Don’t let bad advice lead your immune system astray. Find out which immunity-boosting tips are nothing more than myths – and what you should actually do to stay healthy when cold.

If you don’t want an aching throat, stuffed-up sinuses or any of the other hallmark symptoms of cold and flu season, you’ve got to get your immune system in shape. There are plenty of tips, tricks and even over-the-counter remedies that promise to give you better immunity – but that doesn’t mean you should use them. It might surprise you, but some of the best-known immunity-boosting advice is nothing more than a myth.

We’re busting some of the most common immunity myths. Get the facts on how you should eat, fine-tune supplements and adjust your lifestyle to help keep colds, flus and other illnesses at bay.

One of the most prevalent immunity myths out there? Taking a whole bunch of vitamin C will kick a cold before it even begins, or shorten the cold’s lifespan if you’re already sick.

While vitamin C is a great natural immunity booster, it isn’t exactly the cure-all it’s often advertised as. This nutrient does play an important role in immune function, and taking vitamin C supplements can be beneficial. But you don’t want to overdo it, especially if you’re planning to dramatically up your vitamin C intake.

More isn’t always better when it comes to vitamin C. Your body can only absorb so much – and the rest just goes to waste. Stick to the daily recommended dose for adults, which is 60 to 95 milligrams, and don’t go above the upper limit of 2,000 milligrams per day. Getting too much vitamin C can cause problems of its own like nausea, headaches and vomiting.

Plus, research has shown that taking huge doses of vitamin C supplements doesn’t actually help you fight off illness. While this nutrient can be beneficial for immune health overall, it doesn’t have any apparent advantage when you’re trying to keep colds at bay.

Here’s a myth that’s often found alongside the previous: You’ve got to take more zinc if you want to shorten a cold.

Zinc, like vitamin C, can have a positive effect on your immune system. It can help with everything from wound healing to immune cell function. And it’s often touted as one of the best minerals for slashing a cold’s typical lifespan to help you feel better faster.

However, zinc isn’t exactly the cold-curing powerhouse you might think it is. While a research study from 1984 did show that zinc supplements may be able to reduce a cold’s severity, more recent results are mixed. As the Mayo Clinic explains, an analysis of multiple studies found that taking zinc supplements within 24 hours of the first signs of cold may reduce the length of your illness by one day. But all of the studies reviewed were limited – they featured too few participants, used different dosages and forms of zinc, and supplemented zinc for varying amounts of time.

So, there’s no truly conclusive proof that zinc will zap your cold in its tracks. It isn’t a bad idea to take zinc – but there’s no reason to go overboard. Large amounts of zinc can be toxic to the body, so make sure you stick with the daily recommended amount for adults to be safe and get what your immune system needs. 8 milligrams for women and 11 milligrams for men daily is just right.

There’s one more must-remember tip about taking zinc. You don’t want to take this supplement on an empty stomach. Doing so can cause nausea – an added symptom you definitely don’t need if you’re already suffering from a cold or the flu.

Citrus fruits are rich in vitamin C, which we know is a much-beloved immunity-boosting nutrient. But just like you learned above, vitamin C isn’t the be-all, end-all for your health and your immune system’s strength. And it’s certainly no cure-all for colds and flus.

Many people turn to citrus fruit in an effort to increase their vitamin C intake naturally. But while the citrus family does offer a lot of vitamin C, it isn’t the only immunity-boosting powerhouse. There are plenty of other immunity superfoods that can deliver the nutrients you need to stay healthy even during cold and flu season.

Citrus fruits contain plenty of vitamin C – a 100-gram serving of lemon, for example, provides 53 mg while a 100-gram serving of oranges offers 71 mg. But there are other foods, including meat and veggies, that can offer just as much of this key immunity nutrient. Here’s a sample of some other awesome options rich in vitamin C:

Plus, don’t forget that no fruit, veggie or any other food is a cure-all. While vitamin C is a good nutrient to look for, you can also find immunity helpers in foods like chicken (which is rich in zinc as well as vitamin B6), carrots (which contain vitamin A) and even bone broth. It’s a good idea to eat a balanced diet so your immune system gets every one of the nutrients you need for great overall health.

Your diet definitely plays a role in your immune system’s health and function. But believing that you can simply eat a ton of immunity-boosting foods – or take a bunch of immunity-strengthening supplements – to stay healthy, that’s a myth.

While a diet rich in immunity-friendly nutrients is crucially important for keeping your immune system strong, there are a whole bunch of lifestyle factors that can impact your health. And if your lifestyle isn’t also supporting your immune system, you could wind up canceling out all the good that food and supplements can offer.

Sleep and stress are two of the biggest lifestyle factors to pay attention to. If you aren’t getting enough sleep, you’re weakening your immune system, potentially causing inflammation and stressing yourself out. Try our tips to get a better night’s sleep every time you head to bed. And when it comes to stress, missing out on sleep can lead to increased cortisol (the stress hormone). So if you’re already feeling stressed out by work, your busy schedule or your social life, you’ll also weaken your immune system and up your odds of getting sick. Try creating a calming, relaxing ritual at home with essential oils, meditation or other stress-soothing activities you enjoy.

Additionally, it’s another myth that exercising isn’t good for your immune system. Exercise is actually one of the best ways to boost your immunity – working out helps combat stress and benefits your overall health. Try to fit in regular exercise so you’re getting your heart pumping each and every day, even if you’re taking walks or sticking with short bursts of intense activity.

Sure, fresh fruits and vegetables are fantastic for delivering the nutrients you need, whether you’re targeting your immune system or other health needs. But that doesn’t mean you should only consume fresh produce – there are other forms that can offer just as many essential nutrients, and they won’t spoil as quickly.

It’s tough to get your hands on quality fresh produce in the colder months. But you shouldn’t worry about reaching for canned veggies or frozen fruit. It’s a common immunity myth that only fresh produce will do. Both canned and frozen fruits and vegetables are great sources of nutrients, and they can help you ensure you’re getting plenty of healthy variety into your diet.

Plus, as Tufts University explains, frozen can be even better than fresh in some cases. Research has discovered that frozen produce of all different varieties have almost identical nutritional value compared to their fresh counterparts. And while fresh produce can lose vitamins after just 5 days inside your fridge, frozen fruits and veggies maintain their freshness and won’t lose any nutrients. In tests, frozen fruits and vegetables were found to have higher levels of vitamin C – a key immunity booster – along with more antioxidant compounds, lutein and beta-carotene than fresh produce after refrigeration.

Canned fruits and vegetables are similar to frozen varieties. The produce is picked at just the right ripeness, and the nutrients are essentially “locked in” during the canning process when the fruits and vegetables are preserved. This leads canned foods to keep their high nutrient levels regardless of their time on your shelf. Some research has even suggested that eating a good amount of canned fruits and veggies in addition to your usual fresh produce can deliver higher levels of essential nutrients than opting for fresh alone.

Just make sure you’re choosing canned fruits and vegetables that don’t contain additives so you’re getting the nutrients you need without anything else. Look for canned produce in its simplest form, with no additives included in the mix. And don’t forget about BPA. While some canned food manufacturers have begun phasing BPA linings out of their canned goods, it’s still possible to pick up canned produce that includes BPA – so take a close look for a Proposition 65 warning label that can indicate the presence of this harmful substance.

So, while fresh is usually best, it isn’t the only option for a healthy immune system. If you want to stock up while you’re at the store, canned and frozen produce are both solid choices. Or, if you aren’t going to eat your fresh produce ASAP, opt for frozen or canned so you can lock in nutrients without worrying about freshness.

The prospect of seeing one of athletics' biggest stars back on the track is growing stronger, with Jakob Ingebrigtsen reportedly targeting a return to competition later this summer following his recovery from Achilles tendon surgery.

According to comments made by his agent, Daniel Wessfeldt, in an interview with Norwegian media, the double Olympic champion could make his long-awaited comeback at one of three major European meetings in July. The leading options under consideration are the Monaco Diamond League on July 10, the Hungarian Athletics Grand Prix on July 14, and the London Diamond League on July 18.

For athletics fans, the possibility of Ingebrigtsen lining up in London would add another layer of excitement to an already highly anticipated Diamond League meeting. The Norwegian middle-distance sensation has become one of the sport's most dominant figures in recent years, collecting Olympic, world and European titles while consistently rewriting record books.

His 2026 campaign was put on hold after he underwent surgery on his Achilles tendon earlier this year, forcing him to focus on rehabilitation rather than competition. Since then, questions have surrounded when the 24-year-old would be ready to return to racing.

The latest update suggests that decision will largely depend on how his training progresses over the coming weeks. If recovery continues according to plan, July could mark the beginning of his return to elite competition ahead of the latter stages of the season.

A comeback at either Monaco, Budapest or London would immediately place Ingebrigtsen back among the sport's biggest storylines. Each meeting is renowned for producing world-class performances, and any appearance by the Norwegian would attract significant attention from fans eager to see how quickly he can regain top form after his injury setback.

While no final decision has been confirmed, the signs are increasingly positive. After months away from competition, Jakob Ingebrigtsen appears to be edging closer to a return, with London's Diamond League meeting emerging as one of the most intriguing possibilities on his road back to the track.

Should his recovery continue smoothly, athletics could soon welcome back one of its brightest and most influential stars.

What should have been the defining moment of Emad Bashir-Mohammed's young running career instead turned into one of the most talked-about controversies in American road racing this year.

The 23-year-old crossed the finish line first in the men's citizen's race at the prestigious Bolder Boulder 10K on Memorial Day in Colorado, stopping the clock at an impressive 29:50. His performance was not only a commanding victory but also one of the fastest winning times ever recorded in the event's long and celebrated history. Bashir-Mohammed finished eight seconds clear of his nearest challenger and appeared to have secured a breakthrough triumph.

For nearly two hours, he was the undisputed winner.

Then everything changed.

Race officials announced that Bashir-Mohammed had been disqualified after determining that he had started in the wrong wave. According to Bolder Boulder regulations, he had been assigned to the AA wave but lined up with the faster A wave, which began earlier. Event rules allow runners to move backward into a slower wave, but prohibit athletes from advancing into a faster one.

As a result, Bashir-Mohammed's victory was erased from the record books.

The citizen's title was subsequently awarded to Nickolas Scudder, who crossed the line second in 29:58. The promotion handed Scudder back-to-back citizen's race victories, while Bashir-Mohammed was left to grapple with the disappointment of losing a win he believed he had earned on the road.

The disqualification has since ignited widespread debate across the running community.

Bashir-Mohammed maintains that he did not intentionally violate the rules. He claims that after collecting his AA bib, he spoke with race personnel and was permitted to start with the A wave after presenting evidence of his recent performances. In a statement shared after the race, he expressed frustration over the decision, arguing that his goal was simply to compete against the strongest field available and produce the fastest time possible.

Race organizers, however, stood firmly behind their ruling. Officials stated that wave-assignment regulations are clearly communicated in pre-race information and reiterated during packet collection. They also noted that hundreds of participants are disqualified each year for moving into faster start groups, emphasizing that consistent enforcement is necessary to maintain fairness for all competitors.

The incident has divided opinion among runners and fans alike. Some believe the rules must be applied equally regardless of an athlete's finishing position, arguing that wave assignments are a fundamental part of race organization. Others feel the punishment is harsh, particularly if Bashir-Mohammed genuinely received approval to move up before the start.

What remains undisputed is the quality of his performance. On the roads of Boulder, Bashir-Mohammed demonstrated the fitness and speed required to outrun the field by a significant margin. Yet in road racing, crossing the finish line first is only part of the equation. Compliance with race regulations carries equal weight.

For Bashir-Mohammed, the day will be remembered as a painful lesson in the fine margins that can define elite competition. A remarkable run delivered a memorable victory, but a dispute over wave placement ultimately overshadowed the achievement, leaving behind a controversy that continues to fuel discussion throughout the running world.

A fast race, a costly administrative error, and a debate that may linger long after the finish-line tape has been packed away.

The men's 100 metres at the 2026 Rome Diamond League is shaping up to be one of the most anticipated sprint races of the season, with an exceptional field featuring some of the fastest men in the world.

Scheduled for Thursday, June 4, at the iconic Stadio Olimpico in Rome, the race will bring together reigning stars, established champions and emerging talents in a contest that promises fireworks from the moment the gun goes off.

Kenya's Ferdinand Omanyala headlines a world-class lineup that includes American sprint sensation Noah Lyles, Botswana's Olympic champion Letsile Tebogo, Jamaica's explosive Ackeem Blake, South Africa's ever-consistent Akani Simbine and Italy's hometown hero Lamont Marcell Jacobs. With personal bests ranging from 9.77 to 9.97 seconds, the field is packed with athletes capable of producing something special on the Diamond League stage.

Omanyala, the African record holder with a blistering personal best of 9.77 seconds, arrives in Rome eager to continue his strong early-season form and prove he can challenge the very best on the global circuit. The Kenyan star has built a reputation as one of the fastest starters in world sprinting and will be looking to make a statement against an elite field.

Standing in his way is world champion Noah Lyles, whose personal best of 9.79 seconds places him among the fastest athletes in history. The American remains one of the sport's biggest attractions and will be determined to add another Diamond League victory to his impressive résumé.

The race also marks a major test for Olympic champion Letsile Tebogo. The Botswanan star has rapidly become one of athletics' most exciting talents, while Ackeem Blake continues to establish himself as a serious contender on the international sprint scene.

Adding further intrigue is the presence of Italy's Lamont Marcell Jacobs. Competing on home soil, the Tokyo Olympic champion will enjoy passionate local support as he seeks to deliver a memorable performance in front of the Roman crowd.

South Africa's Akani Simbine, Cameroon's Emmanuel Eseme, Great Britain's Jeremiah Azu and rising American talent Jordan Anthony complete a field that boasts remarkable depth and quality.

Audrey Werro announced her arrival as one of the early stars of the 2026 outdoor season with a commanding victory in the women’s 800 metres at the Rabat Diamond League, producing a performance that exceeded even her own expectations.

The Swiss middle-distance talent surged to victory in a brilliant 1:56.56, breaking the meeting record and delivering one of the fastest times recorded worldwide this season. In a race packed with quality, Werro displayed exceptional composure, confidence, and finishing strength to separate herself from the field and stamp her authority on the event.

What made the performance even more remarkable was the athlete's surprise at the level she had already reached so early in the campaign.

"I was not expecting such a strong start to the season," Werro admitted after the race.

The race unfolded at a relentless pace, but Werro remained perfectly positioned throughout. As the athletes approached the bell lap, she glanced at the clock and immediately sensed something special was within reach.

"When I saw the time at the bell, I felt really confident," she said. "I'm really happy with the Meeting Record and looking forward to the rest of the season."

Her confidence proved justified. Maintaining her rhythm over the final 400 metres, Werro powered down the home straight to secure the victory and rewrite the Rabat meeting record books in the process.

The performance sends an early warning to her rivals ahead of a season that promises major championships and high-profile Diamond League battles. Beyond the record-breaking time, Werro's display highlighted her growing maturity as a racer, combining tactical awareness with impressive speed and endurance.

With the outdoor season only beginning, the 1:56.56 clocking suggests that even faster times could be on the horizon. If Rabat is any indication, Audrey Werro may be poised for the biggest season of her career.

Her emphatic victory in Morocco was more than just another Diamond League win—it was a statement of intent from an athlete determined to challenge the world's best throughout 2026.

The city of Boston is set to welcome back one of its most celebrated champions as Kenya’s Sharon Lokedi headlines a world-class field for the 2026 B.A.A. 10K presented by Mass General Brigham Cancer Institute on June 21.

Fresh from another remarkable victory at the Boston Marathon in April, Lokedi returns to the streets of Boston and Cambridge carrying both momentum and confidence as she aims to defend the title she captured in dominant fashion last year.

The two-time Boston Marathon champion has developed a special connection with the historic race city. In 2025, she produced a course-record performance of 2:17:22 to win the Boston Marathon before returning this year to claim another victory in 2:18:51, the second-fastest winning time in the event’s storied history. Her success has cemented her status as one of the premier road runners in the world.

Lokedi will be making her first competitive appearance since her marathon triumph and arrives as the reigning B.A.A. 10K champion after clocking 31:39 over the challenging 6.2-mile course in 2025.

“Boston has become a very special place for me,” Lokedi said ahead of the race. “The atmosphere created by the fans and the community is unlike anywhere else. I’m excited to return and give everything I have to defend my title.”

The women’s race promises to be highly competitive. American Olympian Rachel Smith, who finished second at the Boston 5K in April, leads the domestic challenge. Kenya’s strong contingent includes African 10,000m champion Gladys Kwamboka, former B.A.A. 10K runner-up Stacy Ndiwa, and experienced road racer Viola Cheptoo. British Olympian Jessica Warner-Judd adds further international depth to a field packed with proven performers.

The men’s race is equally impressive, featuring elite athletes from 13 nations.

Ethiopia’s Dawit Seare enters as one of the leading contenders after capturing the 2025 Boston 5K title and bringing the fastest 10K personal best in the field at 27:21. Kenya will be represented by an accomplished group led by Alexander Mutiso, winner of the 2024 London Marathon and runner-up at last year’s New York City Marathon.

Patrick Kiprop also arrives in outstanding form after securing victory at the prestigious BolderBoulder 10K on Memorial Day, while Alex Masai returns looking to continue his strong record in Boston. Masai recently finished ninth at the Boston Marathon and has earned three top-ten finishes at the B.A.A. 10K.

Among the international stars making their mark is South Africa’s Adriaan Wildschutt, who makes his race debut after an impressive season highlighted by victory at the NYC Half Marathon in 59:30. Ethiopia’s Olympic bronze medallist Hagos Gebrhiwet adds further quality to the field, bringing a wealth of championship experience and previous success in Boston.

Canadian national 10K champion Andrew Alexander, two-time U.S. Olympian Hillary Bor, marathon standout Ryan Ford, and reigning USA 25K champion Andrew Colley complete a field stacked with talent and depth.

With defending champions, Olympic finalists, national champions and rising stars all converging on Boston, the 2026 B.A.A. 10K is shaping up to be one of the most competitive editions in recent memory. For Sharon Lokedi, however, the mission is simple: return to the city where she has repeatedly excelled and add another memorable chapter to her growing Boston legacy.
