Caffeine plays a vital role in ensuring you stay awake for a long duration. Excessive caffeine makes it difficult to obtain sufficient restorative sleep. Based on science, high amounts of caffeine in coffee disrupt your sleep patterns, particularly if you’re aged. Moderate and low amounts of caffeine don’t have abrupt effects on your sleep cycles, particularly if you have self-reported insomnia or a good sleeper. Coffee is an excellent source of caffeine, but it’s also available in tea, energy drinks, cocoa, and some medications. There are some factors that’ll determine the magnitude of caffeine in affecting sleep, such as genetic and type of coffee if you’re opting for quality sleep, moderate coffee intake, or identify the suitable time for consumption.
