“Even when preparing for a Test match it’s important to have a little downtime and switch off, even if it’s just for an hour over your Sunday morning coffee,” Smith tweeted.
“This is not something that comes easy to me as I find it hard to stop visualising the game or shadow batting!”
The 31-year-old right-handed batsman goes into the Test series on the back of some impressive knocks in the limited-over leg of India’s tour.
While he only scored 82 runs in the three-match T20I series, Smith smashed back-to-back centuries off identical 62 balls in two out of the three ODIs. He ended the ODI series with 216 runs at an average of 72.
