Body parts “fall asleep” in English. What about in other languages?

The German phrases (Ameisenlaufen, pelzige Haut) seem odd. As a native German I've never heard of them and there's a grammatical error in the second one (it's cited as "pelziges Haut", the grammatical gender of the adjective and noun don't match up: Haut is feminine but pelziges indicates neuter). He doesn't seem to be a native speaker so I'd take that claim with a grain of salt.

The pins and needles part is closest to what it't called in Serbo-Croatian, guess it's the modernized version of what is found in nature. In SH(BS/HR/SR) you'd say "trne mi ruka" which would translate to "my hand is thorning" as in using thorn as a verb.

Is this true? I have never heard of any limb falling asleep. They may sleep, but the falling into sounds strange to my ears.

My native Danish is possibly fooling my perception. My leg can sleep ('sove'), but no way it could falde i søvn (the exact same construct as fall asleep).

The sleep part refers to the sensation of numbness. The tingling wake-up part seems to be associated with ants in large parts of the world. But not here. That would simply be tingling or prickling or some such thing.

I didn't know "fall sleep" worked in English too. The phrase used in Persian [0] would translate to the same thing.

[0] خواب رفتن, transliteration: "khab raftan"

As a native Portuguese speaker from Brazil (Sao Paulo), the use of “formigamento” sounds too formal to me.

I have always used “dormiu”, which translates to “fell asleep” (past tense). However, using it in the present (either simple or continuous) would sound odd to my ears.

That being said, Brazil has over 200 million speakers distributed across 3.2 million square miles, and the city of São Paulo accounts for only 5% of our total population (roughly).

In Sinhalese (https://en.wikipedia.org/wiki/Sinhalese_language), there is a specific word for numbness and local anesthesia: "හිරිවැටීම". Literally translated as "falling into numbness".

I am typing in Roman but for Urdu we have a word for it suun but also use sleep like in english

The formal medical term is related to the "running ants" expression: https://en.wikipedia.org/wiki/Formication

In Chinese they go “ma2” (麻）which means “numb” or “tingly”. Interestingly the character is also used for their spicy hot pot (麻辣火鍋) which uses a spice called Sichuan peppercorn (花椒) which makes your mouth go numb like novocaine.

In Greek it's "μούδιασε" (moó-thee-a-se) which is a completely standalone word, having the meaning of falling asleep, but not literally meaning that.

In Russian they don't fall asleep by themselves, it is you who make them so. 'Я отлежал руку' - I made my arm fall asleep by lying on it.

In Urdu they sleep as well. "Mera paoun so gaya hai". "My foot is sleeping" i.e. my foot has that intense tingling feeling.

In Japanese, they go numb (痺れる). The kanji 痺 means numb, palsy, or paralyzed.

Polish has ants or stiff hand or pins and needles sort of (ciarki).

that's interesting I talked to a New Zealander once and he didn't know what I mean until he finally said: "oh you mean pins and needles"

exactly the same expression in Hindi as well.
