Mindfulness meditation
A recent analysis of several high-quality studies (randomized controlled trials) concluded that mindfulness meditation programs help people fall asleep more easily and experience better-quality sleep overall.
Self-compassion
Self-compassion is something all of us could use right now, especially as lockdowns drag on and we find ourselves feeling more tired, unhappy, and unproductive than usual. Getting down on ourselves for perceived mistakes and flaws could exacerbate low-grade depression, which many of us already feel.
Gratitude
Feeling grateful is a good way to feel happier and strengthen our relationships. Now, it appears to help with sleep, too.
Forgiveness
For some people, forgiving others is hard—especially if you equate forgiveness with letting someone “off the hook” and condoning their harmful actions. But those who study forgiveness consider it to be not necessarily about healing relationships between people, but mostly important for ourselves, helping us to let go of grudges that decrease our personal well-being.
