The body produces a hormone called cortisol in large quantities. It helps you wake up. When cortisol levels are high, caffeine won’t help you except by catering to your addiction. For most people, cortisol levels are highest between 8 AM and 9 AM. Instead of taking caffeine immediately after waking up, use it at around 9:30 AM for the best results.
This one may seem counterintuitive, but it does wonders for most people. The thing about caffeine is that it won’t do its job if you wait until you’re dead tired. The adenosine will connect to the brain by then, making it difficult for the caffeine to eliminate the lethargy. So, take it thirty minutes before the afternoon slump kicks in, which usually happens right after having lunch.
3.Here’s another idea! Instead of taking advantage of caffeine’s energy-boosting abilities, go for a fifteen-minute power nap right after you ingest caffeine. The body needs some time to absorb the chemical. Once you wake up, you’ll feel much more energetic because the brain clears out the adenosine by then.
