As a stimulant which affects your levels of alertness and body function, caffeine can have a disruptive effect on your sleep if ingested shortly before slumber. Difficulty falling asleep can lead to disruption of your internal clock, and affect your natural sleep patterns.
To prevent this cycle, you should avoid ingesting high levels of caffeine in the evening, such as coffee and black teas, and instead opt for low caffeine or naturally caffeine-free options.
In addition, if you are caffeine sensitive, drinking green tea before bed can affect your sleep, as it still includes low levels of caffeine. To avoid caffeine completely, herbal blends are a more suitable alternative, as they are naturally caffeine-free. Discover how much caffeine is found in a variety of beverages in our general FAQs.
