Cortisol also helps regulate your metabolism, sugar levels, and blood pressure. Your adrenal glands are controlled by your pituitary gland, another part of your endocrine system. Located in your head, your pituitary gland is the main controller of your endocrine glands. Abnormal signals can disrupt the amount of hormones that your pituitary gland tells your adrenal glands to produce.
In the average household of about 2-4 residents, carpet lifespan is usually about 3-5 years. It is by this point that most carpet fibers become old and frayed. Stains will also have sunk in, turning what started out as a pure white carpet into something graying and dull.
So...I think some carpet can last over 10 years or more. It depends on quality, how much it's used, and if there are little ones running on it. You might want to consider waiting until your kids are a bit older...either that or restrict was is allowed on the new carpet. 1 mom found this helpful.
