There is no objective standard as to what is a “chumrah”. If a certain practice goes beyond the plain language and common understanding of the parameters of a halacha and “going the extra mile” makes you feel stronger in your emunah, than to you, its not a “chumrah”, since you’ve already move the baseline (both intellectually and spiritually) to your practice. To you, its “what you do”; to others, “its a chumrah”.
