What is the 2 hour coffee rule?
Quick answer: The 2 hour coffee rule suggests waiting at least two hours after waking up before drinking your first cup of coffee. This guideline aligns with the body’s cortisol levels, aiming to optimize both the effects of caffeine and the body’s natural wakefulness cycle. The Science Behind Caffeine and Cortisol Your cortisol levels naturally peak about 30-45 minutes after you wake up. Drinking coffee right away can interfere with this natural process, leading to a less effective wake-up call. Dr. Brooks explains, “Cortisol is released when the body needs energy.According to emerging research in circadian biology and neuroscience, waiting about 90 minutes before having caffeine can improve focus, mood, and nighttime sleep quality. It’s not about giving up your morning brew — just about timing it to align with your body’s natural cortisol rhythm.On average, most people should stop drinking caffeine four to six hours before bed. People who are especially sensitive to this stimulant may want to stop earlier in the day or avoid caffeine altogether.The 3:1 coffee hack is a way to manage increased caffeine tolerance.

What is the golden rule of coffee?
Thankfully, coffee experts around the world have figured out a tried-and-true, gold standard ratio: 1:17. It stands for 1 gram of coffee for every 17 grams of water. If you want a “stronger” cup of coffee, adding more coffee beans may not actually help. Instead, opt for a darker roast for more full-bodied flavor. The best answer is: 10 grams of ground coffee per 180 ml of water (180g of water). This requires a scale, which is a worthwhile investment if you care about the quality of your coffee, but a lot of people just want to keep things simple.
