What is a Circadian Rhythm?
Our ‘body mechanics’ are doctors, for the most part, and if we went in to the doctor’s office for every squeak and groan our growing and ageing bodies may experience, we’d risk running up a lot of bills without feeling like a lot was accomplished or fixed. That’s why we go to the books, or internet, to do our own ‘machine’ research. That’s why you’re here now, for that matter. Something is bothering you this winter, and you’re not sure what it is.
If you’ve read at least one blog, ‘how to,’ or news release on Seasonal Affective Disorder, you’ve probably come across the phrase ‘circadian rhythm’ at least twice. Odds are that the author didn’t take the time to explain what that means, too. Well here’s a quick lesson in your Circadian Rhythm.
Best described as your ‘Biological Clock,’ the circadian rhythm is present in every living thing: Plants, animals, even Fungi. It’s Latin for “Circa” (Around) and “Diem” (Day). Which literally means ‘approximately one day.” It is measured by melatonin secretion and your core body temperature, and has been shown in humans to range from 23.5 to 24.5 hours in cycle.
A common ‘disruption’ of your circadian rhythm is commonly called ‘jet lag,’ and Seasonal Affective Disorder is also a symptom of a disrupted circadian Rhythm. Doctors fear that if a person’s biological clock is disrupted for too long, it could lead to cardiovascular disease, and a depreciation of melatonin could increase a patient’s risk of cancer.
So, in short, Seasonal Affective Disorder is a symptom of a greater problem which shouldn’t go ignored. Get out, get some sun or, in lieu of sunlight, purchase a SAD lamp. Your circadian rhythm will thank you.
