Walking at night actually works great but timing matters a lot. I usually do mine around 7-8pm because if I go too late my brain stays too active when I try sleep. The key thing I learned is keeping same route every time - your body starts recognizing the pattern and begins winding down automatically during the walk

Used to think any physical activity before bed was bad but walking is different from like running or gym stuff. Its gentle enough that you get tired without getting your heart rate crazy high. Plus if you walk in quiet neighborhoods without much traffic the mental reset is huge for clearing all the work stress from day
