What Is Reiki? An Honest Guide (And What to Expect)

Reiki is one of those things that’s hard to describe until you’ve tried it. “Energy work” sounds either too mystical or too vague, depending on who’s reading. People who’ve never had it picture incense and chanting. People who’ve had it once tend to book a second session and stop trying to explain it to anyone else.

So in plain English: it’s a quiet, hour-long session that leaves most people feeling unusually calm, settled and clear-headed. There’s nothing dramatic about it. Nothing weird is going to happen. You don’t need to chant, breathe in any special way, or believe in anything in particular.

Here’s what’s actually going on, and what to expect if you’re considering trying one.

The short version

Reiki is a Japanese complementary therapy focused on relaxation, stress reduction and emotional wellbeing. The name comes from rei (universal) and ki (life energy). It was developed in 1922 by Mikao Usui in Japan and has been practised continuously ever since — both in the East as part of a longer wellness tradition, and in the West as a recognised complementary therapy.

During a session, the practitioner uses gentle hands-on or hands-near techniques while you lie comfortably, fully clothed. Most people describe the experience as peaceful, grounding and restorative. Some people feel warmth or a light tingling. Some drift into a half-asleep meditative state. Others just feel deeply still. None of those experiences is more “correct” than the others.

What it consistently delivers, across people who’ve tried it, is a noticeable shift towards calm. Many describe it as the first time in a long while they’ve actually switched off.

What it isn’t

Worth being clear about. Reiki isn’t:

• A medical treatment. It’s not a substitute for medical care and shouldn’t be used as one. If you have a health condition, see your GP. Reiki is complementary — it sits alongside conventional care, not instead of it.
• Religious. Despite its Japanese roots and the language around energy, Reiki itself isn’t tied to any belief system. People of any faith or none can have a session without any conflict.
• Dramatic. Nothing weird is going to happen. You won’t see visions or be asked to do anything strange. The whole experience is calm and gentle by design.
• Require you to believe in it. One of the things skeptics often discover is that the relaxation effect happens whether you’re a true believer or a quiet doubter. You don’t have to subscribe to anything to benefit from an hour of held stillness.

What about the science?

Here’s the honest position. The research on Reiki itself is mixed — some small studies show measurable effects on stress, anxiety and pain perception, others show effects no greater than relaxation alone. What’s clearer is that one hour of held, undisturbed quiet in a calm room reliably reduces cortisol, lowers heart rate and improves subjective wellbeing in almost everyone. Whether the additional effects of Reiki specifically are doing something further is an open question.

What we’d say plainly: the people who book sessions with Sean don’t come for a debate about mechanism. They come because they leave feeling better, and they keep coming back because that effect is reliable. That’s the practical reality, regardless of how you choose to explain it.

The NHS recognises Reiki as a complementary therapy and notes that it can support relaxation and stress reduction. It is not, and should not be presented as, a treatment for medical conditions.

What a session at Atlantis is like

Our co-founder Sean has been practising Reiki and meditation for over thirty years. He lived and studied in China under Master Yu Tian Jian within the Esoteric Buddhist tradition, which gives his approach a depth and quiet authority you don’t always find with shorter-trained practitioners. Sessions are private, in a peaceful room at Atlantis in Tiptree, and last around an hour.

Before

You’ll have a short, relaxed chat with Sean. He’ll explain what’s going to happen, answer any questions, and ask you a few simple ones — how you’ve been feeling, whether there’s anything specific you’d like the session to focus on, whether you’d prefer to lie down or sit. There’s no form to fill in. No clinical setup. It’s a conversation.

During

You lie down on a treatment table, with a blanket if you’d like one. Shoes off. Phone away. The room is quiet, dimly lit, with soft background sound if that suits you. Sean works calmly with hands-on or hands-near techniques, moving slowly around the body.

What you experience varies. Some people drift in and out of a very relaxed, almost meditative state. Some feel warmth in different areas, or a light tingling. Some report feeling unusually heavy or weightless. Some simply feel still in a way they haven’t for months. Some fall asleep. All of these are normal. None is “correct.”

What you won’t experience: anything that requires you to do anything. You’re not asked to focus, visualise or concentrate. The whole session is one where nothing is being asked of you.

After

Sean will give you a few quiet minutes to come back to yourself. Most people like some water and don’t want to rush straight back into a busy schedule. The calm tends to linger — many clients say their sleep is noticeably better that night, and that they wake up feeling clearer the next day.

Some people feel emotional unexpectedly after a session. That’s also normal. An hour of genuine stillness often surfaces things that the busy version of you was holding down.

Common questions from first-timers

“What if I can’t lie still for an hour?”

Almost everyone worries about this. Almost no one has the problem. By 10 minutes in, your nervous system has settled enough that the hour passes quickly. If you genuinely can’t lie down comfortably, sessions can be done seated.

“What if I’m skeptical?”

Plenty of Sean’s regular clients started skeptical. The relaxation effect doesn’t care what you believe. You’re welcome to think of it as “a quiet hour with someone who’s practised holding silence for thirty years” if that’s easier. The benefit shows up either way.

“Do I have to talk about anything?”

No. Reiki isn’t a therapy in the talking-to-someone sense. You don’t need to explain what’s going on in your life. You don’t need to share anything you’re not comfortable sharing. The brief chat at the start is just to make sure you’re comfortable, nothing more.

“How often should I come?”

That’s entirely up to you. Some people come once and that’s enough for a particular stretch of life. Some come monthly as part of their recovery routine. Some come weekly during especially demanding periods. There’s no protocol — it depends what you need.

“Can I do it if I’m pregnant / on medication / have a health condition?”

Reiki is very gentle and is generally considered safe in most circumstances, but please mention anything relevant when you book so Sean can take it into account. As above, it’s complementary — not a substitute for medical advice.

“What should I wear?”

Comfortable clothes you can lie down in. That’s it.

How Reiki differs from massage and meditation

People sometimes ask which of the three would suit them best. Quick translation:

• Massage works on muscles and soft tissue physically. You’re typically undressed, and the practitioner is actively manipulating your body. Great for muscular tension and physical recovery.
• Meditation is something you do yourself. The benefit comes from your own practice, repeated over time. Free, accessible, and powerful — but requires discipline.
• Reiki sits in between. You’re fully clothed and passive, like in meditation. But you’re being held in stillness by someone else, like in massage. You don’t have to find the calm yourself — the session brings it.

For people who want to meditate but find it hard to do alone, Reiki is often the bridge. For people who’ve done a lot of massage and want something more for the nervous system than the muscles, it’s a different kind of restoration.

What people actually say

The Reiki page includes a handful of client comments — words like “totally relaxed,” “almost euphoric,” “more like me again” come up often. The throughline isn’t anything mystical. It’s that an hour of properly held, undisturbed quiet has become genuinely rare in modern life, and people feel the absence of it long before they realise that’s what they’re missing.

One client described it as “an hour where my brain finally stopped doing the thing.” That’s probably the most honest review we’ve had.

Who tends to book a session

• People going through a stressful patch who need somewhere to land
• Anyone curious about meditation but who’d rather be guided into stillness than try to find it alone
• Members who use the gym hard and want a deeply restorative recovery experience
• People who simply want an hour where nothing is asked of them
• Adults dealing with grief, anxiety, sleep issues or a period of overwhelm
• Curious skeptics who’ve heard friends rave about it and want to find out what the fuss is

After your first session: what to expect

The hours after a Reiki session vary. Most people feel calm and slightly “floaty” for the rest of the day. Most sleep noticeably better that night. Some feel a small wave of emotion arrive a few hours after the session — this passes, and is usually the system processing things it was holding.

The next day, people often report feeling clearer, more present, less reactive. The effect is gentle but real. Some people describe the week after a session as “just slightly easier to be in.”

Practical details

A one-hour private session with Sean is £60, at Atlantis Gym & Spa in Tiptree — easy to reach from Colchester, Maldon, Witham, Kelvedon and across mid-Essex. Reiki is open to members and non-members alike. You don’t need to be a regular at the gym to book.

If you’ve been curious for a while and just haven’t got round to it, this is your gentle nudge.
