12th House in Astrology shows quality of sleep

One of the indications of the 12th House of our astrology chart is sleep and its quality. If you have benefit planets in the 12th or aspecting it, chances are you sleep well. Other way of seeing good sleep is the lord or ruler of your 12th House is exalted or sitting with a benefic or strong planet. Weak 12th lord or malefics like the Sun, Mars, Saturn and the nodes can cause difficulty in your sleep pattern. Simple remedies like mantras for the ruler of your 12th House can help this.
For Mars "Om nam Mangala Namaha", for the Sun "Om nam Surya Namaha", Saturn "Om nam Shani Yamaha"
I use Sidereal zodiac.
