Why linen bedding is good for your health

What’s so great about linen sheets?

To start with, linen is a natural material – which is where a lot of its selling points stem from.

“Linen is a superhero fabric. It’s crafted from the flax plant, which means it is completely natural and thus boasts a host of natural benefits that synthetics (and other manchesters) simply do not,” Bed Threads. co-founder Geneviève tells Body+Soul. “Linen is ultra-durable and yet still, only gets softer and more beautiful with time and use. Perhaps what makes it most attractive though are its natural temperature-regulating abilities.”

Sleep expert Olivia Arezzolo broke it down further to explain these abilities, and how they can improve your sleep quality.

“Linen is a thermoregulatory fabric – which essentially means it keeps you cool in summer, while providing warmth in winter. By absorbing excessive heat and moisture, this ensures that you maintain a cool core body temperature,” she tells Body+Soul. “Not only does this mean you don’t wake up in a sweaty mess, it also supports melatonin synthesis – the hormone to make you sleepy. If you overheat, you produce less, contributing to sleeping difficulties and nighttime wakings.”

And technical explanations aside, it also doesn’t hurt that linen just looks effortlessly chic in any room – so you can level up your aesthetic with just one purchase.

What are the benefits of linen sheets?

As Geneviève and Olivia explained, the temperature-regulating properties of linen do more than just stop you feeling sweaty – they can decrease stress and brain fog, increase happiness, and contribute to better skin and overall health too.

“In helping you keep a cool core body temperature and produce melatonin, you’re more likely to sleep deeper, and spend more time in slow wave sleep. This sleep phase helps with mental health: it reduces levels of cortisol, the stress hormone; and increases dopamine and serotonin, happiness hormones,” Olivia explains.

“Slow wave sleep is also necessary for mental clarity – it’s during this sleep phase that we have a clearance of beta amyloid, a neurotoxin to otherwise lead to memory loss. Finally, attaining sufficient slow wave sleep is also necessary for lean muscle mass maintenance (hello health goals) and collagen synthesis – both are dependent upon growth hormone, and 70 per cent of it is produced during this sleep phase.”

If all of that wasn’t enough, it turns out that linen bedding isn’t just better for you – it’s better for the planet, too.

“Linen bedding is environmentally-friendly (the entire flax plant is used when cultivated for everything from linen bedding to the flaxseeds you enjoy in your morning smoothie!), and as it’s all natural, means it’s biodegradable too,” explains Geneviève.

Are cotton or linen sheets better?

As someone who always thought that the ultimate bedding to aspire to is high-thread count cotton, I was confused when linen jumped onto the scene with its superior claims. So, I posed the question to Olivia: which material wins out?

“It’s a fallacy that high thread count equates to a better night sleep,” Olivia reveals. “In fact, anything above 400 thread count is not recommended – it’s too dense and can trap heat, exacerbate overheating and – as mentioned – lessen sleep quality.”

And that’s not where the revelations end – because it turns out that not all linen is created equal, and certain varieties provide greater benefits than others.

“At Bed Threads., we use pure, 100 per cent French Flax Linen exclusively—so, no blends—and strictly at a weight of 170GSM. This is the perfect weight for bedding—not too heavy for summer, but still weighty enough to keep you warm through the cooler seasons, so you don’t have to swap or upgrade your sheets constantly. We also use this weight for our loungewear range, so you can enjoy the softness and comfort enjoyed in bed when you have to eventually get out!” says Geneviève.

Are linen sheets good for summer or winter?

Linen is pretty much synonymous with summer: when the weather gets warm, we all don our linen dresses and shirts to get through the heat in style. Naturally then, linen bedding is ideal for summer.

“The weave of the flax fibres in linen is open, which ensures that air can flow freely through the fabric. This ensures that there’s always air circulating around your body to keep you cool if you’re prone to overheating. The moisture-wicking ability of linen is what makes it absorbent, able to keep your body cool when sweaty and drying quickly whenever wet. It’s this that makes linen perfect for the summer,” says Geneviève.

That said, it doesn’t mean you’ll only get use out of your linen sheets for one season – because they actually work year-round too.

“All the things that make linen great in warm weather work in cold weather, too,” Geneviève says. “That moisture-wicking quality ensures that even if you layer up the bed with sheets you won’t get sweaty while wrapped up in your duvet and blankets. Linen’s breathable and air-circulating qualities keeps things snug in bed on colder nights, acting as a natural temperature insulator, while never letting you get overheated.”

Are linen sheets worth it?

For Olivia, as a sleep expert, there’s no question about whether she’d recommend linen: “Yes!” she exclaims.

And for Geneviève, whose search for the perfect sheets led her to create Bed Threads. in the first place, the answer is similarly enthusiastic. She would recommend linen bedding to everyone, because “we all sleep, and the right bedding can optimise those all-important eight hours!”

“It’s perfect for sweaty sleepers (or those who share a bed with one!) and, thanks to the aforementioned temperature-regulating abilities, cold sleepers, too. It’s amazing that one duvet cover can offer two sleepers at the same time the perfect temperature to help them sleep well. This is the beauty of linen,” she says.

“Ultimately, everyone should have the option to create a beautiful home, enjoy gorgeous interiors and most importantly… have all the tools they need for a deep, uninterrupted sleep, night after night!”
