Why does deep breathing make me dizzy?

Why does deep breathing make me dizzy?

Because big breaths shift more air than your body needs. Each breath out carries carbon dioxide away. Normally you make it and breathe it out at the same rate. Take lots of large breaths, and you breathe it out faster than you make it, so the level in your blood falls. That’s over-breathing, or hyperventilating.

Lower carbon dioxide tells the blood vessels in your brain to narrow a little. In a study of 33 healthy volunteers, how light-headed people felt while over-breathing closely followed the slowing of blood flow through a main artery in the brain (Bresseleers et al. 2010).

It can happen even with slow breathing, if each breath is very large. In a lab study, breathing at 6 breaths a minute, a pace many guides recommend, still led to mild over-breathing (Marchant et al. 2025). Slow isn’t enough on its own. Soft matters too. That’s the idea behind how to breathe properly: lower, slower, softer.

What should I do if I feel light-headed?

This is 4-6 breathing: in through your nose for 4 seconds, out for 6. Keep each breath small, as if someone next to you shouldn’t hear it. If you still feel light-headed, shrink the breaths further before you slow them down.

Why do my hands tingle during breathing exercises?

For the same reason. When carbon dioxide drops, the nerves in your hands, lips and face become more excitable, and you feel pins and needles (Macefield and Burke 1991). It’s very common: in a lab study, 13 of 15 healthy people felt tingling during 5 minutes of deliberate fast breathing (Montagna et al. 1995).

Some intense breathwork styles cause it on purpose, with fast breathing for minutes at a time. Calming breaths shouldn’t. If your fingers tingle during a slow breathing exercise, it’s a sign to breathe more softly. Types of breathwork explains the difference.

Why do breathing exercises make my anxiety worse?

A few reasons, and none of them mean you’re doing it wrong. Paying close attention to your breath can make you notice sensations you usually ignore. A long hold can feel like you’re running out of air. And big breaths can bring on dizziness that feels like the start of panic.

There’s a learning part too. In the same study of 33 volunteers, after a few rounds of over-breathing, a smell that had been paired with it made people feel light-headed again, with no drop in carbon dioxide and no change in blood flow (Bresseleers et al. 2010). Your body can learn to expect the feeling.

What helps: keep your eyes open, drop the holds, make the out-breath the longer half and keep the breaths small. If breathing feels out of control, how to stop hyperventilating is the page for that moment, and breathing exercises for anxiety has gentler ways in.

Why can’t I do box breathing?

Usually it’s the holds or the count. Both can be changed.

Triangle breathing hasn’t been studied as its own technique, but it sits in the slow range that research links to calmer physiology. For box breathing itself, the full guide has fixes for each side: box breathing.

Why do I cry during breathwork?

It happens to a lot of people, especially in longer or more intense sessions. Slowing down and paying attention to your body can bring up feelings you’ve been too busy to notice. There’s little research on why, so be wary of anyone who claims to know exactly what’s being released. If tears come, let them. Breathe normally for a while, and carry on only if you want to. When the tears belong to a loss, breathing exercises for grief are gentler company.

Is it normal to yawn during breathing exercises?

Yes, very. Yawns and sighs often turn up as you relax, or when your everyday breaths have been small and your body wants a bigger one. They’re harmless. Let the yawn happen, then go back to the count: with Breathform, just join in at the next tone.

• Bresseleers et al., 2010: In 33 healthy volunteers, light-headedness during hypocapnic over-breathing closely tracked changes in cerebral blood flow velocity; after a few episodes, light-headedness could be triggered by a cue alone, without changes in CO2 or blood flow.
• Marchant et al., 2025: In 84 students, six breaths a minute raised heart-rhythm signs of calm modestly more than box or 4-7-8 breathing; none changed mood.
• Macefield and Burke, 1991: Tingling (paraesthesiae) in the hands and face during voluntary hyperventilation comes from increased excitability of peripheral nerve fibres as carbon dioxide falls.
• Montagna et al., 1995: During 5 minutes of voluntary hyperventilation, 87% of 15 healthy volunteers developed paraesthesiae (tingling), related to changes in blood pH, CO2 and O2.

Questions people ask

Is it dangerous to feel dizzy during breathing exercises?

On dry land, sitting or lying down, it passes within a minute or two once you breathe normally, and it isn’t harmful. The risk is falling or fainting where that matters, which is why intense breathing and breath holds belong on the floor or in a chair. Never practise breath holds in or near water, and never while driving. If dizziness happens without any breathing exercise, mention it to your doctor.

Should I stop if my fingers tingle?

Pause, yes. Tingling is a sign you’ve been breathing more than you need. Breathe normally through your nose for a minute and it fades. Then carry on more gently, with smaller, quieter breaths and a longer out-breath. Some intense breathwork styles produce tingling on purpose, but for calming breaths it simply means slow down and soften.

Why do I feel out of breath after a breathing exercise?

Usually because the count was too slow or the holds too long for you today, and your body wants to catch up. A few ordinary breaths sort it out. Next time, shorten the count or drop the holds: 4 in and 6 out is plenty. If you often feel you can’t get a satisfying breath, even without exercises, air hunger explains why.
