Prostrations are part of every Orthodox tradition, to my knowledge. You will even see people making prostrations publicly in church especially during Great Lent, but you will generally not see people doing it at a Sunday liturgy since (in most traditions) prostrations are forbidden on Sundays.

There are variances in the traditions also here. In Russian tradition all the people in the Church do prostration during the eucharist prayers where wine and old are turned into Communion, and also before they partake the Communion. But in Greek tradition they don't do any prostrations during the liturgy. Prostrations aren't forbidden on Sundays but if you partake Eucharist you are not allowed to do prostration during that day.

there is something about prostrations that’s interesting but i can’t tell what exactly scientifically. But it brings me relief everytime I do it in namaz. I understand that the act of submission is relieving (things will be ok/there is someone looking out for me) but also physically (hard to explain)

no wonder it’s the meat of the entire prayer. Taking a prayer break from my messy code problems really resets my brain strain very quickly.

They're part of the Western (Catholic) tradition as well, but less frequently encountered: during the Litany of the Saints that precedes ordination to the priesthood those to be ordained are prostrate; the ministers at the start of the Good Friday liturgy lie prostrate before the altar; and a few other special contexts.
