Sedatives are medications that help calm the mind and reduce anxiety. They work by slowing down the central nervous system, which can lead to feelings of relaxation and drowsiness. Common types of sedatives include benzodiazepines and barbiturates, which are often prescribed for conditions like insomnia or anxiety disorders. While sedatives can be effective for short-term use, they may also have side effects, such as dizziness or confusion. It's important to use them under a doctor's supervision, as they can be habit-forming and may interact with other medications. Always follow medical advice when using sedatives.
