In the sentences below is it mandatory the use of auxiliary-verbs, or they make sense even the manner they are written?

If your body's temperature falls below 20 degrees centigrade, you die.

If your body's temperature raises above 42 degrees centigrade, you die.

Or without commas:

If your body's temperature falls below 20 degrees centigrade you die.

If your body's temperature raises above 42 degrees centigrade you die.

They're fine without auxiliaries. Commas are recommended but not strictly required.

You should write rises rather than raises, though. There's no direct object here, so the intransitive verb rise is more appropriate than transitive verb raise.
