Bedwetting happens to far more people than most realize, and the first thing to know is that it’s almost never something to be embarrassed about. About 20% of children still wet the bed at age 5, and 1% to 3% of older teens do too. Adults can experience it as well, often because of an identifiable and treatable cause. What you do next depends on whether this is a one-time event, a recurring pattern, or something new that started after years of dry nights.
Clean Up Without Lasting Damage
Strip the sheets and any mattress pad immediately. The longer urine sits, the harder it is to remove the smell. Blot the mattress with a dry towel to absorb as much moisture as possible before applying any cleaner.
Enzyme-based cleaners are the most effective option for breaking down the organic compounds in urine that cause lingering odor. Products marketed for pet urine, like Nature’s Miracle or Rocco & Roxie, work just as well on human urine. Spray or pour enough to reach as deep into the mattress as the urine soaked, then let it air dry completely. For lighter spots, a spray bottle with two teaspoons of white vinegar in eight ounces of water can freshen things up. Once the mattress is fully dry, a waterproof mattress protector is worth the investment to make future cleanups much simpler.
Why It Happens in Children
Bedwetting in children under age 7 is considered a normal part of development. The brain-bladder connection that wakes you up when your bladder is full simply matures at different rates. Around 10% of seven-year-olds still wet the bed, and most grow out of it without any treatment at all. A formal diagnosis of enuresis requires episodes at least twice a week for three months or more in a child five or older.
Some children produce less of the hormone that slows urine production at night. In adults, the body typically releases more of this hormone during sleep so the bladder doesn’t fill as fast. In kids whose bodies haven’t caught up, the bladder fills to capacity while they’re in deep sleep, and the signal to wake up doesn’t get through. This is biological, not behavioral. Punishing a child for bedwetting doesn’t help and often makes the problem worse by adding stress, which can itself trigger more episodes.
Why It Happens in Adults
New-onset bedwetting in adults is different. It almost always points to something specific going on in the body. Common medical causes include urinary tract infections, diabetes (which increases urine output), obstructive sleep apnea, constipation pressing on the bladder, and neurological conditions. If you’ve been dry for years and suddenly start wetting the bed, that pattern alone is a reason to get checked out. A doctor will typically start with a urine test and a conversation about your sleep, fluid intake, and any new medications.
Sleep apnea deserves special mention because the connection isn’t obvious. When your airway is partially blocked during sleep, the resulting pressure changes in your chest cause your heart to release a hormone that ramps up urine production and suppresses the hormone that normally keeps it in check. Some people discover their bedwetting resolves entirely once their sleep apnea is treated.
Stress and Secondary Bedwetting
When bedwetting returns after six months or more of dry nights, it’s called secondary enuresis, and stress is one of the most common triggers. Research has shown that stressful life events, such as a divorce, a move, a new school, or a traumatic experience, increase the risk of relapse in children who had previously stopped wetting the bed. The stress hormone cortisol suppresses the hormone responsible for concentrating urine at night, which means the bladder fills faster during periods of high anxiety.
This can create a vicious cycle. The bedwetting itself becomes a source of shame and family tension, which increases the child’s stress, which leads to more bedwetting. Breaking that cycle starts with reassurance. Kids need to hear clearly that it’s not their fault and they’re not in trouble. Addressing the underlying stressor, whether through a calmer home environment, talk therapy, or simply time, often resolves the bedwetting on its own.
Evening Habits That Help
Several everyday foods and drinks act as bladder irritants or increase urine production, and cutting them out in the hours before bed can make a real difference. The main ones to avoid in the evening:
- Caffeine in all forms, including chocolate, tea, soda, and supplements
- Alcohol
- Carbonated drinks
- Citrus fruits and juices
- Spicy foods, tomatoes, and salsa
- High-water-content foods like watermelon, cucumbers, and strawberries
Tapering fluid intake in the two hours before bed helps as well. This doesn’t mean restricting fluids during the day. Staying well-hydrated earlier keeps you from being overly thirsty at night. A bathroom trip right before getting into bed is a simple habit that empties the bladder at the last possible moment.
Bedwetting Alarms
For children (and some adults) with persistent bedwetting, moisture-sensing alarms are considered the first-line treatment. A small sensor clips to underwear or a bed pad and triggers a sound or vibration at the first sign of wetness. The goal isn’t to wake you up in time to run to the bathroom, though that happens too. Over weeks, the alarm trains the brain to recognize the sensation of a full bladder during sleep and either hold it or wake up.
Success rates after 10 to 12 weeks range from 50% to 80%. The most effective results come from 16 to 20 weeks of consistent use, or until you’ve achieved 14 consecutive dry nights. Relapse rates run between 12% and 30% in the first six months after stopping, so patience matters. If the alarm works and then bedwetting returns, another round of alarm therapy is reasonable.
Medication Options
When lifestyle changes and alarms aren’t enough, doctors can prescribe a synthetic version of the hormone that reduces nighttime urine production. It comes as a nasal spray or a tablet that dissolves under the tongue. It’s effective for many people, but it treats the symptom rather than the underlying cause, so bedwetting often returns when the medication stops.
The most important safety concern with this medication is that it can cause dangerously low sodium levels, especially if you drink too much fluid while taking it. For this reason, fluid intake in the evening needs to be carefully limited on nights the medication is used. It’s not typically prescribed for very young children, and kidney function needs to be adequate for the drug to work safely.
Practical Steps for Tonight
If you’re dealing with bedwetting right now, whether it’s your own or your child’s, a few straightforward changes can reduce the stress and mess while you work on a longer-term solution. Use a waterproof mattress cover. Keep a spare set of sheets and pajamas within easy reach so middle-of-the-night changes are quick and low-drama. For children, disposable absorbent underwear removes the anxiety of ruining the bed and can make sleepovers possible again.
Track the frequency. Noting how many nights per week it happens, what was eaten or drunk before bed, and whether anything stressful occurred that day gives you (and a doctor, if needed) useful patterns to work with. A few weeks of notes can make the difference between guessing and knowing what’s going on.
