If you or some one you love isn’t getting enough sleep, is struggling to get to sleep or you’re waking up feeling tired and worn out, this post is for you.
As stated in previous post on this blog: Sleep is super important.
So important that we really need to think of it as a pillar of health the same way we do diet, exercise and stress management.
What happens when we don’t get enough sleep?
One of the major areas impacted by sleep issues is our cardiovascular health.
Impacts of sleep on cardiovascular health include:
Increases chance of both developing and dying of CV disease by 45%
Heart attache - leading cause of death in Oz and stroke leading cause of disability.
Main mechanism - increases BP
Often people cn think of sleep as wasting time, but the reality is that your brain doesn’t work as well without it.
in an Australian study, no sleep for 19 hours was shown to have equivalent impact on concentration as being over .05 blood alcohol
As well, less than 5 hours sleep can lead to a 500% increase in risk of car accident
Once again, martin has come through with the goods with a video that will have you catching some of the best quality Z’s of your life in no time!
As always, the video is transcribed below. Please let us know if there is anything else we can do to get you back on track!
Intro: 0.00
Hi, Martin Harvey here from Align Chiropractic, and today’s video is all about sleep, why you need to get more of it, why it’s important for both your health, and also how easy it is to get the things you need to do done. So, timing this video, I’ve decided to do this video partly because I think sleep is super important, but also because this Saturday is when we go to daylight savings. Daylight savings is kind of like this mini experiment that we have each year where we all get like a tiny little bit of sleep deprivation and all feel mildly excited that it’s a step closer to summer. It’s interesting how many people are coming into the practice each year in this sort of period of time afterwards just not feeling as well as they normally will because they’ve missed out on one hour of sleep.
Impact of not enough sleep: 0.51
So, what I want to do is share with you a little bit of information about why health is super important, and then I want you share with you a couple if really simple things you can do to help yourself sleep better, and in the context of transitioning to daylight savings, what you can do to kind of get past that little hiccup as quickly as possible.
So, when we’re talking about sleep and impacts on health, there’s lots of things that it affects. It affects your risk of obesity, your risk of diabetes etc. One of the key things that I wanted to highlight was the impact of not enough sleep on cardiovascular health- your heart health, because the leading cause of death in Australia is cardiovascular issues, and also one of the leading causes of disability in Australia, Stroke, is also at an increased risk if you have sleep deprivation. So, interesting research in this area shows that you increase your risk of having cardiovascular disease by about 45% if you’re not getting enough sleep, and if you already have cardiovascular disease, increase the chance of dying from it by about 45% if you’re not getting enough sleep. So, it’s kind of important.
Now, how does it work? What’s the link between not enough sleep and this impact of cardiovascular health? It’s probably a bunch of mechanisms, but what the research suggests is a lot of it is because it increases your blood pressure. Even one night of not enough sleep can have a measurable impact in terms of increasing your blood pressure. So, it’s not a tiny thing- it’s a really important thing.
So, the information that I’m sharing with you is mainly from a really cool book by a neuroscientist called Matthew Walker. It’s kind of a world leader in the area of sleep and health. Another thing- and this is often one of the things that people notice, is that they just kind of feel a bit foggy and a bit out of it when they haven’t slept as much as they should, and the science in this area is really, really interesting. You see, if you haven’t slept enough, it impacts your concentration. That not only mean that it’s harder to get the work that you want done, it’s harder for you to be as present for your family and friends, it’s harder for you to do everything. It’ll measurably increase the chance of you having a car accident.
Experiment: 3:15
So, there was some research done in Australia where what they tried to quantify this. What they did was look at how well subjects in these studies did on a standardized concentration test, and the findings were really amazing where having the subjects be up for 19 hours- which isn’t a huge amount, like it’s not missing a complete night’s sleep, but just staying up a little bit later than you normally would. It meant that those subjects performed as badly on concentration tests as people who were over 0.05 blood alcohol level. So, not having enough sleep dulls down your brain to the level that you’re functioning almost as if you’re a little bit drunk.
Sleep better: 4:00
Now, what you can do to sleep better? If you’re one of those people who have trouble sleeping, or you just want to optimise your health and sleep better, there is a couple of really simple things to help yourself sleep better.
It feels bad to say this because I’m such a coffee fan, but avoiding caffeine late in the day is an obvious, but really important one. When Matthew Walker’s talking about this in his book, he talks about the half-life of caffeine. This means how long does it take for the amount of caffeine in your bloodstream to reduce by half- which is about 12 hours. So, what that means then is if you’re wanting to go to bed at 10 and you had a coffee at 10, you still have a significant portion of the caffeine in your blood. So making sure that if you are a coffee lover like I am, biasing that toward earlier in the day is going to help you sleep better later at night.
Interestingly, a lot of people will say that they sleep better if they have a glass or two of alcohol, but the science says there’s a pretty fine balance there. Yes, a glass or maybe two glasses can help people relax and be in a better state to sleep, but it often reduces your ability to go into the deeper levels of sleep which are the ones that we need to really rest, repair, and wake up rejuvenated. It also puts you into a shallower state of sleep. Often if we’re having more than a couple of drinks, there’s a mechanism which will often wake up once your liver has finished dealing with the alcohol- so, you’ll often find that after having had a few drinks that you’re then waking up at 3 in the morning finding it very, very difficult to sleep. So, minimising alcohol is a really important thing. So, looking forward to this Saturday when we lose an hour of sleep, it’s probably a good night to go easy in terms of how many drinks you have.
Exercise: 5:52
Exercise is a really powerful lever in terms of impacting our sleep. Exercising earlier in the day tends to create a biorhythm where we’re much more relaxed and drowsy for sleep later in the day. For a lot of people – particularly people who are in that night owl sort of group, exercising late in the day can often act as a stimulant, making it much harder to get to sleep.
Sleeping Strategies: 6:15
There are a couple of things that you can do in your environment to help you sleep better. One is having a hot bath later in the day because the heat and then the drop in temperature when you get out of the bath, that drop in temperature will make it easier, and sort of allow you to become dozy. We’re very strongly triggered by cool temperatures that will tend to stimulate an appropriate melatonin response, which is the sleep hormone
Related to that is having a cool room. They talk about wanting a room that’s under 20 degrees- ideally about 17/18 degrees Celsius, is sort of the sweet spot for most people to sleep better.
The last thing I want to share with you is the importance in terms of melatonin and getting sunlight into your eyes earlier in the day. So, getting outside and getting natural sunlight. Our melatonin production is stimulated by sunlight coming into our eyes, and then stimulating our pituitary to make melatonin. That production earlier in the day is what helps us feel sleepy later in the day. It sort of sets that biorhythm, but it’s strongly stimulated by light that’s coming in at that low angle that is present earlier in the day. So, getting outside without sunglasses early in the day, particularly going for a walk can be really powerful way of setting your biorhythm so you’re better able to sleep later on in the day.
Conclusion: 7:50
So, this is Martin Harvey from Align Chiropractic with a few tips to help you sleep better and get over the hump of the daylight savings.
