If you’ve scrolled through social media lately, you’ve probably noticed the viral ‘bedtime sock’ trend.
People claim putting on a pair of cozy socks before turning the lights out can help you fall asleep in minutes.
It almost sounds too easy – could something sitting in your dresser really work better than counting sheep or reaching for an over-the-counter sleep aid?
Social media is packed with quick health fixes, but this one actually has some science behind it.
To separate the buzz from the facts, Daily Mail spoke with Dr Fariha Abbasi-Feinberg, president of the American Academy of Sleep Medicine and director of sleep medicine at Millennium Physician Group in Fort Myers, Florida.
Here’s what wearing socks to bed may actually do, who might get the most out of it and how it stacks up against popular sleep solutions and remedies.
Warm Toes, Cool Core: The Science Behind Cozy Feet
Warm socks helping your body cool down sounds strange, right? But there’s a twist in the logic.
Your body’s internal thermostat uses a process called vasodilation. According to the Cleveland Clinic, as bedtime rolls around, your brain starts shifting heat away from your core and out toward your hands and feet. Warm feet open up blood vessels near the skin, helping heat escape.
For most adults, bedtime socks are an easy thing to try to improve sleep, especially if your toes are always freezing or you like a chilly bedroom
‘As we prepare for sleep, our bodies naturally redistribute heat from the core toward the hands and feet. Warming the feet can promote vasodilation, or widening of the blood vessels near the skin, which increases blood flow to the extremities and facilitates heat loss,’ explained Abbasi-Feinberg.
This process is associated with the natural decline in core body temperature that occurs around sleep onset and may help signal to the body that it is time to sleep, she added.
‘It is important to distinguish between supporting this natural heat-loss process and saying that socks themselves directly lower core body temperature,’ she continued
So, Do Bedtime Socks Really Help You Fall Asleep Faster?
The big claim making the rounds online is that wearing socks to bed can help restless sleepers nod off about 15 minutes faster.
Clinical research in the Journal of Clinical Anthropology does show an improvement in sleep onset latency, the amount of time it takes to go from fully awake to asleep, when your feet are kept comfortably warm.
Still, sleep specialists say not to take viral numbers at face value, plus it matters how the studies were done and who took part.
‘There is some evidence that warming the feet may help people fall asleep faster. However, it is important to put those findings into context… so we cannot assume everyone will experience the same benefit,’ Abbasi-Feinberg told Daily Mail.
‘More research in larger and more diverse populations is needed before we can make a universal recommendation.’
Who Might Benefit Most – and When Cold Feet Are More Than Just Annoying
For most adults, bedtime socks are an easy thing to try, especially if your toes are always freezing or you like a chilly bedroom. Warm feet may help your body relax and drift off. But if your feet are cold all the time, don’t just pile on thicker socks. It could be a sign of a medical issue worth getting checked out.
‘People who tend to have cold feet at bedtime or who sleep in a cooler environment may find wearing socks particularly comfortable and potentially helpful for falling asleep,’ she said. ‘Keeping the feet comfortably warm may support the body’s natural thermoregulatory processes as it prepares for sleep.’
However, persistently cold feet should be discussed with your healthcare provider.
‘If cold feet are frequent or severe, or are accompanied by symptoms such as pain, numbness, tingling, changes in skin color or sores that are slow to heal, it is important to discuss those symptoms with a healthcare professional.
‘In those circumstances, cold feet could be related to an underlying medical or circulatory condition that warrants evaluation,’ Abbasi-Feinberg said.
The most important considerations for choosing bedtime socks are comfort, breathability and fit
What Kind of Socks Work Best for Bed
Trying it tonight? Skip tight compression or athletic socks as they can squeeze your ankles and restrict circulation. Heavy synthetics can also leave your feet hot and sweaty, which may wake you up.
Abbasi-Feinberg recommends keeping your choice simple.
‘The most important considerations are comfort, breathability and fit,’ she said. ‘Choose clean, loose-fitting socks that keep the feet comfortably warm without being tight around the ankles or calves.
‘Breathable or moisture-wicking materials may also help prevent the feet from becoming excessively hot or sweaty. There is no need to purchase a special type of “sleep sock,’ and the American Academy of Sleep Medicine does not endorse specific sock products, materials or brands.’
Socks vs. Supplements
When it comes to socks versus supplements, Abbasi-Feinberg says it’s not really an apples-to-apples comparison.
‘Wearing socks is very different from taking a sleep medication or dietary supplement,’ she told Daily Mail.
‘Wearing socks is a simple, low-risk comfort measure that may support the body’s natural thermoregulation around bedtime. For someone whose cold feet make it difficult to get comfortable at night, it may be worth trying.’
The Bottom Line
Curious about bedtime socks? Give them a try with a clean, loose, breathable pair.
It’s an easy, inexpensive way to get comfortable while giving your body’s natural wind-down process a little help.
Just don’t expect socks to solve an ongoing sleep problem such as chronic insomnia.
If poor sleep keeps showing up and starts affecting how you feel or function during the day, talk with a healthcare professional rather than relying on quick fixes alone.
‘The overall goal is to create a comfortable sleep environment that is quiet, dark and cool,’ Abbasi-Feinberg said.
‘For people who experience persistent insomnia, the answer is not simply choosing between socks and a supplement. Chronic insomnia is a sleep disorder that deserves appropriate evaluation and treatment.’
