Chemicals in everyday plastics may disrupt the body’s natural 24-hour sleep-wake cycle and circadian rhythm in a way similar to coffee, which increases the risk of sleep disorders, diabetes, immune problems and cancer, new in vitro research shows.

The study looked at chemicals extracted from a PVC medical feeding tube and a polyurethane hydration pouch, like those used by long-distance runners. PVC and polyurethanes are also used in everything from kids toys to food packaging to furniture.

The findings showed for the first time how plastic chemicals probably wreak havoc on cell signals that regulate the body’s internal clock, throwing it off by up to 17 minutes.

“We don’t know the significance of it and you could say, ‘Oh it’s just 15 minutes so it’s not a big deal’, but it’s such a tightly controlled clock that it’s a significant shift,” he (Martin Wagner, a study co-author and plastic chemical researcher with the Norwegian Institute of Science and Technology) added.

Like the night guard my dentist urges me to wear? Sucking down that plastic all night long! Mmmmmm....delicious plastic....

Shit, i never thought about that!!!! I wear mine religiously since i have really bad tmj issues!

And the whole point of the night guard is to be ground up instead of my teeth. There are very clear ridges where my teeth have worn away huge chunks of the material

Well i hope that the material they use has been tested and approved safe for medical use

Otherwise my other option is to let my teeth grind down to the roots and my tm joint desintegrate

The way it was explained to me was that it needs to be a rigid material so that when i grind at night, my jaw keeps a certain angle that takes pressure off the TM joint.

So for me, the night guard has two functions. Relieve the joint, and prevent my enamel from wearing away

Maybe there's a market for artisinal wood carved night guards.
