Beat the October Slump - How the Clock Change Impacts Mental Health

The extra hour in bed on Sunday morning sounds like a treat - until Monday hits, and darkness arrives before you’ve even left your desk.

If you notice a drop in your mood, motivation, or energy during this time of year, you’re not alone. Seasonal Affective Disorder (SAD) - often referred to as seasonal depression - affects millions of people every autumn and winter. Understanding how this shift impacts us is the first step toward reclaiming your energy and staying connected to the outdoors.

The Science Behind the Seasonal Slump

Why does a reduction in daylight affect us so deeply? It all comes down to our biology:

• Disrupted Circadian Rhythm: The sudden reduction in daylight hours throws off your body's internal clock, which regulates sleep, mood, and energy levels.

• Serotonin Drop: Sunlight stimulates the production of serotonin, the hormone responsible for boosting mood. Less sunlight often leads to lower serotonin levels.

• Overproduction of Melatonin: Darker days prompt your body to produce more melatonin, the sleep hormone, leaving you feeling sluggish and fatigued throughout the day.

When energy levels plummet, going outside is often the first routine we sacrifice. We swap outdoor walks, weekend hikes, and evening runs for blankets and screen time. Paradoxically, staying indoors deprives us of the exact remedy our bodies are craving: natural light and fresh air.

The Vicious Cycle: Why Missing Outdoors Makes It Worse

When seasonal depression takes hold, it creates a feedback loop:

• You feel tired and low, so you stay indoors where it’s warm and comfortable.

• Staying indoors reduces your light exposure, further lowering your serotonin and throwing off your sleep cycle.

• Your mood worsens, making the thought of stepping outside feel even more overwhelming.

Breaking this cycle doesn't mean forcing yourself through grueling multi-mile hikes in torrential rain. It’s about making small, intentional adjustments to capture daylight when it matters most.

5 Ways to Keep Getting Outdoors as the Days Get Darker

1. Harness the "Lunchtime Light"
Once the clocks change, evening daylight disappears almost completely. Shift your daily outdoor time to 1pm. A 20-minute walk during your lunch break offers peak daylight exposure, helping reset your circadian rhythm and boosting afternoon focus.

2. Reframe Cold Weather as an Adventure
The barrier to getting outside in autumn is often mental. Investing in a good waterproof layer, warm socks, and thermal layers removes the physical discomfort of cold and wet weather. As the Scandinavian saying goes: "There’s no such thing as bad weather, only bad clothing."

3. Start Morning Light Stacking
Try stepping outside within 30 minutes of waking up, even if only for 5 to 10 minutes. Early morning light exposure signals to your brain that the day has begun, helping suppress melatonin production and making it easier to fall asleep at night.

4. Find an Outdoor Accountability Buddy
When your internal motivation is low, external commitments help bridge the gap. Plan weekend walks with a friend, join a local walking group, or schedule regular park visits with family.

5. Lower the Bar for What Counts as "Outdoors"
You don't need to visit a remote mountain to reap the mental health benefits of nature. Sitting on a park bench, pottering in the garden, or walking around your local area all deliver sunlight and fresh air.

Final Thoughts

The seasonal transition into late autumn and winter can be tough, but you don't have to simply endure it until spring. By recognizing how daylight shifts affect your body and actively making space for outdoor time, you can protect your mental health through the darker months.

When the clocks change this weekend, use it as a reminder to prioritise getting outside - even just for a few minutes a day. Your mind and body will thank you for it.
