On Your Back
This is by far the best position for most people to sleep in. It allows your head, neck and spine to be kept in a more natural position, reducing any potential joint pains for muscle aches. It can also decrease acid reflux and helps maintain perkier breasts as their weight is fully supported. Wrinkles aren’t a worry with this position as your face is not squashed into your pillow all night, though as anyone who has ever slept next to a snorer will probably already know, this is definitely the most likely to cause loud snoring and heavy breathing!
