I think my stutter gets better in the summer

I think my stutter gets better in the summer Like over the summer I worked at a summer kids camp and I barely stuttered at all with the kids even though I was talking to them all the time. But now I stutter way more it seems. I think I’ve noticed this before about winter and fall. I don’t know if it’s actually because of the seasons or if it’s because I’m in school and that makes me more stressed, but I do often experience a lot of stress in summer and the kids camp was definitely stressful so idk. Does anyone else have this? Maybe something about the cold weather makes my body feel more tense and stiff which makes me stutter more?
