Sleep disturbances are a common problem that can affect people of all ages. They can be caused by a variety of factors, including alarms, snorers, and noises. Alarms are devices that emit a loud sound to wake someone up at a certain time. Snorers are people who make loud, disruptive noises while they sleep. Noises can come from a variety of sources, such as traffic, construction, or animals. All of these can disrupt a person's sleep and lead to sleep disturbances.
