The start of the 2020 Grand Prix season has been delayed until July by the coronavirus, with 10 races out of what should have been a record 22-event championship either cancelled or postponed.
Hamilton, however, is trying to make the most of the downtime ahead of his bid for a record-equalling seventh world title.
"There have been times in the past five years that I thought a rest would be good for body and mind," he said in a video released by his Mercedes team on Saturday.
"For an athlete in their prime, it's never a good thing to step away for a year but we have been handed a part-sabbatical, which I am enjoying."
The 35-year-old British driver added: "I feel fresher and healthier than ever."
Hamilton explained his enforced absence from the track was "almost a blessing on one side because it gives you even more appreciation for the things you love and do" and had left him "excited for the future".
Hamilton has not been among the drivers taking part in online racing, although he said he had played Call of Duty online with fellow F1 drivers Pierre Gasly and Charles Leclerc.
The 2020 season is now set to start in July with the Austrian Grand Prix -- the first of several races scheduled to take place behind closed doors as a precaution against the spread of Covid-19.
Hamilton said the prospect of racing without spectators "gave me a really empty feeling because the fans make the race".
Nevertheless, he understood racing of any kind would be a boost for Grand Prix enthusiasts amid the pandemic.
"I don't know how exciting it's going to be for people watching it on TV but it'll be better than nothing."
