When the Seasons Change, So Can Your Sleep and Mood
As the days get shorter and the weather turns cooler, many people notice shifts in their sleep, energy, and mood. You might have trouble falling or staying asleep — or find yourself sleeping more than usual and still waking up tired.
For some, these shifts are part of seasonal affective disorder (SAD), a form of depression that follows a seasonal pattern and most often appears in the fall and winter. But even without SAD, changes in daylight, temperature, and routine can nudge your body's internal clock out of rhythm and disrupt your sleep.
The good news: a few simple habits can help you stay steady through the darker months.
Get morning light
Try to spend time outdoors during the day, especially in the morning. Natural light is the strongest signal your body uses to keep its sleep-wake cycle on track, and it's in shorter supply this time of year. A morning walk does double duty — light plus movement.
Keep a consistent schedule
Going to bed, and most importantly waking up, around the same time every day — weekends included — helps anchor your body clock when the season is pulling it in different directions.
Keep moving
Regular activity supports better sleep, energy, and mood. It doesn't have to be strenuous — walking, stretching, or anything you enjoy counts, and it helps offset the temptation to stay indoors when it's cold.
Mind the time change
When we "fall back" to standard time in early November, even gaining an hour can throw off your sleep for a few days. The American Academy of Sleep Medicine recommends doing away with the twice-yearly clock change altogether in favor of permanent standard time, which keeps our internal clock better aligned with natural daylight. Until then, ease into the shift by adjusting your schedule gradually and getting plenty of morning light in the days that follow.
Eat well and stay hydrated
Give your body good fuel with a balanced diet and plenty of fruits and vegetables, and keep drinking water — you may feel less thirsty in cooler weather, but hydration matters all year.
Listen to your body
Some changes in sleep and energy are normal as the seasons change. But if you notice ongoing changes in your mood or sleep, or you're feeling unusually tired or down, it's worth paying attention. Talk to your doctor about your concerns - he or she can help determine whether your symptoms may be related to seasonal changes, a sleep problem or another condition.
