3. Inability to Nap
People with insomnia often cannot take naps during the day. If time allows, an insomniac will simply lie there awake with eyes closed. This has to do with a higher level of arousal that occurs in people with insomnia. This makes it easy to stay awake during the day, but hard to sleep at night. It likely relates to higher levels of neurotransmitters, or chemical messengers, that contribute to wakefulness. Like a bell ringing over and over, these prompts constantly prod an insomniac with a message to “Wake up!” and this compromises even the ability to nap in the day.
