解説 desidratar in your Level:

At the A1 level, you should understand 'desidratar' as the opposite of 'beber água' (drinking water). Think of it in simple terms: if you don't drink water, you 'desidrata'. It's a word you might hear when talking about basic health or the weather. You likely won't use it much yourself yet, but recognizing it in a doctor's office or a health poster is important. Focus on the relationship between 'calor' (heat), 'água' (water), and 'corpo' (body). A simple sentence like 'Eu preciso de água para não desidratar' is a great start. You might also see it on food packaging, like 'leite desidratado' (powdered milk), which is a common item in many households. The goal at this level is just to associate the word with the lack of water.

desidratar 30秒で

Desidratar means to lose or remove water from a body, food, or chemical substance.
It is commonly used reflexively (desidratar-se) when referring to humans or animals becoming dehydrated.
The word is essential in medical contexts, culinary arts (dried fruits), and sports science.
Figuratively, it describes the weakening or depletion of resources, ideas, or political power.

The Portuguese verb desidratar is a technical yet common term that describes the process of losing or removing water. At its core, it is the opposite of hidratar (to hydrate). In everyday Portuguese, you will encounter this word in three primary contexts: medical/biological, culinary, and figurative. In a medical sense, it refers to the physiological state where a person's body does not have enough fluids to function correctly. This is a critical term in Brazil and Portugal, especially during the hot summer months where heat exhaustion is a concern.

Medical Context: When a doctor says a patient is starting to desidratar, it implies an urgent need for fluid replacement, often through intravenous means or oral rehydration salts.

Se você correr a maratona sem beber água, seu corpo vai desidratar rapidamente.

In the culinary world, the word is used for the preservation of food. To desidratar fruit involves removing its moisture to create snacks like dried bananas or apricots. This process is highly valued in modern healthy eating circles in Lusophone countries.

Culinary Usage: The act of removing water from food to extend its shelf life or concentrate its flavors.

Nós vamos desidratar estas maçãs para o lanche da tarde.

Beyond the physical, it can be used figuratively to describe something that is losing its vitality or substance. For example, a political movement might 'dehydrate' if it loses supporters. Understanding this word requires recognizing that it is not just about being 'dry' (secar), but about the active loss of essential internal moisture.

Environmental Context: Used to describe plants or soil losing moisture due to extreme drought conditions.

O sol forte pode desidratar as folhas das plantas em poucas horas.

É perigoso desidratar durante uma trilha na floresta.

O cozinheiro decidiu desidratar os tomates para fazer um molho concentrado.

Using desidratar correctly depends on whether you are talking about something you are doing to an object or something happening to a living being. When you use it as a transitive verb, you are the agent causing the water loss.

Transitive Usage: Subject + desidratar + Object. Example: O calor desidratou a fruta.

Eu vou desidratar cogumelos para a sopa.

However, when talking about a person or animal becoming dehydrated, Portuguese speakers almost always use the reflexive form desidratar-se. This indicates that the state of dehydration is occurring within the subject.

Reflexive Usage: Subject + se + desidratar. Example: Ele se desidratou no deserto.

Cuidado para não se desidratar durante o treino.

You can also use the past participle desidratado as an adjective. This is extremely common in medical diagnosis and food labeling.

Adjective Usage: Describes the state resulting from the process of dehydration.

A criança chegou ao hospital muito desidratada.

In more advanced contexts, you might see the verb used in the passive voice: A amostra foi desidratada em laboratório. This is typical in scientific papers. It is important to note the spelling: it uses 's', not 'z', following the root 'hidra'.

O processo químico serve para desidratar a substância.

Não deixe a pele desidratar no inverno; use hidratante.

You will hear desidratar frequently in Brazil and Portugal, though the contexts might vary slightly. In Brazil, due to the tropical climate, health campaigns often use this word to warn citizens about the dangers of heatwaves. Radio and TV health segments will repeatedly say, 'Não deixe as crianças desidratarem.' (Don't let the children dehydrate). In gyms and sports centers, instructors use it to emphasize the importance of drinking water during intense training sessions.

Health Campaigns: Public service announcements regarding heat, hydration, and pediatric health.

O repórter alertou que o calor extremo pode desidratar os idosos.

In the kitchen, specifically in modern or gourmet cooking, you'll hear chefs discuss techniques to desidratar herbs or vegetables to create 'crisps' or powders. This has become a trend in Portuguese culinary shows like MasterChef Brasil.

Culinary Media: Cooking shows and food blogs explaining preservation and texture techniques.

Para esta receita, precisamos desidratar o manjericão.

Another common place is in skincare and beauty. Dermatologists use desidratar to describe skin that lacks water (distinct from skin that lacks oil). A common phrase in Portuguese beauty vlogs is 'Minha pele está começando a desidratar com este frio.'

O ar seco de Brasília pode desidratar rapidamente o organismo.

Vou usar o forno para desidratar algumas laranjas para decoração.

O atleta começou a desidratar no segundo tempo do jogo.

One of the most frequent errors for English speakers learning Portuguese is forgetting the reflexive pronoun when referring to people. In English, you can say 'I am dehydrating,' but in Portuguese, you must say 'Eu estou me desidratando.' Without the pronoun, it sounds like you are actively removing water from an external object rather than experiencing the process yourself.

The Reflexive Error: Incorrect: 'Ele desidratou no sol.' Correct: 'Ele se desidratou no sol.'

Se você não beber água, vai se desidratar.

Another mistake is confusing desidratar with secar. While secar means 'to dry' in a general sense (like drying clothes or hair), desidratar specifically refers to the loss of moisture from within the biological or chemical structure. You wouldn't 'desidratar' your hair with a towel; you would 'secar' it.

Secar vs. Desidratar: Secar is for surface water; Desidratar is for internal/cellular water.

Eu usei a toalha para me secar, não para me desidratar!

Spelling is also a pitfall. Many students try to write it with a 'z' because of the English 'dehydrate'. In Portuguese, it is always with an 's'.

É comum desidratar alimentos para conservá-los por mais tempo.

O calor intenso fez a planta desidratar e morrer.

Não podemos deixar o estoque de sangue desidratar (figurative: run dry).

Several words in Portuguese share a semantic field with desidratar, but they carry different nuances.

Secar: The most general term for 'to dry'. Used for hair, clothes, or the ground after rain.

Dessecar: A more technical or scientific term often used in biology or chemistry to mean 'to dry out completely'.

O cientista vai dessecar a amostra para análise posterior.

Murchar: Specifically used for plants or flowers that lose water and begin to wilt.

As flores começaram a murchar por falta de rega.

Ressecar: Used when something becomes excessively dry, often painfully or damageably, like 'dry lips' (lábios ressecados).

O vento frio pode ressecar a sua pele.

Precisamos desidratar a carne para fazer charque.

Beber álcool em excesso pode desidratar o corpo rapidamente.
