Many of us will start to notice subtle (and sometimes frustrating) changes in our sleep due to the temperature change. You might find yourself feeling sleepier earlier in the evening, struggling to wake up in the morning, or experiencing deeper but not always more restorative sleep.
The truth is, your body isn’t “off track” – it’s responding exactly as it was designed to. Autumn and winter naturally influence your internal rhythms. The key is learning how to support those changes rather than fight them.
Here’s what’s really going on and how to gently bring your sleep back into balance.
Why your sleep changes in autumn and winter
1. Less sunlight disrupts your internal clock
Your circadian rhythm – your body’s natural sleep-wake cycle – is heavily influenced by light exposure. Shorter days and longer nights mean less sunlight, which can delay your body’s signals for wakefulness and energy.
This often results in feeling groggy in the morning, wanting to go to bed earlier or a general dip in daytime alertness.
2. Increased melatonin production
Melatonin, your sleep hormone, is produced in response to darkness. With earlier sunsets, your body may start producing melatonin sooner in the evening and sometimes in higher amounts.
While this sounds helpful, it can actually make you feel sleepy too early, leave you feeling sluggish during the day and disrupt your usual sleep schedule.
3. Cooler temperatures affect sleep quality
Your body temperature naturally drops at night to help you fall asleep. Cooler weather can support this but if your environment becomes too cold (or too warm with heavy bedding), it can lead to restless sleep, frequent waking or difficulty getting comfortable.
4. Lifestyle shifts play a role
Autumn and winter often bring changes in routine:
- Less outdoor movement
- More time indoors (and on screens)
- Heavier meals and comfort foods
- Reduced social activity
All of these can quietly impact your sleep quality and energy levels.
5. Mood changes and seasonal slumps
Lower light exposure can affect serotonin levels, which influence mood. This can lead to low energy, increased anxiety, or even symptoms of seasonal depression – all of which are closely tied to disrupted sleep.
How to fix it (Gently and realistically)
Instead of trying to force your body into your summer routine, think of this as a seasonal reset. These small shifts can make a big difference:
Prioritise morning light
Getting natural light early in the day helps reset your circadian rhythm and signals to your body that it’s time to wake up.
Step outside within 30–60 minutes of waking, go for a short walk or have your coffee in the sunos open your curtains immediately in the morning.
Keep a consistent sleep schedule
Even though it’s tempting to hibernate, going to bed and waking up at consistent times helps stabilise your internal clock.
Pro tip: Aim for consistency over perfection – even on weekends.
Create a warmer, calmer night routine
Colder evenings are the perfect excuse to slow down. Use this to your advantage by creating a calming wind-down ritual.
You can try:
- Warm showers or baths
- Herbal teas
- Reading instead of scrolling
- Soft lighting (lamps over overhead lights)
Be mindful of evening light exposure
Artificial light – especially from screens – can delay melatonin production, confusing your body even more during darker months.
Try dimming lights after sunset, reducing screen time 1 hour before bed or using night mode on devices.
Adjust your sleep environment
Comfort is everything in colder months. You want to focus on layered bedding you can easily adjust, a slightly cool room temperature (around 16–19°C is ideal) and breathable fabrics to avoid overheating.
Support your energy during the day
Low energy can lead to naps, which then disrupt your sleep at night. Rather move your body daily (even a short walk counts), eat balanced meals with enough protein and stay hydrated (we often drink less water in winter).
Honour the slower pace
This season naturally invites more rest. Fighting it can leave you feeling more exhausted.
Instead of pushing through, allow yourself earlier nights when needed, build in more rest without guilt and focus on quality rest, not just productivity.
Your sleep changing in autumn and winter isn’t a problem – it’s a signal.
A signal to slow down.
To realign with natural rhythms.
To take better care of your energy.
When you stop resisting the season and start supporting your body through it, sleep becomes less of a struggle and more of a soft, restorative reset each night.
