week and lasts at least three months”).

Both conditions can be influenced and exacerbated by environmental factors. As it turns out, it’s not just stress or blue light from your devices’ screens that can sabotage your sleep cycle. If you’re suffering from insomnia, can’t sleep soundly through the night, and can’t figure out why, look no farther than your diet.
