Tired-looking, puffy eyes are quite common as we age, thanks to weakening tissue and muscle in the eye area. But there are other culprits as well. Hormonal changes and diet, such as eating too much salt, can trigger fluid retention and swelling under the eyes, according to the Mayo Clinic. Lack of sleep, sleeping flat on your back, allergies, certain health conditions and genetics also contribute to puffiness. There are several steps you can take to refresh your eyes.
Play it Cool
According to the Mayo Clinic, applying cool compresses, like a washcloth dipped in cool water, for a few minutes while sitting upright can reduce swelling.
Sleep Technique
Keep fluid from gathering around your eyes by elevating the head of your bed or simply using extra pillows. Also try to get the recommended seven to eight hours of sleep a night.
Allergies
Consider seeing a specialist, such as an allergist, if your puffy eyes seem to materialize only at certain times. Puffy eyes may be a sign that you're having a reaction to seasonal allergens, such as ragweed and tree pollen, or even animal dander. Treatment options depend on the allergen, but include avoiding the trigger, over-the-counter medications, such as antihistamines and immunotherapy (allergy shots), says the Asthma and Allergy Foundation of America.
Address Serious Medical Conditions
While eye puffiness is usually just a cosmetic concern, it can sometimes signal a more serious health problem. Kidney and thyroid problems may cause swelling around the eyes, as can infection, according to the Mayo Clinic. Your doctor can order tests to make sure no trouble is brewing--especially if the eye puffiness is severe, doesn't go away or affects other parts of your body, such as your legs.
Cosmetic Treatments
Various cosmetic treatment options are available if you're not happy with your appearance, including laser resurfacing and chemical peels, which can tighten the skin around the eyes, and eyelid surgery (blepharoplasty). During blepharoplasty, a surgeon removes excess fat and sagging skin through an incision made just below the lashes or inside the lower lid.
