When the Days Get Shorter: Protecting Your Mental Health This Fall
There is a point every October in Colorado when fall suddenly feels different.
The mornings are darker. The evenings arrive earlier. The aspens begin losing their leaves. Temperatures drop quickly once the sun goes down, and the long days of summer can start to feel surprisingly far away.
For many people, this part of fall is cozy and welcome. For others, the seasonal shift can come with changes in energy, sleep, motivation, and mood.
And sometimes, it is a little of both.
As the days get shorter, October can be a good time to ask yourself:
How am I actually feeling as the season changes?
Seasonal Changes Can Affect More Than the Weather
Our bodies respond to light.
Daylight is one of the strongest signals regulating our internal body clock, or circadian rhythm, which influences sleep, alertness, and other daily biological processes. As daylight decreases in the fall and winter, some people notice that they feel sleepier, less energetic, or simply a little different than they did during the summer.
A Healthline overview of daylight, sleep, and seasonal mood changes explains how reduced sunlight can affect circadian rhythms, sleep, mood, alertness, and even appetite.
This does not mean every change in mood during October is seasonal depression.
It is normal to have fluctuations in energy and motivation throughout the year. But paying attention to patterns can help you distinguish between a temporary seasonal adjustment and something that may deserve more attention.
1. Look for Daylight When You Can
One of the simplest things you can do during the darker months is spend some time outside during daylight hours.
That does not require a long hike or a perfectly sunny Colorado afternoon.
A short walk in the morning, stepping outside during lunch, drinking your coffee on the porch, or working near a window can all increase your exposure to natural light.
Research discussed in Healthline's review of natural daylight and sleep suggests that daytime light exposure—particularly earlier in the day—may help reinforce healthier sleep and wake patterns, even during cloudy winter months.
If you already know your mood tends to change every winter, it can be especially useful to pay attention to those patterns before January or February arrives.
2. Protect Your Sleep Routine
October is also a good month to become a little more intentional about sleep.
As mornings become darker, it can be tempting to sleep later. As evenings get colder, we may spend more time inside, on screens, or settling into routines that subtly shift our sleep schedule.
Try to keep your bedtime and wake time reasonably consistent, including on weekends when possible.
Other simple habits can help:
Get outside during the daytime.
Limit bright screens right before bed.
Keep your bedroom cool and dark.
Avoid relying on alcohol as a sleep aid.
Give yourself a predictable wind-down routine.
You do not need perfect “sleep hygiene.” The goal is simply to give your body a little consistency as the environment around you changes.
3. Keep Moving—Even When the Weather Changes
One of the sneaky things about fall is how easily our activity levels can decrease.
Maybe you were walking after dinner during the summer, spending weekends outside, gardening, swimming, or simply getting more movement because the days were longer.
When darkness arrives earlier, those habits can disappear without us really noticing.
You do not have to replace summer activity with an elaborate exercise program.
A lunchtime walk, a short workout at home, walking while your child is at practice, taking the stairs, or finding an indoor activity you actually enjoy all count.
The goal is not to exercise perfectly. It is to avoid letting the seasonal transition quietly remove movement from your life altogether.
4. Stay Connected When Staying Home Gets Easier
Cool weather naturally pulls many of us indoors.
There is nothing wrong with a quiet evening at home. In fact, slowing down can be restorative.
But there is an important difference between choosing rest and gradually withdrawing from people and activities that usually make you feel good.
Notice if you are repeatedly canceling plans, avoiding calls or messages, losing interest in activities you normally enjoy, or finding that staying home feels less restorative and more isolating.
Sometimes a small amount of intentional connection—a walk with a friend, dinner with family, attending an activity, or simply calling someone—can help interrupt that pattern.
5. Notice Patterns Instead of Judging Them
If you feel less energetic in October, the most useful response usually is not:
“Why can't I just get it together?”
Try instead:
“Is this different from how I normally feel?”
You might notice:
You are sleeping significantly more but still feel tired.
Getting out of bed has become harder.
Your motivation has dropped.
You have lost interest in things you usually enjoy.
You are eating differently or craving carbohydrates more often.
You feel increasingly withdrawn, irritable, anxious, or down.
Concentrating feels noticeably harder.
Those observations are information—not a personal failure.
When Is It More Than the “Winter Blues”?
Seasonal affective disorder, or SAD, is a form of depression with a recurring seasonal pattern. Symptoms most commonly begin during the fall or winter and improve during the spring.
According to the American Psychiatric Association, about 5% of U.S. adults experience SAD, and symptoms can last for a substantial portion of the year. American Psychiatric Association
Symptoms can include:
Persistent sadness or depressed mood
Loss of interest or pleasure in activities
Low energy or fatigue
Difficulty concentrating
Changes in sleep
Changes in appetite or weight
Social withdrawal
Feelings of hopelessness or worthlessness
Winter-pattern SAD can also be associated with increased sleep, fatigue, overeating, and greater withdrawal from social activities. This medically reviewed Healthline guide provides an approachable overview of symptoms, causes, and treatment options.
Importantly, SAD is treatable.
Treatment may include psychotherapy, medication, bright-light therapy, or a combination of approaches depending on the individual.
If you are considering a light box because you have experienced seasonal symptoms before, it is worth discussing that with your healthcare provider rather than simply buying the brightest lamp you can find. Light therapy is an established treatment for seasonal depression, but it is not appropriate for everyone and should be used thoughtfully. Healthline has a helpful overview of light therapy and SAD.
You Don't Have to Wait Until Winter
One of the advantages of recognizing seasonal patterns is that you do not have to wait until you feel significantly worse to address them.
If you know that November, December, or January tend to be difficult months for you, October may actually be the right time to check in.
That might mean strengthening your routines, reconnecting with therapy, reviewing medications with your psychiatric provider, or simply talking about what you have noticed in previous years.
The same is true even if your symptoms do not fit neatly into seasonal affective disorder.
Persistent anxiety, depression, irritability, sleep disruption, burnout, or difficulty functioning deserve attention regardless of the season.
