What is Reiki? Reiki is a Japanese energy healing practice. A practitioner rests their hands lightly on or just above your body, and the session is built around the idea of a life force energy moving through all of us. Most people describe warmth, tingling and a deep calm. A full session runs about an hour.
That is the short answer. Below is everything else people ask, in the order they usually ask it. What the word means, where it came from, what happens in a session, what it feels like, whether it is safe, what a Reiki Master actually is, and how to learn it yourself.
What the word Reiki means
To answer what is Reiki properly, start with the name itself.
The word comes from two Japanese words. Rei, often translated as higher wisdom or higher power. Ki, meaning life force energy, the same idea the Chinese call chi and yoga calls prana.
Put together, Reiki is usually translated as spiritually guided life force energy.
The underlying idea is simple. When your life force energy runs low, you are more prone to stress and illness. When it runs strong, you cope better and feel more like yourself. A Reiki session aims to support that flow rather than to treat any specific condition.
Where Reiki came from
Reiki as we practice it today began with Mikao Usui in Japan in the early 1920s. Usui developed the system after a period of fasting and meditation on Mount Kurama, and he opened a clinic and training school in Tokyo. His student Chujiro Hayashi refined the hand positions into the sequence most practitioners still use.
Hayashi trained Hawayo Takata, a Japanese American woman who brought Reiki to Hawaii in the late 1930s. Takata went on to train 22 Masters, and nearly all Western Reiki traces back through her.
Worth knowing: the lineage is about a century old, not ancient, and the story has been retold in different versions over the years. That does not take anything away from the practice. It just means you should be cautious about anyone claiming a secret thousand year tradition.
How Reiki is said to work
This is where most explanations of what is Reiki either go vague or overclaim, so here is both halves of it.
In the traditional explanation, the practitioner acts as a channel rather than a source. They are not giving you their own energy, which is why a practitioner does not end a session drained. Practitioners describe the energy as flowing through them to wherever your body needs it. Many also work with stones alongside it, which I cover in the 12 best crystals for Reiki.
The attunement is what makes this possible. It is a short ceremony a teacher performs once per level, and it is considered the thing that opens a student’s ability to channel Reiki. After attunement the ability is permanent. You do not lose it by not using it.
Here is the honest part, and it matters more than the mystique. There is no scientific evidence for a measurable life force energy, and controlled studies have not shown Reiki outperforming placebo for treating disease. What research does consistently find is that an hour of quiet, safe, undivided attention reduces stress and anxiety measurably. That is a real effect and worth having. Treat Reiki as support for wellbeing, never as a replacement for medical care.
What happens in a Reiki session
You stay fully clothed. You lie on a treatment table, or sit in a chair if lying down is uncomfortable. Nothing is applied to your skin and there is no massage or manipulation.
The practitioner usually starts with a short conversation about how you are and what brought you in. Then they work through a sequence of hand positions, generally from the head down to the feet, resting their hands lightly on or slightly above your body for a few minutes at each position. Many practitioners also treat the back.
If you want the practical side, I have separate guides on what Reiki costs and how Reiki compares to massage. Most sessions run 60 to 90 minutes. Music is common. Talking is optional, and plenty of people drift off partway through.
Afterwards the practitioner will usually give you a moment to sit up slowly and offer water. Some will tell you what they noticed. A good practitioner will not hand you a diagnosis.
What Reiki feels like
During a session most people report some combination of the following.
- Warmth or heat where the hands rest, sometimes surprisingly strong, like a heat pack.
- Tingling or gentle pulsing, often in the hands, the feet, or the area being worked on.
- Heaviness and deep calm, the floaty state just before sleep. Falling asleep is common and completely fine.
- Emotional release, so tears, laughter, or old memories surfacing as the body lets go.
- Colors or images behind closed eyes, most often purples and blues.
- Stomach gurgling, which simply means your body has switched into rest and digest mode.
If you feel nothing at all, nothing has gone wrong. Some people are simply less aware of subtle sensation, and a first session often passes while you are busy wondering whether you are doing it right. The after effects tend to show up anyway.
Afterwards the most common reports are deep relaxation, better sleep that night, and a lighter mood for a few days. Occasionally people feel tired or emotional for a day, which practitioners call a healing response. Drink water and go gently.
The benefits people report
Reiki is not a treatment for disease, and any practitioner who tells you otherwise is overstepping. What it reliably offers is this.
- Deep relaxation and a drop in felt stress
- Better sleep, which is the single most common report
- Relief from the sense of being wound too tight
- Emotional processing, particularly during grief
- A feeling of being cared for, which is genuinely scarce and genuinely useful
You can also use Reiki outside a session, for example to cleanse a home. Hospitals in several countries now offer Reiki alongside conventional care, usually for comfort, anxiety and pain management rather than as treatment. That is the appropriate framing.
Is Reiki safe?
Yes, for almost everyone. It is non invasive, there is no pressure applied, nothing is ingested, and there are no known harmful interactions.
Two sensible cautions. First, Reiki should never replace medical treatment, and a responsible practitioner will say so unprompted. Second, if you are working through trauma, be aware that lying still under someone’s hands can surface a lot. Choose a practitioner you trust and say beforehand if you would rather they work without touch.
Reiki during pregnancy is widely considered safe and many practitioners offer it, though you should tell them you are pregnant so they can adjust positions.
What is a Reiki Master?
A Reiki Master has trained through every level up to and including the Master level. At that point they can practice Reiki on themselves and others, teach students, and perform attunements.
The title describes training and the ability to teach. It does not claim perfection, enlightenment, or special powers. Plenty of excellent practitioners never become Masters because they have no interest in teaching.
The levels work like this.
- Level 1 opens the ability to channel Reiki and focuses on self treatment. Most people can learn this in a weekend.
- Level 2 introduces the symbols and distance healing, and it is the level most practitioners work from professionally.
- Master level adds the Master symbol and the ability to attune others.
When choosing a Master to learn from, ask about their lineage, how long they have taught, and how much support you get after the course. Be wary of anyone promising Master level in a single afternoon. The attunement can be given quickly. The practice takes longer.
Can you learn Reiki online?
Yes, and this is less controversial than it used to be. Distance attunement is a standard part of Level 2 Reiki, so a teacher passing an attunement remotely is using an established method rather than cutting a corner.
Online learning suits Level 1 particularly well, because Level 1 is mostly about self treatment and you can practice on yourself the moment the course ends.
What to look for in an online course: a named teacher with a stated lineage, a real attunement rather than a video alone, written materials you keep, and somewhere to ask questions afterwards.
Time wise, Level 1 takes a weekend of study and then the practice is ongoing. Most teachers ask you to wait about three weeks between levels so the first one settles. Reaching Master level typically takes a year or more if you do it properly.

Why learn Reiki rather than only receive it
You do not have to become a practitioner to learn Reiki. Most students learn it for themselves and never treat anyone else, which is a completely legitimate reason to train.
Once attuned you can give yourself Reiki any time, and my guide to Reiki self healing techniques covers the hand positions in detail. This which changes the practice from something you book and pay for into something you have on hand. People use it on themselves before sleep, during anxious moments, and on everyday aches.
Learning it also tends to build a steadier daily habit than intending to meditate does, because the hand positions give you something concrete to do.
How to find a good practitioner
Ask what lineage they trained in and who attuned them. Ask how long a session runs and what it costs, which in most places lands between 50 and 120 for an hour. Ask whether they work with touch or just above the body, and say which you prefer.
Walk away from anyone who claims to cure disease, tells you to stop a medical treatment, diagnoses you, or pressures you into a package of sessions on the spot.
Questions about Reiki
What is Reiki in simple terms?
What is Reiki, put plainly: a Japanese energy healing practice where a practitioner rests their hands lightly on or above your body to support your life force energy. You stay fully clothed and a session usually lasts about an hour.
What does Reiki feel like?
Most people feel warmth from the practitioner’s hands, light tingling, and a heavy pleasant calm like the moments before sleep. Some feel emotional release or see colors behind closed eyes. Feeling nothing is also normal and does not mean it is not working.
Is Reiki safe?
Yes for almost everyone. It is non invasive with no pressure, nothing ingested and no known harmful interactions. It should support medical care, never replace it.
Does Reiki actually work?
There is no scientific evidence for a measurable life force energy, and studies have not shown Reiki beating placebo for treating disease. Research does consistently show that an hour of calm, focused attention lowers stress and anxiety, which is a real benefit.
What is a Reiki Master?
Someone trained through every Reiki level up to Master, who can practice, teach, and pass attunements to new students. The title reflects training and teaching ability, not perfection or special powers.
Can you learn Reiki online?
Yes. Distance attunement is a standard part of Reiki from Level 2 onward, so passing an attunement remotely uses an established method. Level 1 suits online learning especially well because it focuses on self treatment.
How long does it take to learn Reiki?
Level 1 takes about a weekend. Most teachers ask for roughly three weeks between levels so each one settles. Reaching Master level properly usually takes a year or more.
What happens in a Reiki session?
You lie fully clothed on a treatment table. The practitioner moves through a sequence of hand positions from head to feet, resting their hands lightly on or just above you for a few minutes at each. Sessions run 60 to 90 minutes.
Can Reiki be done during pregnancy?
It is widely considered safe and many practitioners offer it. Tell your practitioner you are pregnant so they can adjust the positions for comfort.
Do you have to believe in Reiki for it to work?
Practitioners generally say no, and plenty of people arrive skeptical and still report feeling calmer afterwards. Being willing to lie still for an hour matters more than belief.
The short version
So what is Reiki, in the end? A century old Japanese practice built on the idea of life force energy. A session is an hour of lying fully clothed while someone rests their hands on or above you, and most people come out calmer and sleep better that night.
The evidence supports it as stress relief rather than as medicine. Taken on those terms it is genuinely useful, and learning Level 1 means you always have it available.
