A sleep aid is a product or substance designed to help individuals fall asleep or stay asleep more easily. These aids can come in various forms, including over-the-counter medications, prescription drugs, herbal supplements, and natural remedies. Common ingredients in sleep aids may include melatonin, diphenhydramine, or valerian root, which are known for their calming effects. While sleep aids can be effective for occasional sleeplessness, they are not a long-term solution for chronic sleep issues. It's important to consult a healthcare professional before using any sleep aid, as they can have side effects or interact with other medications. Additionally, establishing good sleep hygiene practices, such as maintaining a regular sleep schedule and creating a comfortable sleep environment, can also improve sleep quality.
