To receive distant Reiki healing you don’t have to do anything special, but it’s best to lie down and be still if possible.
The recipient and healer can agree on a time beforehand and the person receiving simply needs to sit or lie down for the specified amount of time (typically a half hour or so). The effects of distant healing are virtually no different than hands-on healing.
An experienced Reiki healer (level II or higher) can send healing energy to a person anywhere in the world no matter how far away from the healer they are. The energy transmissions in a remote session are just as strong as if they were delivered in person directly with the hands.
Distant healings are ideal for those who don’t live in a reasonable distance from a practitioner, people who don’t have the means to travel to and from a healers office, or if you don’t particularly like someone touching you, a distance healer can provide the same benefit without the need to physically touch.
