Studies show bedwetters have similar sleep patterns to non-bedwetters.

However when arousal levels are compared, bedwetters generally do not "come to the surface" to the same level as non-bedwetters.

Treatment with a bedwetting alarm is very effective. The alarm will sound at the moment of wetting, alerting the sleeping brain. Gradually the brain is trained to respond to bladder signals and dryness results.

Even the deepest sleepers can learn to hear an alarm.

The keys are a motivation to be dry, an understanding of how the alarm can help them reach their goal, and family support.
