What to avoid, and why

The list makes sense once you know the reason

Confinement comes with a list of things to avoid, and out of context it can sound like superstition. In context it is the same one idea again: a depleted, open body is thought to need protecting from cold, in food and in the world around it. Here is the list, with the why for each.

Cold and raw food (生冷)

Salads, sashimi, cold fruit straight from the fridge, ice cream, iced drinks. Tradition holds that cold and raw food lets a chill settle into a body that cannot yet defend against it, troubles the digestion (the spleen and stomach, 脾胃), and slows the natural clearing of the first weeks. This is the belief that turns warm red date tea into the drink of the month and sends cold water to the back of the cupboard.

“Cooling” foods (凉性 / 寒性)

Here is a subtle one that confuses many people. In this tradition, foods have a “warm” or “cool” nature quite apart from their temperature. Watermelon, pear, and certain greens like bitter melon and white radish are considered “cooling,” and are usually set aside or eaten sparingly in the first weeks.

The nature can change with the cooking. Green papaya is the classic example. Raw, it is thought of as cooling and is kept off the list. Cooked warm into a soup with fish, it becomes a nourishing dish that tradition believes helps support a mother’s milk. Same papaya, different day, because how you prepare it changes what it is thought to do. If you have ever wondered why papaya soup is welcome but a raw papaya is not, that is the answer.

Cold water, wind, and cold hands

Warm drinks over cold ones. No cold draught blowing directly on you. And, in the strict tradition, not plunging your hands into cold water for chores. All of it is the same worry: keeping cold out of a body believed to be more open than usual. The modern, kinder version keeps the spirit (stay warm, be gentle with yourself) without the parts that make life harder than it needs to be.

Washing your hair

This is the rule mothers find hardest, and it is worth being honest about. Tradition asked women to wait, on the belief that a wet head and open pores invite cold in, and in a time of draughty rooms and no hot water, that was a real risk. Today, most mothers wash sooner, and the guidance becomes gentle rather than forbidding: warm water, be quick, dry your hair completely and straight away, and keep out of a draught while it dries. Care, not prohibition.

When “avoid” is not enough

Most of these are foods that are perfectly nourishing in another context. Avoiding them is a tradition, not a medical rule, and you will not harm yourself by having a slice of fruit. But there is a different kind of “avoid” that is not about tradition at all. If you have heavy or bright red bleeding, a fever, severe pain, a hot or painful breast, or thoughts that frighten you, those are not things to manage with warm food. Those are reasons to call your midwife, doctor, or health visitor the same day. Please do.
