What does Jonah 4:8 mean?

When the sun came up, God sent a scorching east wind. The sun beat down on Jonah's head so hard that he felt faint. He wanted to die and said, 'I'd be better off dead than alive.' Jonah 4:8 - Modern Text Bible

(Jonah is miserable without the plant's shade, and the harsh conditions make him wish for death again.)
