Questions & Answers about Cuando me siento cansado, sé que hay que hacer una pausa corta para respirar profundo.
Both are correct, but they’re not identical in nuance.
- Estoy cansado = I am tired (a simple state, just describing how you are).
- Me siento cansado = I feel tired (focuses more on your subjective feeling, what you perceive in your body/mind).
In many contexts you could swap them, but me siento cansado sounds closer to “I can feel that I’m tired” or “I feel tired,” which fits well with the idea of noticing you need a break.
With sentirse + adjective, the adjective must agree in gender and number with the person speaking:
- A man: Me siento cansado.
- A woman: Me siento cansada.
- Several men / mixed group: Nos sentimos cansados.
- Several women: Nos sentimos cansadas.
So a female speaker would say me siento cansada in this sentence.
