Do you know what it is? … … If you guessed breath holding, you got it right! Breath holding (intermittent hypoxia training) holds tremendous benefits! Science is slowly catching up to the untapped potential of breath holding. Freedivers, like Stig, have been invaluable guinea pigs in demonstrating that the human body is far more capable than imagined, and the results of longer & long term holds. This opened the doorway to interest in studying the benefits of hypoxia & hypercapnia tolerance (resistance to low oxygen and high carbon dioxide levels). The first results have been promising, with studies in mice showing a protective potential in old age, one of the key indicators of a long and healthy life (see first comment for link to study). So… The question is… How long can you hold your breath?

Should you do breath holding when you are sick? Yes. And. No. Forget about going for a max breath hold. And you probably want to skip the weekly challenge. But 10, 20 or even 30 seconds of gentle breath holding? It helps. And it even was a staple when all of us were "sick" a few years ago. Check Stig's video (and the subsequent post why small breath holds do wonders)

How early should we start with breath holding focusing with children? Is it right from the start, or is it better to wait? Tune in to find out Stig's take about what is the best time to get started. And then, if you have kids (or cousins, pupils or student), why not do breath holding together this week. Check the classroom to get started…
