There is a thing they call stamina in the game and when ur screen turns red that means your stamina is being reduced and damage will start to be taken to your health. The stamina recharges while you hide from enemies etc, but if u take damage after the screen is red this health does not regenerate unless u pick up a health pack. That's how it works.
