WHAT’S NEXT: BCALM Instant relief from panic attacks


A whole host of treatments are available for anxiety, from cognitive behavioural therapy to mindfulness. But when it comes to panic attacks, the makers of the bcalm inhaler say that many epiosdes are triggered not by psychological issues but by a physiological one: a sensitivity to high levels of carbon dioxide (CO2).

What it does

The researchers behind bcalm noticed that people prone to panic attacks often have a low tolerance to high levels of CO2, for example in a lift or a stuffy room. To avert an attack, you exhale into the discreet bcalm inhaler, then inhale air that has been filtered by the device. The makers compare it to breathing in ‘forest air’. After half a dozen breaths you feel calm again. For hygiene reasons, you can only use the device once.

How it works

In people with sensitivity to CO2, receptors in the throat send a message to the brain which sets off a panic attack. The bcalm inhaler, which is regulated by MHRA (The Medicines and Healthcare products Regulatory Agency), contains a carbon dioxide absorbent. As CO2 is removed from the air you are breathing in, the receptor in your airway stops sending messages to your brain that you need to flee, and the sense of panic goes away.
