Genital herpes is on the rise. Here’s what to know about this common infection

The World Health Organization (WHO) recently released new estimates suggesting around 846 million people aged between 15 and 49 live with a genital herpes infection.

That’s equivalent to one in every five people from that age group.

At least one person each second (42 million people annually) contracts a new genital herpes infection.

So what is genital herpes, and are cases on the rise? Here’s what to know about this common infection.

First, what causes genital herpes?

Genital herpes is a sexually transmitted infection (STI) caused by the herpes simplex virus, which also causes cold sores.

There are two types of herpes simplex virus, HSV-1 and HSV-2 (and it’s possible to be infected by both at the same time).

HSV-1 most commonly spreads through oral contact such as kissing or sharing infected objects such as lip balm, cups or utensils, and presents as cold sores (or oral herpes) around the mouth. But it can also be sexually transmitted to cause a genital herpes infection.

An estimated 3.8 billion people under the age of 50 (64%) globally have HSV-1.

HSV-2 is less prevalent, but almost always causes a genital herpes infection. Some 520 million people aged 15–49 (13%) worldwide are believed to have HSV-2.

The initial episode of genital herpes can be quite painful, with blisters, ulcers and peeling skin around the genitals over 7–10 days.

Not all people have severe (or any) initial symptoms. This means a person might not know they have been infected with a herpes virus.

Herpes is a lifelong infection, which means once you contract the virus, you have it forever. After an initial episode, subsequent episodes can occur, but are usually less painful or even symptom free.

Both oral and genital herpes are particularly easy to spread when you have active lesions (cold sores or genital ulcers). But even with no symptoms, herpes can still be spread to a partner.

And although relatively rare, oral herpes can be transmitted to the genital area, and genital herpes can be transmitted to the mouth through oral sex.

If an expectant mother exhibits a genital herpes infection close to childbirth, there are risks to the baby. A herpes infection can be very serious in a baby, and the younger the infant, the more vulnerable they are. This is also one reason why you should avoid kissing a baby on the mouth.

Changing trends

WHO’s recent figures brought together data from around the world to estimate the prevalence of genital herpes in 2020, compared with previous estimates in 2012 and 2016.

This data shows no significant difference in the prevalence of genital herpes caused by HSV-2 since 2016, but does highlight increases in genital herpes infections caused by HSV-1.

The estimated number of genital HSV-1 infections globally was nearly twice as high in 2020 compared with 2016 (376 million compared with 192 million).

A 2022 study looking at Australia, New Zealand and Canada found more than 60% of genital herpes infections are still caused by HSV-2. But this is declining by about 2% each year while new genital infections that result from HSV-1 are rising.

There’s no simple fix, but safe sex is important

Genital herpes causes a substantial disease burden and economic cost to health-care services.

With such a large proportion of the world’s population infected with HSV-1, evidence this virus is increasingly causing genital herpes is concerning.

There’s no cure for genital herpes, but some medications, such as antivirals, can help reduce the amount of virus present in the system. While this won’t kill it completely, it helps to prevent symptomatic genital herpes recurrences, improve quality of life, and minimise the risk of transmission.

To prevent the spread of genital herpes and other STIs, practise safe sex, particularly if you’re not sure of your partner’s sexual health. You need to use a barrier method such as condoms to protect against STIs (a contraceptive such as the pill won’t work). This includes during oral sex.

As herpes is now so common, testing is not usually included as part of a regular sexual health check-up, except for in specific circumstances such as during pregnancy or severe episodes.

So it’s wise not to let your guard down, even if your partner insists they have received the all-clear from a recent check-up.

If there are herpes lesions present around the genitals, avoid sex entirely. Even condoms are not fully effective at these times, as exposed areas can still transmit the infection.

Immune health

If you are infected with HSV-1 or HSV-2 it’s more likely symptoms will appear when you’re stressed, tired or overwhelmed. During these times, our immune system may not be as functional, and dormant viruses such as herpes can start to develop quickly in our bodies.

To reduce the risk of recurrent herpes infections, try to eat healthily, get at least seven hours of sleep each night if possible, and look out for when your body may be telling you to take a step back and relax. This self-care can go a long way towards keeping latent viruses at bay.

While the prevalence has increased significantly in recent years, we have not lost the war on genital herpes just yet. Safe sexual practices, education and awareness can help reduce its spread, and the stigma around it.

If you have personal concerns, you should discuss them with a medical professional.

  • Carrots vs Parsnips – Which is Healthier?

    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.

    Our Verdict

    When comparing carrots to parsnips, we picked the parsnips.

    Why?

    There are arguments for both! But we say parsnips win on overall nutritional density.

    In terms of macros, parsnips vary quite a lot from region to another, but broadly speaking, parsnips have more carbs and fiber, and/but the ratios are such that carrots have the lower glycemic index. We’ll call this one a win for carrots.

    When it comes to vitamins, carrots have more of vitamins A, B2, B3, B6, and choline, while parsnips have more of vitamins B1, B5, B9, C, E, and K. A small win for parsnips here.

    In the category of minerals, carrots are not higher in any minerals, while parsnips are higher in calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. An overwhelming win for parsnips.

    While the overall vitamin and mineral content puts parsnips ahead, it’s still worth noting that carrots have highly bioavailable megadoses of vitamin A.

    Another thing to note is that the glycemic index recorded for both is when peeled and boiled, whereas both of these root vegetables can be enjoyed raw if you wish, which has a much lower GI.

    In short, enjoy either or both, but parsnips are the more nutritionally dense overall.

  • Ready… Set… Flow!

    Time to make your new year plans? Or maybe you’ve already made a list, and you’re checking it twice. If so, now’s the time to make sure that your new year’s plans will flow:

    “Flow”, as you may be aware, is the psychological state generally defined as “a state in which we feel good about what we’re doing, and just keep doing it, at a peak performance level”; the term was coined by psychologist Mihaly Csikszentmihalyi and has risen to popularity since.

    We wrote about it a little before, here:

    Morning Routines That Just Flow

    The above article details how to start the perfect day, but how to start the perfect year? Firstly, it’s good to get the jump on the new year a little; see:

    The Science Of New Year’s Pre-Resolutions

    …and we also agree with Dr. Faye Bate, who preaches taking the path of least resistance when it comes to healthy habits:

    How To Actually Start A Healthy Lifestyle In The New Year

    Because…

    Getting into the flow

    The most hydrating drink is the one that [contains adequate water and] you will actually drink. The best exercise is the one you’ll do. The best sleep is the sleep you can actually get. And so on.

    We see this—or rather its evil counterpoint—a lot in diet culture. People frame their willpower against the temptations of donuts and whatever, and make Faustian bargains whereby they will eat food they find boring in the hopes it will bring them good health. And it won’t. Because, they’ll give up quickly.

    Instead, each part of our healthy life has to be engaged with with a sense of flow. Again, that’s: “a state in which we feel good about what we’re doing, and just keep doing it, at a peak performance level”

    So we need to find healthy recipes we like (check out our recipe section!), we need to find exercise that we like, we need to find an approach to sleep that the Geneva Convention wouldn’t consider a kind a torture, and so forth. And, ideally, not just “like” in the sense of “this is tolerable” but “like” in the sense of “I am truly passionate about this thing”.

    And that’s going to look different for each of us.

    Running is a great example of something that some people truly love, whereas others will do almost anything to avoid.

    And food? We’ve written before about the usefulness of a “to don’t” list; it’s like a “to do” list, but it’s things we’re not going to even try to do. For example, a person with two addictions is usually advised to quit one at a time, so quitting the other would go on a “to don’t” list for now. The same goes for food; you need to enjoy what you’re eating or you won’t “feel good about what we’re doing, and just keep doing it”, per flow. So, do not deprive yourself; it won’t work anyway; just pick one healthy change to make, and then queue up any other changes for once the first one has started feeling natural to you.

    For more on “to don’t” lists and other such tricks, see: How To Keep On Keeping On… Long Term!

    Staying in the flow

    …is not usually a problem, you would think, because “…and just keep doing it, at peak performance level” but the fact is, sometimes we get kicked out of our flow by something external. We covered some of that in the above-linked “How To Keep On Keeping On” article, such as figuring out showstoppers in advance (for example, “if I get an injury, I will rest until it is healed”) and ideally, back-up plans.

    For example, let’s say you have your dietary plan all worked out, then you are invited to someone’s birthday celebration a couple of weeks in, and you don’t want to rain on their parade, so you figure out for yourself in advance how you are going to mitigate any harm to your plans, e.g. “I will simply choose the healthiest option available, and not worry if it doesn’t meet my usual standards” or “I will simply fast” if that’s an appropriate thing for you (for some it might be, for some it might not be).

  • The Twenty-Four Hour Mind – by Dr. Rosalind Cartwright

    We’ve reviewed books about sleep before, and even about dreaming, so what does this one have to offer that’s new?

    Quite a lot, actually! Before Dr. Cartwright, there were mainly two models of sleep and dreaming:

    • The “top-down” model of psychoanalysts: our minds shape our dreams which in turn reveal things about us as people
    • The “bottom-up” model of neuroscientists: our brains need to go through regular maintaince cycles, of which vivid hallucinations are a quirky side-effect.

    And now, as Dr. Cartwright puts it:

    ❝I will lay out a new [horizontal] psychological model of the twenty-four hour mind; that is, how the predominantly conscious (waking) and unconscious (sleeping) forms of mental behavior interact through the brain’s regular, but differently organized, states of waking, sleeping, and dreaming.❞

    This she does in the exploratory style of a 224-page lecture, which sounds like it might be tedious, but is actually attention-grabbing and engaging throughout. This book is more of a page-turner than soporific bedtime reading!

    Bottom line: if you’d like to know more about the effect your waking and sleeping brain have on each other (to include getting in between those and making adjutments as appropriate), this is very much an elucidating read!

  • What Omega-3 Fatty Acids Really Do For Us

    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 Omega-3 Fatty Acids Really Do For Us

    Shockingly, we’ve not previously covered this in a main feature here at 10almonds… Mostly we tend to focus on less well-known supplements. However, in this case, the supplement may be well known, while some of its benefits, we suspect, may come as a surprise.

    So…

    What is it?

    In this case, it’s more of a “what are they?”, because omega-3 fatty acids come in multiple forms, most notably:

    • Alpha-linoleic acid (ALA)
    • Eicosapentaenoic acid (EPA)
    • Docosahexanoic acid (DHA)

    ALA is most readily found in certain seeds and nuts (chia seeds and walnuts are top contenders), while EPA and DHA are most readily found in certain fish (hence “cod liver oil” being a commonly available supplement, though actually cod aren’t even the best source—salmon and mackerel are better; cod is just cheaper to overfish, making it the cheaper supplement to manufacture).

    Which of the three is best, or do we need them all?

    There are two ways of looking at this:

    • ALA is sufficient alone, because it is a precursor to EPA and DHA, meaning that the body will take ALA and convert it into EPA and DHA as required
    • EPA and DHA are superior because they’re already in the forms the body will use, which makes them more efficient

    As with most things in health, diversity is good, so you really can’t go wrong by getting some from each source.

    Unless you have an allergy to fish or nuts, in which case, definitely avoid those!

    What do omega-3 fatty acids do for us, according to actual research?

    Against inflammation

    Most people know it’s good for joints, as this is perhaps what it’s most marketed for. Indeed, it’s good against inflammation of the joints (and elsewhere), and autoimmune diseases in general. So this means it is indeed good against common forms of arthritis, amongst others:

    Read: Omega-3 fatty acids in inflammation and autoimmune disease

    Against menstrual pain

    Linked to the above-referenced anti-inflammatory effects, omega-3s were also found to be better than ibuprofen for the treatment of severe menstrual pain:

    Don’t take our word for it: Comparison of the effect of fish oil and ibuprofen on treatment of severe pain in primary dysmenorrhea

    Against cognitive decline

    This one’s a heavy-hitter. It’s perhaps to be expected of something so good against inflammation (bearing in mind that, for example, a large part of Alzheimer’s is effectively a form of inflammation of the brain); as this one’s so important and such a clear benefit, here are three particularly illustrative studies:

    Against heart disease

    The title says it all in this one:

    A meta-analysis shows that docosahexaenoic acid from algal oil reduces serum triglycerides and increases HDL-cholesterol and LDL-cholesterol in persons without coronary heart disease

    But what about in patients who do have heart disease?

    Mozaffarian and Wu did a huge meta-review of available evidence, and found that in fact, of all the studied heart-related effects, reducing mortality rate in cases of cardiovascular disease was the single most well-evidenced benefit:

    Read more: Omega-3 fatty acids and cardiovascular disease: effects on risk factors, molecular pathways, and clinical events

    How much should we take?

    There’s quite a bit of science on this, and—which is unusual for something so well-studied—not a lot of consensus.

    However, to summarize the position of the academy of nutrition and dietetics on dietary fatty acids for healthy adults, they recommend a minimum of 250–500 mg combined EPA and DHA each day for healthy adults. This can be obtained from about 8 ounces (230g) of fatty fish per week, for example.

    If going for ALA, on the other hand, the recommendation becomes 1.1g/day for women or 1.6g/day for men.

  • Sleep wrinkles are real. Here’s how they leave their mark

    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.

    You wake up, stagger to the bathroom and gaze into the mirror. No, you’re not imagining it. You’ve developed face wrinkles overnight. They’re sleep wrinkles.

    Sleep wrinkles are temporary. But as your skin loses its elasticity as you age, they can set in.

    Here’s what you can do to minimise the chance of them forming in the first place.

    How side-sleeping affects your face

    Your skin wrinkles for a number of reasons, including ageing, sun damage, smoking, poor hydration, habitual facial expressions (such as grinning, pouting, frowning, squinting) and sleeping positions.

    When you sleep on your side or stomach, your face skin is squeezed and crushed a lot more than if you sleep on your back. When you sleep on your side or stomach, gravity presses your face against the pillow. Your face skin is distorted as your skin is stretched, compressed and pulled in all directions as you move about in your sleep.

    You can reduce these external forces acting on the face by sleeping on your back or changing positions frequently.

    Doctors can tell which side you sleep on by looking at your face

    In a young face, sleep wrinkles are transient and disappear after waking.

    Temporary sleep wrinkles can become persistent with time and repetition. As we age, our skin loses elasticity (recoil) and extensibility (stretch), creating ideal conditions for sleep wrinkles or lines to set in and last longer.

    The time spent in each sleeping position, the magnitude of external forces applied to each area of the face, as well as the surface area of contact with the pillow surface, also affects the pattern and rate of sleep wrinkle formation.

    Skin specialists can often recognise this. People who favour sleeping on one side of their body tend to have a flatter face on their sleeping side and more visible sleep lines.

    Can a night skincare routine avoid sleep wrinkles?

    Collagen and elastin are two primary components of the dermis (inner layer) of skin. They form the skin structure and maintain the elasticity of skin.

    Supplementing collagen through skincare routines to enhance skin elasticity can help reduce wrinkle formation.

    Hyaluronic acid is a naturally occurring molecule in human bodies. It holds our skin’s collagen and elastin in a proper configuration, stimulates the production of collagen and adds hydration, which can help slow down wrinkle formation. Hyaluronic acid is one of the most common active ingredients in skincare creams, gels and lotions.

    Moisturisers can hydrate the skin in different ways. “Occlusive” substances produce a thin layer of oil on the skin that prevents water loss due to evaporation. “Humectants” attract and hold water in the skin, and they can differ in their capacity to bind with water, which influences the degree of skin hydration.

    Do silk pillowcases actually make a difference?

    Can they help? New Africa/Shutterstock

    Silk pillowcases can make a difference in wrinkle formation, if they let your skin glide and move, rather than adding friction and pressure on a single spot. If you can, use silk sheets and silk pillows.

    Studies have also shown pillows designed to reduce mechanical stress during sleep can prevent skin deformations. Such a pillow could be useful in slowing down and preventing the formation of certain facial wrinkles.

    Sleeping on your back can reduce the risk of sleep lines, as can a nighttime routine of moisturising before sleep.

    Otherwise, lifestyle choices and habits, such quitting smoking, drinking plenty of water, a healthy diet (eating enough vegetables, fruits, nuts, seeds, healthy fats, yogurt and other fermented foods) and regular use of sunscreens can help improve the appearance of the skin on our face.

  • Celery vs Radish – Which is Healthier?

    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.

    Our Verdict

    When comparing celery to radish, we picked the celery.

    Why?

    It was very close! And yes, surprising, we know. Generally speaking, the more colorful/pigmented an edible plant is, the healthier it is. Celery is just one of those weird exceptions (as is cauliflower, by the way).

    Macros-wise, these two are pretty much the same—95% water, with just enough other stuff to hold them together. The proportions of “other stuff” are also pretty much equal.

    In the category of vitamins, celery has more vitamin K while radish has more vitamin C; the other vitamins are pretty close to equal. We’ll call this one a minor win for celery, as vitamin K is found in fewer foods than vitamin C.

    When it comes to minerals, celery has more calcium, manganese, phosphorus, and potassium, while radish has more copper, iron, selenium, and zinc. We’ll call this a minor win for radish, as the margins are a little wider for its minerals.

    So, that makes the score 1–1 so far.

    Both plants have an assortment of polyphenols, of which, when we add up the averages, celery comes out on top by some way. Celery also comes out on top when we do a head-to-head of the top flavonoid of each; celery has 5.15mg/100g of apigenin to radish’s 0.63mg/100g kaempferol.

    Which means, both are great healthy foods, but celery wins the day.
