Always thought academic careers were always quite relaxed. Do research, disappear from the lab all afternoon. At least that's what I heard from some phD students. I suppose I wouldn't mind investing time reading up on science journals, I love reading science articles.
They're relaxed in the sense that you don't have a set schedule.
However, at the same time, they're not relaxed because you don't have a set schedule (so it's all on you, so sure, you have freedom, but you're also expected to get some top-notch research done).
For example most days I might have at most an hour to two hour long meeting I have to go to, however, I still have plenty of things I could and should be doing (I would consider a normal day spending at least 8-9 AM to 5-7 PM working on something or other).
At least at an R1 institution in the US, you're constantly reading research papers published in your sub-field/field, working on your own ideas, implementing your own research, analyzing data, emailing other researchers/communicating with people, and trying to get stuff published. So ultimately, it's not uncommon for us to work more than 50 hours a week (60-70 also isn't considered outside of the norm).
Of course, as long as you're getting your work done, you can totally go take an afternoon or day off if you need it, but I'd assume someone was a pretty **** researcher if they frequently just take afternoons off to slack off (that or they're literally a genius that doesn't need to put in work to do well).
TL;DR: Academia is great if you are self-motivating, have a high level of discipline, are good at working/learning independently and are good at dealing with stress.
