Measuring is knowing, right?<\/p><\/h1><\/div>

<\/span><\/div>

I've been wearing a WHOOP band on my wrist for three weeks now, because measuring is knowing. Right?<\/p>\n

It's been a while since I sent a newsletter, but today I want to share something I was curious about myself: data about my health.<\/p>\n

Over the past few weeks I was approached several times by 'coaches' who wanted me to sell a supplement, often linked to a dried blood spot test.<\/p>\n

You guessed it: almost everyone's Omega 3 level turned out to be too low. Measuring is knowing, I heard them say. And luckily they had the perfect supplement to \u201ccorrect\u201d it\u2026<\/p>\n

Would I then also like to bring in other people so I would get a discount and commission? No thanks. That's not what I stand for.<\/p>\n

My search: measuring without radiation (and without the madness)<\/h2>\n

When I exercise I use a Garmin, purely for distance, heart rate and time. I rarely wear it during the day, and never at night. But my curiosity won: I wanted to go a step further, but without a watch and without constant Bluetooth.<\/p>\n

I looked into two smart rings: the Oura Ring and the Ultrahuman Ring. Both around \u20ac300. Oura also requires a subscription, and Ultrahuman always has Bluetooth active, a no-go for me, especially at night.<\/p>\n

So… no ring. Then I came across the WHOOP band. The first month is almost free (shipping costs only), and you can send it back if you cancel. So for less than \u20ac25, a month of insight. I decided to give it a try.<\/p>\n

My honest opinion<\/h2>\n

The WHOOP is a band without a screen that you wear day and night. Fewer distractions, they say. But as soon as you connect the app, it starts: notifications when you close the app, when you take it off for a moment, or when you sleep without a connection. It feels as if you have to keep measuring, otherwise it no longer \u201cadds up\u201d.<\/p>\n

You don't even have to take it off to charge it, you just slide a battery over the band. Handy, you would think. But sometimes you just don't want to wear the band. No measuring for a while. A bit of peace. But then you get notifications again or you miss data. That made me feel trapped.<\/p>\n

At night you constantly have a red or green light directly on your skin, on your vein. For your biological clock and melatonin production that is far from ideal. And it actually woke me up when I lay on it. Just\u2026 not nice.<\/p>\n

My sleep score was between 98\u2013100% every night, while I clearly felt a difference myself. So I couldn't get much out of that. My heart rate? Fine. But that doesn't surprise me. What did seem interesting: the HRV measurement.<\/p>\n

HRV and Bluetooth<\/h2>\n

HRV (heart rate variability) is the variation in time between heartbeats and says something about your recovery, resilience and nervous system. The higher, the better. But mine was unexpectedly low…<\/p>\n

I looked into it: WHOOP only measures HRV during deep sleep, and only when Bluetooth is active. But I switch everything wireless off at night. So that HRV measurement? Probably incomplete or not measured at all.<\/p>\n

WHOOP in a nutshell<\/h2>\n

Pros:<\/h3>\n
    \n
  • User-friendly app with clear data<\/li>\n
  • Charging without taking it off (for those who find that handy)<\/li>\n
  • Cheap to try for the first month<\/li>\n
  • No screen = fewer distractions during the day<\/li>\n<\/ul>\n

    Cons:<\/h3>\n
      \n
    • Uncomfortable to wear while sleeping<\/li>\n
    • Constant notifications and pressure to \u201ctrack\u201d<\/li>\n
    • HRV is inaccurate without Bluetooth (which I switch off at night)<\/li>\n
    • The light on your skin disturbs your biological clock<\/li>\n
    • A sense of losing control rather than being in charge<\/li>\n<\/ul>\n

      Measuring is knowing\u2026 but feeling is wisdom<\/h2>\n

      Measuring is useful. But for me, feeling remains the most powerful. The catch: feeling can also mislead you. After a few beers you feel good too, right?<\/p>\n

      So feeling with knowledge?<\/p>\n

      Living by the wisdom of age-old principles, such as sunlight, water, cold and natural rhythms, gives you a deeper sense of balance. And when you stray from it, you notice straight away. That is feeling on the right side of the spectrum.<\/p>\n

      We are excited to keep sharing that with you. So what are you waiting for?<\/p>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":27185,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_mv_en_title":"Measuring is knowing\u2026 right? | MIVIDA.life","_mv_en_desc":"","footnotes":""},"categories":[235,243,236,413,240],"tags":[256,411,412,414],"class_list":["post-46845","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-gezondheid","category-health-wellbeing","category-lifestyle","category-nieuwsbrief","category-weetjes","tag-gezondheid","tag-meten","tag-nieuwsbrief","tag-whoop"],"_links":{"self":[{"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/posts\/46845","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/comments?post=46845"}],"version-history":[{"count":2,"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/posts\/46845\/revisions"}],"predecessor-version":[{"id":50919,"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/posts\/46845\/revisions\/50919"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/media\/27185"}],"wp:attachment":[{"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/media?parent=46845"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/categories?post=46845"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mivida.life\/en\/wp-json\/wp\/v2\/tags?post=46845"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
