Routine & sleep
A day built around your body clock
This schedule isn't built from your current habits. It's what the research supports. Pick a wake time you can keep, then work towards it.
The day to aim for
Pick a wake time you can keep every day. The rest of the schedule moves with it, keeping the same spacing and a sleep window of about 8 hours.
- 6:30 AM
Wake up and get outdoor daylight
Bright morning light is the strongest signal for setting your body clock, and it helps you feel alert.[1]
- 6:45 AM
Drink water and move a little
A glass of water and a few minutes of easy movement help you wake up.
- 7:15 AM
Breakfast with protein
Including protein at breakfast helps keep you full through the morning.[13]
- 8:30 AM
Hardest focus work
Many people feel most alert in the late morning. Use this time for work that needs deep concentration.
- 12:00 PM
Midday daylight or a short walk
Daylight during the day strengthens your body clock.[1]
- 12:30 PM
Lunch — your main meal for carbohydrates
Your body handles blood sugar better earlier in the day than late in the evening.[10]
- 1:00 PM
Walk for 10 minutes after eating
A short walk after a meal lowers the rise in blood sugar.[2]
- 1:30 PM
Last caffeine of the day
A 2023 meta-analysis found that a typical cup of coffee should be finished about 9 hours before bed to avoid reducing sleep.[3]
- 3:30 PM
Good time for hard training
Strength and power tend to peak in the late afternoon. That said, training at the same time each day matters more than the exact hour.[4]
- 7:00 PM
Dinner — finish at least 3 hours before bed
Eating within 3 hours of bedtime is linked to more acid reflux.[5]
- 9:00 PM
Dim the lights and put screens away
Bright light in the evening delays melatonin, the hormone that makes you sleepy, so you fall asleep later.[6]
- 9:30 PM
Wind down
A warm shower or bath 1–2 hours before bed helps you fall asleep faster.[7]
- 10:30 PM
If you work night shifts or have a sleep disorder, your timing needs to be planned individually with a doctor.
How far is your current schedule from that?
You sleep 7.8 h
- Going to bed between 1 and 5 AM usually means little morning light and a clash with work or school hours, which leads to catch-up sleep at weekends ("social jet lag").
How to shift gradually
Aim for bed at 10:30 PM and waking at 6:30 AM. Move both 15–30 minutes earlier every 2–3 days. Get bright light when you wake, and keep lights dim after sunset.
Your body clock, relative to your wake time
These rhythms move with your schedule, age and genetics, so they're shown relative to the wake time you picked (6:30 AM) rather than as fixed clock times.

§ 01Sleep architecture
What happens while you sleep
- Light sleep (N1–N2)
- About half the night
- The bulk of sleep. Heart rate and breathing slow down, and memory processing begins.
- Deep sleep (N3)
- Mostly early in the night
- The most restorative stage. It's when growth hormone release peaks and your body does most of its physical recovery.
- REM sleep
- Longer towards morning
- Dreaming happens here, and it's important for emotional memory and learning. In men, testosterone rises during sleep and is linked to the first REM period.[12]
- The ~90-minute cycle
- 4–6 cycles a night
- You move through the stages about every 90 minutes. Cutting sleep short mostly costs you REM sleep, which is concentrated in the final cycles.
