Best Period Underwear for 2025
I first tested all of the above underwear for fit, to determine if they are true to size. That mostly involved a lot of trying them on, wearing them under pants to see how bulky or slim they were and if you could see panty lines.
Next, I tested the absorbency to see if it lived up to the claims. Since it would take me well over a year to test each one of them while on my period, I developed an easily repeatable method in my home lab (also called the kitchen).
I washed each pair of underwear according to the label and air dried. You'll want to wash your period underwear before you wear them for the first time to remove any starch or other chemicals used in the manufacturing process. Air drying is important to preserving the underwear's absorbency -- fabric softener or dryer sheets can leave behind a film that doesn't allow moisture to pass through.
Next, for every pair, I checked how many tampons' worth of fluid they can hold and converted that amount into millimeters. This is not exact because there's some variation in tampons across brands, but in general, one regular tampon can hold 5ml of liquid.
I slowly poured that amount of water over the gusset of the underwear to see how quickly it absorbed and if any water leaked. I left them for 30 minutes and then checked to see how dry they were after absorbing the water. Some were just as wet as when I started the test, others were dry enough to comfortably keep wearing.
I will caveat that this is not a perfect test. Menstrual fluid usually leaves your body slowly over the course of a few hours, though some people experience short gushes throughout the day. Some of the underwear I tested didn't absorb the entire amount of water right away and/or leaked, but that doesn't mean they wouldn't work for your period. If your flow is steady over the course of a day, period underwear will have time to absorb it slowly, which will minimize leaks.
If you pass multiple clots during your period or experience repeated gushing/flooding, period underwear might struggle to absorb fluid and keep you feeling dry.

NIAID acting director's view of ‘risky research'
THE LAB Dr. Jeffery Taubenberger, acting director of the National Institute of Allergy and Infectious Diseases, says conducting so-called gain-of-function research shouldn't be dismissed. He discussed the controversial topic with his boss, NIH Director Jay Bhattacharya, on the latter's 'Director's Desk' podcast this week. What is it? Gain-of-function involves genetically altering pathogens to make them deadlier or more transmissible to better study them. But the research is a lightning rod issue for President Donald Trump and many Republicans in Congress who believe the Covid-19 pandemic was caused by a lab leak stemming from gain-of-function research in Wuhan, China, where the virus first emerged. That thinking puts them at odds with most of the scientific community who believe the virus most likely spilled over from animals into humans. In May, Trump signed an executive order banning all 'present and all future' federal funding for gain-of-function research in countries like China,which Trump said has insufficient research oversight. He also ordered the National Institutes of Health to review and possibly halt experiments the administration believes could endanger Americans' lives. In Congress, Sen. Rand Paul's (R-Ky.) Risky Research Review Act, which hasn't yet been taken up by the full Senate, would create a panel to review funding for gain-of-function research. Not black and white: During the podcast, Bhattacharya asked Taubenberger how the institute should approach gain-of-function research. 'It's not a simple black-and-white issue,' replied Taubenberger, a senior investigator in virology who's a leading expert on the 1918 flu pandemic and sequenced the virus that caused it. He's also co-leading the effort to develop a universal flu vaccine, backed with $500 million from the Trump administration. 'Very reasonable, very well-informed people could fall on opposite sides of the line, wherever you draw the line,' he said. 'Having a wide variety of people with different levels of expertise — not just logic expertise, but safety, national security, all sorts of other questions — having them weigh in on this is really important.' Regardless of where people fall, gain-of-function work shouldn't be shut down, he said. 'Work on nasty bugs that have the potential to kill people, for which we want to develop better therapeutics, diagnostics, prognostics, treatments and preventatives, needs to happen. That's important for global health. It's important for U.S. health,' Taubenberger said. But that research has to be done very carefully, with oversight and should be evaluated on a risk-benefit basis, he warned. While the pandemic turbocharged the issue, the controversy over gain-of-function predates Covid-19. The government paused funding for the research roughly a decade ago, Taubenberger pointed out, while they put stronger oversight mechanisms in place. 'I favor this kind of work being done, where possible, in U.S. government labs, by U.S. government scientists, monitored by U.S. government safety officials and regulators — with openness and transparency.' What didn't come up in conversation: The implementation of Trump's executive order hasn't gone as smoothly as the podcast discussion might have suggested. A July post on the NIH's X account implied that staff at the NIAID had acted inappropriately by omitting certain grants while compiling a list of potentially dangerous gain-of-function research experiments in compliance with the order. Contacted by POLITICO at the time, an official at HHS described the behavior as 'malicious compliance' and said the administration wouldn't tolerate it. NIH Principal Deputy Director Matt Memoli, according to The Washington Post, overrode staff by classifying tuberculosis studies NIH reviewers deemed safe as potentially dangerous gain-of-function research.

TECH MAZE Under Gov. Gavin Newsom, California has moved faster than other states to regulate artificial intelligence, including signing a bill last year barring health insurers in the state from using AI to deny claims. Now, a prominent AI company is urging the Democratic governor to consider a less rigid regulatory approach. In a letter to Newsom, obtained by our POLITICO colleagues at California Decoded, OpenAI suggests that California should consider AI companies that sign onto national and international AI agreements as compliant with state AI rules. The letter, dated Monday, from OpenAI's Chief Global Affairs Officer Chris Lehane, comes as Sacramento continues to debate key AI legislation, including Democratic state Sen. Scott Wiener's bill SB 53, which would require large AI developers to publish safety and security protocols on their websites. Lehane recommended that 'California take the lead in harmonizing state-based AI regulation with emerging global standards' when it comes to the technology, dubbing it the California Approach. World view: OpenAI and other developers have already signed, or plan to sign, onto the EU's AI code of practice and have committed to conducting national security-related assessments of their programs. Lehane said that 'we encourage the state to consider frontier model developers compliant with its state requirements when they sign onto a parallel regulatory framework like the [European Union's] CoP or enter into a safety-oriented agreement with a relevant US federal government agency.' Newsom spokesperson Tara Gallegos said, 'We have received the letter. We don't typically comment on pending legislation.' Worth noting: The EU code is a voluntary way for companies to comply with the bloc's AI Act and is nonbinding in the U.S., which has no equivalent. Commitments to work with federal regulators don't necessarily cover all the areas, like deepfakes or chatbots, where Sacramento wants to regulate AI. But the letter offers Newsom something of an off-ramp, after he vetoed Wiener's broader AI safety bill last year that would have required programs to complete prerelease safety testing. Last week, Newsom spoke with cautious positivity about Wiener's effort this year, saying it was in the spirit of an expert report on AI regulation he commissioned. But SB 53 — which would establish whistleblower protections for AI workers and require companies to publish their own internal safety testing — still faces opposition from the tech industry. Lehane's letter puts an industry-sponsored solution on the governor's desk. He framed the simplified California Approach as a way to give 'democratic AI' an edge in the race with Chinese-built programs by removing unnecessary regulation, a key priority for the Trump administration. 'Imagine how hard it would have been during the Space Race had California's aerospace and technology industries been encumbered by regulations that impeded rapid innovation,' Lehane wrote.

If You Haven't Washed Your Sheets Lately, You're Sleeping With Millions of Bacteria
There's something satisfying about climbing into bed after a long day. The mattress matters, and so does the comforter, but clean sheets can make or break that cozy feeling. If it has been a while since you last changed them, you might not be curling up in just fabric. Sheets quietly collect things you would probably rather not think about - sweat, skin cells, body oils, and dust mites. All of that can add up and start to bother your skin or make sleep less restful. So, how often should you actually wash them? Most sleep experts suggest about once a week, though some people might need to do it a little more or less often depending on their routines. If you are unsure where to start or want to make the process faster, a few small adjustments can help. These tips walk you through washing sheets the right way so your bed feels fresh and your sleep space stays healthy. How often should I change or wash my sheets? The common rule of thumb is to wash sheets every other week. Ideally, sleep experts recommend changing sheets every week but agree that every two weeks is the absolute longest one should go sleeping on the same set of sheets. When to wash all bedding Bedding type Frequency Sheets Once a week or every other week Pillowcases Once a week or every other week Duvet covers Once a week or every other week Comforters Once a month or every other month (or more frequently if you sleep with pets) Duvet inserts Once or twice a year Mattress pads Every three to four months Why do we wash our sheets and bedding? Hygiene is always important, even with our bedding. If you can't see stains or smell any odor, it doesn't mean your sheets are clean. Sheets can accumulate dead skin, mites, animal dander, pollen, makeup, bodily secretions and more grime, which may cause discomfort or skin rashes. One of the biggest reasons to regularly clean sheets is because of sweat. In a May study, 41% of participants reported experiencing night sweats in a month and generally, people tend to run hot when covered in blankets or living in warmer climates. Sweat can soak into the sheets which can clog up the fibers and make the sheets smell. You should wash your sheets more often if you tend to sleep with your pet. Elena Grigorovich/EyeEm/Getty Images You should also wash your sheets more often if: You have allergies or asthma You have sensitive skin You sweat or overheat frequently You sleep naked You sleep with a pet You eat in bed You get in bed before showering You lay in bed wearing clothes you wore out in public You have an infection or open wound that touches the bedding What's the best way to machine-wash my sheets? Most bedsheets are machine washable and aren't much of a hassle to clean. Cotton and linen bedsheets are especially easy, while silk and satin are a bit more temperamental, requiring cold temperatures and slow spin cycles. It's best to always check the care tag on your sheets but this is the best method to machine-wash the majority of sheet sets: 1. Don't overwhelm the machine It can be tempting to just throw every pillowcase, fitted sheet and comforter right into the machine but throwing everything in at once may be too much and you may not get a good clean. I recommend washing the fitted and flat sheets together with your pillowcases and then washing any heavier comforter, quilt or throw blanket separately. Definitely don't throw in any clothing or towels with your bedding because it could leach color or have buttons and zippers that will damage delicate sheets. Bulkier items like duvet covers should be washed alone. iso_petrov/Getty Images 2. Check the label I always recommend checking the care label for the ideal washing temperature because some fabrics can shrink in the wash. It's best to use the hottest temperature the sheets can tolerate because hot water most effectively kills germs and bacteria. Colder cycles may not fully get rid of the grime. Polyester blends are best in warm water, while cotton can tolerate hot water. Silk and satin sheets should be washed on a cold, gentle cycle. 3. Separate by color Separate your sheets by color to preserve the colors and prevent dye from transferring. This means that you should make sure to put light-colored and dark-colored sheets together before washing. 4. Check bedsheets for stains Stains are better when cared for pre-wash, so take a few minutes to examine your sheets or pillowcases for stubborn blemishes. You can use a gentle dish soap and water, or baking soda and water mixture to let sit for a few minutes if you spot a dark mark or makeup stain. 5. Measure out detergent Less is usually more when using detergent. Too much detergent can lead to the machine using excess water or cause buildup in the washing machine's pipes. Most detergents are acceptable to use on cotton and linen sheets but choose a detergent for delicate fabrics to wash silk and satin sheets. There are many silk or satin-friendly detergents on the market. A good rule of thumb is to use 2 ounces (1/4 cup) or half a cap full of liquid laundry detergent for a regular-sized load of bedding. You can also use 4 ounces (1/2 cup) or 1 full cap of liquid laundry detergent for a larger load of bulkier items. I also recommend skipping the fabric softener because it can weaken the fabric. 6. Dry completely For most sheets, you can use the dryer on low to medium heat. Satin and silk sheets would do best to air dry because they can be easily damaged even on a low-heat dryer cycle. You can also throw in a few dryer balls with your bedding because they allow gaps, helping the bulkier sheets to dry more quickly and evenly (I always hate when I think I'm finally ready to make my bed and I realize one whole section is still damp from being bundled up). You can avoid cleaning your bedsheets as often by making it a habit to not eat in bed, not sleeping with your pet and only cuddling down in the sheets after a shower. It may seem like a hassle to strip your bed every week but it's well worth the extra effort, so you can sleep and relax a little easier. For more hacks, check out how to remove makeup stains from bedding and our sleep experts' favorite bed material. Can you wash sheets and clothes together? While you can wash sheets and clothes together, many experts recommend washing them separately to prevent clothes from getting caught in the sheets and not being washed thoroughly. Sheets may also have different washing instructions from clothes so washing them separately can help preserve the different fabrics and prevent damage. Does making your bed keep the sheets clean longer? Making the bed is an important part of many people's morning routine, and can make your room appear cleaner and more put together, but it won't necessarily extend the freshness of your sheets. In fact, letting your sheets air out for awhile after you wake up can actually keep them cleaner, especially if you tend to sweat at night. When you immediately pull your comforter or duvet over your sheets in the morning, it can restrict airflow and trap any moisture or odors that've built up throughout the night. This can create a warm, damp environment that is ideal for dust mites and bacteria growth. Instead, many experts recommend letting your sheets air out in the morning before making the bed. Try pulling your duvet down and letting them breathe for a bit while you go about your morning routine. Then, you can circle back and make the bed before you leave the house, if desired. Though you should still be washing your bedsheets regularly regardless of whether you make the bed daily. More cleaning and laundry tips

Best Period Underwear for 2025
I'm no stranger to period underwear and other "alternative" period products (where my menstrual cup fans at?), so I jumped at the chance to write this guide. When you're on your period, staying dry and comfortable are the top priorities, so I judged every pair of these underwear through that lens. I first tested all of the above underwear for fit, to determine if they are true to size. That mostly involved a lot of trying them on, wearing them under pants to see how bulky or slim they were and if you could see panty lines. Next, I tested the absorbency to see if it lived up to the claims. Since it would take me well over a year to test each one of them while on my period, I developed an easily repeatable method in my home lab (also called the kitchen). I washed each pair of underwear according to the label and air dried. You'll want to wash your period underwear before you wear them for the first time to remove any starch or other chemicals used in the manufacturing process. Air drying is important to preserving the underwear's absorbency -- fabric softener or dryer sheets can leave behind a film that doesn't allow moisture to pass through.
