If your bed sheets are making you itch or you develop any rashes or redness from them, it may be time to change your sheets because they may be triggering these allergy symptoms. Suppose your bed sheets are made of an absorbent material that traps heat and moisture. In that case, they can develop bacteria and other allergens that can affect you, especially if you have sensitive skin. It’s best to replace your sheets with sheets like ours, which are safe for sensitive skin.
