Eye color is generally considered so static that iris scans are considered a reasonable security method. However, it can indeed change—mostly for reasons you won’t want, though:

Ringing the changes

Putting aside any wishes of being a manga protagonist with violet eyes, here are the self-changing options:

  • Aging in babies: babies are often born with lighter eyes, which can darken as melanocytes develop during the first few months of life. This is similar to how a small child’s blonde hair can often be much darker by the time puberty hits!
  • Aging in adults: eyes may continue to darken until adulthood, while aging into the elderly years can cause them to lighten due to conditions like arcus senilis
  • Horner’s syndrome: a nerve disorder that can cause the eyes to become lighter due to loss of pigment
  • Fuchs heterochromic iridocyclitis: an inflammation of the iris that leads to lighter eyes over time
  • Pigment dispersion syndrome: the iris rubs against eye fibers, leading to pigment loss and lighter eyes
  • Kayser-Fleischer rings: excess copper deposits on the cornea, often due to Wilson’s disease, causing larger-than-usual brown or grayish rings around the iris
  • Iris melanoma: a rare cancer that can darken the iris, often presenting as brown spots
  • Cancer treatments: chemotherapy for retinoblastoma in children can result in lighter eye color and heterochromia
  • Medications: prostaglandin-based glaucoma treatments can darken the iris, with up to 23% of patients seeing this effect
  • Vitiligo: an autoimmune disorder that destroys melanocytes, mostly noticed in the skin, but also causing patchy loss of pigment in the iris
  • Emotional and pupil size changes: emotions and trauma can affect pupil size, making eyes appear darker or lighter temporarily by altering how much of the iris is visible

For more about all these, and some notes about more voluntary changes (if you have certain kinds of eye surgery), enjoy:

  • If You’re Poor, Fertility Treatment Can Be Out of Reach

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Mary Delgado’s first pregnancy went according to plan, but when she tried to get pregnant again seven years later, nothing happened. After 10 months, Delgado, now 34, and her partner, Joaquin Rodriguez, went to see an OB-GYN. Tests showed she had endometriosis, which was interfering with conception. Delgado’s only option, the doctor said, was in vitro fertilization.

    “When she told me that, she broke me inside,” Delgado said, “because I knew it was so expensive.”

    Delgado, who lives in New York City, is enrolled in Medicaid, the federal-state health program for low-income and disabled people. The roughly $20,000 price tag for a round of IVF would be a financial stretch for lots of people, but for someone on Medicaid — for which the maximum annual income for a two-person household in New York is just over $26,000 — the treatment can be unattainable.

    Expansions of work-based insurance plans to cover fertility treatments, including free egg freezing and unlimited IVF cycles, are often touted by large companies as a boon for their employees. But people with lower incomes, often minorities, are more likely to be covered by Medicaid or skimpier commercial plans with no such coverage. That raises the question of whether medical assistance to create a family is only for the well-to-do or people with generous benefit packages.

    “In American health care, they don’t want the poor people to reproduce,” Delgado said. She was caring full-time for their son, who was born with a rare genetic disorder that required several surgeries before he was 5. Her partner, who works for a company that maintains the city’s yellow cabs, has an individual plan through the state insurance marketplace, but it does not include fertility coverage.

    Some medical experts whose patients have faced these issues say they can understand why people in Delgado’s situation think the system is stacked against them.

    “It feels a little like that,” said Elizabeth Ginsburg, a professor of obstetrics and gynecology at Harvard Medical School who is president-elect of the American Society for Reproductive Medicine, a research and advocacy group.

    Whether or not it’s intended, many say the inequity reflects poorly on the U.S.

    “This is really sort of standing out as a sore thumb in a nation that would like to claim that it cares for the less fortunate and it seeks to do anything it can for them,” said Eli Adashi, a professor of medical science at Brown University and former president of the Society for Reproductive Endocrinologists.

    Yet efforts to add coverage for fertility care to Medicaid face a lot of pushback, Ginsburg said.

    Over the years, Barbara Collura, president and CEO of the advocacy group Resolve: The National Infertility Association, has heard many explanations for why it doesn’t make sense to cover fertility treatment for Medicaid recipients. Legislators have asked, “If they can’t pay for fertility treatment, do they have any idea how much it costs to raise a child?” she said.

    “So right there, as a country we’re making judgments about who gets to have children,” Collura said.

    The legacy of the eugenics movement of the early 20th century, when states passed laws that permitted poor, nonwhite, and disabled people to be sterilized against their will, lingers as well.

    “As a reproductive justice person, I believe it’s a human right to have a child, and it’s a larger ethical issue to provide support,” said Regina Davis Moss, president and CEO of In Our Own Voice: National Black Women’s Reproductive Justice Agenda, an advocacy group.

    But such coverage decisions — especially when the health care safety net is involved — sometimes require difficult choices, because resources are limited.

    Even if state Medicaid programs wanted to cover fertility treatment, for instance, they would have to weigh the benefit against investing in other types of care, including maternity care, said Kate McEvoy, executive director of the National Association of Medicaid Directors. “There is a recognition about the primacy and urgency of maternity care,” she said.

    Medicaid pays for about 40% of births in the United States. And since 2022, 46 states and the District of Columbia have elected to extend Medicaid postpartum coverage to 12 months, up from 60 days.

    Fertility problems are relatively common, affecting roughly 10% of women and men of childbearing age, according to the National Institute of Child Health and Human Development.

    Traditionally, a couple is considered infertile if they’ve been trying to get pregnant unsuccessfully for 12 months. Last year, the ASRM broadened the definition of infertility to incorporate would-be parents beyond heterosexual couples, including people who can’t get pregnant for medical, sexual, or other reasons, as well as those who need medical interventions such as donor eggs or sperm to get pregnant.

    The World Health Organization defined infertility as a disease of the reproductive system characterized by failing to get pregnant after a year of unprotected intercourse. It terms the high cost of fertility treatment a major equity issue and has called for better policies and public financing to improve access.

    No matter how the condition is defined, private health plans often decline to cover fertility treatments because they don’t consider them “medically necessary.” Twenty states and Washington, D.C., have laws requiring health plans to provide some fertility coverage, but those laws vary greatly and apply only to companies whose plans are regulated by the state.

    In recent years, many companies have begun offering fertility treatment in a bid to recruit and retain top-notch talent. In 2023, 45% of companies with 500 or more workers covered IVF and/or drug therapy, according to the benefits consultant Mercer.

    But that doesn’t help people on Medicaid. Only two states’ Medicaid programs provide any fertility treatment: New York covers some oral ovulation-enhancing medications, and Illinois covers costs for fertility preservation, to freeze the eggs or sperm of people who need medical treatment that will likely make them infertile, such as for cancer. Several other states also are considering adding fertility preservation services.

    In Delgado’s case, Medicaid covered the tests to diagnose her endometriosis, but nothing more. She was searching the internet for fertility treatment options when she came upon a clinic group called CNY Fertility that seemed significantly less expensive than other clinics, and also offered in-house financing. Based in Syracuse, New York, the company has a handful of clinics in upstate New York cities and four other U.S. locations.

    Though Delgado and her partner had to travel more than 300 miles round trip to Albany for the procedures, the savings made it worthwhile. They were able do an entire IVF cycle, including medications, egg retrieval, genetic testing, and transferring the egg to her uterus, for $14,000. To pay for it, they took $7,000 of the cash they’d been saving to buy a home and financed the other half through the fertility clinic.

    She got pregnant on the first try, and their daughter, Emiliana, is now almost a year old.

    Delgado doesn’t resent people with more resources or better insurance coverage, but she wishes the system were more equitable.

    “I have a medical problem,” she said. “It’s not like I did IVF because I wanted to choose the gender.”

    One reason CNY is less expensive than other clinics is simply that the privately owned company chooses to charge less, said William Kiltz, its vice president of marketing and business development. Since the company’s beginning in 1997, it has become a large practice with a large volume of IVF cycles, which helps keep prices low.

    At this point, more than half its clients come from out of state, and many earn significantly less than a typical patient at another clinic. Twenty percent earn less than $50,000, and “we treat a good number who are on Medicaid,” Kiltz said.

    Now that their son, Joaquin, is settled in a good school, Delgado has started working for an agency that provides home health services. After putting in 30 hours a week for 90 days, she’ll be eligible for health insurance.

    One of the benefits: fertility coverage.

  • How to Permanently Loosen a Tight Psoas

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    What Is Your Psoas?

    Your psoas is a deep muscle in your lower back and hip area that connects your spine to your thigh bone. It helps you bend your hips and spine, making it a hip flexor.

    In today’s video, Your Wellness Nerd (the YouTube channel behind the video below) has revealed some great tips on loosening said tight hip flexors!

    How to loosen them

    First off, the big reveal…your tight psoas is likely stemming from an overlooked cause: your lower back! The video kicks off with a simple technique to loosen up that stiff area in your lower back. All you need is a foam roller.

    But, before diving into the exercises, it’s essential to gauge your current flexibility. A basic hip flexor stretch serves as a pre-test.

    Note: the goal here isn’t to stretch, but rather to feel how tight you are.

    After testing, it’s time to roll…literally. Working through the lower back, use your roller or tennis ball to any find stiff spots and loosen them out; those spots are likely increasing the tension on your psoas.

    After some rolling, retest with the hip flexor stretch. Chances are, you’ll feel more mobility and less tightness right away.

    Note: this video focuses on chronic psoas issues. If you have sore psoas from a muscular workout, you may want to read our piece on speeding up muscle recovery.

    Is That All?

    But wait, there’s more! The video also covers two more exercises specifically targeting the psoas. This one’s hard to describe, so we recommend watching the video. However, to provide an overview, you’re doing the “classic couch stretch”, but with a few alterations.

    Next, the tennis ball technique zeroes in on specific tight spots in the psoas. By lying on the ball and adjusting its position around the hip area, you can likely release some deeply held tension.

    Additionally, some of our readers advocate for acupuncture for psoas relief – we’ve done an acupuncture myth-busting article here for reference.

    Other Sources

    If you’re looking for some more in-depth guides on stretching your psoas, and your body in general, we’ve made a range of 1-minute summaries of books that specifically target stretching:

    The final takeaway? If you’re constantly battling tight psoas muscles despite trying different exercises and stretches, it might be time to look at your lower back and your daily habits. This video isn’t just a band-aid fix; it’s about addressing the root cause for long-term relief:

  • Unfuck Your Brain – by Dr. Faith Harper

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This book takes a trauma-informed care approach, which is relatively novel in the mental health field and it’s quickly becoming the industry standard because of its effectiveness.

    The basic premise of trauma-informed care is that you had a bad experience (possibly even more than one—what a thought!) and that things that remind you of that will tend to prompt reactivity from you in a way that probably isn’t healthy. By identifying each part of that process, we can then interrupt it, much like we might with CBT (the main difference being that CBT, for all its effectiveness, tends to assume that the things that are bothering you are not true, while TIC acknowledges that they might well be, and that especially historically, they probably were).

    A word of warning: if something that triggers a trauma-based reactivity response in you is people swearing, then this book will either cure you by exposure therapy or leave you a nervous wreck, because it’s not just the title; Dr. Harper barely gets through a sentence without swearing. It’s a lot, even by this (European) reviewer’s standards (we’re a lot more relaxed about swearing over here, than people tend to be in America).

    On the other hand, something that Dr. Harper excels at is actually explaining stuff very well. So while it sometimes seems like she’s “trying too hard” style-wise in terms of being “not like other therapists”, in her defence she’s nevertheless a very good writer; she knows her stuff, and knows how to communicate it clearly.

    Bottom line: if you don’t mind a writer who swears more than 99% of soldiers, then this book is an excellent how-to guide for self-administered trauma-informed care.

  • Want the health benefits of strength training but not keen on the gym? Try ‘exercise snacking’

    The science is clear: resistance training is crucial to ageing well. Lifting weights (or doing bodyweight exercises like lunges, squats or push-ups) can help you live independently for longer, make your bones stronger, reduce your risk of diseases such as diabetes, and may even improve your sleep and mental health.

    But not everyone loves the gym. Perhaps you feel you’re not a “gym person” and never will be, or you’re too old to start. Being a gym-goer can be expensive and time-consuming, and some people report feeling unwelcome or awkward at the gym.

    The good news is you don’t need the gym, or lots of free time, to get the health benefits resistance training can offer.

    You can try “exercise snacking” instead.

    What is exercise snacking?

    Exercise snacking involves doing multiple shorter bouts (as little as 20 seconds) of exercise throughout the day – often with minimal or no equipment. It’s OK to have several hours of rest between.

    You could do simple bodyweight exercises such as:

    • chair sit-to-stand (squats)
    • lunges
    • box step-ups
    • calf raises
    • push-ups.

    Exercise snacking like this can help improve muscle mass, strength and physical function.

    It’s OK to hold onto a nearby object for balance, if you need. And doing these exercises regularly will also improve your balance. That, in turn, reduces your risk of falls and fractures.

    OK I have done all those, now what?

    Great! You can also try using resistance bands or dumbbells to do the previously mentioned five exercises as well as some of the following exercises:

    When using resistance bands, make sure you hold them tightly and that they’re securely attached to an immovable object.

    Exercise snacking works well when you pair it with an activity you do often throughout the day. Perhaps you could:

    • do a few extra squats every time you get up from a bed or chair
    • do some lunges during a TV ad break
    • chuck in a few half squats while you’re waiting for your kettle to boil
    • do a couple of elevated push-ups (where you support your body with your hands on a chair or a bench while doing the push-up) before tucking into lunch
    • sneak in a couple of calf raises while you’re brushing your teeth.

    What does the evidence say about exercise snacking?

    One study had older adults without a history of resistance training do exercise snacks at home twice per day for four weeks.

    Each session involved five simple bodyweight exercises (chair sit-to-stand, seated knee extension, standing knee bends, marching on the spot, and standing calf raises). The participants did each exercise continuously for one minute, with a one-minute break between exercises.

    These short and simple exercise sessions, which lasted just nine minutes, were enough to improve a person’s ability to stand up from a chair by 31% after four weeks (compared to a control group who didn’t exercise). Leg power and thigh muscle size improved, too.

    Research involving one of us (Jackson Fyfe) has also shown older adults found “exercise snacking” feasible and enjoyable when done at home either once, twice, or three times per day for four weeks.

    Exercise snacking may be a more sustainable approach to improve muscle health in those who don’t want to – or can’t – lift heavier weights in a gym.

    A little can yield a lot

    We know from other research that the more you exercise, the more likely it is you will keep exercising in future.

    Very brief resistance training, albeit with heavier weights, may be more enjoyable than traditional approaches where people aim to do many, many sets.

    We also know brief-and-frequent exercise sessions can break up periods of sedentary behaviour (which usually means sitting too much). Too much sitting increases your risk of chronic diseases such as diabetes, whereas exercise snacking can help keep your blood sugar levels steady.

    Of course, longer-term studies are needed. But the evidence we do have suggests exercise snacking really helps.

    Why does any of this matter?

    As you age, you lose strength and mass in the muscles you use to walk, or stand up. Everyday tasks can become a struggle.

    All this contributes to disability, hospitalisation, chronic disease, and reliance on community and residential aged care support.

    By preserving your muscle mass and strength, you can:

    • reduce joint pain
    • get on with activities you enjoy
    • live independently in your own home
    • delay or even eliminate the need for expensive health care or residential aged care.

    What if I walk a lot – is that enough?

    Walking may maintain some level of lower body muscle mass, but it won’t preserve your upper body muscles.

    If you find it difficult to get out of a chair, or can only walk short distances without getting out of breath, resistance training is the best way to regain some of the independence and function you’ve lost.

    It’s even more important for women, as muscle mass and strength are typically lower in older women than men. And if you’ve been diagnosed with osteoporosis, which is more common in older women than men, resistance exercise snacking at home can improve your balance, strength, and bone mineral density. All of this reduces the risk of falls and fractures.

    You don’t need heavy weights or fancy equipment to benefit from resistance training.

    So, will you start exercise snacking today?

  • ‘Disease X’: What it is (and isn’t)

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    What you need to know

    • In January 2024, the World Economic Forum hosted an event called Preparing for Disease X to discuss strategies to improve international pandemic response.
    • Disease X is a term used in epidemiology to refer to potential disease threats. It is not a real disease or a global conspiracy.
    • Preparation to prevent and respond to future pandemics is a necessary part of global health to keep us all safer.

    During the World Economic Forum’s 54th annual meeting in Davos, Switzerland, global health experts discussed ways to strengthen health care systems in preparation for future pandemics. Conspiracy theories quickly began circulating posts about the event and the fictional disease at its center, so-called Disease X. 

    What is Disease X?

    In 2018, the World Health Organization added Disease X to its list of Blueprint Priority Diseases that are public health risks. But, unlike the other diseases on the list, Disease X doesn’t exist. The term represents a hypothetical human disease capable of causing a pandemic. Although experts don’t know what the next Disease X will be, they can make educated guesses about where and how it may emerge—and how we can prepare for it.

    Why are we hearing about Disease X now?

    COVID-19 has been the deadliest infectious disease outbreak of the 21st century. It’s also an example of a Disease X: a previously unknown pathogen that spreads rapidly around the world, claiming millions of lives. 

    When the WEF hosted a panel of experts to discuss Disease X, it was the first exposure that many people had to a concept that global health experts have been discussing since 2018.

    Even before the routine pandemic preparedness event took place, online conspiracy theorists began circulating false claims that those discussing and preparing for Disease X had sinister motives, underscoring how widespread distrust of global health entities has become in the wake of the COVID-19 pandemic. 

    Why does Disease X matter?

    Epidemiologists use concepts like Disease X to plan for future outbreaks and avoid the mistakes of past outbreaks. The COVID-19 pandemic and the recent non-endemic outbreak of mpox highlight the importance of global coordination to efficiently prevent and respond to disease outbreaks.

    Pandemics are inevitable, but the scale of their destruction doesn’t have to be. Major disease outbreaks are likely to become more frequent due to the impacts of climate change. Preparing for a pandemic now helps ensure that the world is better equipped to handle the next one.

  • Beat Osteoporosis with Exercise – by Dr. Karl Knopf

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    There are a lot of books about beating osteoporosis, and yet when it comes to osteoporosis exercises, it took us some work to find a good one. But, this one’s it!

    A lot of books give general principles and a few sample exercises. This one, in contrast, gives:

    • An overview of osteopenia and osteoporosis, first
    • A brief overview of non-exercise osteoporosis considerations
    • Principles for exercising a) to reduce one’s risk of osteoporosis b) if one has osteoporosis
    • Clear explanations of about 150 exercises that fit both categories

    This last item’s important, because a lot of popular advice is exercises that are only good for one or the other (given that a lot of things that strengthen a healthy person’s bones can break the bones of someone with osteoporosis), so having 150 exercises that are safe and effective in both cases, is a real boon.

    That doesn’t mean you have to do all 150! If you want to, great. But even just picking and choosing and putting together a little program is good.

    Bottom line: if you’d like a comprehensive guide to exercise to keep you strong in the face of osteoporosis, this is a great one.
