Thanks for sharing, very interesting! Iāve also been experimenting with some adjustments to my coffee intake recently. I do like the taste of coffee so I have been trying swapping to some good quality decaf beans and generally only one real coffee a day. Iāve definitely noticed some improvements in my sleeping. I have been thinking about giving it up completely but I donāt want to then just substitute it for some other drink that has its own issues.

Between this book and Michael Mosleyās āJust one thingā, Iāve decided that for me personally, coffee is for mornings only as caffeine takes about 10-12 hours to leave the bloodstream.
There are pros to coffee, including some beneficial health impacts on the brain so Iām not in a massive rush to stop drinking it.
Like you, Iām experimenting a bit more around intake.
I try to have my latest coffee by around 1pm which seems ok for me generally. Interestingly though, if I have been out late and need to drive home, I have occasionally had coffee late at night and have still slept well afterwards so the impact on sleep isnāt always as bad as I would expect.
The book goes into more detail on the impact to sleep and it wasnāt so much impacting the quantity of sleep but the quality.
Without giving too much of the book away, it was more about the type of sleep you get and the impact over time.
I think the impact over time is the key with a lot of things. You can do a lot of things once in a while and it wonāt do any real harm but they can be harmful if you keep it up over an extended period of time.
