The best bedtime routine for adults who can't sleep
Most bedtime routine advice reads like a spa brochure. Light candles, drink herbal tea, do yoga, journal for twenty minutes, meditate, apply seventeen products, lie in the dark thinking beautiful thoughts. Nobody with a job, a family and actual responsibilities does this.
A useful bedtime routine for adults is one you will actually stick to. It needs to be short enough to fit into a real evening, flexible enough to survive a bad day, and built on sleep science rather than Instagram aesthetics. Here is how to put one together.
Why routines work (the science in 30 seconds)
Your brain runs on associations. If you do the same things in the same order before bed every night, your brain learns that this sequence means "sleep is coming." After a couple of weeks the routine itself starts triggering drowsiness, even before you get into bed.
Sleep researchers call this "stimulus control." It is one of the core principles of cognitive behavioural therapy for insomnia (CBT-I), the most effective non-drug treatment for chronic insomnia. The routine trains your brain to associate specific behaviours and environments with sleep, reversing the association many insomniacs have built between their bed and lying awake worrying.
The 90-minute wind-down window
You do not need a two-hour elaborate ritual. Most of the physiological preparation for sleep happens in the 60 to 90 minutes before you get into bed. Build your routine into this window and protect it.
Here is a framework you can adapt. Assume a target bedtime of 10:30pm and adjust to yours.
At about 9pm, stop working. Close the laptop. This is the hardest step for most people and the most important one. Your brain needs a clear signal that the productive part of the day is over. If you work right up until bedtime, your brain is still in problem-solving mode when you switch the light off, which is exactly how racing thoughts at night start.
Around 9:30pm, take a warm shower or bath. The temperature change triggers a core body temperature drop that initiates sleep. A 2019 meta-analysis in Sleep Medicine Reviews confirmed this works best at 40 to 42.5 degrees Celsius, taken 1 to 2 hours before bed.
From 9:45pm, switch to low stimulation activities. A physical book, a podcast, light stretching, conversation. The key is avoiding anything that produces a dopamine spike: social media, news, gaming, work email.
At 10pm, take your supplements if you use them. Magnesium glycinate taken 30 to 60 minutes before bed gives your body time to absorb it. Spray your pillow with lavender spray or start a diffuser.
At 10:15pm, get into bed. Do a brain dump if you need to (write down anything still on your mind), then lights off.
The best supplements for sleep: what actually works
Supplements are one piece of the routine, not a replacement for it. Here is what has evidence behind it and what does not.
Magnesium glycinate is the most well-supported supplement for sleep. It is involved in melatonin production, GABA regulation and nervous system relaxation. A 2012 RCT showed significant improvements in insomnia scores with 500mg daily. We compare the best UK options in our magnesium for sleep guide.
Lavender has moderate evidence for sleep quality improvement, primarily through anxiety reduction. The This Works Deep Sleep Pillow Spray is the bestseller in the UK, containing lavender, camomile and vetivert. A 2012 study found lavender inhalation improved sleep quality in women with insomnia. Whether it is the pharmacology or the consistent scent-sleep association, many people find it helps.
CBD oil has become hugely popular for sleep in the UK. TRIP Dream Drops (3000mg, with chamomile) and Goodrays Night Drops (1000mg, peppermint) are the two most popular options on Amazon UK. The evidence for CBD and sleep is mixed: it may reduce anxiety, which can improve sleep indirectly, but direct sleep-promoting effects are less established than for magnesium. It is worth trying if anxiety is a major component of your sleep problem, but manage expectations.
Chamomile tea has been drunk before bed for centuries and has mild sedative properties. A 2017 RCT found that chamomile extract improved sleep quality in elderly participants. It is not going to knock you out, but it is a pleasant ritual that fits naturally into a wind-down routine.
Melatonin is a prescription-only medicine in the UK at all doses. There is no legal over-the-counter option. It can be prescribed by a GP for specific conditions, but you cannot buy it as a supplement. If you have heard about it helping with jet lag or shift work, that is true in countries where it is available OTC, but the UK is not one of them.
Valerian root has inconsistent clinical evidence. Some trials show modest benefit, others show none. If you have tried it and it works for you, keep using it. If you have not tried it, start with magnesium instead.
What to cut from your evening
Sometimes what you stop doing matters more than what you start doing.
Screens within 30 minutes of bed are the biggest saboteur. A 2026 Land of Beds survey of 2,004 UK adults found 91% admit to using screens before bed. The blue light suppresses melatonin production, but the bigger problem is content. Social media is designed to trigger engagement (read: anxiety, comparison, outrage). News is designed to trigger alarm. Gaming triggers adrenaline. None of these are compatible with winding down.
If you cannot give up your phone entirely, switch to a paper book, a podcast (with a sleep timer) or, at minimum, enable a blue light filter and avoid social media and news.
Caffeine after 2pm affects sleep more than most people realise. Caffeine has a half-life of about 5 to 6 hours, meaning half the caffeine from a 3pm coffee is still in your system at 9pm. Individual sensitivity varies, but if you are struggling with sleep, cutting caffeine after lunch is one of the highest-impact changes you can make.
Alcohol disrupts sleep architecture even in moderate amounts. A glass of wine may help you fall asleep, but it suppresses REM sleep, causes fragmented sleep in the second half of the night and often leads to early-morning waking. If you drink, try to stop at least 3 to 4 hours before bed.
Heavy meals within 2 hours of bed force your body to divert energy to digestion when it should be winding down. A light snack is fine. A full dinner at 10pm is not.
Building your personal routine
Not every element needs to be in your routine. Pick the three or four things that fit your life and do them consistently. Consistency matters far more than comprehensiveness.
A minimal effective routine might look like this:
- 9:30pm: Close laptop, take magnesium
- 10:00pm: Warm shower, get into bed
- 10:15pm: Read for 15 minutes, lavender spray, lights off
A more thorough version for someone with significant anxiety:
- 9:00pm: Close laptop, 15-minute structured worry time with a bedtime journal
- 9:30pm: Warm shower, take magnesium, start diffuser
- 9:45pm: Get into bed under weighted blanket, read
- 10:00pm: Lavender spray, five-minute brain dump, lights off
- If thoughts race: cognitive shuffling (pick a word, visualise random objects for each letter)
The routine itself will feel awkward for the first week. By the second week it starts to feel natural. By the third or fourth week, your brain begins anticipating sleep at the start of the sequence rather than the end.
When a routine is not enough
If you have been following a consistent routine for four to six weeks with no improvement, it is worth seeing your GP. Persistent insomnia that does not respond to sleep hygiene measures may need CBT-I (available on the NHS, more effective than sleeping pills for long-term outcomes) or investigation for underlying conditions like sleep apnoea, restless leg syndrome or thyroid disorders.
A routine is a foundation. For many people it is the only intervention they need. For others it is the base on which more targeted treatment is built.
Frequently asked questions
What are the best supplements for sleep in the UK? Magnesium glycinate has the strongest evidence. Lavender pillow spray and chamomile tea have moderate evidence. CBD oil may help with anxiety-related sleep issues. Melatonin is prescription-only in the UK at all doses.
How long does a bedtime routine take to work? Most sleep researchers say two to three weeks of consistent use before the routine itself starts triggering drowsiness. Individual results vary, but consistency is the main factor.
Is it bad to read in bed? No, as long as it is a physical book or an e-reader without a backlight. Reading is one of the best low-stimulation wind-down activities. Avoid reading on a phone or tablet, and avoid thrillers or anything that keeps you turning pages until midnight.
What time should I go to bed? Whatever time gives you 7 to 9 hours before your alarm, accounting for the 15 to 20 minutes it takes most people to fall asleep. Consistency matters more than the specific time. Going to bed at 10:30 every night is better than alternating between 10pm and midnight.
