Lewis Hamilton says he is not concerned about his health and feels "in better shape" after suffering from dizziness at the end of the Hungarian Grand Prix.
Hamilton was visibly troubled on the podium in Budapest where he finished in second place following Sebastian Vettel's disqualification from the race.
After a four-week break, he's refreshed and is eager to extend his eight-point lead over Max Verstappen in the Drivers' Championship in Belgium this weekend.
"I've spent time over this period of time just trying to make sure I'm in the best shape," Hamilton told RacingNews65.com and other select members of the press.
"I do feel like I'm in better shape moving into the second half of the season and it's not a concern for me.
"In the world, we are still in this pandemic, and I still stress the importance of people staying safe. Naturally, as you move around, you're seeing people relaxing more and more, but the virus is still around.
"We'll continue to be in our bubble and I will continue to be focused on my health and making sure that I continue to get stronger through the rest of the year."
Hamilton, who admits Mercedes went through a "difficult patch" earlier in the season, says he has done a little bit of travelling over the summer but has been eager to get back behind the wheel of the car.
"The break was definitely much needed, but it felt too long at the end," said Hamilton. "I think I was definitely excited to get back to work and just miss working with the team and miss being in the car.
"I was definitely very keen quite early on just to get back. It seemed a little bit prolonged, but having that time is really precious naturally.
"So [you] just try to remain grateful for the spare time that you do have, and trying to use it to the best of my ability. Now we're back, which is great."
