Bhastrika — Sanskrit for "bellows" — is the most stimulating practice in this catalog. The pattern is rapid, forceful inhalation and exhalation through the nose, performed in short rounds. It is named for a blacksmith's bellows for a reason: the breath is meant to be vigorous, and the felt effect is a marked increase in alertness.
This is the one practice in the eight where caution actually matters. Not because Bhastrika is dangerous — for healthy adults it is generally safe — but because the felt effects (light-headedness, tingling, warmth, a stimulating "buzz") are real, and they are amplified for anyone with cardiovascular conditions or certain other health states. We want to be straightforward about who should sit this one out.
Who should not do Bhastrika
- Anyone in pregnancy.
- Anyone with uncontrolled high blood pressure or a history of stroke.
- Anyone with active cardiovascular disease, heart conditions, or recent cardiac events.
- Anyone with epilepsy or a seizure disorder.
- Anyone with hernia, recent abdominal surgery, or active reflux flares.
- Anyone with severe acute respiratory illness.
- Anyone with panic disorder for whom hyperventilation has been a trigger.
Nerva's onboarding asks about these conditions and quietly removes Bhastrika and Kapalabhati from your library if you indicate any. You can re-enable them in Settings, but the default is to keep them away from you.
How to do it
- Sit comfortably with a straight spine. Lying down is not recommended for this practice.
- Take a few normal breaths first. Settle.
- Begin a rapid, forceful inhale-exhale through the nose at roughly one breath per second. Both halves are equally active. The belly moves prominently.
- Continue for ten to fifteen breaths.
- Stop, return to normal breathing, and sit quietly for thirty to sixty seconds. Notice the felt sense.
- That is one round. Most beginners do two to three rounds total.
What to expect, honestly
You will likely feel light-headed during your first few rounds. Some warmth in the chest is common. Tingling in the fingers and lips is common. These sensations subside within a minute of returning to normal breathing.
If you feel sharp pain, chest tightness, a fluttering heart sensation, or pronounced dizziness — stop immediately, sit quietly until normal sensation returns, and consider whether this is the right practice for you. If symptoms persist, consult a clinician.
The intended effect is alertness — a clearer-headed, more wakeful state — not a high. Done in moderation, the lift is small and useful. Done excessively, it tips into hyperventilation, which is not the goal.
When to use it
- Mid-morning energy slump. A short round is a workable alternative to a second coffee.
- Before focused mental work. If you find yourself foggy and need to come up rather than down.
- Not in the evening. Bhastrika is stimulating. Late-day practice can interfere with sleep.
- Not as a daily habit. Two to three times a week is plenty. This is a tool, not a routine.
Common mistakes
Doing it too long. Ten to fifteen breaths per round is the starting dose. Longer rounds amplify the side effects faster than the benefit.
Stacking rounds without breaks. The rest between rounds is part of the practice. Skip it and you are simply hyperventilating.
Forcing through dizziness. If you feel light-headed enough that the room shifts — stop. The practice should produce mild alertness, not impairment.
Doing it lying down. Always seated. Lying down increases the likelihood of feeling faint.
Frequently asked
How often should I do Bhastrika?
Two to three times a week is plenty. It is a stimulating tool, not a daily routine.
Will it raise my heart rate?
Yes, modestly, during the active rounds. This is part of the felt effect. If you have any cardiovascular condition, skip the practice.
Why is lying down discouraged?
Lying down increases the chance of feeling faint during the rapid breathing phase. Seated is safer and more sustainable.
Is tingling normal?
Mild tingling in the fingers or lips is common during the first few rounds and subsides quickly. Pronounced tingling, dizziness, or chest pressure is a signal to stop.
Can I do Bhastrika before sleep?
No. It is stimulating. Practice in the morning or early afternoon.
How does it compare to Kapalabhati?
Both are rapid breath practices. Bhastrika has equally active inhale and exhale. Kapalabhati has a sharp active exhale with a passive inhale. They share contraindications.
Not a medical device. Not medical advice. Consult a qualified clinician before using breathwork if you have a health condition.
