If you occasionally wake up with puffy eyes, you're not alone. It can be frustrating to see swelling in the under eye area first thing in the morning. This usually happens when fluid builds up overnight, especially if you've had too much salt, cried before bed, didn’t get enough sleep, or are dealing with allergies or other symptoms. Sometimes, puffiness under the eyes can also be linked to hormonal changes, poor diet, or certain medical conditions. The skin around the eyes is delicate, and small changes in your routine can affect how it looks in the morning. While home remedies like cold compresses or chilled tea bags can help reduce swelling, persistent puffiness may need a closer look. Things like dark circles, under eye bags, or eye puffiness that stick around could point to an underlying condition—or simply the natural aging of muscles supporting the eyelids and lower eyelids. If you’re wondering what causes puffiness and what actually works to reduce it, keep reading. This guide will walk you through causes, home remedies, and when to talk to a healthcare professional about other treatments like eye creams, chemical peels, laser resurfacing, or even eyelid surgery.
