Nadia alternates between early shifts and night shifts each week. For six weeks, she uses slow, controlled breathing before trying to sleep, asks her flatmates to keep the corridor quiet while she is in bed, and uses her bed only for sleep.
Her mean sleep-diary results are shown in the table.
| Measure | Before the plan | During the final four weeks of the plan |
|---|---|---|
| Delay before falling asleep | 68 minutes | 35 minutes |
| Awakenings during each sleep period | 3.2 | 1.7 |
| Tiredness after waking, rated from 0 to 10 | 8.0 | 5.0 |
Explain how Nadia's plan may account for the pattern in the sleep diary and why it may not remove all her sleep difficulties.
