If you love your morning coffee but still feel groggy or jittery, you’re not alone. Neuroscientist Andrew Huberman has sparked a lot of buzz by sharing science-backed tips on the best time to enjoy your daily cup. According to his research, timing your caffeine intake could make a big difference in your energy and focus.

Curious about how to get the most from your coffee? Understanding when to drink it can help you avoid the dreaded afternoon crash and boost your productivity. Let’s explore what Huberman recommends so you can start your day feeling more alert and refreshed.

Understanding Andrew Huberman’s Recommendations on Coffee Timing

Neuroscientist Andrew Huberman connects coffee timing to your body’s circadian rhythm. Huberman recommends delaying your first cup for 90 to 120 minutes after waking to allow your natural cortisol peak. Cortisol, a hormone linked to alertness, peaks soon after waking, so postponing caffeine prevents a midday energy crash.

Huberman also notes that drinking coffee too early may lead to tolerance and less effective stimulation. Waiting lets adenosine, the compound causing sleepiness, clear naturally before caffeine blocks its action. This strategy reduces grogginess and jitteriness. For afternoon energy slumps, Huberman suggests avoiding coffee after 2 p.m. to minimize sleep disruption.

The following timing recommendations summarize Huberman’s guidance:

• Wait 1.5 to 2 hours after waking before your first coffee
• Avoid morning coffee immediately upon waking
• Skip caffeine after early afternoon to support healthy sleep
• Notice reduced jitters and better performance with new timing

The Huberman Lab podcast and social media channels provide detailed scientific context for these recommendations.

The Science Behind Coffee and the Circadian Rhythm

Andrew Huberman connects coffee timing to your body’s circadian rhythm, emphasizing that when you drink coffee shapes its effects on alertness. Morning cortisol spikes and afternoon slumps play key roles in optimizing caffeine's impact.

Cortisol Levels and Morning Coffee

Cortisol, your natural alertness hormone, peaks about 30 to 45 minutes after waking according to Huberman and research published in Endocrine Reviews (2001). Coffee consumed immediately upon waking may dampen this cortisol response, reducing caffeine's energizing properties. Delaying coffee for 90 to 120 minutes after rising aligns caffeine intake with your body's decreasing cortisol and maximizes the stimulant’s effect on focus. This routine reduces chances of jitteriness and limits caffeine tolerance buildup.

Avoiding the Afternoon Slump

Caffeine timing directly impacts your afternoon energy levels. Drinking coffee too early can cause an energy crash by mid-afternoon as adenosine, the sleep-promoting molecule, accumulates. Huberman’s approach recommends consuming your first cup late in the morning to smooth natural energy dips and sustain mental clarity longer. Avoiding coffee after 2 p.m. minimizes interference with sleep cycles, as highlighted in studies from Sleep Medicine Reviews (2013), preserving your body's sleep-wake rhythm.

Best Times to Drink Coffee According to Huberman

You can align coffee intake with your body's circadian rhythm for improved alertness and minimized crashes. Neuroscientist Andrew Huberman details precise windows and strategies to help you optimize caffeine’s effects.

Optimal Morning Window

Delay your first coffee for 90 to 120 minutes after waking. Huberman links this practice to supporting your natural cortisol peak, which occurs about 30 to 45 minutes after you get up. Waiting allows cortisol to promote wakefulness without interference. For example, drinking coffee at 8:30 to 10:00 a.m. suits most who wake around 7:00 a.m. This timing reduces the likelihood of a midday energy slump, as adenosine accumulation happens later. Avoid coffee immediately upon waking, which can blunt caffeine’s effectiveness and increase the risk of jitteriness or rapid tolerance.

Coffee and Exercise Timing

Time your coffee 30 to 60 minutes before exercise to boost performance and focus, according to Huberman’s recommendations. Caffeine enhances reaction time and endurance, as observed in morning runners, mid-day gym-goers, and early afternoon cyclists. If you exercise soon after waking, consider half a cup or delay until your main morning window to minimize impact on cortisol cycles. Avoid post-2:00 p.m. coffee, especially if your goal includes maintaining proper sleep quality.

Common Mistakes People Make With Coffee Timing

• Drinking coffee immediately after waking: Many people reach for coffee within minutes of waking up, but Andrew Huberman states that this blunts the natural cortisol peak occurring 30 to 45 minutes post-wake. You enhance alertness when you delay caffeine until at least 90 minutes after waking, according to Huberman Lab podcast episodes 12 and 79.
• Consuming caffeine too late in the day: People often drink coffee after 2 p.m., but Huberman's protocols highlight that caffeine in the afternoon disrupts your natural adenosine buildup, decreasing sleep quality. Sources show caffeine’s half-life is about 5-6 hours (Journal of Clinical Sleep Medicine), so late-day coffee may harm nighttime recovery.
• Relying on coffee for the afternoon energy crash: Many grab an extra cup to fight midday fatigue, but Huberman connects this crash to adenosine accumulation worsened by early caffeine. By having coffee later in the morning, you prevent the afternoon slump that leads to further dependence.
• Drinking coffee before exercise upon waking: Some drink coffee immediately before early workouts, but Huberman recommends half a portion or delaying caffeine intake. Adapting your timing supports both the cortisol cycle and performance.
• Ignoring individual sensitivity to caffeine: People often overlook genetics or sensitivity, though Huberman suggests some metabolize caffeine slower and experience greater sleep disruption from afternoon coffee.

Practical Tips for Applying Huberman’s Advice

• Delay morning coffee

Start your morning with water or light activity instead of immediate coffee. Drink your first cup 90–120 minutes after waking to let your natural cortisol peak work, then add caffeine for a bigger alertness boost.

• Set a specific coffee window

If you wake up at 7:00 a.m., schedule coffee between 8:30 and 10:00 a.m. This window follows Huberman’s recommendation for syncing coffee with the circadian rhythm and peak productivity.

• Time pre-exercise coffee

Drink coffee 30–60 minutes before exercise to improve energy and performance. Choose water or a small coffee serving if you exercise very soon after waking, then save the main cup for later in the morning.

• Avoid late afternoon caffeine

End coffee intake by 2:00 p.m. or at least 8 hours before your planned bedtime to minimize sleep disruption. This window accounts for caffeine’s half-life and reduces risk of insomnia.

• Adjust for your caffeine sensitivity

Monitor your alertness and sleep quality. Lower your coffee quantity if you notice jitters or disrupted sleep, especially if you process caffeine more slowly than average.

• Watch out for afternoon crashes

Don’t use early morning coffee to fend off an afternoon slump. Shift your first cup later in the morning to stabilize adenosine buildup and reduce energy dips.
