Healing Is Not Always Comfortable

Can Reiki Have Negative Effects?

The short answer is yes. But probably not the way you mean. Reiki does not cause harm. It does cause temporary discomfort as part of the healing process.

People cry during Reiki. They feel tired. They have headaches. Their emotions feel raw. These are not signs that Reiki is bad. They are signs that something is shifting. Stored energy is releasing. Old patterns are breaking up.

Reiki can have temporary negative effects, but these are typically part of the healing process, not true harm. Common temporary effects include: fatigue (healing takes energy), emotional release (crying, irritability, sadness), mild headaches (energy shifts), increased thirst, vivid dreams, and temporary worsening of symptoms before improvement (healing crisis). These effects usually last 24-48 hours. Serious negative effects are extremely rare. Reiki is considered very safe. However, Reiki should never replace medical care, and delaying medical treatment is the real risk.

The Difference Between Harm and Discomfort

What Is Normal and When to Worry

There is a difference between harm and discomfort. Harm is damage. Discomfort is a sign of change. Reiki almost never causes harm. It often causes temporary discomfort.

The discomfort is usually a sign that healing is happening. Stagnant energy is moving. Stored emotions are releasing. Your body is shifting from survival mode to healing mode. That shift can feel strange, even unpleasant.

The key is duration. Normal discomfort lasts hours to a few days. If symptoms persist or are severe, see a doctor. They are likely unrelated to Reiki.

Common Temporary Effects and Why They Happen

What to expect after a Reiki session.

  • Fatigue: Your body is using energy to heal. Rest is needed.
  • Emotional release: Stored emotions (sadness, anger, joy) surface. Let them flow.
  • Headaches: Energy shifts, especially in the head area. Hydrate and rest.
  • Healing crisis: Symptoms temporarily worsen before improving. Like a fever breaking.
  • Vivid dreams: Your subconscious is processing. Normal.
  • Increased thirst: Your body needs hydration for energy flow.

The Healing Crisis Curve

Temporary worsening before improvement, a common pattern in healing.

Baseline

How you felt before Reiki.

Temporary Worsening

Healing crisis. Fatigue, emotional release, mild discomfort. Lasts hours to days.

Improvement

New baseline. Reduced symptoms. Greater well-being.

Not linear

Healing is rarely straight line. Ups and downs are normal.

It Gets Worse Before It Gets Better

Understanding the Healing Crisis

A healing crisis is a temporary worsening of symptoms after a healing session. It is common in many healing modalities, not just Reiki. Massage, acupuncture, and detox programs all report similar phenomena.

The theory is that as the body shifts into healing mode, it releases stored toxins, tensions, and emotions. This release can temporarily exacerbate symptoms before they improve. Think of a fever breaking. You feel worse right before you feel better.

A healing crisis typically lasts 24-48 hours. If symptoms persist longer or are severe, see a doctor. Do not assume every worsening is a healing crisis.

Why Crying Is Normal

Emotions Stored in the Body

Emotions are not just in your mind. They are in your body. Tension in your shoulders. A knot in your stomach. Tightness in your chest. These are physical manifestations of emotional states.

When Reiki relaxes the body, stored emotions can surface. You might cry without knowing why. You might feel anger, sadness, or unexpected joy. You might yawn, sigh, or feel tingling.

This is release. It is not a sign that something is wrong. It is a sign that something is shifting. Let it flow. Do not judge it. Do not suppress it. It will pass.

How Practitioners Understand Negative Effects

I tell clients that they might feel tired or emotional after a session. This is normal. It means something shifted. Rest, drink water, be gentle with yourself. If you feel worse for more than two days, check with your doctor. But usually, it passes quickly.

Reiki is very safe, but it is not always comfortable. Healing can be uncomfortable. The key is to distinguish between productive discomfort and true harm. Reiki almost never causes harm. But it often causes temporary discomfort as part of healing.

If you have severe symptoms, chest pain, difficulty breathing, or anything that concerns you, seek medical attention immediately. Do not assume it is just a healing crisis. Better to be safe.

  • These effects are usually signs of healing, not harm.
  • A healing crisis (temporary worsening) is common and usually passes in 24-48 hours.
  • Serious negative effects from Reiki itself are extremely rare.
  • The real risk is delaying medical care, not Reiki itself.
  • If symptoms are severe or prolonged, see a doctor.
