*When we talk about things that are generally or always true, we can use:
If/When/Unless plus a present form PLUS present simple or imperative.
*Note that we are not talking about a specific event but something which is generally true.
In the condition clause, we can use a variety of present forms. In the result clause, there can only be the present simple or imperative.
