What Is Reiki?

Reiki is a Japanese therapeutic practice based on the channelling of vital life energy through the practitioner's hands, with the aim of promoting physical, emotional, and mental balance.

The name comes from two Japanese words joined together: rei, meaning "universal" or "spiritual", and ki, which refers to "life energy", a concept similar to chi in Chinese medicine or prana in Ayurvedic tradition. Together, they describe the foundational idea of Reiki: that universal energy flows through all living things, and that when that flow becomes blocked or disrupted, it can affect our sense of wellbeing.

In a Reiki session, a trained practitioner acts as a channel for this energy, placing their hands lightly on or just above specific areas of the body. There is no pressure, no manipulation, and no pain. Most people simply lie down, relax, and allow the session to unfold.

Where Does Reiki Come From?

Reiki was developed in Japan in the early 20th century by Mikao Usui, a spiritual teacher and practitioner who documented the system after a period of meditation and fasting on Mount Kurama.

Usui's approach drew on existing Japanese spiritual and healing traditions, incorporating specific hand positions, energy principles, and ethical guidelines. He went on to teach his method to others, and one of his students, Chujiro Hayashi, helped to formalise the practice into a structured system.

Reiki reached the West primarily through Hawayo Takata, a Japanese-American woman who trained with Hayashi in the 1930s and later brought the practice to the United States and Europe. From there, it spread globally. Today, Reiki is practised in over 100 countries and is one of the most widely recognised complementary therapies in the world, including in Portugal.

How Does Reiki Work?

Reiki works by a practitioner directing energy through their hands to support the body's own natural capacity for balance and self-regulation.

From a traditional standpoint, the practice is based on the idea that life energy flows through pathways in the body and that disruptions in this flow, caused by stress, emotional strain, or physical tension, can contribute to discomfort or a sense of being "off". A Reiki practitioner aims to identify and ease these disruptions by working with the body's energy system.

It is worth noting that, from a conventional biomedical perspective, the mechanisms behind Reiki have not been conclusively established through clinical research. What is well-documented, however, is that many people who engage in Reiki sessions report significant feelings of relaxation, reduced stress, and improved emotional clarity. Whether this is due to the specific energetic mechanisms described in Reiki tradition, or to broader relaxation responses, remains an open question, and that's perfectly fine. You're welcome to explore the practice without having to commit to any one explanation.

What Happens in a Reiki Session?

In a typical Reiki session, you lie fully clothed on a treatment table while the practitioner moves through a series of hand positions on or above your body, usually over 45 to 90 minutes.

Here's what you can generally expect:

1. Brief consultation: Your practitioner will ask about your reasons for coming, any areas of concern, and your general health. This is also your chance to ask questions.
2. Setting the space: The room will typically be quiet, softly lit, and calm. Some practitioners use gentle music or aromatherapy.
3. The session itself: You remain fully clothed and lie comfortably on a massage table. The practitioner places their hands gently on or just above your head, shoulders, chest, abdomen, legs, and feet, following a structured sequence. There is no pressure or massage.
4. Sensations you might notice: People commonly report warmth, tingling, a sense of heaviness or lightness, or simply deep relaxation. Some people fall asleep. Others experience emotional releases. There is no single "right" experience.
5. Closing and reflection: After the session, your practitioner will give you a moment to return to full alertness and may offer a brief space to share any observations.

Each practitioner brings their own approach, so it's worth reading their profile carefully before booking. On marcarterapias.pt, you can browse Reiki therapists across Portugal, including details of their training, session format, and location.

What Are the Potential Benefits of Reiki?

Many people turn to Reiki to support stress reduction, emotional processing, and a general sense of relaxation and calm, though results vary from person to person.

Reported benefits include:

• Stress reduction and relaxation: This is the most commonly cited effect and the one with the most supporting anecdotal evidence.
• Support for emotional wellbeing: Some people find Reiki helpful during periods of grief, anxiety, or burnout.
• Better sleep: Many people report improved sleep quality following sessions.
• A sense of clarity or groundedness: Particularly useful during transitions or challenging life periods.
• Complementing other treatments: Reiki is sometimes used in palliative care settings, alongside conventional treatments, to support comfort and quality of life.

Important: Reiki is a complementary practice, it is not a substitute for medical treatment or diagnosis. If you have a health condition, always consult a qualified healthcare professional. Reiki does not claim to cure or treat any medical condition.

Who Is Reiki For?

Reiki is generally considered accessible and safe for most adults, regardless of age, background, or belief system, no prior experience or specific worldview is required.

You don't need to believe in any spiritual framework to try Reiki. Many people who approach it from a secular or sceptical perspective still find value in the sessions, primarily as a structured relaxation practice. Reiki is practised in wellness centres, private clinics, and even some hospital settings across Portugal and Europe.

That said, it is always sensible to let your practitioner know about any diagnosed conditions, pregnancy, or recent surgery before beginning. And if you're unsure whether Reiki is appropriate for your specific situation, a quick conversation with your GP is a good first step.

If you're ready to explore, marcarterapias.pt lists certified Reiki practitioners throughout Portugal, from Lisbon and Porto to smaller cities and towns, making it easy to find someone near you.

The Levels of Reiki Training

Reiki practitioners are trained across a structured system of levels, each building on the previous one in depth and scope.

• Level I (First Degree): Focuses on self-healing and in-person treatment. Practitioners learn the foundational hand positions and receive their first attunement.
• Level II (Second Degree): Introduces specific symbols used to deepen or focus the energy, and includes training in distance Reiki, the practice of sending energy remotely.
• Level III / Master Level: Divided into Master Practitioner and Master Teacher, this level deepens the practitioner's own connection to the practice and, at the Teacher level, allows them to train and attune others.

When booking a session, it's helpful to know which level your practitioner has reached. Most professional therapists practising with clients will hold at least Level II certification.

How to Choose a Reiki Practitioner in Portugal

Look for a practitioner with formal training across recognised Reiki levels, clear professional standards, and transparent communication about what sessions involve.

In Portugal, Reiki is practised as a complementary therapy and is not regulated under the national health system in the same way as licensed healthcare professions. This means the quality and depth of training can vary between practitioners. Here's what to look for:

• Clear training history: Which lineage or school did they train in? How many levels have they completed?
• Professional transparency: Do they clearly state what a session involves and what it doesn't claim to treat?
• Experience and reviews: How long have they been practising? Do they have client testimonials?
• A clear intake process: A professional practitioner will ask about your health before beginning.

You can start your search on marcarterapias.pt, where practitioner profiles are designed to give you all the information you need to choose confidently.

Final Thoughts

Reiki has been practised for over a century and continues to grow in popularity across Portugal and the wider world, not because it promises miracles, but because many people genuinely find value in the calm, attentive space it creates. Whether you're drawn to it as a relaxation tool, a form of emotional support, or simply out of curiosity, it's a practice worth exploring with an open mind.

You don't need to have all the answers before your first session. Just show up, get comfortable, and see how you feel.
