You'll find that all sorts of things can affect the quality of your sleep. The type of bed you have, what condition your mattress is in, how noisy your bedroom is and what you do immediately before going to sleep can all impact on how deeply you sleep and how refreshed you feel when you wake up. A key factor in how well you sleep is choosing your bedding wisely - too hot and you'll be tossing and turning all night, too chilly and you could wake up shivering in the small hours, so pick your duvet carefully. Lower tog values are more appropriate for the summer months while higher tog values will keep you cosy through the cold winter months, but there's no one-size-fits-all approach and everyone likes to sleep at a different temperature, so experiment with what works best for you. Many retailers offer a set of two duvets of different tog values which can be fastened together. For example, a 4.5 tog and a 9 tog quilt are great for warmer weather; fasten both together for a cosy 13.5 tog duvet that will keep you toasty when the weather outside is frightful. The fabric that your duvet cover, bottom sheets and pillow cases are made of could also affect your sleep quality; coarse weaves or those made of 100% cotton might feel like they're drying your skin out, while some people find satin and polycotton blends too warm and sticky to sleep in. The higher the thread count of your bedding, the more luxurious or finely woven it is, so using sheets with a high thread-count could help you improve your sleep - like duvets, personal preference is key, so try a few options to see what floats your boat. Of course, there's no point in meticulously choosing the most comfortable bedding if you've got a mattress that's old and worn out.
