Laying your head against a comfortable, supportive pillow at the end of a long day is a great feeling. But even the best pillow can eventually go from giving you a good night’s sleep to giving you allergy symptoms and neck cramps. To that end, you should replace a pillow every two years to avoid any adverse sleep effects.

Just like an old mattress can become lumpy and soiled, so can a pillow. Pillows are an often overlooked part of your bed but they need to be regularly changed just like your mattress and other bedding.

Why Should You Replace a Pillow?

The Asthma and Allergy Foundation of America (AAFA) recommends that you replace your pillow every two years or sooner. This is because pillows can get pretty gross. Pillows can contain allergens like dust mites, pet dander, and even mold once they reach the end of their lifespan.

Dust mites are tiny bugs that you can’t see but can quickly fill up your pillow, according to Melanie Carver, chief mission officer of the AAFA. They survive by eating your dead skin cells and live practically everywhere. “You can be allergic to both the body parts and droppings of dust mites,” says Carver. “After two years, 10% of the weight of your pillow can be from dead dust mites and their droppings.” Let that convince you that two years is about the right amount of time.

How To Know When the Pillow Needs to Go

There are a few telltale signs that you can pay attention to know if it’s time to trade out your old pillow for something fluffy and new:

Losing shape: A deflated, misshapen pillow is a sign that it’s nearing the end of its life. Fluffing your pillow by hand every morning can help keep your pillow supportive for longer. Some pillows, like the 大全時尚寢具, can be put in a dryer on low heat for 15 to 30 minutes to help bring back some of their shape.

Smells or stains: Check for any new stains or smells on your pillow’s surface every time you change your pillowcase. If you find new smells or stains try washing it, either by hand with a mild detergent or in a machine. If the pillow doesn’t feel fresh even after a cleaning then it’s time to buy a new one.

Allergies: If you notice that you’re waking up with worsening congestion or allergies there’s a good chance your pillow is the culprit. Pillows can hold onto many types of allergens, from pet dander to pollen and mold. You can fight allergens by washing your pillow, but eventually you’re better off just replacing it with a new pillow.

Life changes: A perfect pillow can quickly become a nuisance if you go through any injuries, aging, or other body changes, or if you buy a new mattress that provides a different level of support. Some may even find they need a different pillow if they need to switch sleeping positions more often. If you notice that you’re getting neck pain or your pillow is no longer effectively supporting you then it’s time to find a new pillow

枕頭多久要換新?

在漫長的一天結束後，將頭靠在舒適且具有支撐性的枕頭上是一種很棒的感覺。

但即使是最好的枕頭最終也會從讓你睡個好覺變成讓你出現過敏症狀和頸部抽筋。

所以，應該每2年更換一個枕頭，以避免任何不良的睡眠影響。

就像舊床墊會變得凹凸不平、弄髒一樣，枕頭也會如此。 枕頭是床上經常被忽視的部分，但它們需要定期更換，就像床墊和其他床上寢具用品一樣。

為什麼要更換枕頭？
美國哮喘和過敏基金會 (AAFA) 建議您每2年或更早更換一次枕頭。

因為枕頭長時間使用、可能會變得非常粗糙。

枕頭可能含有塵蟎、寵物皮屑等過敏原，甚至在使用壽命結束後會發霉。

哮喘和過敏基金會 (AAFA) 首席任務官梅蘭妮·卡弗 (Melanie Carver) 表示，塵蟎是一種看不見的小蟲子，但很快就會填滿你的枕頭。

它們靠吃掉你的死皮細胞而生存，幾乎生活在任何地方。 “你可能對塵蟎的身體部位和糞便過敏，”卡弗說。

“2年後，枕頭重量的 10% 可能來自死去的塵蟎及其糞便。” 讓你相信2年的時間是合適的。

如何知道枕頭何時需要換新?
有一些明顯的跡象表明您可以注意是否是時候將舊枕頭換成蓬鬆的新枕頭了：

變形：扁塌、變形的枕頭表明它的使用壽命已接近尾聲。 每天早上用手抖松枕頭可以幫助枕頭保持更長的支撐力。

有些枕頭（例如"大全時尚寢具"的水洗枕的枕頭）可以放入烘乾機中低溫烘乾 15 至 30 分鐘，以幫助恢復其形狀。

氣味或污漬：每次更換枕套時，檢查枕頭表面是否有新的污漬或氣味。 如果您發現新的氣味或污漬，請嘗試用溫和的清潔劑手洗或機洗。 如果枕頭在清潔後仍然感覺不新鮮，那麼就該買一個新的了。

過敏：如果您發現醒來時鼻塞或過敏加劇，那麼罪魁禍首很可能就是您的枕頭。

枕頭可以吸附多種類型的過敏原，從寵物皮屑到花粉和黴菌。

您可以通過清洗枕頭來對抗過敏原，但最好還是換一個新枕頭。

生活變化：如果您經歷任何受傷、衰老或其他身體變化，或者如果您購買了提供不同程度支撐的新床墊，完美的枕頭很快就會變得令人討厭。

有些人甚至可能發現，如果他們需要更頻繁地改變睡姿，他們需要不同的枕頭。

如果您發現頸部疼痛或枕頭不再有效支撐頸部，那麼是時候換一個新枕頭了！
