“What she found was that not only did counting sheep not make you fall asleep any faster, it actually made people take longer to fall asleep.”

The claim, plainly

A study conducted by sleep scientist Dr. Alison Harvey found that counting sheep does not help people fall asleep faster and actually increases the time it takes to fall asleep.

Assessment

Matthew Walker's claim that Dr. Alison Harvey's study tested counting sheep and found that it made people take longer to fall asleep is false. The referenced study, published by Allison G. Harvey and Suzanna Payne in Behaviour Research and Therapy (March 2002), tested 41 adults across three experimental conditions: imagery distraction, general distraction, and a no-instruction control group. The study contained no experimental condition testing 'counting sheep'. Furthermore, the study's hypothesis that general distraction would increase sleep onset latency (taking longer to fall asleep) was not supported by the data. Dr. Harvey mentioned sheep counting metaphorically in contemporaneous media interviews as an example of an ineffective, mundane distraction, which was later conflated in popular reporting and secondary summaries into an empirical finding of the study.

Harvey & Payne (2002), 'The management of unwanted pre-sleep thoughts in insomnia: distraction with imagery versus general distraction', evaluated imagery distraction against general distraction and a control group, with no condition specifically testing sheep counting.
The study explicitly found that its hypothesis regarding general distraction increasing sleep onset latency compared to control was not supported in the data.
References to sheep counting originated from Dr. Harvey's qualitative interview commentary in early 2002 comparing mundane imagery to engaging visualization, which media and secondary accounts subsequently misattributed as an experimental condition.

Walker: After a bad night of sleep, do nothing to compensate

“If you've had a bad night of sleep, here is my following best advice. Do nothing. And what I mean by that is, after a bad night of sleep, firstly, don't try to sleep it off by waking up any later than is natural. Don't sort of say, I'm going to then sleep in f…”

Walker: Average human endogenous circadian rhythm is roughly 24 hours 11 minutes

“It runs a little bit longer than 24 hours, it turns out. It's about 24 hours and I think 11 minutes for the average human adult we've calculated it as.”
