Why do I wake up with swollen eyes?
Last updated September 3, 2026.
Lying flat lets fluid pool in the thin eyelid skin, so you wake puffy and deflate by mid-morning. Salt, alcohol, crying, and short sleep all add fluid; allergies add inflammation. The NHS maps swollen, itchy, or sticky eyelids to allergy, blepharitis, or conjunctivitis, and blepharitis specifically causes swollen, itchy lids with morning crusting, treated with daily lid washing. Cold compresses, a slightly raised pillow, and lighter late-night salt and alcohol handle the fluid version. Pain, fever, vision changes, one-sided swelling, or any lip, tongue, or breathing involvement escalates it.
What to do
- Cold flannel or chilled mask for a few minutes on waking.
- Sleep slightly propped up and ease off late salt and alcohol.
- Wash eyelids daily if you have crusting or sticking; that is the blepharitis pattern.
- See a GP for pain, fever, vision changes, or one-sided swelling; emergency care for lip, tongue, or breathing involvement.
