I wonder how much of sleep research is affected by the difference in sleep quality between your own bed and a lab. Even if you're on vacation and the hotel bed is of exceptional quality, your brain knows that it's in a different environment and would naturally be on partial alert, at least for the first couple of nights.

Now imagine sleeping in a lab setting, knowing that your sleep data is being measured. Intellectually you know that you're not at any risk but there must be some difference in the architecture of your sleep.

I have been thinking about this too, not just for the bed but also measuring equipment like pulse-oxymeters you would wear during a study.
