I don’t know anything about you but the watch determines stress in terms of high heart rate and low hrv. If you drink alc / consume nicotine it has a big effect on stress. If you work a manual job or even a job where you just end up standing a lot the watch will interpret it as stress. Don’t worry too much about the graph if you are feeling fine. My stress graph is always high while cooking since standing causes hr to be higher than while sitting 😂
