The most effective thing you can do for someone with insomnia is help them build consistent sleep habits and create an environment that supports those habits. About 16% of adults worldwide, roughly 850 million people, live with insomnia, so this is far from uncommon. But helping someone sleep better requires more than telling them to relax. It means understanding what actually works, knowing what to avoid, and playing a specific supportive role in their daily routine.
Understand What They’re Dealing With
Insomnia isn’t just a bad night here and there. It becomes a clinical problem when someone has trouble falling or staying asleep at least three nights per week for three months or longer. Even shorter episodes lasting one to three months are considered significant. The person you’re trying to help may be dealing with racing thoughts at bedtime, waking up at 3 a.m. unable to fall back asleep, or both. Over time, this creates a cycle of anxiety around sleep itself, where the bedroom becomes a source of dread rather than rest.
It’s also worth knowing that insomnia sometimes overlaps with other sleep problems. If the person snores heavily, gasps during sleep, or wakes up feeling exhausted no matter how many hours they spent in bed, sleep apnea could be a factor. These two conditions can coexist, and treating only one won’t fix the other. If you notice these signs, gently raising the topic can be genuinely helpful.
Help Them Find the Right Treatment
The single best treatment for chronic insomnia is cognitive behavioral therapy for insomnia, commonly called CBT-I. It’s more effective than sleeping pills over the long term and doesn’t carry the same risks. A meta-analysis of 20 randomized controlled trials found that CBT-I reduced the time it takes to fall asleep by an average of 19 minutes and cut nighttime wakefulness by 26 minutes. Sleep efficiency improved by about 10%. Those numbers may sound modest on paper, but for someone lying awake for an hour every night, shaving off nearly half that time is life-changing.
CBT-I has five core components: sleep consolidation (limiting time in bed to match actual sleep time), stimulus control (using the bed only for sleep), cognitive restructuring (addressing the anxious thoughts that fuel insomnia), sleep hygiene education, and relaxation techniques. Programs typically run six to eight sessions, and improvements tend to last well beyond the treatment period, with studies showing benefits persisting for six to twelve months.
Your role here is encouragement. Many people with insomnia don’t know CBT-I exists, or they assume medication is the only option. Helping them find a trained therapist, or even a reputable online CBT-I program, can be the push they need.
Become an Active Partner in Their Routine
Research on “partner-assisted” CBT-I shows that when a partner or close family member actively participates in treatment, the person with insomnia is more likely to stick with the program. In these studies, partners learned the same concepts as the patient: they reviewed sleep diaries together, helped decide on schedule changes, identified patterns, and troubleshot problems as a team. The therapist essentially empowered the partner to provide structure and reinforcement at home.
You don’t need to be in a formal program to apply this principle. Here’s what it looks like in practice:
- Review their sleep patterns together. Ask them to track when they go to bed, when they fall asleep, and when they wake up. Look for patterns with them rather than making assumptions.
- Help enforce a consistent schedule. One of the hardest parts of insomnia treatment is sticking to a fixed wake time, even after a terrible night. You can help by getting up at the same time they do, or at least not making it easy for them to sleep in.
- Participate in wind-down routines. If they need to avoid screens for an hour before bed, join them. Read, stretch, or talk instead.
- Reinforce progress without pressure. Celebrate small wins (“You fell asleep faster last night”) without turning every morning into an interrogation about how they slept.
Optimize the Sleep Environment
The bedroom itself matters more than most people realize. Three variables have the biggest impact: temperature, light, and noise.
Most sleep research points to a cool room, generally between 60 and 67°F (15 to 19°C), as ideal. Bodies need to drop in core temperature to initiate sleep, so a warm room works against that process. If the person you’re helping tends to run hot, lighter bedding or a fan can make a real difference.
Light suppresses melatonin production, so the bedroom should be as dark as possible. Even small amounts of light from a phone charger or hallway can interfere with sleep quality. Blackout curtains or a sleep mask are simple fixes. Noise is trickier because complete silence isn’t always practical, especially in apartments or shared homes. A white noise machine or fan can mask disruptive sounds without requiring everyone in the household to tiptoe around.
If you share a bedroom with the person, your own habits directly shape their environment. Scrolling your phone in bed, watching TV, or keeping irregular hours all affect them. Adjusting your own behavior is one of the most concrete ways to help.
Address Caffeine, Alcohol, and Timing
Caffeine is the most common sleep disruptor that people underestimate. A moderate dose of 100 to 400 mg (roughly one to four cups of coffee) consumed three to six hours before bed measurably decreases sleep quality. To avoid any impact on total sleep time, research suggests stopping caffeine at least eight hours before bed. For someone with a 10:30 p.m. bedtime, that means no coffee, tea, or energy drinks after 2:30 p.m.
Alcohol is deceptive. It makes people feel drowsy, but it fragments sleep in the second half of the night, leading to lighter, less restorative rest. If the person you’re helping uses a nightcap to wind down, suggesting alternatives like herbal tea or a relaxation exercise can be more effective in the long run. You might also consider adjusting your own drinking habits around them, since it’s harder to skip a glass of wine when someone next to you is pouring one.
Know What to Avoid
Some well-intentioned advice actually makes insomnia worse. Telling someone to “just go to bed earlier” can backfire badly. Spending more time in bed while unable to sleep strengthens the brain’s association between the bed and wakefulness. Sleep restriction therapy, a core component of CBT-I, does the opposite: it limits time in bed to match the hours the person actually sleeps, then gradually expands it. If someone typically sleeps six hours, they might start with only six and a half hours in bed. This feels counterintuitive and temporarily increases daytime tiredness, but it works. Sleep restriction improves outcomes for one in every two to six patients compared to sleep hygiene advice alone.
Over-the-counter sleep aids are another common misstep. Most contain antihistamines that block alertness signals in the brain. They can cause next-day drowsiness, muddled thinking, dizziness, dry mouth, and digestive problems. About 8 out of 10 people experience a “hangover” effect the following day. Worse, the body adapts to them quickly. When someone stops taking them, their insomnia often rebounds and becomes worse than it was before. These products are designed for occasional, short-term use, not as a nightly solution. If the person you’re helping has been relying on them regularly, suggesting they explore CBT-I or talk with a provider about better options is one of the most useful things you can do.
Managing Your Own Frustration
Living with or caring about someone with insomnia can be genuinely difficult. Their irritability, daytime fatigue, and nighttime restlessness affect you too. It’s common to feel helpless or frustrated when your suggestions don’t seem to work immediately.
Keep in mind that insomnia is not a willpower problem. The person isn’t choosing to lie awake. Their nervous system has learned to be hyperaroused at bedtime, and unlearning that takes time and structured effort. Pressure to sleep, even well-meaning pressure, tends to increase the anxiety that keeps them awake. The most helpful stance is patient, consistent support: helping them maintain their routines, adjusting the shared environment, and trusting the process even when progress is slow. Small, sustained changes in daily habits produce better results than any single dramatic intervention.
