人冷致病心冷致命
[rén lĕng zhì bìng xīn lĕng zhì mìng]
'Chillness Makes People Ill; Cold Heart Kills' means that physical illness comes from being cold physically but having a cold heart is much worse because it leads to inner death which might mean losing the passion for living. This shows one is concerned about mental and emotional well-being more deeply than the surface health condition.
