We thank Dr Kawada for his comments on our study [
[1]
]. He raised some concerns regarding the effect of mid-day sleep on alertness and performance
as well as health outcomes. He based his concerns on three articles [

]. First of all, in these three articles the sample observed were healthy subjects
(in one paper [
[3]
] subjects were sleep deprived) and not hypertensive patients as it was in our study
[
[5]
]. So the characteristics of the sample are completely different. In addition, in the
articles of Takahashi M et al; [
[2]
,
[3]
], the authors assessed the effect of midday sleep only on alertness and performance,
which is a field completely different from our study, since we assessed the effect
of naps on blood pressure (BP) levels. The fact that midday sleep may have effect
on alertness and performance was not relevant with our study.To read this article in full you will need to make a payment
