Question 4 was “Why are you likely to wake up in the morning feeling exhausted if you are depressed?"
a . Because you aren’t getting enough exercise
b . Because you spend too much time in REM sleep due to over-dreaming at night
The answer is b. This is really important if you want to understand how depression works.
You are likely to wake in the morning feeling exhausted because when you ruminate negatively, you create emotional arousal that causes the release of stress hormones.
That night, in REM (dream sleep), you become emotionally aroused again as dreaming 'flushes out' the emotional arousal from your brain. That is why depressed people have higher levels of stress hormones, and also why you can wake up feeling exhausted.
Over-worrying or negative ‘rumination’ makes you dream more (depressed people dream up to three times more than normal). This is, quite literally, exhausting.
Also, serotonin production stops completely during REM sleep.
So, after a night of over-dreaming (even if you don’t remember your dreams) you’ll wake up with much lower levels of serotonin than normal. Daytime activity raises serotonin levels, making you feel better as the day progresses.
