When it comes to Grooming, English differs from German in two respects. First, instead of using a simple verb like German duschen, English often uses a phrasal verb, where a meaningful noun (shower, bath) combines with a ‘light’ verb (take).
I take several showers a day. - Ich dusche mich mehrmals am Tag.
Second, while German expresses the Patient as though it is directly affected by the verb (as a direct or indirect object), English construes this participant more as a possessor of the body part (with a possessive pronoun).
I brush my teeth–Ich putze mir die Zähne.
I brush his teeth.–Ich putze ihm die Zähne.
