Sleep aids are products or substances designed to help individuals fall asleep or stay asleep. They can include over-the-counter medications, prescription drugs, herbal supplements, and lifestyle changes. Common ingredients in these aids may include melatonin, diphenhydramine, or valerian root, which are known for their calming effects. While sleep aids can be effective for some people, they are not a long-term solution for sleep problems. It's important to consult a healthcare professional before using them, as they can have side effects or interact with other medications. Additionally, establishing a regular sleep routine and creating a comfortable sleep environment can also promote better sleep.
