I know, you are thinking morning is the time when everyone should go for a walk for their health and you are saying we should also do the same in evening.
Evening is the time when motivation level is very high. In evening, you can see birds fly. It feels very quiet and you are in peace. And of course, you should utilize your time in the evening. If possible, go out from your home and office to feel the joy of evening. It is the time where there is no high light and no dark. You can also buy something during your evening walk.
Some people do meditation in the morning as well as in the evening. You can also do the same. Try to do meditation in the open field such as park. You can also do this in your terrace.
Evening walk gives you mental pleasure as well as keeps your body healthy. It makes you very relaxed. You can think and work better. It is effective for every part of the body. So never forgot to go for a evening walk.
