Sleep Doctor Shares the Winter Sleep Fixes She Swears By to Beat Blue Monday

It starts slowly with darker mornings, heavier limbs and cancelled plans. Then it’s harder to get up, harder to focus, and harder to feel like yourself. This is what many call the “winter blues” – or, more recently, the rising sense of ‘winter dread’ that peaks in January and is often linked to Blue Monday. While it’s often blamed on mood or motivation, one of the biggest culprits might be hiding in plain sight: your sleep.

Here – sleep expert Dr Alanna Hare – has partnered with mattress brand, Sealy UK, to explore how small, science-backed changes in sleep habits, environment and routine can help you feel more alert and balanced through the cold season and reduce the low‑mood dip associated with mid-January.

What exactly is winter dread?

Winter dread is more than a dip in motivation – it’s a physiological response to shorter days and longer nights. “Daylight variation affects our circadian rhythm,” explains Dr Hare. “In darker months, your body struggles to suppress melatonin, the hormone that makes you sleepy.” With less morning light to ‘reset’ your body clock, energy levels, mood and sleep quality all start to suffer. Add cold, miserable weather and comfort-seeking habits like later mornings, and it takes a toll on your mood and stress levels – as well as your body clock. If you can work on the latter – you can see an improvement in your mood even during the bleak winter months.

1. Wake up to light

One of the best ways to reset your body clock is exposure to light as early as possible. “Natural light is the strongest signal to your brain that it’s time to wake up,” says Dr Hare. “Step outside soon after waking, open curtains fully, or use a dawn simulator lamp to help your body suppress melatonin and feel alert sooner.” This small shift can make January mornings feel less punishing and help counteract the winter‑blues slump.

2. Keep your room cool – even in winter

“It sounds counterintuitive, but overheating at night can reduce deep, restorative sleep,” says Dr Hare. “The body needs to cool slightly to initiate and maintain sleep.” Keep your bedroom between 16-19°C and avoid piling on too many thick blankets. Natural, breathable materials – from your mattress to your pyjamas – help regulate body temperature and prevent those 3 a.m. toss-and-turn moments. Mattresses featuring Geltex® – a patented, gel‑infused foam with an open‑cell structure – promote enhanced airflow and pressure relief, helping maintain a cooler, more consistent sleep climate throughout the night.

3. Support your body properly

A good night’s sleep isn’t just about comfort – it’s about alignment. “Research shows that when your body and spine are adequately supported, sleep quality and even the amount of deep sleep can improve,” says Dr Hare. A supportive mattress – such as the Sealy Posturepedic range – helps maintain spinal alignment and reduces the micro-awakenings that can leave you tired even after eight hours.

4. Ditch the viral ‘sleep hacks’

Scrolling TikTok for quick, ‘proven’ fixes? Dr Hare says most TikTok sleep trends do more harm than good. “Mouth taping, ice baths before bed or elaborate routines are often untested, unproven and can disrupt natural sleep physiology.”

5. Avoid weekend ‘social jet lag’

The Sunday lie-in might feel heavenly, but it’s sabotaging your Monday. “Going to bed and waking up at the same time each day stabilises your circadian rhythm,” explains Dr Hare. “Sleeping late on weekends shifts your internal clock, making it harder to fall asleep and wake up during the week.” Instead, keep a consistent sleep window, even on weekends – you’ll feel less groggy and blue on the Monday.

6. Move during daylight hours

It’s tempting to hibernate as it gets colder, but daytime movement helps build the “sleep pressure” your body needs at night. “Daytime activity – even walking or stretching – can significantly improve sleep quality,” says Dr Hare. Just avoid intense workouts too close to bedtime, which can delay sleep onset.

Winter dread isn’t just emotional. It’s physiological, hormonal, and often fixable – if we treat sleep as a crucial component of our wellness and mood.
