Before we get to the fun stuff, one honest truth: real sleep problems are almost never fixed by piling up hacks. Persistent trouble falling asleep or unrefreshing sleep usually have an underlying cause. That might be anxiety, a schedule that's out of sync, sleep apnea, restless legs, reflux, or something else entirely. The path to better sleep is finding that cause and treating it.
That said, some tricks that sound too simple to work actually hold up in research. They won't replace a proper evaluation, but they can be genuinely helpful tools. Here are three of my favorites, and the science behind each one.
1. Paradoxical intention
It sounds backwards, but one of the best ways to fall asleep is to stop trying. Sleep is one of the few things in life that gets harder the more effort you put into it. Lying in bed thinking "I need to fall asleep" creates worry, and worry keeps the brain alert.
Paradoxical intention flips this. You lie in bed in the dark and gently try to stay awake without a phone or TV. That takes the pressure off, and sleep often slips in on its own. In a randomized trial, people with insomnia who used this approach had less sleep-related anxiety and less effort around sleep than those who didn't (Broomfield & Espie, 2003). It's now one of the tools sleep specialists use alongside cognitive behavioral therapy for insomnia (CBT-I).
How to use it with kids: Swap "go to sleep" for "you don't have to sleep, just rest your body." For anxious kids who lie awake worrying about falling asleep, this one small change in wording can lower the stakes in a big way.
2. A warm shower or bath before bed
Your grandmother may have been onto something. A warm bath or shower about 1 to 2 hours before bedtime can help you fall asleep faster, and the reason is temperature, not just relaxation.
Your core body temperature naturally drops in the evening and during sleep. That drop is one of the signals that tells your brain it's time to sleep. A warm shower brings blood to the skin of your hands and feet. When you step out, that heat escapes quickly and your core temperature falls, giving the natural sleep signal a boost. A 2019 review of 17 studies found that bathing in water around 104 to 109°F (40 to 42.5°C) 1 to 2 hours before bed shortened the time to fall asleep by about 10 minutes and improved sleep quality (Haghayegh et al., Sleep Medicine Reviews).
How to use it with kids: A bath fits naturally into a bedtime routine. For babies and young children, keep the water comfortably warm rather than hot, and always check the temperature first. Keep the timing consistent so the bath becomes a reliable cue that sleep is coming.
3. Imagery rehearsal for nightmares
If the same bad dream keeps coming back, you can actually rewrite it. Imagery rehearsal therapy (IRT) is simple: while awake during the day, you pick a recurring nightmare and change the story however you like. The monster turns friendly, you learn to fly, the scary hallway leads to a birthday party. Then you spend a few minutes each day picturing the new version.
This isn't just wishful thinking. In a randomized trial published in JAMA, people with chronic nightmares who practiced imagery rehearsal had far fewer nightmares and better sleep than those who didn't (Krakow et al., 2001). The American Academy of Sleep Medicine now recommends it as a treatment for nightmare disorder, and smaller studies in school-age children have shown similar benefits. Please remember this is not a substitute for treating anxiety or prior trauma.
How to use it with kids: Kids are naturally great at this. During the day (not at bedtime), ask your child to tell or draw the bad dream, then help them create a new, happier ending. Have them draw the new version and look at it or retell it for a few minutes each day. Keep the focus on the new story, not the scary details of the old one.
The bottom line
These three techniques are backed by real data, and they're easy to try tonight. But if sleep struggles last more than a few weeks, or if you notice snoring, gasping, frequent night wakings, or nightmares that are getting in the way of daytime life, talk with your pediatrician or a sleep specialist. The best sleep "hack" is still finding out what's really going on.
Sleep well my friends,
