Sleeping Naked: Is It Better? Here’s What Happens When You Ditch the Pyjamas

In this article:

Let’s talk about something you might not usually bring up over dinner: sleeping naked.

Some people love their cosy pyjamas. Others prefer an oversized tee. But more and more people are asking: is it better to sleep naked? And science seems to say… yes, it might be!

Turns out, ditching the nightwear isn’t just about comfort — there are actual benefits of sleeping naked that can affect everything from your mood to your metabolism. Let’s break it down.

1. You’ll Sleep More Comfortably (and More Deeply)

Sleeping naked helps your body regulate its temperature naturally, which is super important for falling — and staying — asleep.

Your body’s internal clock, also called your circadian rhythm, relies on a slight drop in body temperature to signal that it’s time to sleep. Without extra layers of clothing trapping heat, your body can cool down faster and more effectively.

💡 Pro tip: The best bedroom temperature for sleep is around 60–67°F (15–19°C). Combine that with some breathable bedding and you’re good to go.

2. It May Help Small Wounds Heal Faster

This one’s a bit unexpected: research has shown that poor sleep can slow down your skin’s ability to heal from small cuts or wounds.

By improving your sleep quality — even by sleeping naked — you’re giving your body a better shot at repairing itself overnight. So your skin thanks you, too.

3. It Could Lower Your Risk of Disease

Let’s get serious for a second. Studies have linked poor sleep to a higher risk of things like diabetes, heart disease, and even Alzheimer’s. And better sleep = lower risk.

Your brain also uses deep sleep to clean itself — literally. It clears away toxic proteins that build up during the day. So when you sleep well (and perhaps naked), you’re helping your brain stay in top shape.

4. It’s Good for Your Sexual and Reproductive Health

Here’s where it gets even more interesting.

For men, keeping things cooler down there can actually boost fertility. One study found that guys who wore looser underwear had a 25% higher sperm count than those in tight briefs. And if boxers help — imagine what sleeping naked can do.

For both men and women, sleeping naked also allows the genitals to breathe, reducing the risk of bacterial or yeast infections.

And if you share your bed with a partner? Skin-to-skin contact while sleeping can release oxytocin, the "feel-good" hormone that supports intimacy, bonding and reduces stress. Win-win.

5. You Might Cut Down on Late-Night Cravings

Lack of sleep raises your cortisol levels — that’s the stress hormone. And when cortisol spikes, cravings often follow.

Less sleep = more desire for crisps, sweets, or whatever snack is whispering your name at 10pm. Getting better sleep (yes, even by sleeping naked) helps regulate hormones that control hunger.

One study even found that people who slept less than 5 hours a night were more likely to gain weight over time. So if you're looking to support your metabolism, your bedtime wardrobe — or lack thereof — might play a part.

6. It Helps You Chill Out (Literally and Mentally)

We all know a rough night’s sleep can make you feel frazzled, emotional, or just not quite yourself.

Sleeping naked can help your body cool down faster, easing you into that all-important REM sleep — the deep kind that supports memory, focus, and mood.

Poor sleep is linked to stress, anxiety, and even depression. So anything you can do to sleep better (including ditching the PJs) is worth considering.

7. It Can Boost Your Confidence

This one’s more about how you feel in your own skin. Some studies suggest that spending time in the nude — even just in bed — can help with body image and self-esteem.

The more comfortable you are with yourself, the more confident you’ll feel. And let’s be honest: confidence is attractive.

So… Is It Better to Sleep Naked?

We’d say give it a go. The benefits of sleeping naked range from physical to emotional to relationship perks. And it’s completely free.

Of course, what matters most is that you feel comfortable. Whether you wear PJs, a hoodie, or nothing at all — the goal is restful, restorative sleep.

But if you’re curious about the hype, why not try it for a night or two? You might just sleep cooler, deeper, and wake up feeling better all round.
