In my recent deep dive into the subject, I've learned that Delayed Sleep Phase Syndrome (DSPS) is a circadian rhythm sleep disorder causing a shift in the biological clock, leading to late sleep and wake times. This disorder can significantly impact physical health, leading to a lack of energy, increased risk of cardiovascular diseases, obesity, and even diabetes. It's not just about feeling tired; it's about the toll it takes on our bodies. Sleep, it turns out, is one of the most important aspects of our health. So, if you're regularly staying up late and waking up late, it might be more than just a bad habit—it could be DSPS.
