More 'ouch' than 'Zzz...'
The foetal position
Sleeping on your stomach
This position makes you twist your head and neck in an unnatural way so it again brings on tension.
Putting your arm over your head
This can cut off circulation and put pressure around your nerves which disrupts blood flow.
So what position is the ideal?
It’s called ‘the corpse.’ Yes, just imagine you’re lying in a coffin (cheery visual, we know) as lying on your back is the best position to sleep in as it keeps your spine straight and blood flowing. But, if you’re a snorer, this position might be tricky for you, so consider sleeping on your side as straight as you possibly can and don’t elevate your neck too much.
