How to Improve Your Sleep Routine: Choose the Right First Step
Struggling with late nights or lying awake? Use sleep research to choose a starting point, review caffeine, and build a practical first-week plan.
You want to sleep earlier, but work and your phone keep pushing bedtime back. Monday morning still feels difficult. With so much sleep advice available, it can be hard to decide what to change first.
Start with one distinction: are you leaving too little time for sleep, or struggling to sleep despite having the opportunity? The first calls for changes to your evening schedule. Persistent insomnia calls for a different approach.
This guide draws on sleep-restriction experiments and insomnia-treatment research. You will leave with a way to choose your next step and a sample week for someone who gets up at 7 a.m.
First, identify what is keeping you from sleeping
Working until 1 a.m. and getting up at 7 a.m. leaves little opportunity for sleep. Going to bed early but spending a long time awake presents a different problem.
If your schedule cuts sleep short, start with step 1. If you keep struggling despite enough opportunity, start with step 2. Check step 3 if you drink caffeine.
1. If you cut sleep short, set an evening finish time
Protect time for sleep by deciding when work ends. Your alarm may be fixed, but some evening activities may be movable.
Feeling accustomed to short sleep does not mean performance has recovered. In Van Dongen and colleagues’ experiment, restricting time in bed to four or six hours nightly for 14 days produced accumulating cognitive deficits. Participants’ sleepiness ratings did not fully reflect that decline. Sleep-restriction experiment: Van Dongen et al., 2003
The CDC recommends at least seven hours of sleep for adults aged 18–60. Time in bed includes time awake, so a seven-hour window does not necessarily provide seven hours of sleep. CDC sleep guidance
For example, if you usually sleep from 1 a.m. to 7 a.m., try ending evening work 30 minutes earlier. Write down tomorrow’s first task and prepare what you need for the morning. Thirty minutes is a manageable starting example, not a research-established dose with a guaranteed benefit.
Find the activity that keeps delaying bedtime. If videos run on, choose an end time before watching. If chores remain, move one of them earlier.
2. If you cannot sleep despite the opportunity, ask about insomnia treatment
Persistent difficulty falling or staying asleep is a reason to ask about cognitive behavioral therapy for insomnia, or CBT-I. It addresses sleep-related behaviors and thoughts. The American Academy of Sleep Medicine strongly recommends it for adults with chronic insomnia. AASM clinical guideline, 2021
Trauer and colleagues combined 20 trials involving 1,162 adults. Compared with inactive controls, face-to-face CBT-I reduced time to fall asleep by about 19 minutes and time awake during the night by about 26 minutes. Total sleep time did not clearly increase. The review excluded insomnia accompanied by other medical, psychiatric, or sleep disorders, limiting generalization. Insomnia-treatment meta-analysis: Trauer et al., 2015
For an appointment, record when you go to bed, roughly how long you struggle to sleep, and how it affects the next day. Those details make the problem easier to discuss.

3. Review both the amount and timing of caffeine
If you drink coffee or energy drinks later in the day, record the quantity and the last serving time. Caffeine content varies with the product and serving size.
Gardiner and colleagues tested caffeine four, eight, or twelve hours before bedtime in 23 men. A single 400 mg dose affected some sleep measures even twelve hours before bed. The study detected no significant effects at 100 mg, but that does not establish a harmless dose or universal cutoff for everyone. Caffeine trial: Gardiner et al., 2025
One practical experiment is to replace a habitual late serving with a caffeine-free drink. If you usually have an energy drink at 5 p.m., try water instead and record any change in sleep. This is a personal trial, not a claim that caffeine before 5 p.m. is always fine.

This example is for someone whose evening schedule cuts sleep short. It is not a tested treatment program. If you struggle to sleep despite the opportunity, prioritize discussing that problem rather than simply extending time in bed.
| When | Action |
|---|---|
| This afternoon | Schedule an evening finish time 30 minutes earlier than usual |
| At that time | Write tomorrow’s first task and close work |
| Next morning | Note bedtime, wake time, and any difficulty sleeping |
| During the day | Note one situation where sleepiness interfered with life |
| At the weekend | Identify one activity that delayed bedtime and move it |
Add your last caffeine serving and its amount if relevant. A week of notes can help you review your schedule or explain a concern. It cannot establish a diagnosis or prove which change caused an improvement.
Common questions
Is seven hours enough for everyone?
At least seven hours is general guidance for adults aged 18–60, not everyone’s exact requirement. Consider daytime sleepiness and difficulties functioning too.
What if going to bed earlier leaves me awake?
Do not focus only on spending longer in bed. If the problem persists, discuss insomnia treatment. This guide does not provide a do-it-yourself sleep-restriction program.
Should I also take a warm bath?
It may help with falling asleep, but evidence for the one-to-two-hour timing comes from small studies. Treat it as an optional addition after addressing your main problem. Bathing review: Haghayegh et al., 2019
Does one late night mean starting over?
Keep the record and set the next evening’s finish time. The habit-planning guide includes examples for restarting.
Your next step: change one part of tonight
If time is the problem, choose when evening work ends. If persistent difficulty sleeping is the problem, record it and seek advice. Review caffeine quantity and timing where relevant.
Write one sentence naming your main difficulty. Use it to choose either a finish time for tonight or notes for a consultation.
