It can be difficult to catch your breath in fast-paced societies, awash with unhealthy food and ridden by pollution.

So it's no wonder an increasing number of people are attending conscious breathing workshops, where you repetitively inhale and exhale deeply for up to 90 minutes to help address anxiety, addiction, stress and a whole host of health problems.

Across the UK, there are a growing number of workshops and events in studios, corporate offices, the natural history museum and even parliament, where MPs and peers have been learning breathing techniques during yoga classes.

The NHS also promotes breathing exercises to reduce stress, and wellness influencers such as Wim Hof, Russell Brand and Fearne Cotton have lauded the rewards of the practice.
