To help someone fall asleep, you must first consider the type of environment that would be ideal for rest, You should start by trying to create the perfect atmosphere for sleep.

Comfortable Sleeping Temperature

The National Sleep Foundation suggests that the temperature to encourage sleep should be somewhere near 18 degrees, which is cooler than the average（平均的）room temperature for most homes. It is just cool enough to need a cover, but keep in mind that the “right” temperature for sleep can be different from person to person.

Consider Sound in the Room

Sound can affect people in different ways. Some prefer total silence and the slightest noises will keep them awake. On the other hand, some people can sleep better if there is a settled sound, such as a fan running or light music. People who like a surrounding sound may also enjoy a sleep sound machine that can provide various noises, such as gentle rainfall or low, classical music;

Create the Right Lighting

Light is one of the most important outside basics that can affect sleep. Light can trick your mind into believing that it is time to be awake. If you are trying to put someone to sleep, it is usually best to get rid of light in the room as much as possible. Hang heavy curtains over natural light sources, close the door to the bedroom, and try to avoid using a lamp or bright nightlight. Some people do sleep better if there is a weak light source that provides just enough illumination to make out surroundings as it makes them feel safe.

Make Creative Use of Movement

While most people only think of movement to help a small child sleep, repeated movement or swing may help a full-grown adult. For a less expensive choice, an indoor hammock（吊床）can be used to provide light movement while someone is going to sleep.
