Do puts lose value over time?

I've been hearing a lot about puts in the financial world, and I'm curious about their value fluctuations. Could you clarify for me if puts typically lose value over time? How does the passage of time affect the worth of these financial instruments? Is it a gradual decline, or does it depend on market conditions and other external factors? Also, is there any strategy investors can employ to mitigate the potential loss in value over time? Your insights would be greatly appreciated.
