Does it matter that the body is always sick and very residential?

Strictly speaking, it matters, but it is not the main aspect.

For example, if you have qi deficiency, then if the house is dark and damp, it will definitely be bad for your health.

If the body is too hot, the home is sunny, and there is no shady room, it will definitely aggravate the fever.

And there are some complicated situations in residential feng shui.

But unless you are particularly weak, it won't have much impact. For example, if we live in one house, it's okay for others to live.

To sum up for you, personal physical quality is the main reason.
