How to make a smell that will put a person to sleep?

To create a calming scent that promotes sleep, consider using essential oils known for their relaxing properties, such as lavender, chamomile, or bergamot. You can diffuse these oils in your bedroom or add a few drops to a warm bath before bedtime. Additionally, combining these scents with carrier oils can be used for a soothing massage. The key is to create a serene atmosphere that encourages relaxation and tranquility.
