Ida cools and calms. Pingala heats and activates. At any moment, one dominates — and it shapes what you should be doing.
In the yogic system, the breath rarely flows equally through both nostrils. One side is almost always more open — and which side reveals which nadi, which energy channel, is currently dominant. This shifts naturally through the day, roughly every 90 minutes.
Then answer 5 quick questions. We will combine your breath observation with your current state to tell you which channel is running — and what to do with that information right now.
The Hatha Yoga tradition identifies three primary nadis (energy channels) in the subtle body: Ida, Pingala, and Sushumna. At any given moment, one of the two lateral nadis — Ida (left, lunar) or Pingala (right, solar) — is dominant, and this dominance determines the quality of energy available for different activities. This check uses five questions derived from the classical signals described in the Hatha Yoga Pradīpikā and the Swara Yoga tradition to identify your current nadi state and its practical implications.
Swara Yoga is the Tantric science of nasal breath and its relationship to energy, time, and action. The Shiva Swarodaya — a classical text on this subject — details how the dominance of Ida or Pingala at specific times of day and lunar phases determines the auspiciousness of different activities. According to this tradition, right nostril (Pingala) dominance is favourable for eating, physical exercise, travel, and worldly activities. Left nostril (Ida) dominance is favourable for meditation, creative work, study, sleep, and any inward-directed activity. When both nostrils flow equally, Sushumna is briefly active — considered the ideal state for meditation and the rarest to catch.
The primary practice for balancing both nadis is Nadi Shodhana (alternate nostril breathing) — described in the Pranayama Guide on this site. This practice systematically purifies both channels and progressively opens Sushumna. Beyond pranayama, the tradition also identifies physical postures: lying on the side opposite to the nostril you want to open forces a shift in dominance within minutes. If Pingala is dominant and you want to shift to Ida, lie on your right side briefly.

The two primary nadis — Ida and Pingala — are the left and right energy channels flanking the central sushumna. Their dominance alternates in natural rhythms throughout the day, determining your current energetic state and what activities, practices, and decisions are most aligned with that state.
The left channel — associated with the moon, the right brain hemisphere, cooling energy, inward attention, and receptivity. Ida dominance is associated with heightened intuition, emotional sensitivity, and suitability for reflective, creative, and meditative activities.
The right channel — associated with the sun, the left brain hemisphere, heating energy, and outward attention. Pingala dominance is associated with analytical thinking, physical energy, and suitability for action, exercise, eating, and social engagement.
In a healthy system, Ida and Pingala dominance alternate approximately every 90 minutes — corresponding to the ultradian rhythm observed in Western chronobiology. When one nadi dominates for extended periods, imbalance results.
When Ida and Pingala are in balance, the sushumna nadi opens. Nadi Shodhana (alternate nostril breathing) is specifically designed to balance the two channels and create the conditions for sushumna opening and meditation.
