Stress hormones & sleep timing Quiz

About this quiz

What you’ll learn about stress hormones and sleep timing

Cortisol and other stress hormones don’t just affect how sleepy you feel—they can also nudge your body clock earlier or later. This quiz helps you connect hormone patterns with real-life sleep timing issues like early waking, bedtime “second winds,” and weekend schedule drift.

Each question has 4 options and there’s no timer, so you can think through cause-and-effect without rushing. You can also choose the question count and select an easier, harder, or mixed difficulty run depending on whether you want a quick refresher or a deeper challenge.

Skills you’ll practice

You’ll practice distinguishing normal daily cortisol rhythms from stress-driven spikes and understanding how those shifts influence melatonin onset and sleep pressure. Expect a mix of basics and applied items, with difficulty balanced by alternating straightforward definitions with scenario-based questions.

Identifying signs of a delayed vs advanced sleep phase linked to stress
Connecting late-day stress, caffeine, and workouts to bedtime alertness
Interpreting common sleep timing patterns (early waking, middle-of-night waking)
Choosing practical, low-risk schedule adjustments to stabilize timing
Spotting when “tired but wired” points to arousal rather than low sleep drive

Common pitfalls (and how the quiz avoids them)

A frequent mistake is assuming stress only causes insomnia, when it can also shift your sleep window earlier or later. Another pitfall is mixing up sleep duration with sleep timing; the quiz separates these ideas and revisits them across mixed-difficulty questions.

How the mixed difficulty is balanced

Mixed mode blends quick knowledge checks with a steady stream of applied situations so you’re not stuck in either trivia or overly technical detail. If you want more control, lower the difficulty for foundational concepts first, then increase it once you’re consistently recognizing timing patterns.
