Caffeine and Insomnia

Caffeine, found in coffee, is one of the most prevalent sleep disruptors in our lives.

It blocks adenosine, a neurotransmitter that induces drowsiness. Therefore, consuming caffeine close to bedtime can disrupt various sleep metrics, including the time it takes to fall asleep, total sleep duration, sleep quality, and the time spent in deep sleep.

But it’s not just coffee. Decaf coffee still has about 2 to 15 milligrams of caffeine per cup. Other sources like non-cola sodas, energy drinks, cacao-based products like chocolate, and some energy bars can contain caffeine or derivatives.

It’s important you know these less-known sources to ensure you sleep properly tonight. Yes — caffeine can give us that boost during the day, but let’s consume it mindfully.
