Sleep advice gets ridiculous fast.
Special glasses.
Eight supplements.
A cooling mattress that costs more than your first car.
Meanwhile bedtime moves by three hours every night and caffeine is still happening after dinner.
I would start there.
Give your body a bedtime it can recognize
I am not saying you need to be asleep at 10:03 every night.
Life happens.
But going to bed at 10 on weekdays, 2 a.m. Friday, midnight Saturday, then trying to reset Sunday night is making the job harder.
I like a reasonably consistent window.
Same thing with wake time.
The closer the schedule is from day to day, the less guessing your body has to do about when it is supposed to be awake and when it is supposed to wind down.
Morning light is one of the cheapest things you can do
Go outside.
Actually outside.
Not standing six feet from a window while checking email.
Light early in the day helps anchor the sleep-wake rhythm.
I like this because it is simple and does not require turning sleep into another training program.
Get up.
See daylight.
Start the day.
Your room should make sleep easier
Dark helps.
Quiet helps.
A comfortable temperature helps.
None of that is exciting.
It is still where I would spend effort before getting clever.
If the room is bright, your phone is lighting up every five minutes, and you are too hot to stay asleep, a perfect nighttime routine is fighting uphill.
Caffeine timing matters more than people want it to
This is the one lifters hate.
The 4 p.m. pre-workout feels great at 4 p.m.
The problem is bedtime still exists later.
Caffeine clearance varies a lot between people, so I do not love one universal cutoff.
I do like paying attention to what happens when caffeine gets later.
If sleep gets worse every time the afternoon dose moves back, there is your experiment.
You do not need a genetic test to notice a pattern that obvious.
Late hard training can be a real schedule problem
Sometimes the only time you can train is late.
Fine.
I would rather somebody train at 8 p.m. than pretend a perfect schedule exists when it does not.
Just pay attention to what the late session does to you.
Some people finish hard training and feel ready for bed an hour later.
Other people are still wired at midnight.
If that is you, the fix may be changing session timing when possible or keeping the latest sessions from becoming the hardest work of the week.
Do not turn the last hour of the night into chaos
I am not anti-screen.
I am anti-doing five stimulating things at once and then wondering why your brain is not sleepy.
Work email.
Bright phone.
Competitive game.
Huge meal.
Pre-workout still hanging around.
Then straight into bed.
If sleep is already good, I would not manufacture rules you do not need.
If sleep is bad, simplify the last part of the night.
I would fix habits before supplements
Supplements get attention because taking something is easy.
Changing a schedule is annoying.
That does not make the supplement the bigger lever.
If bedtime is inconsistent, caffeine is late, the room is bad, and you are only giving yourself six hours in bed, I would work on those first.
Anything you take also deserves the normal caution around medications, health conditions, and individual response.
How I think about sleep inside training
One bad night is one bad night.
I do not want Mass in Motion panicking over it.
Several short nights while workload is high and performance is dropping?
Now sleep is part of a bigger recovery pattern.
That is when the data becomes more useful.
