Hey there! I just started doing shift work after my university courses, and I really like it.
That's good. So you haven't had to deal with insomnia or being too sleepy due to working weird times of the day?
No, that sounds awful. I didn't know that was a real thing.
Yes, it's considered a real disorder, and sometimes causes people to fall asleep at work.
That's rough. I hope I can deal with it better. My girlfriend is already on my back about my schedule.
You can avoid it by practicing good ''Sleep Hygiene'' such as using naps with care, avoiding alcohol and caffiene, and limiting worry (if you can)
Do you know how much hours should I sleep to practice good "Sleep Hygiene"?

Response: As an adult, the recommendation is to sleep 6-7 hours.
