How do executives fix their sleep without supplements or wearables?
Fix the room and the timing before buying anything. Keep the bedroom at 17 to 19 degrees and blackout dark, take the phone out of the room, wake at the same time every day, have caffeine only before two and no alcohol in the last three hours. Then measure energy for two weeks.
Start with the room, not with yourself
Almost everything wrecking a founder's sleep is in the room rather than in the body. The room is also the only part you can fix tonight, for nothing, without needing a single good decision at eleven at night.
- Seventeen to nineteen degrees. Core temperature has to drop for deep sleep.
- Blackout dark. Dark enough that you cannot see your own hand. An eye mask does the same job as an expensive blind.
- Phone out of the room. Not airplane mode. Out of the room. The problem is not the notification. It is being reachable.
Fix the wake time. The bedtime follows.
- The same wake time every day, within thirty minutes. Including Saturday. Including after a bad night. The wake time anchors the whole rhythm, and bedtime is the end you control least.
- Caffeine before two, no alcohol in the last three hours. Both feel unrelated to sleep. Both decide what kind of night you get.
Why no supplements or wearables first
Melatonin, sleep stacks, blue light glasses and trackers are sold hard. None of them belong in the first fourteen days. Not because they are all useless, but because they are optimisation, and optimisation is a reward for having a floor, not a way to build one.
A supplement never substitutes for the pillar with the gap. You do not need a device to tell you that you slept badly. If you want a number, write two down.
How to know it worked
Before you change anything, score your energy at 4pm out of ten and roughly how long it takes you to fall asleep, for five days. Run the five rules for fourteen days. Score the same two again. The gap is the only proof that counts, and it belongs to you.

Short answers
Is melatonin a good idea for jet lag or bad nights?
It is not part of the first fourteen days. Fix the room, the wake time, caffeine and alcohol first. If you are considering any supplement or sleep medication, that conversation belongs with your doctor.
What if I fix all five and still sleep badly?
Then sleep may not be the starting point, or there may be a medical cause. Snoring, gasping at night or daytime sleepiness that does not lift are reasons to see your doctor. Persistent bad sleep is data, not a character flaw.
How long until I notice a difference?
Run the rules for fourteen days and compare your numbers. Some people notice within a week. The comparison matters more than the first impression.
