In a report by Glamour UK, physician and immunologist Dr. Farah Latif said annual flu vaccination is one of the most effective ways to reduce influenza risk and the chance of serious illness. She also recommended sleep, a balanced diet, exercise, stress management and hygiene, while cautioning that supplements and wearable devices are not guaranteed protection.
Physician and immunologist Dr. Farah Latif told Glamour UK that the most reliable ways to lower flu risk are to get the annual flu vaccine when eligible and maintain everyday habits that support normal immune function. Her advice also highlights hand hygiene and ventilation, while warning that supplements and wearable health devices should not be treated as proven ways to prevent influenza.
Latif, a physician and clinical academic with more than 15 years of NHS experience and a PhD in immunology, said there is no single intervention that guarantees a person will avoid flu. She recommended adequate sleep, a balanced diet, regular exercise and stress management as ongoing habits that can affect how the immune system responds to infection. These measures support general health; the source does not claim they make anyone immune to influenza.
Latif called the annual flu vaccine one of the most effective ways to reduce the risk of influenza and, if infection occurs, the likelihood of becoming seriously unwell. The report does not provide vaccine effectiveness figures or specify eligibility rules, which can vary by location and season. Readers should check current guidance from their local health authority or clinician.
She said vitamin D is important for normal immune function and that correcting a genuine deficiency may be worthwhile. But taking extra vitamin D when levels are already sufficient has not consistently been shown to prevent flu, according to Latif. She also said vitamin C and zinc have roles in immune function, while evidence that supplements prevent influenza in otherwise healthy people is limited. Her advice was to prioritize food and consider supplements for a demonstrated deficiency or dietary need rather than taking high doses in hopes of avoiding illness.
Vaccination Outweighs Quick Fixes
The advice matters because flu can cause serious illness, and people may mistake it for a more severe common cold. Latif’s account directs attention toward vaccination and practical prevention rather than promises of a single product or “biohack.” It also draws a distinction between supporting general immune function and proving that a measure prevents influenza: those are not the same claim.
That distinction is relevant to readers weighing supplements, wearables or lifestyle changes during flu season. The report offers no evidence that a tracker can prevent infection or that a nutrient supplement protects people who are not deficient. People with health conditions, questions about vaccine eligibility or concerns about supplements should seek advice from a qualified health professional.

Everyday Steps Alongside Vaccination
Latif also recommended measures intended to limit exposure and transmission. She advised washing hands with soap and water, particularly after being in public, and avoiding touching the eyes, nose and mouth with unwashed hands. Because flu can spread through the air, she suggested improving airflow by opening windows where possible and avoiding crowded, poorly ventilated spaces when feasible.
If someone nearby is unwell, Latif said keeping distance and wearing a well-fitting mask can offer additional protection. These are practical precautions, not a guarantee against infection. The source frames them as complementary to vaccination and other health habits, not as replacements.
The article also discusses wearable technology that tracks measures such as sleep and resting heart rate. Latif said devices may help users understand their general health and notice changes in their usual patterns. The supplied source text ends before giving further detail about this point, and it does not establish that wearables can diagnose flu or stop it.
“The best thing we can do is make sure our immune system is functioning as well as possible before we’re exposed to a virus.”
— Dr. Farah Latif, speaking to Glamour UK
Limits of the Prevention Evidence
The source report does not give clinical study data, vaccine effectiveness estimates, or a season and country to which its advice applies. It also does not quantify how much sleep, diet, exercise, ventilation or masking changes an individual’s risk. Latif’s comments are expert guidance as reported by Glamour UK, not a guarantee that any measure will prevent infection.
The supplied material cuts off during its discussion of wearable technology, so any additional claims or advice in the original article cannot be verified from the text provided. It is also unclear whether the article covered what to do after flu symptoms begin; the material supplied here focuses mainly on prevention.
Check Local Flu Guidance
Readers can check local public-health guidance for the current flu vaccine and eligibility information, and ask a clinician about personal risk, possible deficiencies or whether a supplement is appropriate. During flu season, handwashing, ventilation and avoiding close contact with people who are sick remain practical precautions described in the report. The source provides no specific upcoming study, policy decision or publication milestone.
Key Questions
Does the report say the flu vaccine prevents every infection?
No. Latif recommends annual vaccination as one of the most effective ways to reduce risk and the likelihood of serious illness, but the report does not say it guarantees protection.
Can vitamin D, vitamin C or zinc prevent flu?
The report does not establish that supplements prevent influenza in otherwise healthy people. Latif said correcting a genuine vitamin D deficiency may be worthwhile, but high doses should not be treated as a flu shield. Ask a health professional about individual needs.
What everyday steps did the immunologist recommend?
Latif named sleep, balanced eating, exercise and stress management, along with handwashing and improved airflow where possible. She also suggested distance and a well-fitting mask around someone who is ill.
Can a wearable device tell me I have the flu?
The supplied report says wearables can track measures such as sleep and resting heart rate and may flag changes in personal patterns. It does not establish that they diagnose flu or prevent infection.
