Welcome back to another episode of Sleep Reimagined, where we dive deep into the science and lifestyle strategies behind truly restorative sleep. In this episode, Nyree Penn reconnects after Nyree’s inspiring trip to the Philly Sleep Conference, where she shared her expertise and learned from fellow sleep enthusiasts.
Today, we’re tackling a challenge everyone knows too well: the dreaded afternoon slump. Why do we crash in the middle of the day, even when we think we've had enough sleep? Is our 3pm coffee habit helping or hurting us? Nyree sheds light on the biological rhythms at play, the real impact of naps, and the importance of understanding what your body truly needs.
We also explore the powerful link between nutrition and sleep, why a consistent sleep schedule is more important than the specific hour you go to bed, and how chronic fatigue can signal deeper issues.

How to Overcome the Afternoon Slump and Boost Your All-Day Energy: Insights from Sleep Reimagined
Do you find yourself hitting a wall around 3 PM, reaching for coffee just to get through the rest of your day? You’re not alone. In a recent episode of the “Sleep Reimagined” podcast, sleep specialist Nyree Penn shares actionable insights on why so many people experience that dreaded afternoon slump—and what you can do to feel energized all day.
Why Do We Experience the Afternoon Slump?
Nyree explains that our bodies naturally experience a physiological dip in energy in the early afternoon. This is partly due to melatonin, the sleep hormone, peaking during this period and causing a sense of sleepiness. While many of us have normalized that groggy feeling and have even developed cultural habits—like reaching for a “cafecito” to power through—it’s not actually a healthy routine.
The key question to ask yourself: Are you actually meeting your body’s sleep needs at night, or are you masking chronic fatigue with caffeine and catnaps?
Is Napping Good or Bad?
The answer isn’t black and white. Napping can be beneficial if you’ve had a particularly tough workout or a night of missed sleep, but if you find yourself needing a nap every single day, that’s a red flag. Nyree emphasizes that habitual daytime sleepiness often points to a deeper imbalance or even underlying sleep disorders, like sleep apnea.
The Power of a Consistent Sleep Schedule
If you're constantly tired during the day, Nyree’s number one recommendation is to establish a consistent sleep schedule—even on weekends. By going to bed and waking up at the same times every day, you retrain your body’s natural rhythm (circadian rhythm) and build up what’s referred to as “sleep pressure.” This routine enables restorative REM and non-REM cycles that help you wake up refreshed and energized.
Nutrition and Sleep Go Hand-in-Hand
Sleep quality is closely tied to nutrition, yet many overlook this link. Nyree points out that 80% of our serotonin is produced in the gut and later contributes to melatonin production, directly impacting how sleepy or awake we feel. A balanced, whole-foods-based diet supports better sleep and more stable daytime energy.
Signs of Chronic Fatigue—and How to Address It
Many people have come to accept chronic daytime tiredness as normal, but persistent sleepiness is a sign that something needs to change. According to Nyree, the first step is awareness: Take a sleep quiz, monitor your habits, and assess whether you’re getting enough quality rest. If you suspect a sleep disorder like sleep apnea, seek professional help. For most, improving sleep hygiene and nutrition can make a dramatic difference in daily energy levels.
The Role of Sunlight and the Sleep Environment
Don’t underestimate the power of daylight. Exposure to natural sunlight helps regulate your circadian rhythm and boosts the production of key hormones for sleep and wakefulness. Nyree also recommends making your sleep environment as restful as possible: keep it dark, cool, and quiet, and avoid screens before bed.
Final Takeaway: Make Sleep a Priority
Nyree’s top energy ritual is simple but powerful: Stick to a consistent sleep schedule and make sleep a priority—not an afterthought. By doing so, you can bust through that afternoon slump, improve your mood, and boost your productivity without relying on stimulants.
If you struggle with chronic fatigue, don’t ignore it. Address your sleep habits and nutrition, and if needed, seek guidance from a sleep specialist. Your body—and your brain—will thank you!
