Using definite articles with body parts and clothing
In English, we use possessive adjectives like "my", "your", or "his" when talking about our bodies and clothes. We say "I wash my hands" or "he puts on his shoes". In Portuguese, doing this often sounds unnatural.
When it is already clear whose body or clothing is involved, Portuguese prefers the definite article. This means you will use words like o, a, os, and as instead of possessives. You literally say "I wash the hands" using verbs like lavar (to wash) or pentear (to comb).

Daily routines and grooming
When you do something to your own body, the person performing the action is clearly the owner. Because the context is obvious, you only need the definite article. This happens constantly with daily grooming habits.
Expressions like escovar os dentes (to brush one's teeth) or fazer a barba (to shave) are great examples. You are literally brushing "the" teeth and doing "the" beard.
Ela lavou as mãos antes do jantar.
(She washed her hands before dinner.)
Eu escovo os dentes de manhã e à noite.
(I brush my teeth in the morning and at night.)
O meu pai faz a barba todos os dias.
(My dad shaves every day.)
Ele penteia o cabelo no quarto.
(He combs his hair in the bedroom.)
Movements and gestures
Verbs used for moving your body parts follow the exact same pattern. Whether you are using fechar (to close), abrir (to open), or levantar (to raise), the definite article is the most natural choice.
This is also true for common expressions involving gestures, such as encolher os ombros (to shrug) or cruzar (to cross) your arms.
Por favor, feche os olhos.
(Please, close your eyes.)
Se sabes a resposta, levanta a mão.
(If you know the answer, raise your hand.)
O menino não respondeu, apenas encolheu os ombros.
(The boy didn't answer, he just shrugged his shoulders.)
Estás aborrecido? Não cruzes os braços.
(Are you upset? Don't cross your arms.)
Clothing and accidents
This rule extends beyond the body itself. It also applies to clothing you are currently wearing or putting on. When you use verbs like tirar a roupa (to undress), vestir (to put on), or calçar (to put on shoes), stick to the definite article.
You will also see this pattern when talking about injuries. With verbs like partir or quebrar (to break) and raspar (to scrape), the article is preferred. You might occasionally hear native speakers use possessives in these cases, especially in Brazil, but the definite article is always correct and highly natural.
Vou calçar as botas por causa da chuva.
(I am going to put on my boots because of the rain.)
Tira os sapatos antes de entrar em casa.
(Take off your shoes before coming into the house.)
Ela caiu e partiu a perna.
(She fell and broke her leg.)
Summary
Whenever you refer to body parts or clothing and the owner is clear from the context, drop English possessives like "my", "your", or "his". Instead, use the definite articles o, a, os, and as.
