Thank you DavidPS.

@DavidPS good find David! Thank you

For the objective of the study of lowering hypertension, taking aspirin at night would be preferred. Can it be assumed that for some, morning may still be better, e.g. those with lower BP, and maybe lower pulse?

Some peculiar things are supposed to happen to the vasculture while we sleep. Or maybe it's just while we're horizontal. Vascular tone relative to blood volume. Or something.

I'll refresh and come back with receipts.

This is another instance of one size does not fit all.

Despite some suggestions in the text, this was not a high blood pressure study. Do the reported blood pressure numbers look significantly different to you?

@ThinPicking - I wish you the best of luck with your quest. I looked and I could not determine what was going on.

I did notice that aspirin at night suppressed the spike in renin activity that was seen with aspirin in the morning. I do not know if that spike was caused by aspirin in the morning or not; there was no graph showing the effect of no aspirin.

Hint - I noticed that the renin activity shown with aspirin in the morning seemed to coincide with the well known morning cortisol spike. Does aspirin at night suppress this response?

I did not dig into the study, but was basing my question off of the Discussion you posted, where they say blood pressure was reduced:

"Discussion
...Our main finding is that aspirin administered at night compared with intake in the morning statistically significantly diminished plasma renin activity over 24 hours..."

I feel wiped out after night aspirin, and my question was an attempt to avoid lowering blood pressure, by taking it in the morning. I may be able to answer my own question with the chart you provided, which shows the greatest non-lowering advantage in BP was at night, from a morning dose of aspirin, with smaller advantages in the morning. So, if I'm interpreting this correctly, a slight advantage with morning dose with regard to BP not going too low.

@ThinPicking Thanks for the info. Please don't trouble yourself too much.

@DavidPS - Thank you. I made the switch from aspirin in the morning to aspirin in the evening. It took almost 4 weeks to notice the sleep benefits.
