It can be easy to get caught up in your tasks for the day and not set aside some time for you to relax and connect with nature. If you work from home, you may never step outside some days if you do not section off part of your day to intentionally do so.
I have found recently that even just 30 minutes at the park is a good break point in my day to let me step away from work for a short time and get some exercise outdoors.
