What Happens During an iRest Yoga Nidra Session: A Military-Tested Protocol

Before You Arrive

Wear comfortable, loose clothing that won't restrict your breathing as you lie down for 20-45 minutes. Avoid heavy meals for two hours beforehand, though a light snack is fine. You might want to use the toilet before starting, as the session encourages deep relaxation that you won't want to interrupt.

Bring a water bottle for afterwards, as some people feel slightly dehydrated following deep states of rest. If you're attending a group session, arrive 10 minutes early to settle in and ask any questions. Many practitioners find it helpful to set a quiet intention about what they'd like from the practice, though this isn't mandatory.

Avoid caffeine for several hours before your session if possible. The protocol works best when your nervous system isn't artificially stimulated. If you're taking medication for anxiety or sleep, continue as prescribed — iRest is designed to complement medical treatment, not replace it.

The Session Itself

You'll lie down on a yoga mat or comfortable surface, often with a bolster under your knees and a blanket for warmth. Unlike traditional yoga classes, there's no physical movement once you're settled. The teacher will guide you through the 10-step iRest protocol using a specific, standardised script.

The session begins with setting an intention, followed by identifying your 'heartfelt desire' — something you genuinely want in your life. You'll then establish an 'inner resource', a felt sense of wellbeing or safety that you can return to if the practice becomes challenging. These opening steps typically take 5-10 minutes.

The middle portion focuses on systematic body awareness, noticing sensations without trying to change them. You'll then observe your breath naturally, again without controlling it. The teacher guides you to 'welcome' whatever feelings, emotions, thoughts, and beliefs arise — the core principle that distinguishes iRest from relaxation techniques.

The final steps invite you to welcome joy and explore your sense of identity before integrating the entire experience. Throughout, the teacher's voice remains steady and neutral, creating space for whatever emerges without judgment or direction.

What You Might Experience

Most people feel deeply relaxed during iRest, though this isn't the primary goal. You might notice your body feeling heavy, warm, or tingling. Some experience a profound sense of stillness or spaciousness. Others report feeling 'held' or safely contained, which can be particularly meaningful for those with trauma histories.

Emotional responses vary considerably. You might feel peaceful and calm, or unexpected emotions could surface — sadness, anger, or even joy. This is normal and part of the process. The 'welcoming' approach means you're not trying to create any particular state, just noticing what's present.

Some people worry they're 'doing it wrong' if their mind stays active or they don't feel deeply relaxed. In iRest, there's no wrong way to practice. Mental activity, physical discomfort, or emotional intensity are all valid experiences to welcome rather than resist.

After the session, most people feel refreshed and grounded, though some initially feel slightly disoriented as they transition back to ordinary awareness. This settling period is normal and usually passes within a few minutes.

Aftercare and Integration

Take your time sitting up and moving around after the session. Many people feel like they've had deep, restorative sleep even if they were aware throughout. Drink water and eat something light if you feel spacey or ungrounded.

Avoid making important decisions immediately after practice, as you may feel unusually calm or introspective. This isn't problematic — just different from your usual mental state. Some people find journaling helpful to capture any insights or feelings that emerged during the session.

If difficult emotions or memories surfaced during practice, don't feel compelled to analyse or 'work through' them immediately. The iRest approach is to simply notice and welcome, allowing natural processing to occur over time. However, if you feel overwhelmed or distressed, contact your teacher or a mental health professional.

Some practitioners notice improved sleep quality the night following a session, while others feel more emotionally balanced over the following days. These benefits often become more pronounced with regular practice.

Building a Practice

Most iRest programmes run for 8-12 weeks with weekly sessions, mirroring the protocols used in military and veteran programmes. This timeframe allows the nervous system to gradually adapt to the practice and integrate its benefits. Some people notice changes after 3-4 sessions, while others require longer to feel significant shifts.

Between sessions, many teachers provide audio recordings for home practice. Even 10-15 minutes of iRest several times a week can reinforce what you're learning in guided sessions. The standardised protocol means recordings maintain the same structure and language, creating consistency that supports deeper practice.

After completing an initial course, some people continue with monthly maintenance sessions or join ongoing groups. Others develop a sustainable home practice using recorded sessions. The clinical research suggests that regular practice over several months provides the most robust benefits for conditions like PTSD, chronic pain, and sleep disturbances.

If you're working with iRest for specific symptoms or conditions, keep a simple log of your sleep quality, pain levels, or emotional wellbeing to track changes over time. This can help you and your healthcare providers understand how the practice is supporting your overall treatment plan.
