Most people know they should replace their mattress every several years, but many overlook another important part of a healthy sleep environment: the pillow.
Your pillow supports your head, neck, and spine for approximately one-third of your life. Over time, even the highest-quality pillow loses its shape, collects allergens, and becomes less supportive. An old pillow may contribute to neck pain, headaches, allergies, and poor sleep quality.
If you've been waking up feeling stiff or constantly fluffing your pillow throughout the night, it may be time for an upgrade.
