Rilassato vs. disteso
While both 'rilassato' and 'disteso' in Italian mean 'relaxed', they have subtle differences in usage and connotation.
Rilassato
'Rilassato' typically refers to a state of being calm, at ease, or free from tension, often in a casual or informal context.

(After a long walk, I feel very relaxed.)

Disteso
'Disteso' often implies a deeper sense of relaxation, suggesting a release of physical or mental tension, and can be used in more formal or serious contexts.

(His face appeared relaxed after meditation.)

Summary
While 'rilassato' is often used for everyday situations of feeling at ease, 'disteso' tends to imply a more profound state of relaxation or easing of tension, and can be applied to broader contexts beyond personal feelings.
