What is the purpose of the blinds in Texas Hold'em poker and how do they affect the betting strategy of players?

In Texas Hold'em Poker, blinds are forced bets that two players have to make before the cards are dealt. The purpose of blinds is to create action and ensure there is money in the pot to play for. Blinds affect the betting strategy of players by putting pressure on them to play hands they might not otherwise play, especially when the blinds increase. Players need to be strategic in deciding when to play aggressively or conservatively based on their position relative to the blinds.
