It's Sleep Week, so some people might be looking for ways to improve their shut-eye as it can have huge health benefits. One area of discussion which can divide opinion is around the number of pillows that you should use at night.
According to the experts, you only need one pillow beneath your head at night - but they add that it has to be the right pillow. The Sleep Foundation says that there are three sizes of pillow which range from one to five inches; low loft, medium loft and high loft.
The size that's right for you - as well as the firmness of your pillow - can depend on a multitude of factors, but the experts suggest that a good place to start is the way that you sleep. For example, side sleepers may be better off with a high-loft pillow while front sleepers should instead try a low loft option.
