Latest / Hardiness with Dr Paul Taylor / Wisdom Wednesdays: Is Your Job Protecting You From, Or Contributing to, Your Risk Of Dementia
Transcript
- 0:09Speaker 1: Hey, everybody, welcome to another edition of Wisdom Wednesdays. Today,
- 0:13Speaker 1: I want to talk about your job and is it
- 0:16Speaker 1: contributing to or reducing your risk of dementia. So I'm
- 0:20Speaker 1: going to pull a couple of different lines of research
- 0:24Speaker 1: into this, and the first was a study published in JAMA,
- 0:28Speaker 1: the Journal of the American Medical Association that looked at
- 0:32Speaker 1: about fifty thousand people in the uk Biobank study. So
- 0:37Speaker 1: if you've listened to this podcast, you know that this
- 0:39Speaker 1: is the Biobank. Uk Biobank Study is a gift that
- 0:42Speaker 1: keeps on giving. There are a huge amount of people
- 0:45Speaker 1: who are constantly pokest and broaded and asked about their lifestyle,
- 0:49Speaker 1: and then we follow them up and see who gets
- 0:51Speaker 1: chronic disease or dies early and see who doesn't, and
- 0:55Speaker 1: they're able to make some imprinces about these So this
- 0:59Speaker 1: study is showed. This was looking at the amount of
- 1:02Speaker 1: time that you spend sitting and your risk of dementia.
- 1:07Speaker 1: So those who sat for about ten hours a day
- 1:11Speaker 1: had an eight percent increased risk of dementia. For those
- 1:14Speaker 1: who sat for nine hours or less, those who sat
- 1:18Speaker 1: for twelve hours a day had a whopping sixty three
- 1:22Speaker 1: percent increased risk of dementia versus those who's had for
- 1:25Speaker 1: nine hours or less and those who's had for a
- 1:28Speaker 1: whopping fifteen hours, which there's a lot of sitting, they
- 1:31Speaker 1: had a two hundred and twenty one percent increased risk
- 1:34Speaker 1: of dementia versus those who sat for nine hours or less. Now,
- 1:38Speaker 1: a lot of people, whenever I talk about sitting, they
- 1:41Speaker 1: completely underestimate the amount of time that they sit. What
- 1:46Speaker 1: we know is that if you have an office job
- 1:48Speaker 1: or a pretty sedentary job, if you're in work for
- 1:51Speaker 1: eight hours, the typical individual will sit for six and
- 1:54Speaker 1: a half of that. Right now, Before that, you've got
- 1:57Speaker 1: to think about what you do in the morning when
- 1:58Speaker 1: you get up and whether you sit down for breakfast.
- 2:01Speaker 1: Then you got to think about your commute and how
- 2:04Speaker 1: long you spend sitting. And then the work doesn't include
- 2:09Speaker 1: the lunchtime, so you got to think about that time.
- 2:11Speaker 1: Then you got to think about if you commute home
- 2:13Speaker 1: as well. You add that sitting in. So we've got
- 2:17Speaker 1: those things plus the six and a half hours if
- 2:20Speaker 1: you're in a sedentary job, and then we come home
- 2:23Speaker 1: and we've had a hard day, so we relax, and
- 2:26Speaker 1: it is very easy to accumulate those twelve plus rs
- 2:31Speaker 1: a day. And what they also find that exercise doesn't
- 2:37Speaker 1: undo all of the effects. So, and I've talked about
- 2:40Speaker 1: this before, being sedentary is a completely independent risk factor
- 2:48Speaker 1: from sitting. So what I mean by that is that
- 2:51Speaker 1: you can sit a lot and exercise and you still
- 2:54Speaker 1: have one risk factor for chronic disease. But if you
- 2:56Speaker 1: sit a lot and you don't exercise, you don't have
- 2:59Speaker 1: two who different risk factors for chronic disease, and they
- 3:03Speaker 1: become additive to some extent. So it's thinking about all
- 3:08Speaker 1: of the stuff that you're doing. And we know that
- 3:11Speaker 1: breaking up the periods of prolonged sitting is really really key.
- 3:16Speaker 1: And I'm going to get to that at the end
- 3:18Speaker 1: because another bit of research I want to talk about
- 3:21Speaker 1: was showing that jobs were your reasonably active physically, they
- 3:26Speaker 1: actually reduced a risk of dementia. But a study in
- 3:30Speaker 1: the landsets showed that the most physically demanding jobs actually
- 3:35Speaker 1: increased the risk of dementia. And these guys had a
- 3:38Speaker 1: bar roughly fifty to sixty percent increased risk of dementia
- 3:42Speaker 1: for people who were moderately physically active in their jobs.
- 3:46Speaker 1: Now there was a bit of nuance under it, because
- 3:50Speaker 1: these jobs often had a lack of autonomy, They had
- 3:54Speaker 1: prolonged standing and the work was hard. There was rigid workers,
- 3:59Speaker 1: and there was a lot of stress and risk of
- 4:01Speaker 1: burnout and sometimes inconvenient working days. So it's not just
- 4:05Speaker 1: about being physically active. It's a physically active, stressful, rigid
- 4:10Speaker 1: job that seems to carry those extra risks. Now, another
- 4:15Speaker 1: line of research actually looks about the cognitive stimulation in
- 4:21Speaker 1: your job, and this was a study of seven thousand
- 4:24Speaker 1: Norwegians who had three hundred and five different occupations across them,
- 4:29Speaker 1: and what they found was that the jobs that were
- 4:32Speaker 1: the least mentally challenging, that had a lot of routine,
- 4:38Speaker 1: unchallenging work, actually were sixty six percent more likely to
- 4:44Speaker 1: have mild cognitive impowerment when they became older adults and
- 4:48Speaker 1: thirty one percent more likely to have dementia after the
- 4:52Speaker 1: years of seventy compared to those who had mentally sorry
- 4:57Speaker 1: taxing jobs. So there is a bit of a balance
- 5:01Speaker 1: to be played here. You don't want to be doing
- 5:03Speaker 1: a job that is boring as batshit and has lots
- 5:05Speaker 1: of routine, but you want to have a job that
- 5:09Speaker 1: is actually mentally taxing, but not really rigorously physically taxing
- 5:15Speaker 1: as well. So probably the best job is one that
- 5:19Speaker 1: is quite mentally taxing, where you have to think about stuff,
- 5:22Speaker 1: and you know that's pretty obvious how that is going
- 5:26Speaker 1: to keep your brain young and healthy. But ideally you
- 5:30Speaker 1: should be having the opportunity to move a reasonable amount.
- 5:34Speaker 1: And then the worst job is one that you're sitting
- 5:38Speaker 1: all day long doing very routine tasks, or you're doing
- 5:44Speaker 1: stuff that is really stressful and highly physically stressful and
- 5:48Speaker 1: a lack of autonomy and all of those things. So
- 5:51Speaker 1: ways things that we can do. We know that actually
- 5:56Speaker 1: breaking up our sitting is really really key. And I
- 5:59Speaker 1: mentioned this a little bit earlier on. I've actually just
- 6:01Speaker 1: taken delivery of a little Pomodoro clock, which is pretty
- 6:05Speaker 1: cool because I'm a massive fan of that technique. And
- 6:08Speaker 1: that's basically where you're in control of your diary. You
- 6:11Speaker 1: work in thirty minute chunks, and then you get up
- 6:15Speaker 1: and you move for five minutes and take a little break,
- 6:18Speaker 1: get up and move, do some breathing, drink some water.
- 6:22Speaker 1: That is like taking your brain out and plugging it
- 6:24Speaker 1: into a wall, but getting up every thirty minutes and moving,
- 6:29Speaker 1: either doing a little bit of vigorous activity, running up
- 6:31Speaker 1: and down a couple of flights of stirs, or walking
- 6:33Speaker 1: for a few minutes. That actual movement off sets a
- 6:38Speaker 1: lot of the changes in gene expression that are associated
- 6:42Speaker 1: with prolonged sitting, so that the worst thing that you
- 6:44Speaker 1: can do is sit for long periods of time. So
- 6:47Speaker 1: ideally use the Pomodoro technique, have those regular breaks, standing meetings,
- 6:52Speaker 1: walking meetings. They're great ideas. And another rule that I
- 6:57Speaker 1: have is never ever sit when you're on the phone,
- 7:00Speaker 1: So when the phone rings, you have to stand up
- 7:02Speaker 1: or walk around to answer that phone, because there is
- 7:06Speaker 1: huge value in just breaking up that sitting because the
- 7:10Speaker 1: inactivity physiology we know is pretty damn horrible. So that's
- 7:16Speaker 1: it for this week, folks, catch you next time.
