If you've noticed yourself yawning more, reaching for that second cup of coffe, or struggling to keep your eyes open in September , you're not alone. Many people feel unusuaaly tired during this season - and it's not just your imagination.

Changing Light and Sleep Patterns

As summer fades, the days get shorter. less dayligth means your body produces more melatonin, the hormone that makes you sleepy. At the same time, your internal clock - or circadian rhythm-has to adjust. That transition can leave you feeling groggy, even if your're sleeing enough hours. 

Back-to-School Routines and Stress

September often brings major routine changes: kids going back to school, earlier alarms, busier commutes, and jam packed schedules. Even adults without school aged kids can feel the ripple effect- more traffic, longer workdays, and seasonal deadlines.  All of this adds mental and physical stress, which translates into fatigue.

Fall Allergies

September is also prime time for ragweed pollen and mold spores. If you have seasonal allergies, your immune system is already working overtime. Symptoms like congestion, sneezing, and itchy eyes can disrupt sleep, leaving your more drained during the day.

 

 

Emotional Shifts

The change of seasons can affect your mood, too. Some people start feeling the early signs of Seasonal Affective Disorder (SAD) even in the late summer or early fall. That low mood or lack of motivation can look a lot like fatigue.

How to Beat September Fatigue

The good news: small changes can make a big difference. Try:

  • Getting outside for at least 20 mintues of natural light daily.
  • Sticking to a consistent bedtime and wake-up schedule.
  • Staying hydrated and fueling with balanced meals (not just carbs)
  • Managing allergies with medications or air filters if needed.
  • Talking to a provider if fatigue feels overwhelming or persisent.
