From: [[Physical Health#^arnold-pump-club|Arnold's Pump Club]] (April 2nd, 2024 - when to pour your first cup of coffee) ## When To Pour Your First Cup of Coffee Recently, there’s been debate whether it’s best to push back the timing of morning caffeine. But if you’re like Arnold and enjoy your coffee first thing, here’s some good news: **[New research suggests](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10930107/) that you’re not causing problems if you have coffee immediately after you get up in the morning.** Some experts have speculated that early morning coffee creates a physiological domino effect that can reduce your energy and cause the dreaded afternoon crash. As an alternative, it’s been suggested that your body could make better use of caffeine if you wait one to two hours after waking. A team of researchers analyzed more than 200 studies to answer the question. They didn’t just focus on energy levels and crashing — they examined 14 common questions, including whether caffeine dehydrates (the water in coffee offset the diuretic effect until you have more than 5 cups) or causes bone-mineral loss (it could occur in women drinking more than 4 cups per day). So when should you have your first cup? According to the current research, it appears you can choose when to take your first sip. If you feel better waiting for coffee, do what works best for you. However, despite the concerns, **little evidence suggests that delaying your coffee prevents an afternoon crash or disrupts cognitive function, energy, or sleep**.
