POV Changes According to Biome

Introduction So currently when you enter a biome, nothing happens to your point of view (POV). Here are some examples of POV changing according to biome.

Hot Environment POV In hot temperatures, the atmosphere begins to look wavy due to high heat. Things should render wavy when you enter say a desert or mesa biome.

Cold Environment POV In freezing cold environments I think a light blue vignette should appear at the borders of the screen. The effect would look very similar to the vignette present when you're too close to a world border.

Water POVs When you exit water, the POV should look as if you just dried your face off. Like a slight blur will take place, then it'll refocus. I also think this blur effect should happen when you enter the water as well.

Low Health POV When at two or lower hearts a panic red vignette will sprawl at the borders of the screen. This gives the player extra signals to show if they're low on health.

On Fire POV  After jumping into a fire or lava, currently a fire texture is just there, on your screen. This obscures the view and gets annoying very often. I think instead of this an orange red vignette will suit the circumstance better.
