After a Reiki Session: What to Expect

Share Questions? Write to us

Most commonly: deep sleep that night, tiredness or strong thirst, and a calm that lasts a day or two. Some people describe a mild headache, an urge to cry, or a stirred-up mood. Almost all of it settles within 24 to 48 hours. And there are kinds of discomfort that belong to a doctor, not to a Reiki practitioner.

The first few hours

Leaving a session is not like leaving the gym. There is no effect that can be measured.

What there is, is a body that spent an hour in an unusual state and is now returning to its ordinary rhythm. That return has its own texture.

Many people leave feeling as though they had slept three hours in one. Others leave awake, light, talking more than usual. Neither version is the correct one.

If you do not yet know what happens during the session itself, start with what does Reiki feel like.

What people most often report

Reaction	How common	How long it lasts	What helps
Deep sleep that night	Very common	One night	Do not force your usual schedule
Tiredness or heaviness	Common	12–24 hours	Slow down, plan nothing demanding
Thirst	Common	A few hours	Water, without overdoing it
Sustained calm	Common	1–3 days	Nothing; enjoy it
Emotion surfacing late	Frequent	Hours	Allow it, write it down if that helps
Mild headache	Less frequent	A few hours	Water, rest, low light
Needing to urinate more	Less frequent	A day	Nothing
Vivid dreams	Frequent	1–2 nights	Note them if they interest you
Nothing noticeable	Frequent	—	Not a failure

None of these reactions means "it worked better". And none of them is obligatory.

The so-called "healing crisis": what can honestly be said

In complementary therapy circles you will often hear that a "healing crisis" may follow a session: a passing worsening that supposedly shows something is moving.

Let me be as clear as I know how to be.

It is a term used within the field, not a demonstrated effect. There is no scientific evidence that discomfort after a session is proof of a healing process underway. I cannot claim that, and I will not.

What is true is that many people report a day of tiredness, emotional sensitivity or heaviness after a session, and that it almost always resolves on its own within a short time. That is a description of what people say, not an explanation of why it happens.

And one part of this idea strikes me as genuinely dangerous: using "healing crisis" to explain any symptom is the most efficient way to delay a medical consultation that is needed. If a practitioner tells you your pain is "the process working", be careful. Nobody can know that.

My position is simple. If you feel unwell, the question is not what it means energetically. The question is whether you need to see a doctor.

For the wider frame: the NCCIH notes that Reiki has not been shown to have harmful effects — and equally, there is no basis for reading later discomfort as proof that something is working.

Why I do not talk about "releasing toxins"

You will read that phrase in many places. I do not use it.

The body has organs for that: mainly the liver and the kidneys. There is no evidence that a Reiki session alters their work, and presenting post-session tiredness as "detoxification" is an invented explanation.

I prefer to say what I know: there was an hour of deep relaxation, the nervous system came down from high revolutions, and coming down sometimes feels like tiredness. That description is enough and needs no decoration.

When discomfort belongs to a doctor

This is the most important section of the article. Read it even if you skip the rest.

Seek medical attention — not an energetic explanation — if any of the following appears:

Fever, chills, or general malaise with a sense of being ill.
Chest pain, difficulty breathing, palpitations.
A severe headache, sudden or unlike the ones you know.
Dizziness with changes in vision, speech, or strength on one side of the body.
Pain that increases instead of easing, or lasts more than two or three days.
Worsening of a condition you already have or are being treated for.
Any new symptom that worries you. Your concern is reason enough.

And if thoughts of harming yourself appear, or emotional distress feels overwhelming, please seek professional help immediately: your doctor, your therapist, your local mental health line, or emergency services. That is not a pending session. It is a priority, and you deserve someone trained to be with you there.

Reiki accompanies. In an emergency, it is not what you need.

Where the limits of this practice lie is set out in full in Reiki contraindications.

Caring for yourself over the next 24 hours

No ritual, no obligations. Five simple things:

Water. Not heroic litres: just do not forget to drink.
A light meal that evening, if you can.
Do not schedule anything demanding straight afterwards. A hard meeting two hours later wastes most of the hour you just had.
Sleep as much as your body asks for. If it asks for ten hours, give it ten.
Better no alcohol that night. Not for a mystical reason: because the body is asking for rest, not for something else.

If you like writing, two lines before bed are useful. They serve later, when you want to know whether anything changed. The self-healing guide has more short practices of that kind.

What I see in my practice

There is a message I receive fairly often the next day.

The person writes to say they slept nine hours straight, that it had not happened in months, and that they woke up crying without being sad. It is almost always told with a mix of relief and puzzlement.

I interpret nothing. I tell them to rest, drink water and take the day gently. And almost always, by the second day, they write again to say they are fine.

In Medellín I always mention one practical detail: if you came by motorbike, leave slowly. I have seen people get off the table with the body still slowed down and merge into traffic on the Oriental ten minutes later. It is not a good idea. Walk a block first.

In Santa Elena the opposite happens: people stay. They sit outside, look at the forest, and drive down an hour later. That is probably the best way to end a session.

And if absolutely nothing happens?

It happens often, and it is not a problem.

Some people leave exactly as they arrived and only notice days later that they are sleeping better. Some never notice anything and decide this is not for them. Both are legitimate responses.

What I would not do is hunt for signs with a magnifying glass. The body is not sitting an exam and has nothing to prove.

When to book the next one

If you are doing a first block, weekly is the usual rhythm. It leaves time for the previous session to settle and for you to observe the days in between, which is where anything real shows.

Coming back two days later rarely adds much. Waiting three months turns every session into starting from scratch.

I set it out, research finding included and without using it as a sales argument, in how many Reiki sessions do I need.

Frequently asked questions

Is a headache after a session normal? It is less frequent than tiredness, but it happens. It is usually mild and eases within hours with water and rest. The word that matters is "mild": a severe, sudden or unfamiliar headache should not be attributed to the session. That is a matter for a doctor, without waiting to see whether it passes.

Can I exercise afterwards? You can, though most people prefer not to on the same day. If your body asks to walk, walk. If it asks for the sofa, sofa. What I do suggest is avoiding very demanding training in the hours after, especially if you leave with that pleasant heaviness many people describe.

I felt worse the next day. Does that mean it is working? No, and be wary of anyone who frames it that way. There is no evidence that feeling worse signals improvement underway. Brief, mild discomfort usually resolves on its own. Discomfort that persists, increases, or worries you deserves a medical consultation. Never the other way around.

Should I drink a lot of water afterwards? Drink normally if you are thirsty, which many people report being. There is no need to force large quantities: no physiological reason justifies it, and drinking to excess is not harmless either. The sensible version is simple: keep water nearby and pay attention to what your body asks for.

Can I take my medication as usual after a session? Yes. Continue your treatment exactly as your doctor prescribed. Reiki does not interfere with medication and is never a reason to adjust a dose or stop anything. If anyone suggests otherwise, leave that practice and mention it to your treating professional.

How long does the calm last? It varies a great deal. Most people describe one to three days of greater steadiness, tapering gradually. In processes accompanied over several weeks, that margin tends to hold better between sessions. It is not a measurable effect, but it is a fairly consistently reported experience.
