Malay culture holds a belief in Hantu Meroyan; a spirit that resides in the placenta and amniotic fluid.  When this spirit is unsatisfied and venting resentment, it causes the mother to experience frequent crying, loss of appetite, and trouble sleeping, known collectively as "sakit meroyan". The mother can be cured with the help of a shaman , who performs a séance to force the spirits to leave.  Some cultures believe that the symptoms of postpartum depression or similar illnesses can be avoided through protective rituals in the period after birth. Chinese women participate in a ritual that is known as "doing the month" (confinement) in which they spend the first 30 days after giving birth resting in bed, while the mother or mother-in-law takes care of domestic duties and childcare. In addition, the new mother is not allowed to bathe or shower, wash her hair, clean her teeth, leave the house, or be blown by the wind. 
Dear Moms, I am 65 years old and went through terrible post partum anxiety/ depression after my two children were born 30 plus years ago. At that time I felt as if my Life was over. No one even knew what PPD was. Now I am a new Grandma to an 8 month old. It has been the purest of joy, healing, serenity, knowing. But here is some perspective from my lifetime of experiences. I have been involved in alternative healing ( Reiki level one trained) and related healing for 15 years, also . In pre-med bio, microbiology, science teacher, and support group leader 12 years.
In 2003 Barry Eichengreen laid out a credit boom theory as a cycle in which loans increase as the economy expands, particularly where regulation is weak, and through these loans money supply increases. Inflation remains low, however, because of either a pegged exchange rate or a supply shock, and thus the central bank does not tighten credit and money. Increasingly speculative loans are made as diminishing returns lead to reduced yields. Eventually inflation begins or the economy slows, and when asset prices decline, a bubble is pricked which encourages a macroeconomic bust.
