Can you ‘boost’ your immune system?

As flu season and a likely winter COVID-19 wave approach, you may encounter both proven and unproven methods claiming to “boost” your immune system. Before you reach for supplements, learn more about how the immune system works, how vaccines give us the best protection against many illnesses, and how some lifestyle factors can help your immune system function properly.
What is the immune system?
The immune system is the body’s first line of defense against invaders like viruses, bacteria, or fungi. You develop immunity—or protection from infection—when your immune system has learned how to recognize an invader and attack it before it makes you sick.
How can you boost your immune system?
You can teach your immune system how to fight back against dangerous invaders by staying up to date on vaccines. This season’s updated flu and COVID-19 vaccines target newer variants and are recommended for everyone 6 months and older.
Vaccines reduce your risk of getting sick and spreading illness to others. Even if you get infected with a disease after you’ve been vaccinated against it, the vaccine will still increase protection against severe illness, hospitalization, and death.
People who have compromised immune systems due to certain health conditions or because they need to take immunosuppressant medications may need additional vaccine doses.
Find out which vaccines you and your children need by using the CDC’s Adult Vaccine Assessment Tool and Child and Adolescent Vaccine Assessment Tool. Talk to your health care provider about the best vaccines for your family.
Find pharmacies offering updated flu and COVID-19 vaccines by visiting Vaccines.gov.
Can supplements boost your immune system?
Many vitamin, mineral, and herbal supplements that are marketed as “immune boosting” have little to no effect on your immune system. Research is split on whether some of these supplements—like vitamin C, vitamin D, and zinc—are capable of helping your body fight infections.
Plus, the Food and Drug Administration typically does not review supplements until after they have reached store shelves, and companies can sell supplements without notifying the FDA. This means that supplements may not be accurately labeled.
Eating a diverse diet rich in fruits and vegetables is the best way for most people to absorb nutrients that support optimal immune system function. People with certain health conditions and deficiencies may need specific supplements prescribed by a health care provider. For example, people with anemia may need iron supplements in order to maintain appropriate iron levels.
Before you begin taking a new supplement, talk to your health care provider, as some supplements may interact with medications you are taking or worsen certain health conditions.
Can lifestyle factors strengthen your immune system?
Based on current evidence, there is no direct link between lifestyle changes and enhanced immunity to infections. However, maintaining a healthy lifestyle through the following practices can help ensure that your immune system functions as it should:
- Eat a diet rich in fruits and vegetables.
- Exercise regularly.
- Don’t smoke.
- Limit or eliminate alcohol consumption.
- Get seven or more hours of sleep per night.
- Reduce stress.
Taking steps to avoid contact with germs also reduces your risk of getting sick. Safer sex barriers like condoms protect against HIV, while wearing a high-quality, well-fitting mask—especially in high-risk environments—protects against COVID-19. Both of these illnesses can reduce your production of white blood cells, which protect against infection.
For more information, talk to your health care provider.

Slowing the Progression of Cataracts
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.
Understanding Cataracts
Cataracts are natural and impact everyone.
That’s a bit of a daunting opening line, but as Dr. Michele Lee, a board-certified ophthalmologist, explains, cataracts naturally develop with age, and can be accelerated by factors such as trauma, certain medications, and specific eye conditions.
We know how important your vision is to you (we’ve had great feedback about the book Vision for Life) as well as our articles on how glasses impact your eyesight and the effects of using eye drops.
While complete prevention isn’t possible, steps such as those mentioned below can be taken to slow their progression.
Here is an overview of the video’s first 3 takeaways. You can watch the whole video below.
Protect Your Eyes from Sunlight
Simply put, UV light damages lens proteins, which (significantly) contributes to cataracts. Wearing sunglasses can supposedly prevent up to 20% of cataracts caused by UV exposure.
Moderate Alcohol Consumption
We all, at some level, know that alcohol consumption doesn’t do us any good. Your eye health isn’t an exception to the rule; alcohol has been shown to contribute to cataract development.
If you’re looking at reducing your alcohol use, try reading this guide on lowering, or eradicating, alcohol consumption.
Avoid Smoking
Smokers are 2-3 times more likely to develop cataracts. Additionally, ensure good ventilation while cooking to avoid exposure to harmful indoor smoke.
See all 5 steps in the below video:

Beyond Supplements: The Real Immune-Boosters!
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.
The Real Immune-Boosters
What comes to your mind when we say “immune support”? Vitamin C and maybe zinc? Those have their place, but there are things we can do that are a lot more important!
It’s just, these things are not talked about as much, because stores can’t sell them to you
Sleep
One of the biggest difference-makers. Get good sleep! Getting at least 7 hours decent sleep (not lying in bed, not counting interruptions to sleep as part of the sleep duration) can improve your immune system by three or four times.
Put another way, people are 3–4 times more likely to get sick if they get less sleep than that on average.
Check it out: Behaviorally Assessed Sleep and Susceptibility to the Common Cold
Eat an anti-inflammatory diet
In short, for most of us this means lots of whole plant foods (lots of fiber), and limited sugar, flour, alcohol.
For more details, you can see our main feature on this: Keep Inflammation At Bay!
You may wonder why eating to reduce inflammation (inflammation is a form of immune response) will help improve immune response. Put it this way:
If your town’s fire service is called out eleventy-two times per day to deal with things that are not, in fact, fires, then when there is a fire, they will be already exhausted, and will not do their job so well.
Look after your gut microbiota
Additionally, healthy gut microbiota (fostered by the same diet we just described) help keep your body pathogen-free, by avoiding “leaky gut syndrome” that occurs when, for example, C. albicans (you do not want this in your gut, and it thrives on the things we just told you to avoid) puts its roots through your intestinal walls, making holes in them. And through those holes? You definitely do not want bacteria from your intestines going into the rest of your body.
See also: Gut Health 101
Actually get that moderate exercise
There’s definitely a sweet-spot here, because too much exercise will also exhaust you and deplete your body’s resources. However, the famous “150 minutes per week” (so, a little over 20 minutes per day, or 25 minutes per day with one day off) will make a big difference.
See: Exercise and the Regulation of Immune Functions
Manage your stress levels (good and bad!)
This one swings both ways:
- Acute stress (like a cold shower) is good for immune response. Think of it like a fire drill for your body.
- Chronic stress (“the general everything” persistently stressful in life) is bad for immune response. This is the fire drill that never ends. Your body’s going to know what to do really well, but it’s going to be exhausted already by the time an actual threat hits.

Supplement, yes.
These are far less critical than the above things, but are also helpful. Good things to take include:
Enjoy, and stay well!

Mythbusting The Big O
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.
“Early To Bed…”
In yesterday’s newsletter, we asked you for your (health-related) views on orgasms.
But what does the science say?
Orgasms are essential to good health: True or False?
False, in the most literal sense. One certainly won’t die without them. Anorgasmia (the inability to orgasm) is a condition that affects many postmenopausal women, some younger women, and some men. And importantly, it isn’t fatal—just generally considered unfortunate:
Anorgasmia Might Explain Why You’re Not Orgasming When You Want To
That article focuses on women; here’s a paper focusing on men:
Orgasms are good for the health, but marginally: True or False?
True! They have a wide array of benefits, depending on various factors (including, of course, one’s own sex). That said, the benefits are so marginal that we don’t have a flock of studies to cite, and are reduced to pop-science sources that verbally cite studies that are, alas, nowhere to be found, for example:
- For women: 9 Orgasm Benefits That Might Surprise You
- For men: 9 Ways Orgasms May Benefit Your Health
Doubtlessly the studies do exist, but are sparse enough that finding them is a nightmare as the keywords for them will bring up a lot of studies about orgasms and health that aren’t answering the above question (usually: health’s affect on orgasms, rather than the other way around).
There is some good science for post-menopausal women, though! Here it is:
Misconceptions About Sexual Health in Older Women
(if you have the time to read this, this also covers many very avoidable things that can disrupt sexual function, in ways that people will errantly chalk up to old age, not knowing that they are missing out needlessly)
Orgasms are good or bad, depending on being male or female: True or False
False, broadly. The health benefits are extant and marginal for almost everyone, as indicated above.
What’s that “almost” about, then?
There are a very few* people (usually men) for whom it doesn’t go well. In such cases, they have a chronic and lifelong problem whereby orgasm is followed by 2–7 days of flu-like and allergic symptoms. Little is known about it, but it appears to be some sort of autoimmune disorder.
Read more: Post-orgasmic illness syndrome: history and current perspectives
*It’s hard to say for sure how few though, as it is surely under-reported and thus under-diagnosed; likely even misdiagnosed if the patient doesn’t realize that orgasms are the trigger for such episodes, and the doctor doesn’t think to ask. Instead, they will be busy trying to eliminate foods from the diet, things like that, while missing this cause.
Orgasms are better avoided for optimal health: True or False?
Aside from the above, False. There is a common myth for men of health benefits of “semen retention”, but it is not based in science, just tradition. You can read a little about it here:
The short version is: do it if you want; don’t if you don’t; the body will compensate either way so it won’t make a meaningful difference to anything for most people, healthwise.
Small counterpoint: while withholding orgasm (and ejaculation) is not harmful to health, what does physiologically need draining sometimes is prostate fluid. But that can also be achieved mechanically through prostate milking, or left to fend for itself (as it will in nocturnal emissions, popularly called wet dreams). However, if you have problems with an enlarged prostate, it may not be a bad idea to take matters into your own hands, so to speak. As ever, do check with your doctor if you have (or think you may have) a condition that might affect this.
One final word…
We’re done with mythbusting for today, but we wanted to share this study that we came across (so to speak) while researching, as it’s very interesting:
On which note: if you haven’t already, consider getting a “magic wand” style vibe; you can thank us later (this writer’s opinion: everyone should have one!).
Top tip: do get the kind that plugs into the wall, not rechargeable. The plug-into-the-wall kind are more powerful, and last much longer (both “in the moment”, and in terms of how long the device itself lasts).
Enjoy!

The Lymphatic System Against Cancer & More
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.
Ask Not What Your Lymphatic System Can Do For You…
Just kidding; we’ll cover that first, as it’s definitely not talked about enough.
The lymphatic system is the system in the body that moves lymph around. It’s made of glands, nodes, and vessels:
- The glands (such as the tonsils and the adenoids) and nodes filter out bacteria and produce white blood cells. Specific functions may be, well, specialized—beyond the scope of today’s article—but that’s the broad function.
- The vessels are the tubes that allow those things to be moved around, suspended in lymph.
What’s lymph? It’s a colorless water-like liquid that transports immune cells, nutrients (and waste) around the body (through the lymphatic system).
Yes, it works alongside your vasculature; when white blood cells aren’t being deployed en masse into your bloodstream to deal with some threat, they’re waiting in the wings in the lymphatic system.
While your blood is pumped around by your heart, lymph moves based on a variety of factors, including contractions of small specialized lymphatic muscles, the pressure gradient created by the combination of those and gravity, and the movements of your body itself.
Here’s a larger article than we have room for, with diagrams we also don’t have room for:
Modelling the lymphatic system
To oversimplify it in few words for the sake of moving on: you can most of the time: think of it as an ancillary network supporting your circulatory system that unlike blood, doesn’t deal with oxygen or sugars, but does deal with a lot of other things, including:
- water and salt balance
- immune cells and other aspects of immune function
- transports fats (and any fat-soluble vitamins in them) into circulation
- cleans up stuff that gets stuck between cells
- general detoxification
There’s a lot that can go wrong if lymph isn’t flowing as it should
Too much to list here, but to give an idea:
- Arthritis and many autoimmune diseases
- Cardiovascular disease and metabolic syndrome
- Obesity, diabetes, and organ failure
- Alzheimer’s and other dementias
- Lymphadenitis, lymphangitis, and lymphedenopathy
- Lymphomas and Hodgkin’s disease (both are types of lymphatic cancer)
- Cancers of other kinds, because of things not being cleaned up where and when they should be
Yikes! That’s a lot of important things for a mostly-forgotten system to be taking care of protecting us from!
What you can do for your lymphatic system, to avoid those things!
Happily, there are easy things we can do to give our lymph some love, such as:
Massage therapy (and foam rolling)
This is the go-to that many people/publications recommend. It’s good! It’s certainly not the most important thing to do, but it’s good.
You can even use a simple gadget like this one to help move the lymph around, without needing to learn arcane massage techniques.
Exercise (move your body!)
This is a lot more important. The more we move our body, the more lymph moves around. The more lymph moves around today, the more easily it will move around tomorrow. A healthy constant movement of lymph throughout the lymphatic system is key to keeping everything running smoothly.
If you pick only one kind of exercise, make it High-Intensity Interval Training (HIIT):
How To Do HIIT (Without Wrecking Your Body)
If for some reason you really can’t do that, just spend as much of your waking time as reasonably possible, moving, per:
For ideas on how to do that, check out…
Get thee to a kitchen
This is about getting healthy food that gives your body’s clean-up crew (the lymphatic system) an easier time of it.
Rather than trying to “eat clean” which can be a very nebulous term and it’s often not at all clear (and/or hotly debated) what counts as “clean”, instead, stick to foods that constitute an anti-inflammatory diet:
Take care!

Patient Underwent One Surgery but Was Billed for Two. Even After Being Sued, She Refused To Pay.
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.
Jamie Holmes says a surgery center tried to make her pay for two operations after she underwent only one. She refused to buckle, even after a collection agency sued her last winter.
Holmes, who lives in northwestern Washington state, had surgery in 2019 to have her fallopian tubes tied, a permanent birth-control procedure that her insurance company agreed ahead of time to cover.
During the operation, while Holmes was under anesthesia, the surgeon noticed early signs of endometriosis, a common condition in which fibrous scar tissue grows around the uterus, Holmes said. She said the surgeon later told her he spent about 15 minutes cauterizing the troublesome tissue as a precaution. She recalls him saying he finished the whole operation within the 60 minutes that had been allotted for the tubal ligation procedure alone.
She said the doctor assured her the extra treatment for endometriosis would cost her little, if anything.
Then the bill came.
The Patient: Jamie Holmes, 38, of Lynden, Washington, who was insured by Premera Blue Cross at the time.
Medical Services: A tubal ligation operation, plus treatment of endometriosis found during the surgery.
Service Provider: Pacific Rim Outpatient Surgery Center of Bellingham, Washington, which has since been purchased, closed, and reopened under a new name.
Total Bill: $9,620. Insurance paid $1,262 to the in-network center. After adjusting for prices allowed under the insurer’s contract, the center billed Holmes $2,605. A collection agency later acquired the debt and sued her for $3,792.19, including interest and fees.
What Gives: The surgery center, which provided the facility and support staff for her operation, sent a bill suggesting that Holmes underwent two separate operations, one to have her tubes tied and one to treat endometriosis. It charged $4,810 for each.
Holmes said there were no such problems with the separate bills from the surgeon and anesthesiologist, which the insurer paid.
Holmes figured someone in the center’s billing department mistakenly thought she’d been on the operating table twice. She said she tried to explain it to the staff, to no avail.
She said it was as if she ordered a meal at a fast-food restaurant, was given extra fries, and then was charged for two whole meals. “I didn’t get the extra burger and drink and a toy,” she joked.
Her insurer, Premera Blue Cross, declined to pay for two operations, she said. The surgery center billed Holmes for much of the difference. She refused to pay.
Holmes said she understands the surgery center could have incurred additional costs for the approximately 15 minutes the surgeon spent cauterizing the spots of endometriosis. About $500 would have seemed like a fair charge to her. “I’m not opposed to paying for that,” she said. “I am opposed to paying for a whole bunch of things I didn’t receive.”
The physician-owned surgery center was later purchased and closed by PeaceHealth, a regional health system. But the debt was turned over to a collection agency, SB&C, which filed suit against Holmes in December 2023, seeking $3,792.19, including interest and fees.
The collection agency asked a judge to grant summary judgment, which could have allowed the company to garnish wages from Holmes’ job as a graphic artist and marketing specialist for real estate agents.
Holmes said she filed a written response, then showed up on Zoom and at the courthouse for two hearings, during which she explained her side, without bringing a lawyer. The judge ruled in February that the collection agency was not entitled to summary judgment, because the facts of the case were in dispute.

Representatives of the collection agency and the defunct surgery center declined to comment for this article.
Sabrina Corlette, co-director of Georgetown University’s Center on Health Insurance Reforms, said it was absurd for the surgery center to bill for two operations and then refuse to back down when the situation was explained. “It’s like a Kafka novel,” she said.
Corlette said surgery center staffers should be accustomed to such scenarios. “It is quite common, I would think, for a surgeon to look inside somebody and say, ‘Oh, there’s this other thing going on. I’m going to deal with it while I’ve got the patient on the operating table.’”
It wouldn’t have made medical or financial sense for the surgeon to make Holmes undergo a separate operation for the secondary issue, she said.
Corlette said that if the surgery center was still in business, she would advise the patient to file a complaint with state regulators.
The Resolution: So far, the collection agency has not pressed ahead with its lawsuit by seeking a trial after the judge’s ruling. Holmes said that if the agency continues to sue her over the debt, she might hire a lawyer and sue them back, seeking damages and attorney fees.
She could have arranged to pay off the amount in installments. But she’s standing on principle, she said.
“I just got stonewalled so badly. They treated me like an idiot,” she said. “If they’re going to be petty to me, I’m willing to be petty right back.”
The Takeaway: Don’t be afraid to fight a bogus medical bill, even if the dispute goes to court.
Debt collectors often seek summary judgment, which allows them to garnish wages or take other measures to seize money without going to the trouble of proving in a trial that they are entitled to payments. If the consumers being sued don’t show up to tell their side in court hearings, judges often grant summary judgment to the debt collectors.
However, if the facts of a case are in dispute — for example, because the defendant shows up and argues she owes for just one surgery, not two — the judge may deny summary judgment and send the case to trial. That forces the debt collector to choose: spend more time and money pursuing the debt or drop it.
“You know what? It pays to be stubborn in situations like this,” said Berneta Haynes, a senior attorney for the National Consumer Law Center who reviewed Holmes’ bill for KFF Health News.
Many people don’t go to such hearings, sometimes because they didn’t get enough notice, don’t read English, or don’t have time, she said.
“I think a lot of folks just cave” after they’re sued, Haynes said.

Gut-Healthy Spaghetti Chermoula
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.
Chermoula is a Maghreb relish/marinade (it’s used for both purposes); it’s a little like chimichurri but with distinctly N. African flavors. The gut-healthiness starts there (it’s easy to forget that olives—unless fresh—are a fermented food full of probiotic Lactobacillus sp. and thus great for the gut even beyond their fiber content), and continues in the feta, the vegetables, and the wholewheat nature of the pasta. The dish can be enjoyed at any time, but it’s perfect for warm summer evenings—perhaps dining outside, if you’ve place for that.
You will need
- 9oz wholewheat spaghetti (plus low-sodium salt for its water)
- 10oz broccoli, cut into small florets
- 3oz cilantro (unless you have the soap gene)
- 3oz parsley (whether or not you included the cilantro)
- 3oz green olives, pitted, rinsed
- 1 lemon, pickled, rinsed
- 1 bulb garlic
- 3 tbsp pistachios, shelled
- 2 tbsp mixed seeds
- 1 tsp cumin
- 1 tsp chili flakes
- ½ cup extra virgin olive oil
- For the garnish: 3oz feta (or plant-based equivalent), crumbled, 3oz sun-dried tomatoes, diced, 1 tsp cracked black pepper
Note: why are we rinsing the things? It’s because while picked foods are great for the gut, the sodium can add up, so there’s no need to bring extra brine with them too. By doing it this way, there’ll be just the right amount for flavor, without overdoing it.
Method
(we suggest you read everything at least once before doing anything)
1) Cook the spaghetti as you normally would, but when it’s a minute or two from being done, add the broccoli in with it. When it’s done, drain and rinse thoroughly to get rid of excess starch and salt, and also because cooling it even temporarily (as in this case) lowers its glycemic index.
2) Put the rest of the ingredients into a food processor (except the olive oil and the garnish), and blitz thoroughly until no large coarse bits remain. When that’s done, add the olive oil, and pulse it a few times to combine. We didn’t add the olive oil previously, because blending it so thoroughly in that state would have aerated it in a way we don’t want.
3) Put ⅔ of the chermoula you just made into the pan you used for cooking the spaghetti, and set it over a medium heat. When it starts bubbling, return the spaghetti and broccoli to the pan, mixing gently but thoroughly. If the pasta threatens to stick, you can add a little more chermoula, but go easy on it. Any leftover chermoula that you didn’t use today, can be kept in the fridge and used later as a pesto.
4) Serve! Add the garnish as you do.
Enjoy!
