When we’re asleep it’s a good idea to maintain a good posture; a mattress too soft will cause us to slouch, while one that’s too firm can apply pressure to our hips and shoulders.
Don’t forget about your pillow either. Neck pain, stiff necks and even persistent headaches could simply be the result of poor pillow support while in bed sleeping. A good pillow should hold your head in the correct alignment – that is, in the same relation to your shoulders and spine as if you were standing upright with the correct posture. One that is too soft will allow the head to flop, curving the neck. One that is too hard will give you a crick in the neck.
Additionally, pillows come filled with a choice of fillings – polyester, goosedown, duckdown, feather, fibre filled, and visco-elastic, latex or polyurethane foam, gel – and any number of combinations of these. It’s a good idea to invest in quality pillows and replace every two to three years.
