There are multiple excellent reasons for exercise. I write about them constantly.
One I rarely talk about is the fact that it helps me (and most people) sleep soundly.
I have a lot of energy. I’m a pretty energetic person. I’m actually really aware of my energy level because it’s a good indicator of my inner mood. If I’m exhausted midday, it’s likely because I’m doing something I don’t want to be doing. If I’m sleepy at night just before bed, it’s been a good day of accomplishments. If I’m still anxious when I’m going to sleep, odds are I didn’t exercise and/or be productive enough that day.
Exercise, for me, is the opportunity to not only clear my mind and gain some perspective on what does and does not actually need to be done in the day. It also gives me a place to let out some of the pent up steam from various projects or interactions throughout the day. It energizes me if I’m feeling drained (and know it’s not from lack of sleep) and it calms me for the rest of the day.
I use my energy level as an indicator. And it typically directly corresponds to my exercise consistency.
Yet another reason to add to the long list of why getting up and getting moving is good for you.
