Sleep plays a crucial role in maintaining overall health and well-being, and recent research has revealed a strong link between sleep and cardiovascular health. A study conducted by the University of Warwick in the UK found that individuals who get 7-9 hours of sleep per night have a lower risk of cardiovascular disease (CVD) and mortality compared to those who sleep less or more than the recommended range.
The study, published in the Journal of the American College of Cardiology, analysed data from over 116,000 participants in the UK Biobank study and found that those who slept less than 6 hours or more than 9 hours had a higher risk of CVD and mortality. These findings add to the growing body of evidence that suggests a link between sleep duration and cardiovascular health.
The exact mechanisms by which sleep affects cardiovascular health are not fully understood, but researchers suggest that it may be related to the impact of sleep on cardiovascular regulation, inflammation, and metabolic function.
It is important to prioritize sleep and aim for the recommended range of 7-9 hours to maintain cardiovascular health.
It’s worth noting that these findings are observational, and more research is needed to fully understand the relationship between sleep and cardiovascular health, but it’s a good indication that sleep plays a vital role in maintaining a healthy cardiovascular system.

A good night’s sleep is essential to your health, and an important part of your overall well-being. People spend about a third of their lives in bed, so it’s vitally important to get it right when it comes to back health. Back pain can significantly affect a person’s ability to get the quality and amount of sleep they need. Furthermore, poor bed posture can worsen or even be the cause of backache in the first place. This is because certain positions can place unnecessary pressure on the neck, hips, and back.
This blog will provide an in-depth review of different sleeping positions and types of beds and the impact both have on your quality of sleep.
Before looking at the positions to sleep better, it is important to address a few crucial things. First and foremost, you should be comfortable. For a good night’s sleep, waking up feeling properly rested and not in pain is the most important thing. If any of these positions cause issues, don’t hesitate in letting me (or another osteopath) know so that alternative suggestions can be made and you find something else that works for you.
Secondly, I know it’s not always possible to control what position you get into once you’ve fallen asleep. However, this is where perseverance comes in, if you keep trying, your body can adapt in a week or two. Pillows are always a good ally, to stop you rolling one way or the other.
Here are some positional tips that can help you get a better night’s sleep:
1. The Classic: Lying on your back.
Lying on the back is probably the best all-around sleeping position for a healthy back. It ensures good spinal alignment from the head and cervical vertebrae, through the thoracic and lumbar, all the way down to the pelvis. Because the back is the body’s largest area, weight is most widely distributed in this position, minimising pressure hot spots. This doesn’t suit everyone though, some people don’t feel as ‘nested’ as in other positions so, they struggle to get to sleep on their backs. Also, snorers may find that this position exacerbates the problem.
For people who like back sleeping, it’s definitely worth adding a pillow under your knees. It loosens the hamstrings a little and takes some pressure off the lumbar lordosis.
2. The Foetal Position: Lying on your side with your knees up a little.
This is a fairly intuitive position to get into if you have lumbar disc issues as it slightly flexes the low back and opens up the gaps in the facet joints.
Again, a good tip in this position is to use a pillow, however, this time put it in between your knees. This stops your top leg dropping forward and rotating the low back. It also aligns your hips and pelvis better, and feels more comfortable on the upper knee.
Try to swap sides from time to time if you’re lying in the foetal position.
3. Face Down: Lying on your stomach.
I normally ask people to avoid this position, it’s usually quite problematic for the neck as well as the low back. Unfortunately, for a lot of people, it’s the only position they can fall asleep in, or any other position makes them snore. If you’re one of them, reach for that extra pillow again and put it under your low stomach and upper pelvis to take the pressure off the low back. This is a good idea if you’re having a massage too. Front lying needs a much flatter pillow (or even no pillow) under the head too.
If you’re someone who falls asleep on their back or side, then rolls over in their sleep and wakes up on their stomach, try hugging a large pillow against your chest and stomach to keep you in position. Another reason sleeping on the front is considered bad is because the head is usually turned to one side. This twists the spine and places additional stress on the neck, shoulders, and back. To avoid this, you can try lying face down. Place a small firm pillow or tightly rolled-up towel under the forehead, or better still a face pillow, allowing room to breathe. In this position, you should still place a pillow under the stomach.
4. Reclined Sleeping.
If all else fails, you can try sleeping in a reclined position. People with spondylolisthesis, for instance, may resort to this after finding it comfortable falling asleep in a recliner chair. There are beds available that can be sat up slightly. So, this is worth investigating.
What about the perfect bed for sleep?
There are so many different opinions about beds that I don’t even know where to start, nonetheless here’s mine.
Spend some time and effort (and dare I say money) choosing a bed and mattress. People seem happy to spend thirty times or more on a car than a mattress, but remember, a third of your life is spent in bed!
It’s really difficult to choose a mattress on a twenty minute trip to the bed store, so really take your time, spend an afternoon there, take your shoes off, try different sleeping positions, not just lying on your back! Do your research before you go, but make sure the review sites you look at aren’t secretly run by a bed company, or affiliated to one.
Try not to be seduced by softness. Lots of people jot down the name of a mattress they’ve found comfortable in a hotel, and while this can sometimes be a good indicator, you should know that hotels buy mattresses to give you a couple of nights feeling like you were sleeping on a cloud, but these mattresses are usually not supportive enough to be using full time, especially if you have low back issues, which can be aggravated over weeks and months. Often the mattress in a big hotel chain is not available to buy for the public as they are specifically manufactured for different hotels’ standards.
A fairly firm mattress is usually a good idea, perhaps with a shallow in-built topper. This can give you the support you need for your low back while the topper takes the pressure off bony prominences and allows shoulders and hips of side sleepers to sink in a little. I suggested a built in topper as they are usually better segmented and don’t allow stuffing to move around and bunch up as much. However, removable toppers give you more scope to adapt by removing it if needed, and also allow you to flip the mattress.
Mattresses that are fully stuffed as well as sprung are good and supportive. Price is a good indicator for a quality mattress. £1,500 for a king size mattress is not excessive. While we’re talking about price, beware of anything that seems too good to be true. The “Winning awards” mattresses need to be checked as to which award, and who’s giving it!
Memory Foam Mattress
Patients have different opinions about memory foam mattresses. While some patients swear by them, others do not get along with them. I’d like to reiterate the price, if you’re set on a memory foam mattress, find the one with better quality, so it doesn’t start to develop a permanent dip where you lie. It’s all about density which is measured in pounds of pressure per cubic square foot. More is normally more expensive and better quality, but at the same time is also more supportive and feels harder.
There can be a problem with memory foam mattresses feeling too hot. While many of the better brands have addressed this to an extent, many memory foam mattresses have become hybrids so, it’s not just 100% foam any more.
Mattresses should be changed about every 8 years, but you can keep the same bed base, of course, as long as it’s not damaged. Divans have pretty thin wood tops that can crack or bow so, check it carefully.
In my opinion, a platform base is always the best. If the base is sprung, the whole mattress will start to fold which is usually not what they’re designed to do. A slatted base is slightly better than a fully sprung one, but still not as good as a solid base.
Finally, I should mention pillows. Pillows are very subjective to the person, and especially to any neck/upper back/shoulder girdle conditions they may have.
As a rule of thumb (and this is painting with a very broad brush) people seem to usually have too much pillow depth more often than too little. One medium depth pillow is usually best if you don’t have any specific issues. I find feather works well as you can punch and mould it to the right height and shape, so there is some support under your neck but that’s very much a personal preference.
I rarely see anyone who gets on well with memory foam pillows (there are the odd one or two) or sprung pillows.
The price of a good feather pillow is probably about £50, but as I said right at the start, I want you to not only be in a good position, but also comfortable and pain-free during the night and the next day, so if a £5 pillow works for you then that’s absolutely fine. Don’t forget most pillows can be laundered regularly which may give (especially feather pillows) some of their volume back.
If you are experiencing neck pain though, get your neck examined and treated first and ask your osteopath what pillow they would suggest for you specifically going forward.
BE ‘BED FIT’
The healthier and stronger your back is, the better night’s sleep you will get and the better your back will be when you get up in the morning.
Core strengthening exercises will help support the back during the night and prevent back spasms. Gentle stretching before bed can increase flexibility and help to relax the body and reduce stress.
Take care getting in, and especially out, of bed. Take your time. When you wake up in the morning, allow a few minutes to get your muscles and joints moving fully instead of leaping out of bed at the alarm. Roll onto your side then use your arms to push you upright while your legs drop over the side, then sit there for a minute moving gently before slowly standing up.
Perhaps most importantly, if you do have a back or musculoskeletal issue, get it checked. A health professional can assess why you’re suffering and help treat the symptoms. They can suggest the correct investigations, treatment and exercises, as well as further helping you to choose that all important correct mattress.
Booking an appointment with an osteopath could be the start of ending your back pain for good!
Sleep is one of our greatest allies when it comes to health and wellbeing. It is associated with a number of health benefits which can have a huge positive impact on our daily lives.
Conversely, a lack of sleep can be detrimental – research has even found that not getting enough sleep can negatively impact some aspects of brain function to a similar degree as alcohol intoxication!
Dr Belinda Griffiths discusses some of the mental and physical health benefits of getting a good night’s sleep.
During sleep, your body releases cytokines, which are essential for the regulation of the immune system. Cytokines are required in increased amounts when you are attacked by a pathogen (when you’re ill) or under stress. The level of cytokines increases during sleep, and therefore lack of sleep hinders the body’s ability to fight infections. This is also the reason why the body tends to sleep more while suffering from an infection.
When you’re well-rested, you’re less hungry. Being sleep deprived disrupts the hormones in your brain (Leptin and Ghrelin) that control appetite.
With those out of balance, your resistance to the temptation of unhealthy foods goes way down. And when you’re tired, you’re less likely to want to get up and move your body. Together, it’s a recipe for putting on the pounds!
If your sport requires quick bursts of energy, like wrestling or weightlifting, sleep loss may not affect you as much as endurance sports like running, swimming, and biking. But you’re not doing yourself any favours. Besides robbing you of your energy and time for muscle repair, lack of sleep saps your motivation, which is what gets you across the finish line. You’ll face a harder mental and physical challenge – and see slower reaction times. Proper rest sets you up for your best performance.
When you’re tired, you can have difficulty recalling information. That’s because sleep plays a big part in both learning and memory. Without sufficient sleep, the brain finds it difficult to focus and take in new information in the first place and then doesn’t have enough time to properly store information as short-term memories. Sleep helps enable you to retain memories and store information.
Sleep also allows for your mind to rest, repair and rebuild, the same way it does for your body. As you sleep, your brain begins to organise and process all the information you’ve taken in during the day. It converts these short-term memories into long-term memories – this helps you to learn.
Not sleeping properly can mean that both your body and brain don’t function properly the next day. It can impair your attention span, concentration, strategic thinking, risk assessment, reaction times and problem-solving skills. This is particularly important if you have a big decision to make, are driving, or are operating heavy machinery. So, getting plenty of sleep can help you stay sharp and focused all day long.
Another thing your brain does while you sleep is process your emotions. Your mind needs this time in order to recognise and react in the right way. When you cut that short, you tend to have more negative emotional reactions and fewer positive ones. Lack of sleep can cause bad temper and anxiety, so the better you sleep, the better your ability to stay calm, controlled and reasonable.
Chronic lack of sleep can also raise your chance of having a mood disorder. One large study found that people with insomnia were five times more likely to develop depression, and the odds of having anxiety or panic disorders are even greater.
A refreshing slumber helps you hit the reset button on a bad day, improve your outlook on life, and be better prepared to meet the challenges of the next day.
While you sleep, your blood pressure goes down giving your heart and blood vessels a bit of a rest. The less sleep you get, the longer your blood pressure stays up during a 24-hour cycle. High blood pressure can lead to heart disease and strokes. Therefore, it is important to keep your blood pressure down.
Poor sleep and pain mutually reinforce each other. Sleep deprivation increases pain sensitivity and reduces pain tolerance. Therefore, something will feel more painful when you’re tired.
It is clear that sleep is an essential part of helping us stay physically and mentally healthy. What better excuse to have a few extra hours of sleep a day!

Do you often find yourself trawling through Instagram just before going to bed? Waking up and checking your emails before you even have a shower or a coffee? Former Facebook chief marketing officer Randi Zuckerberg hit the nail on the head when she said that people need to understand that while “the phone is an amazing tool, we own our devices, they don’t own us.” It’s time for your digital detox.
The average smartphone user checks their phone 221 times a day. The Oxford English Dictionary defines a digital detox as “a period of time during which a person refrains from using electronic devices such as smartphones or computers, regarded as an opportunity to reduce stress or focus on social interaction in the physical world.”
By periodically unplugging, you can start reclaiming real life experiences rather than living in a virtual world. So how can we get this started?
Appreciate the silence – We have become so accustomed to filling every spare moment with digital noise. Try hitting reset on your brain from time to time and take a few moments to just let your mind wander. Be comfortable with silence, slow down and be present in the moment without the glow of a screen.
Kick technology out of the bedroom – Give yourself a technology curfew and when you say “lights out” actually mean it. Harvard researchers have found that technological devices such as phones, tablets and laptops can disrupt melatonin production, sleep quality and mood. To avoid temptation, banish your devices from the bedroom and try using an old fashioned alarm clock!
Socialise in the real world – Let’s face it, how many of the people you follow on your social media are actually your close friends? At 1am when you are struggling to sleep, do you really need to look at pictures of what they ate for lunch? Whilst social media can have its uses and be a positive influence, it can have a negative effect on our wellbeing as a result of comparing our lives to those carefully edited for show.
Hit the pause button – Be conscious of how often you check your phone – next time you go to reach for technology, hit the metaphorical pause button. Take a breath and think about what you are going to get out of it. Is there a more meaningful and productive way to spend your time, such as going for a walk and getting some fresh air and movement instead?
We get 525,600 precious minutes a year, how you choose to spend them is up to you.
