Dragging yourself out of bed after a full night’s sleep isn’t just bad luck. A leading nutritionist’s four-step evening routine addresses the hidden habits that can sabotage deep rest and morning energy.
Waking up groggy after what should be a full night’s sleep is a common complaint. For many, the problem isn’t genetics or age, but what happens in the two hours before bed. Small evening habits—often overlooked—can disrupt the body’s natural sleep rhythms and leave you feeling drained, no matter how early you turn in.
More time in bed won’t fix this kind of exhaustion. Nutritionist Javi Aoiz argues that the real key to feeling rested is what you do before you even lie down. His four-step routine, now used by many sleep specialists, starts with your phone and ends with a warm shower. The one rule he won’t bend: eat dinner 90 to 120 minutes before sleep.
"Clinical sleep guidelines consistently recommend limiting bright screens and heavy meals in the hour before bed, as both can significantly impair falling asleep and reduce sleep quality."

What you do before bed matters
Most people don’t realize how much their evening routines shape their sleep. The body’s repair systems, hormone cycles, and even immune function are all tuned by what happens in the hours before you turn out the lights. Aoiz’s approach is based on research showing that digestion, stress hormones, and melatonin production are all sensitive to evening habits. Eating late, scrolling through your phone, or sitting under harsh lights can leave you tossing and turning, then waking up feeling heavy-headed.
Major sleep organizations, including the National Sleep Foundation, warn that late-night eating and screen time are proven sleep disruptors. Your digestive system needs time to wind down, and your brain needs a break from blue light and digital noise. Even one late dinner or a few extra notifications can trigger shallow sleep and frequent awakenings. A Sutter Health review recommends finishing a substantial dinner two to three hours before bed, especially if the meal is heavy or high in fat, to avoid discomfort and reflux when you lie down.
The four-step routine
Aoiz’s method is straightforward and doesn’t require supplements or gadgets. First, two hours before bed, set your phone to "Do Not Disturb." This isn’t about cutting yourself off, but about avoiding the adrenaline rush from late messages and social feeds. Next, eat dinner 90 to 120 minutes before you plan to sleep. This gives your body time to start digesting, which helps prevent reflux, bloating, and the kind of discomfort that can break up your sleep. Many sleep experts recommend an even longer gap—two to three hours—especially after a heavy meal, since digestion slows at night and lying down too soon can make things worse. NutritionHealthInfo also stresses the importance of meal timing for better sleep.
One hour before bed, put your phone away completely. Set your alarm, answer any last messages, and move your phone out of reach. Blue light from screens directly suppresses melatonin, the hormone that helps you wind down. In the last hour, switch to warm, dim lighting and quiet activities—light reading, soft music, or a calm conversation. Just before bed, take a warm (not hot) shower to help your body shift into sleep mode.
"The physiological reason for limiting blue light in the evening is well established: exposure to blue wavelengths suppresses the natural nighttime rise in melatonin, while warmer red-toned light has a much weaker effect on this sleep hormone."

If your schedule is unpredictable—whether you’re a parent, shift worker, or late-night athlete—the main principle still applies: protect the 90- to 120-minute window between your last meal and sleep, and keep the four steps as consistent as possible. Even following some of these steps can improve sleep depth and how alert you feel in the morning.
When routine isn’t enough
Some people stick to a careful routine but still wake up at 3 a.m. or feel unrested. Chronic insomnia—trouble sleeping for more than three months—can point to deeper issues like sleep apnea, mood disorders, or circadian rhythm problems. In these cases, a good routine helps, but it’s not enough. Medical evaluation is important to rule out underlying causes and to find the right treatment, which might include cognitive behavioral therapy for insomnia (CBT-I), medication, or a sleep study.
If you want to learn more about how disrupted routines and late meals affect your body, this earlier article explains how these habits can leave you running on empty, even after a full night’s rest.
What sets Aoiz’s method apart is its focus on consistent habits, not quick fixes or trendy gadgets. The evidence is clear: when you eat dinner, when you put down your phone, and how you light your home at night all have a direct impact on how you feel in the morning. In a culture that treats sleep as an afterthought, reclaiming your evenings is the only way to reclaim your mornings.
Melatonin, the "sleep hormone," is produced naturally by the brain in response to darkness. Its release is especially sensitive to blue light from phones and tablets. While melatonin supplements are popular, most sleep experts agree that changing your evening habits—like dimming lights and limiting screens—works better for long-term sleep quality. For persistent insomnia, cognitive behavioral therapy for insomnia (CBT-I) is still the most effective approach, targeting the thoughts and routines that keep people awake.
