ease, peace
康 centers on a state of untroubled well-being: ease, comfort, and peace. It describes a condition free from disturbance or hardship.
康 is thought to combine 广 (building) with 隶, which may have originally depicted a hand holding a broom, suggesting cleaning and thus a peaceful, orderly state. The exact development is not fully certain.
Under a roof (广), a hand holds a broom (隶) to sweep away troubles, leaving a space of ease and peace.
For コウ, imagine a calm, peaceful cove (cove -> コウ) under the roof, where all is at ease.
