What happens if I unstake Solana?

If I were to unstake my Solana tokens, what would be the consequences? Would I immediately regain access to my tokens, or would there be a delay? Will there be any penalties or fees associated with the unstaking process? Additionally, would my unstaking action have any impact on the overall Solana network or its staking mechanism? I'm curious about the specifics of the unstaking process and the potential implications it may have on my investment.
