(Good) sleep: i had a good nap few days ago and it energized me for a brief period. (Cold) shower: hours ago i took a semi-cold shower and i felt the best therapeutic relaxing shower. Afterwards i took a cup of coffee and it was one the most satisfying sip of coffee i had. Later my nostalgia and mindfulness increased. This didnt last long though. (Moderate) Exercise: i did a 1 minute set of jumping jacks and it gave me a bit of energy afterwards for a brief period of time. Have you tried them? Have they worked for you?
