Do we need more sleep in winter?
You may crave more time tucked under the covers when colder months approach. And it's not just your imagination - your body may require more sleep during the winter. This natural inclination towards extended rest during the chilly season is deeply rooted in our biology and evolutionary history.
The changing seasons have a profound impact on your internal rhythms. Just as the natural world around you prepares for the winter by slowing down and conserving resources, your body may follow suit, adapting to the shorter days and longer nights by prioritising rest. This adaptation process is a complex interplay of hormones, circadian rhythms, and environmental factors that have evolved over thousands of years.
You can lean into this seasonal shift by adjusting your sleep schedule to accommodate your body's changing needs. For instance, you could go to bed a little earlier, allow yourself to sleep in when possible, and create a cosy sleep environment. Understanding and working with these natural rhythms rather than fighting against them can lead to more restful and rejuvenating sleep during the winter months.
Join us below to discover more about winter sleep shenanigans and how you can make the most of your rest during the coldest season of the year.
Why does winter make me want to sleep more?
Your body's natural drive to sleep more in the winter is from the interplay between your circadian rhythms, melatonin (sleep hormone) production, and energy conservation needs during the colder, darker months. This complex biological system responds to various environmental cues, particularly the reduced daylight hours and dropping temperatures characteristic of winter.
You might crave lie-ins and earlier bedtimes because your body needs more rest, even though your energy expenditure during the day is perfectly normal. This increased desire for sleep isn't necessarily a sign of laziness or poor health - it's your body's natural response to environmental changes that have been programmed into our DNA through generations of human evolution.
If this matches your situation, you're not alone - millions of people want to sleep more in the winter and less in summer. It's just the order of things. This pattern is observed across different cultures and geographical locations, suggesting it's a fundamental aspect of human biology rather than a cultural phenomenon.
Right. But is more sleep necessary in winter?
Your body may need to conserve more energy in winter; increasing your sleep duration can help you do it. However, you don't need to sleep more in winter to maintain your health - you'll do fine with an average sleep duration. The key lies in maintaining consistent, quality sleep rather than simply increasing the quantity of hours spent in bed.
If you have seasonal affective disorder - a mild form of depression that comes from low sunlight and shorter days - getting more sleep may help you manage it, although more sleep can also give you brain fog. So, there's a balance to be struck. It's essential to find the right amount of sleep that works for your individual needs and circumstances, taking into account factors such as your daily routine, work schedule, and overall health.
Are there any benefits to sleeping more in winter?
Sleeping more in winter has no health benefits unless you improve your typical sleep duration and quality. Simply spending more time in bed doesn't automatically translate to better rest or improved well-being. The focus should be on optimising your sleep quality rather than just extending your time under the duvet.
Getting better-quality sleep means getting more REM sleep, which can enhance memory consolidation, problem-solving abilities, and overall cognitive functioning. During REM sleep, your brain processes and stores information from the day, strengthens neural connections, and helps maintain emotional balance - all crucial functions for maintaining optimal mental health during the darker winter months.
Quality sleep is also crucial to your immunity, mental health, energy levels, and appetite, so it pays to sleep well in winter, but not necessarily 'more.' Good sleep hygiene practices become particularly important during this season when our bodies might be more susceptible to illness and mood fluctuations.
Tips to improve your sleep this winter
Limit blue light exposure
Avoid screens, phones, and other blue light-emitting devices close to bedtime, as they can disrupt your natural melatonin production. Use night and blue light filters on your devices, turn them off, or wear blue light-blocking glasses. This is particularly important during winter when our exposure to natural light is already limited, and our circadian rhythms might be more sensitive to artificial light sources.
Invest in a supportive mattress
If you wake up with persistent aches and pains or experience discomfort whilst lying in bed, your mattress is likely failing to provide adequate support for your unique sleep position or body weight. This discomfort can significantly impact your sleep quality and leave you feeling unrested, particularly during the winter months when proper rest becomes even more crucial.
The relationship between your body weight and mattress firmness is a critical factor in achieving optimal sleep comfort. The heavier you are, the firmer your mattress needs to be to prevent excessive sinking and maintain proper spinal alignment. Similarly, some sleep positions naturally require either a firmer or softer comfort layer to effectively reduce pressure points and provide targeted support to different areas of your body.
To help you make an informed decision about your mattress choice, here are some comprehensive guidelines based on your sleeping position and weight:
For combination sleepers who frequently change positions, a medium-firm mattress is generally the most versatile choice. However, if you weigh less than 180 lbs, you might find better comfort with a slightly softer mattress that allows for easier movement whilst still providing adequate support.
If you're a side sleeper weighing less than 180 lbs (approximately 82 kg), a medium mattress offers the ideal balance of support and cushioning. This firmness level allows your shoulders and hips to sink slightly whilst maintaining proper spinal alignment and reducing pressure points along your side.
Back sleepers weighing up to 220 lbs (approximately 100 kg) will find optimal support with a medium-firm mattress. This firmness level helps maintain the natural curve of your spine whilst providing enough give to cradle your lower back and prevent gaps between your body and the mattress surface.
Front sleepers, regardless of weight, should always opt for a firm mattress. This increased firmness prevents your hips from sinking too deeply, which could otherwise cause lower back strain and discomfort. A firm surface helps maintain a neutral spine position throughout the night.
Adjust your bedtime
As the winter days grow shorter, it's beneficial to gradually shift your bedtime earlier in the evenings. This adjustment helps align your sleep schedule with the natural changes in daylight and supports your body's seasonal rhythms.
Make it your goal to achieve between 7-9 hours of quality sleep each night to accommodate your body's increased sleep needs during the winter months. Don't be concerned about naturally waking up a bit earlier - this can actually help you make the most of the limited winter daylight.
If you find yourself struggling to adapt to an earlier bedtime, there are several relaxation techniques you can employ. Consider reading a book in soft lighting, listening to calming music or nature sounds, or enjoying a warm bath to help signal to your body that it's time to wind down. These activities can naturally promote sleepiness and make the transition to an earlier bedtime more manageable.
