Several approaches can help with insomnia, ranging from structured behavioral therapy to simple changes in your bedroom and daily habits. The most effective long-term treatment is a form of talk therapy called cognitive behavioral therapy for insomnia (CBT-I), which improves sleep in 7 to 8 out of 10 people who try it. But depending on the severity and cause of your sleep trouble, supplements, environment changes, and sometimes short-term medication can also play a role.
CBT-I: The Most Effective Treatment
Cognitive behavioral therapy for insomnia, or CBT-I, is considered the first-line treatment for chronic insomnia. It works by retraining your brain’s relationship with sleep rather than relying on a pill. A typical course involves four to six sessions with a trained therapist, and research from Michigan Medicine shows that while sleep medications work faster, CBT-I matches their effectiveness within six to eight weeks and produces better results over the long term.
CBT-I combines several techniques:
- Stimulus control means re-pairing your bed with sleep only. You stop reading, scrolling, or watching TV in bed. If you’re lying awake for more than about 20 minutes, you get up and go to another room until you feel sleepy again. Over time, your brain relearns that bed equals sleep.
- Sleep restriction sounds counterintuitive: you temporarily limit the time you spend in bed to build stronger sleep pressure. If you’re only sleeping five hours but lying in bed for eight, your therapist might have you stay in bed for just five and a half hours at first. As your sleep becomes more consistent, you gradually add time back.
- Cognitive restructuring targets the anxiety loop that keeps many people awake. If you lie in bed dreading another sleepless night, or catastrophize about how tired you’ll be tomorrow, a therapist helps you interrupt those thought patterns and reduce the pressure you put on yourself to fall asleep.
You don’t necessarily need in-person therapy. Digital CBT-I programs exist and have shown similar results in clinical trials, making this approach accessible even if a sleep specialist isn’t nearby.
Bedroom Environment Changes
Your sleep environment has a direct effect on how quickly you fall asleep and how deeply you stay asleep. Temperature is one of the biggest factors. Sleep experts recommend keeping your bedroom between 60 and 67°F (15 to 19°C). Your body needs to drop its core temperature slightly to initiate sleep, and a cool room helps that process along. If your bedroom runs warm, even a fan or lighter bedding can make a noticeable difference.
Light matters just as much. Any light exposure in the bedroom, especially blue-toned light from screens or LEDs, suppresses your body’s natural melatonin production. Blackout curtains, covering standby lights on electronics, and keeping your phone face-down (or out of the room entirely) all help reinforce the darkness signal your brain needs. Noise is more individual. Some people sleep better with white noise or a fan to mask intermittent sounds like traffic or a partner’s snoring, while others do best in silence.
Melatonin and Other Supplements
Melatonin is the most widely used sleep supplement, but most people take too much of it too late. Your body naturally produces melatonin as darkness falls, signaling that it’s time to wind down. Supplemental melatonin works best as a timing cue rather than a sedative. Doses as low as 0.3 to 1 mg can reproduce the natural nighttime levels seen in young adults, yet most over-the-counter products contain 3 to 10 mg or more.
Timing also trips people up. Taking melatonin right at bedtime is less effective than taking it three to four hours before your desired sleep time. For most people, that means around 6:00 or 7:00 PM, not 10:00 PM. At the right dose and timing, melatonin can meaningfully reduce how long it takes to fall asleep, particularly for older adults whose natural melatonin production has declined.
Magnesium is another supplement with some evidence behind it, though the research is less robust. Studies have typically used magnesium in combination with melatonin and zinc (around 225 mg of magnesium taken an hour before bed) rather than magnesium alone, so it’s hard to isolate its individual effect. Still, many people with insomnia are mildly deficient in magnesium, and supplementation is generally low-risk. Magnesium glycinate and magnesium threonate are the forms most commonly recommended for sleep, as they’re better absorbed and less likely to cause digestive issues than magnesium oxide.
Daily Habits That Affect Sleep
What you do during the day shapes your sleep at night more than most people realize. Two biological systems control sleepiness: your circadian clock (which runs on a roughly 24-hour cycle tied to light) and sleep pressure (which builds the longer you’ve been awake). Good daytime habits support both.
Getting bright light exposure in the morning, ideally within the first hour of waking, anchors your circadian rhythm and makes it easier to feel sleepy at night. Physical activity also helps, though exercising within two to three hours of bedtime can be stimulating for some people. Caffeine has a half-life of about five to six hours, meaning half the caffeine from your 2:00 PM coffee is still circulating at 7:00 or 8:00 PM. Cutting off caffeine by noon is a common recommendation for people struggling with insomnia.
A consistent wake time is one of the simplest and most powerful tools available. Even if you slept poorly, getting up at the same time every morning strengthens your circadian clock and builds sleep pressure for the following night. Sleeping in on weekends to “catch up” feels good in the moment but can perpetuate the cycle of inconsistent sleep.
When Medication Is Appropriate
Prescription sleep medications can provide short-term relief, but they come with real trade-offs. The FDA added its most serious safety warning (a boxed warning) to several common sleep medications, including zolpidem (Ambien), eszopiclone (Lunesta), and zaleplon (Sonata), after reports of complex sleep behaviors like sleepwalking, sleep driving, and other activities performed while not fully awake. These events are rare but have resulted in serious injuries and deaths.
Sleep medications also tend to lose effectiveness over weeks to months as your body develops tolerance, and stopping them can cause rebound insomnia that feels worse than the original problem. For these reasons, most sleep specialists view medication as a bridge, something to use for a few weeks while behavioral strategies take hold, rather than a long-term solution.
Over-the-counter antihistamines marketed as sleep aids (like diphenhydramine) cause drowsiness but don’t improve sleep quality. They can leave you groggy the next day and become less effective quickly. They’re not recommended for regular use.
Matching the Approach to Your Situation
If your insomnia is recent and tied to a specific stressor (a move, a job change, a loss), environment and habit adjustments may be enough to reset your sleep within a few weeks. If you’ve been dealing with poor sleep for months or years, CBT-I is the most evidence-backed path forward, with most people seeing meaningful improvement across four to six sessions.
Melatonin is worth trying if your main issue is falling asleep at the right time, especially if you’re over 50 or your sleep schedule has shifted later than you’d like. It’s less helpful if you fall asleep fine but wake up repeatedly during the night. For that pattern, sleep restriction and stimulus control, two core CBT-I techniques, tend to be more effective because they address the fragmented sleep architecture directly rather than just the onset.
