Look After Your Wellbeing This Winter with a Good Night’s Sleep: Our Top Tips

Sleep - it’s something we all need to function. We live in a time that places an emphasis on eating healthily and taking regular exercise, but none of that is made worthwhile without a good night’s sleep. According to the NHS, 1 in 3 of us suffer with poor sleep, and often, factors of a modern lifestyle are to blame - digital devices, stress, and bringing work home with us. While everyone is different, most adults need between 6 and 9 hours of sleep per night - in terms of finding out whether you’re getting enough sleep, the best indicator of this is whether or not you look for chances to nap during the day. If this is you, it may be that you’re not catching quite enough Zs. But with so many factors that can affect our ability to sleep well, how can we actually get a good night’s sleep? 


Why is Sleep So Important?


We’ve all experienced the short-term effects of a rubbish night’s sleep - feeling irritable, not being able to concentrate, that ‘heavy’ feeling on your eyes - but there’s actually a lot more to it, not just for your emotional and mental wellbeing, but also on your physical health too.



How Can We Get a Better Night’s Sleep?


So, we know the importance of a good night’s sleep on our overall health and wellbeing, but how exactly can we improve our chances of getting it? Given that there are so many factors that can affect the quality and the quantity of our sleep, there’s no surprise that there’s plenty of things we can do to improve it. One way in particular, is by reducing the amount of blue light you’re exposed to in the evenings.


What’s the Deal with Blue Light?


An internal function known as our circadian rhythm controls our sleeping and waking cycle. To adjust itself, our circadian rhythm relies on signals from the environment, specifically, light and darkness. Natural light or bright white lighting helps to regulate our circadian rhythms - both sunlight and white lights contain a significant amount of blue light, which helps us to stay alert. Blue light inhibits the production of a hormone called melatonin, also known as the sleep hormone. Secreted by the pineal gland in the brain, melatonin lets our bodies know that it’s time to relax and go to sleep, which is why a little blue light (especially from the sun) can be beneficial during the day. 


Of course, during the evenings, melatonin is what we need to help us fall asleep. Unfortunately, blue light is also emitted in high amounts from digital devices such as laptops and smartphones. So, if you spend your evenings scrolling through social media or curled up in bed watching Netflix on your laptop, this could indeed be impacting on your sleep. Blue light during the evenings has the opposite effect to what it does during the day, tricking your brain into thinking it’s daytime. 


How Can I Reduce My Exposure to Blue Light?


Thankfully, there are a number of ways in which you can reduce your blue light exposure to help you get a better night’s sleep. Blue light blocking glasses in particular are a popular way to reduce your blue light exposure, with one study even finding that when wearing them in a lit room or using electronic devices, people produced the same amount of melatonin as if it were dark. Blue light blocking glasses also have additional benefits when it comes to eye strain and relieving headaches too, helping your eyes to feel fresher after long days in front of a computer. We have a huge variety of stylish frames with high performance lenses to bring you comfortable vision all day long, so why not take a look at our selection of blue light blocking glasses?


Additionally, other ways you can help to reduce your blue light exposure can be to stop using digital devices (including the TV!) and turning off bright lights up to 2 hours before bedtime. If you really can’t bear to tear yourself away from your gadgets before bedtime, a pair of blue light blocking glasses could be just the thing for you!


Top Tips for a Good Night’s Sleep


While reducing your blue light exposure in the evenings is a great way for you to be on your way towards a good night’s sleep, there’s plenty of other tips you can try:


  • Ensure plenty of natural light during the day
  • Reduce your caffeine intake
  • Get up and go to sleep at the same time each day
  • Optimise your sleep environment - ensure you have a comfy mattress and pillows, and that your room is free from excessive noise or distractions.
  • Do something to relax before bed - activities such as yoga or meditation can be great ways to help you unwind before going to bed. 
  • Keep a notebook by your bed - if you’ve got a lot on your mind or there’s something bothering you, write it down to come back to in the morning. It doesn’t have to make sense or have any structure, just empty your thoughts out to help clear your mind!

We hope we’ve given you plenty of insight into how you can achieve a better night’s sleep. After a tough year all round, as we enter the winter months, this year it’s more important than ever to look after our wellbeing, and one of the best ways we can do so is by ensuring we treat ourselves to a good night’s sleep.
