Implied (or implicit) textual evidence is suggested but not directly stated. When a reader comes across implied textual evidence, they have to:
put together details in the text to draw a conclusion and make educated guesses.

Laughing can relieve muscle tension and stress. Laughing also causes your brain to release hormones like endorphins. It also decreases stress hormones, which is a big help. When you laugh you also take deep breaths, so you end up getting more oxygen in our blood stream. Laughing can also improve your immune system, so you can fight off infections better. Try to expand on that. Hope that helps.
