The primary downsides of microfiber sheets are their lack of breathability, static generation, and tendency to trap heat. Because they are made from tightly woven synthetic materials (like polyester) rather than natural fibers, they can cause you to overheat and sweat at night.
Microfiber bedding is not inherently toxic or dangerous, but it is synthetic (made of plastic), which makes it less than ideal for some sleepers.
The healthiest sheets are made from natural, breathable fibers processed without toxic dyes, bleaches, or synthetic finishes. The best options—GOTS-certified organic cotton, bamboo viscose, and Eucalyptus Lyocell—minimize chemical exposure, regulate temperature, and prevent skin irritation.
Linen, made from the flax plant, is another excellent option for people with RLS. It's highly breathable and moisture-wicking, helping to maintain a steady temperature throughout the night. Linen's airy weave prevents overheating while keeping you comfortably warm during cooler months.
Cotton sheets are a breathable, natural fabric that gets softer with every wash, making them ideal for hot sleepers and warm climates. Microfiber sheets are made of finely woven synthetic materials that provide a silky, budget-friendly feel and excellent durability, but they tend to trap heat.
Hotels look for a fiber and natural materials that are durable, easy to care for, and comfortable. Overwhelmingly the common types of fibers 5-star hotels will choose are cotton or a blend of cotton and polyester. Types of cotton include USA, Supima cotton, Pima cotton, Upland cotton and a wide range of others.
Microfiber Sheets
They should be washed every 1-2 weeks, just like cotton and bamboo sheets. However, microfiber tends to attract dust and pet hair more than natural fabrics, so if you have pets or allergies, you may need to wash your sheets more frequently.
Martha Stewart recently went on the In Bed with Paige DeSorbo Amazon livestream and dropped a hot take about how often she swaps her bedding. Stewart revealed that she has her sheets changed every two to three days.
Yellow sheets on your boyfriend's side of the bed are completely normal and usually come down to biology. Men naturally have more active sweat and oil glands and higher testosterone levels than women, which leads to body oils and sweat oxidizing in the fabric.
Hospitals phased out traditional linen (flax-based) sheets in favor of synthetic blends and disposable paper options to meet the rigorous demands of modern healthcare.
Body Oil Transfer
Sebum naturally produced by your skin transfers to sheets every night. As these oils oxidize, they leave yellow stains and tinting, especially on cotton materials.
Five-star hotels typically use 100% long-staple cotton or high-quality cotton-polyester blends in a crisp percale or silky sateen weave. These luxury sheets feature true thread counts of 250 to 500, prioritizing durability and breathability through industrial laundering over artificially high thread counts.
Egyptian cotton is stronger than regular cotton, therefore longer-lasting. It's partly thanks to the extra-long fibres that Egyptian cotton plants produce, making yarns tougher yet oh so soft.
Here are a few of the top choices:
Cotton sheets are breathable, soft, hypoallergenic, and eco-friendly but cost more, wrinkle easily, and require careful care. Microfiber sheets are silky, durable, affordable, and low-maintenance, though they're less breathable, can trap heat, and aren't as eco-friendly.
It is not technically bad to sleep on polyester sheets, but you may not get the quality of sleep you are looking for. Polyester sheets can also cause or worsen rashes, itching, redness, eczema and dermatitis.
Hotels maintain perfectly white bedding by using industrial-grade machines, rigorous pre-treatment processes, and a carefully timed combination of commercial detergents, bleach, and bluing agents. Because all-white sheets are an industry standard, hotels rely on this scientific laundering approach to prevent yellowing and instantly discard any linens that show permanent discoloration.
Over time, natural body oils, sweat, and skin contact cause discoloration, especially if the same spot is used every night. Regular washing, breathable sheets, and protective covers can help keep things fresh and bright.
Nothing can be more irksome than removing underarm perspiration and yellow stains on clothes or removing mildew stains. White vinegar helps you there! Simply adding a cup of distilled white vinegar when giving the final rinse to the clothes will leave the cloth clean, fresh, and soft.
Most people should wash their sheets once per week. If you don't sleep on your mattress every day, you may be able to stretch this to once every two weeks or so. Some people should wash their sheets even more often than once a week.
Oprah Winfrey
Winfrey told the Hollywood Reporter in 2017 that she's usually in bed by 10 p.m. and wakes up naturally around 6 a.m. And, in typical Winfrey-fashion, her night-time routine includes a little self-reflection.
Martha Stewart is famously a massive fragrance enthusiast with a collection of over 70 perfumes. However, she has consistently sworn by one specific signature scent for decades, while also recently endorsing a popular gourmand fragrance.
Yes, but only in small amounts for hand washing. Dawn is excellent at breaking down grease and dirt, but it creates a massive amount of suds. Using it in a washing machine can cause soap overflows.
Ultimately, the decision comes down to personal preference, what you're used to, and how often you're willing to wash your bedding—some find it easier to just toss their entire sheet set into the wash rather than having to re-stuff their duvet back into its cover.
If you properly allow your sheets to dry out in the morning, then bacteria will grow for roughly two weeks, with a peak amount on your sheets at around the 14-day mark, says Petro. “So scientifically speaking, 14 days is probably when you're going to want to change your sheets,” he says.
