- Do not walk around being tense all the time

- Watching the color green activates the parasympathetic nervous system (relax mode)

- Feeling exhausted after bodily activity or when sick (without hunger) means the body needs rest

- If possible, incorporate a more or less fixed sleeping cycle

- It's good to sleep in harmony with the day-night-cycle

- Go to sleep when feeling sleepy (at anytime)

- Wake up without a clock

- Try to sleep at a comfortable place without artificial noise and light

- The harder the surface of the bed, the better (unless it continuously hurts the body)

- Consider learning how to lucid dream as a way to improve mental health (and make spiritual progress)
