Why you wake up with puffy eyes
Fluid, salt, sleep, and allergies, the puffiness that is not a circle at all.
Morning puffiness is often mistaken for dark circles, but it is a separate, mostly benign phenomenon, and understanding it saves people from treating the wrong thing.
When you lie flat for hours, fluid pools in the loose tissue under the eyes; gravity drains it once you are upright, which is why puffiness fades through the morning. Salt, alcohol, poor sleep, and crying all increase the fluid load. Allergies are a major and underrated contributor: chronic rubbing and histamine-driven swelling both darken and puff the under-eye, and treating the allergy often does more than any cream.
The transient, fluid kind of puffiness responds to simple measures, sleeping with the head slightly elevated, reducing evening salt and alcohol, a cold compress, and addressing allergies. Persistent bags that do not change through the day are structural fat, a different issue that creams and cold spoons will not touch.
