Hamilton opened a 30-point lead over Ferrari rival Sebastian Vettel with a surprise victory in Monza on September 2 and while some have questioned his jet-set lifestyle, the Brit says his focus is firmly on the final seven races of the season.
"As soon as I leave the races I'm able to switch off. I've got, obviously other things that I'm doing, and in between, trying to fit in the training, for example, in the last week, has not been easy," Hamilton told reporters on Thursday.
"But that's not really how every single week goes for me - it's just a hectic time for me with a lot going on in the outside world for me. I've travelled a lot more than I have all year long in these two weeks.

"It might be subconscious but I've not really thought about it [driving defensively]... at the moment there's no reason to change," the 33-year-old added.
"There are a lot of points still available so the approach is exactly the same as it has been all year long. It seems to be working, so we'll just keep that up for as long as we can.
"But we do expect there are going to be some difficult races ahead. Obviously Ferrari have been ahead of us for the past few races, so keeping up with them, if not passing them, is going to be tough."
