Unwind is the all-purpose choice, fine in a magazine or an email. Rest is plain and calm and suits advice from a doctor. Recuperate is formal and means recovering after illness or hard effort, so it is more than just relaxing.

The adjectives split in a useful way. Relaxed describes how a person or place feels: swap for calm, laid-back, easygoing or at ease. Relaxing describes what causes the feeling: swap for soothing, restful or peaceful. A relaxing bath leaves you relaxed. For more, see the calm synonyms and peaceful synonyms pages.
The noun relaxation pairs with rest, leisure, downtime and recreation. In a rules sense it becomes easing or loosening: the easing of travel limits.
Near synonyms with a twist
