To unwind means to relax and let go of stress or tension after working hard or feeling wound up. After a long day at school, you might unwind by reading a favorite book, playing with your dog, or shooting baskets in the driveway. The word suggests releasing the tightness you've been carrying, like letting out a deep breath you didn't know you were holding.

The word comes from the literal act of unwinding thread from a spool or unwrapping something coiled up. Think of a yo-yo string that's gotten tangled: when you unwind it, you're reversing the twists until it's straight again. Your mind and body can work similarly. When you're stressed or concentrating hard, you're like that wound-up string. Taking time to unwind helps you return to a more relaxed state.

Different people unwind in different ways. Some like quiet activities such as drawing or listening to music. Others prefer running around outside or talking with friends. Athletes unwind after intense games. Teachers unwind after busy school days. Everyone needs time to unwind.
