Um, there's also um muscular myofacial therapy. So like you can use the muscularkeeletal system and essentially exercise these muscles so that they just carry more muscle tone. That can work. I mean there's there's very famous work done with like people who play the digery do where they have to do the cyclical breathing. It ends up strengthening certain muscles that even when you're asleep they're a little stronger and they can maintain a little more tone. So sometimes that can help especially for more mild apnea cases.
