Why delay caffeine intake
Sources:
Delaying caffeine intake by 90 to 120 minutes after waking can optimize your energy levels throughout the day and help avoid the afternoon crash. explains that consuming caffeine immediately upon waking may lead to blocking adenosine receptors, causing a build-up that results in increased sleepiness later in the day 1 2. By delaying it, you allow natural processes like cortisol awakening response to take place, which optimizes wakefulness and reduces dependency on additional afternoon caffeine doses that can disrupt sleep 3 2.
Furthermore, delaying caffeine intake can help stabilize energy, maintaining a consistent arc throughout the day without experiencing significant dips or relying too heavily on caffeine, which can impact sleep quality if consumed later in the day 4 5.
