Sometimes your health matters more than manners
Each autumn, as temperatures fall and people draw closer together indoors, the ancient contest between human immunity and seasonal virus resumes. A UK pharmacist, drawing on years of watching this cycle unfold, offers a quiet reminder that resilience is not accidental — it is built, night by night and meal by meal, through choices that most of us already know but too easily defer. The wisdom here is not new, but its timing is perennial: preparation, not reaction, is the surest shelter against winter's familiar toll.
- Cold and flu season is not merely bad luck — crowded indoor spaces, dry air, and weakened winter immunity create ideal conditions for viruses to spread rapidly.
- High-touch surfaces like doorknobs, phone screens, and shopping trolleys harbour live viruses for up to 48 hours, turning everyday objects into silent transmission points.
- Sleep, nutrition, hydration, and targeted surface hygiene form the first line of defence — practical, unglamorous, and consistently underestimated.
- The flu vaccine requires a two-week window to build immunity, meaning delay is itself a risk, particularly for the elderly, pregnant women, and those with chronic conditions.
- Avoiding contact with unwell people — however socially awkward — remains the simplest and most direct way to interrupt transmission before it begins.
Winter brings a familiar rhythm: the cough on the commute, the colleague who came in anyway, the child who carried something home from school. Cold temperatures push people indoors and together, and the body's natural defences appear to weaken in the process — leaving viruses with an opening they are quick to exploit.
Amir Bhogal, director and superintendent pharmacist at Pyramid Pharmacy Group, has watched this pattern long enough to build a practical framework around it. It starts with sleep — seven to nine hours each night — not as comfort, but as biological infrastructure: the time your body uses to manufacture the antibodies that intercept viruses before they can take hold. Alongside sleep, a diet rich in fruits, vegetables, and lean proteins supplies the vitamins and minerals immunity depends on, while adequate hydration ensures those nutrients reach the cells that need them.
The second strategy is less inspiring but no less important: clean the surfaces that everyone touches. Doorknobs, phone screens, gym equipment, trolley handles — viruses can survive on these for up to two days. Bhogal recommends antibacterial wipes or sprays with at least 70 percent alcohol, and thorough handwashing upon arriving home. Changing into fresh indoor clothes adds another layer of protection, particularly for anyone in the household who is already vulnerable.
Third comes vaccination — and crucially, its timing. Because the flu jab takes around two weeks to generate immunity, waiting until December means arriving late to your own defence. Early booking is especially vital for the elderly, pregnant women, young children, and those managing chronic conditions, for whom influenza carries risks well beyond inconvenience.
The final step is the one most people resist: if someone is unwell, keep your distance. Virus-laden droplets travel several feet through the air, and shared space with an infected person carries real risk. Rescheduling is not rudeness — it is reason. The virus, Bhogal notes, has no interest in your social obligations.
Winter arrives and with it comes the familiar cycle: the cough on the train, the colleague who shouldn't have come to the office, the child who brings home something from school. Colds and flu spike when the temperature drops, and there are reasons for this beyond simple bad luck. People cluster indoors when it's cold, breathing the same air, touching the same surfaces. The bacteria that normally help protect us seem to struggle in winter's grip, leaving our immune systems less fortified against the viruses waiting to exploit that gap.
Amir Bhogal, who runs Pyramid Pharmacy Group as its director and superintendent pharmacist, has spent his career watching this pattern repeat. He's developed a framework for staying well through the season, and it begins with the basics: sleep and food. Seven to nine hours of uninterrupted sleep each night gives your body time to repair itself and manufacture antibodies—the proteins that recognize and neutralize viruses before they can take hold. Sleep is not luxury; it's infrastructure. Pair that with a diet built on fruits, vegetables, and lean proteins, and you're supplying your cells with the vitamins and minerals they need to function properly and resist infection. Hydration matters too, especially when the air is dry and cold. Water helps nutrients move through your body efficiently, reaching the places where they're needed most.
The second strategy is less glamorous but equally practical: identify where germs accumulate and clean those places regularly. Doorknobs, phone screens, tabletops, shopping trolley handles, gym equipment—these are the surfaces that hundreds of hands touch every day. Viruses can survive on these surfaces for up to two days, waiting for the next person to touch them and then touch their face. Bhogal recommends keeping antibacterial wipes or spray with at least 70 percent alcohol nearby, ready to sanitize whatever you've just touched. When you get home, wash your hands thoroughly with antibacterial soap for at least twenty seconds, making sure to reach between your fingers and under your nails where germs hide. Better still, change your clothes when you arrive—fresh indoor clothing reduces the risk of carrying viruses into shared spaces where they might infect someone whose immune system is already compromised.
The third step is vaccination, and timing matters. The flu vaccine takes roughly two weeks to generate immunity in your body, which is why Bhogal urges people to book early rather than waiting until December when everyone else is scrambling. This is especially important for people in vulnerable groups: the elderly, pregnant women, young children, and anyone living with chronic conditions like asthma, diabetes, or heart disease. For these populations, the flu is not an inconvenience—it's a genuine threat. Making vaccination part of your annual routine is straightforward risk reduction.
The final recommendation might seem obvious but often feels awkward in practice: if someone is unwell, don't spend time with them. Politeness matters, but health matters more. Viruses travel in the microscopic droplets that spray out when someone coughs or sneezes, and those droplets can reach you from several feet away. Even breathing the same air as an infected person carries risk. Good ventilation and masks help, but the simplest solution is distance. Cancel the plans. Reschedule the meeting. The virus doesn't care about your manners, and neither should you when your health is on the line.

Getting at least 7-9 hours of uninterrupted sleep each night allows your body to repair itself and build a stronger antibody response— Amir Bhogal, director and superintendent pharmacist of Pyramid Pharmacy Group

The Hearth Conversation Another angle on the story
Why does winter make us more vulnerable? Is it just that we're indoors more?
That's part of it, yes—we're packed together in heated rooms, breathing recycled air. But there's something else happening. The bacteria that normally help protect us, the friendly ones in our microbiome, they seem to weaken when it's cold. So we lose some of our natural defense at the exact moment we're exposed to more viruses.
Seven to nine hours of sleep sounds like a lot. Is that really necessary?
It's not arbitrary. Sleep is when your body builds antibodies, when it repairs the damage from the day. You can't manufacture immunity while you're awake and stressed. That's the pharmacist's point—it's not indulgence, it's biology.
The hand-washing advice is familiar. What's new about the clothing change?
Most people don't think about it. You come home from the supermarket or the gym, you've touched dozens of surfaces, and then you sit on the couch or hug someone. Changing clothes is a simple barrier. It sounds fussy, but it works.
Why emphasize vaccination so early? Isn't it available all winter?
It is, but immunity takes two weeks to build. If you wait until November and then get sick in December, you've missed the window. For elderly people or pregnant women, that delay could mean the difference between a bad cold and a serious complication.
And the last point about avoiding sick people—that feels almost too simple.
It is simple. But people feel guilty canceling plans. The pharmacist is saying: don't. Your health comes first. The virus doesn't care about your social obligations.
