Today, we're going to talk about how to treat puffy eyes. Step 1: Think about why you might have puffy eyes. The commonest causes are crying, being stressed and being overtired or simply hormonal changes. However, another cause as to why you might be getting them is due to allergies. Step 2: Things to try at home. Remember that puffy eyes are due to fluid in that area, so anything that causes constriction is going to help. The key to causing constriction is going to be putting something cold onto the eyes. That's why cool cucumbers help, that's why if you put some spoons into the fridge and then take them out and pop a cold spoon on each eye, that should help reduce some of the puffiness. Also using a teabag, letting it cool and then popping it onto the eye can be a really good thing to do because teabags contain tannin and caffeine which can again cause constriction. Step 3: If you think your puffy eyes might be due to allergy, take a slightly different approach. When you're outside, wear sunglasses or some kind of eye protection that also has wrap-around feature around the side to stop allergens from getting into contact with the eyes. In addition, if your eyes are becoming very itchy and gritty after being outside, that might suggest an allergy, and then, antihistamine eye drops that you can buy over the counter might also work. Another point to think about is your make-up or your face washes, those things contain a lot of ingredients, some of which your skin might be reacting to, even though it hasn't reacted to that before, so one thing I would suggest is trying stopping all products for a couple of days and seeing if that improves your symptoms. Step 4: When to see your doctor. If you're actually feeling unwell with puffy eyes, then that's the time to go and see your doctor, the reason being that there are a few conditions that can link the two, your doctor might want to check your blood pressure, they might want to check your urine, they might want to do some blood tests to look at your thyroid and your kidney function. So, in conclusion, that's how to treat puffy eyes. .
