Here is some quick thing you can do to make dinner prep a relaxing part of your day.

Those exercises are based on some yoga practices.

Belly Breathing 

This exercise is quick enough to do while rice simmers.

1. Starred in a comfortable position. You can sit, lie flat, or stand.
2. Place one hand on your chest and one hand on your stomach below your ribs.
3. Draw a deep breath through your nose into your belly. Feel the hand on your belly rise. Your chest should not move.
4. Breathe out through your mouth, with your lips slightly restricted as through whistling. You’ll feel the hand on your belly drop.
5. Repeat this 3-10 times without rushing. Observe how you feel at the end. 

Full-body Breathing 

Try this while dinner is cooking in the oven. 

1. From a standing position, lean forward from the waist and bend your knees softly. Let your arms dangle close to the floor.
2. Inhale slowly and deeply. As you inhale, return to a standing position by rolling up slowly. Lift your head last. It should feel like you’re inflating. 
3. Back in your standing position, hold your breath for a few seconds.
4. Exhale and slowly return to the folded position. Repeat 3-5 times

Tell me how do you felt afterwards.
