Minecraft wiki entry for Damage, associated text: A player submerged in powder snow sees a frosty frame slowly fade in at the sides of the screen and the FOV slowly decreases. After seven seconds (140 game ticks), the player's hearts change to a cyan frosty texture (), and the player begins taking damage at a rate of 1 HP every two seconds (40 game ticks). If the player leaves the powder snow block, the vignette slowly fades away. A frozen player moves slower than usual until the vignette fully fades away. This is controlled by the "TicksFrozen" data tag, which increases by 1 every tick (to a maximum of 300) for an entity within the powder snow block. It decreases at a rate of 2 per tick after the entity leaves the powder snow block. This is currently not a separate effect when used with commands such as /effect give freezing, and does not have its own unique art, particles, or potion.
