Flaxseed is a popular choice for eye pillows due to its unique properties that make it suitable for providing relaxation and comfort. Here are some reasons why flaxseed is often used in eye pillows: Weight and contouring: Flaxseeds are small and have a smooth texture, allowing them to evenly distribute weight across the eye area. Their size and shape enable them to conform well to the contours of the face, providing gentle pressure without being too heavy or uncomfortable. Heat retention: Flaxseeds can be heated and retain warmth for a significant amount of time. A warm eye pillow can help soothe tired eyes, relieve sinus pressure, and promote relaxation. Cold therapy: Flaxseeds can also be chilled in the freezer, providing a cooling effect that may help reduce puffiness, soothe headaches, or alleviate pain from minor injuries. Aromatherapy: Flaxseeds can be mixed with dried herbs or essential oils, like lavender or chamomile, to add an aromatherapy component to the eye pillow. These scents can enhance relaxation and stress relief. Hypoallergenic: Flaxseeds are a natural and hypoallergenic filling option, making them suitable for people with allergies or sensitivities to synthetic materials.
