Have you ever dozed off on the sofa while watching TV, only to find yourself wide awake once you crawl into bed? You’re not alone. Many people wonder why sleep comes so easily in the living room but seems to disappear the moment they lie down under the covers. Scientists and sleep researchers have explored this common problem, and the answer lies in how our brains respond to environment, habit, and pressure to sleep.
One big reason is that the sofa feels casual and relaxing. When you’re on the couch watching TV or scrolling through your phone, your brain isn’t thinking “it’s time to sleep.” You’re usually relaxed, not trying too hard to fall asleep, and that’s actually helpful. Sleep scientists call this “passive sleepiness”—when you fall asleep without effort.
In contrast, going to bed is often connected with trying to fall asleep on purpose. This can create what’s called “sleep performance anxiety,” where the pressure to sleep actually keeps you awake. You may start worrying about how many hours of sleep you’ll get, especially if you have an early morning ahead. These thoughts can activate the brain and make sleep harder.
The bedroom can also act as a trigger for stress if you often have trouble sleeping there. This is called “conditioned arousal.” Over time, your brain starts to link your bed with tossing, turning, and frustration. So even when you’re tired, walking into the bedroom may lead to alertness instead of drowsiness. On the other hand, the sofa isn’t linked with these worries, so you relax more easily.
Another reason has to do with lighting and body rhythms. On the sofa, the lights and TV may help you wind down. Blue light from screens can delay sleep in some people, but for others, the familiar background noise and dim lighting signal the body to relax. In the bedroom, turning off the lights and lying in silence might make your mind race, especially if you’re prone to overthinking or anxiety.
Research also shows that habits and routines play a role. According to the American Academy of Sleep Medicine, consistent bedtime routines help the brain recognize when it’s time to sleep. If your brain isn’t trained to relax in bed—perhaps because you use the bedroom for working, worrying, or staying on your phone—it may not switch into sleep mode easily.
One more factor is something called “sleep pressure.” This is your body’s natural drive to sleep that builds the longer you’re awake. When you’re relaxing on the sofa late at night, your sleep pressure is high. That’s why you may nod off even if the TV is still on.
But when you get up, walk to your bedroom, brush your teeth, and climb into bed, you may feel more awake because that little bit of movement reduced your sleep pressure just enough to make sleep harder.
To improve your sleep, sleep researchers recommend keeping your bedroom for sleep only, avoiding phones and work in bed, and creating a bedtime routine that calms you down. If you can recreate the relaxed feeling of the sofa in your bed—by letting go of sleep pressure and not trying too hard—you may find it easier to fall asleep where you’re supposed to.
