Nope, for one thing, the country I live in never implemented anything resembling strict lockdown measures (there were some restrictions on opening hours for businesses, types of businesses that could open and car traffic in city centers) and for another thing, at all times, even during the time least welcoming to going out, I made sure to simply go for solitary walks in parks, streets and public areas while avoiding any crowds. I know that in some countries (disgracefully in my view) even leaving home for a solitary walk or with family you live with anyhow was forbidden, but where it isn't anyone who's been feeling more than a bit claustrophobic should sincerely just go out and get some air on a regular basis. It is possible to do this without overly exposing yourself, and it can be done in the company of any people you in any case might share your home and intimate air with.
