Would you like to sleep like a baby but cannot achieve this beautiful desire? Do you sometimes wake up in the middle of the night for no reason and find it difficult to sleep? You are not alone. Sadly, millions of people suffer from sleep deprivation and disorders such as sleep apnea, restless legs syndrome, REM sleep behavior disorder, insomnia, and apposite condition narcolepsy. The more adenosine accumulated in the brain during the day, the sleepier we feel at night. Caffeine is a massive risk preventing sleep because it acts as an adenosine receptor antagonist. Therefore, we feel energetic when we consume caffeine, which is great during the day but terrible at night leading to insomnia and sleep deprivation.
