Can I Unstake Solana anytime?

Excuse me, I was wondering if you could clarify something for me regarding staking Solana. I've heard that staking can be a great way to earn rewards, but I'm concerned about the flexibility of my investment. Is it possible for me to unstake my Solana at any time, or are there certain conditions or timeframes that I need to be aware of before committing my funds? I appreciate your help in understanding this aspect of staking Solana.
