Falling asleep on the couch in the evening often means your body is ready for sleep before you've gone to bed. After a long day your sleep drive is high, and a warm, dim sofa makes it easy to drift off. The catch: that doze can leave you wide awake once you finally get into bed.
Two systems decide when you feel sleepy. The first is your sleep drive. The National Institute of Neurological Disorders and Stroke (NINDS) says this drive gets stronger every hour you are awake, and that a chemical called adenosine, released from cells, helps make you feel sleepy. The second is your body clock. The Sleep Foundation explains that in the evening, melatonin rises as your body temperature drops.
By 9 or 10 p.m., both are pushing you toward sleep. Now add the couch: you're sitting still, half reclined, the lights are low and the TV is doing all the work. Nothing is keeping you alert.
Being short on sleep makes it even easier. The Sleep Foundation calls a chronic lack of sleep one of the most common causes of daytime sleepiness. If you're nodding off every evening, it's worth asking whether your nights are long enough.
Sleep doesn't only happen in bed. The Sleep Foundation notes that as we sleep, our sleep drive goes down. So a 30-minute doze on the sofa at 9 p.m. uses up some of the sleep pressure you were saving for bedtime. The Sleep Foundation also says napping too late in the day may contribute to nighttime sleep problems, and that waking from deep sleep can leave you groggy.
The result is a familiar pattern. You wake at 10:30, groggy and stiff. You brush your teeth under bright bathroom lights and walk to the bedroom. Then you lie there, suddenly awake.
Move the wind-down off the couch. Do the sleepiest part of your evening somewhere you are meant to sleep, or somewhere you're unlikely to drift off. For example, read in a chair in your bedroom with a lamp, then get into bed. Our guide on how to wind down before bed has ideas for that last hour.
Set a bedtime reminder. Put an alarm on your phone 30 to 45 minutes before bed and label it "Start getting ready." It's a cue to leave the sofa, not an order to fall asleep.
Go to bed when you're sleepy. The NHS advises only going to bed when you feel sleepy. If your eyelids are drooping at 9:45, that is your signal. Go to bed then, instead of pushing through to the end of the episode.
Do the chores first. Brush your teeth, lock up and set out tomorrow's things before you sit down for the evening. Then, when sleepiness hits, getting to bed takes one step.
Turn the TV off earlier. The NHS advises against watching TV or using devices like smartphones right before bed.
Sit up and keep a lamp on. If you want to stay up, make the couch less like a bed: sit upright, skip the blanket and the pillow, and keep a reading lamp on.
Fix the sleep debt. The Sleep Foundation suggests getting 7 or more hours each night and keeping regular sleep and wake times. If you doze every evening, an earlier bedtime may be the real fix.
If you nap, nap earlier. The Sleep Foundation says the best nap for adults is about 20 minutes and no longer than 30. A short nap after lunch is less likely to affect bedtime than a doze at 9 p.m. More in our guide to how long a nap should be.
This is an example for someone with an 11 p.m. bedtime. Shift the times to suit your own.
7:00 p.m. Dinner.
8:00 p.m. Couch time, sitting upright with a lamp on. Enjoy your show.
9:45 p.m. Phone alarm: "Start getting ready." TV off, teeth brushed, doors locked.
10:00 p.m. Dim lights. Read or listen to something calm in a bedroom chair.
10:45 p.m. or when sleepy. Into bed, lights out.
If you share a couch with a partner who always drifts off first, agree on a gentle cue, such as "bed, not sofa," so one of you doesn't spend the night there by accident.
Dozing off in the evening after a run of short nights makes sense. Frequent dozing even though you're getting enough sleep is different, and it's a good reason to see a doctor rather than guess at the cause. The Sleep Foundation says falling asleep unexpectedly or at unwanted times is different from napping and may be a sign of an underlying condition. Its guide to daytime sleepiness lists possible causes such as sleep apnea, which can break up sleep without you realizing, as well as other sleep disorders, some medicines, alcohol, and certain chronic illnesses and mental health conditions. NINDS advises seeing a doctor if you have problems sleeping or feel unusually tired during the day. And don't drive when you feel sleepy.
This is general information, not medical advice. Talk to your doctor or pharmacist about your own situation.
The couch doze uses up some of your sleep drive, so by the time you get to bed there is less pressure to sleep. The trip to bed, with bright bathroom lights and moving around, may wake you up a bit more.
An occasional doze isn't a crisis. It becomes a problem when it makes bedtime harder or happens every night. Frequent dozing despite enough sleep is worth raising with a doctor.
Sit upright with a lamp on, set an alarm to start getting ready for bed, turn the TV off earlier, and go to bed as soon as you feel sleepy.
It depends on timing and length. The Sleep Foundation suggests about 20 minutes and no more than 30, and warns that napping too late in the day may contribute to nighttime sleep problems.
