I’ve noticed that after I work out for about an hour, that night I sleep better and wake up feeling more rested than when I don’t work out.
If you don’t have any workout equipment at home, and it’s too hot or cold to walk outside, then I would suggest finding a good home workout channel for beginners on YouTube, get a fan and blast it on you, or turn on your AC, and go to town for at least 30 min.
If you do have a lot of distractions, then this could be a good excuse to get a little me time, put on some music, light a candle, and relax for about 30 min.
Getting at least 6 to 8 hours of good sleep is probably the most important thing on this list that will help your stress levels go down.
