How to Support Your Immunity in Winter: Foods, Habits and Supplements

Every winter the advice starts flying: eat this, take that, drink a special kehwa and you will never catch a cold. Shops and social media are full of products that promise to boost your immunity. The truth is simpler, and a little less exciting. No single pill makes you immune, but some everyday habits do help your body fight infections, and a few supplements have a modest role.

This guide explains what your immune system needs, which foods and habits help most in the Pakistani winter, what the evidence says about vitamin C, zinc and multivitamins, and who should see a doctor.

Can you really boost your immunity?

Your immune system is a network of cells, organs and proteins, not a single switch you can turn up. Having a stronger immune system is not always better either. What you can do is give it the conditions to work well: enough sleep, good food, movement and protection from avoidable germs.

Habits that matter most

• Sleep: adults need seven to nine hours. People who sleep badly catch more colds and recover slower.
• Hand washing: soap and water for twenty seconds, before eating and after coming home, prevents a large share of infections.
• Vaccines: the yearly flu shot and routine vaccines work better than any supplement. See our guide to flu season in Pakistan.
• Exercise: a brisk 30-minute walk on most days supports normal immune function.
• Stop smoking and avoid second-hand smoke. It damages the airways that protect you from germs.
• Manage stress, because long-term stress lowers the body’s defences.
• Keep warm and ventilated: dress in layers and air out rooms daily, so germs do not build up.

Winter foods that help

• Citrus and guava: malta, kinnow, oranges and especially guava (amrood) are rich in vitamin C. Amla is another strong source.
• Protein: eggs, chicken, fish, dal and chana provide the building blocks for immune cells.
• Zinc-rich foods: meat, chickpeas, pumpkin seeds, nuts and dairy.
• Yoghurt (dahi) and other fermented foods, which support healthy gut bacteria.
• Leafy greens and colourful vegetables: saag, carrots, tomatoes and peppers provide vitamins A, C and E.
• Warm fluids: soup, chicken broth and herbal drinks such as joshanda keep you hydrated and soothe the throat.
• Midday winter sun for fifteen to twenty minutes, to help your body make vitamin D. Read our guide to vitamin D deficiency in Pakistan.

What about supplements?

Vitamin C

Taking vitamin C regularly does not stop most people catching a cold, though it may shorten a cold slightly. It is most useful if your diet is short on fruit and vegetables. Options include Nutrify Immy C and Vitamin C Tablets Linear. Very large amounts can cause stomach upset and may raise the risk of kidney stones in some people.

Zinc

Zinc helps normal immune function, and some studies find that taking it early in a cold may shorten the illness. It can cause nausea and a metallic taste, and long-term high intake can lower copper levels. Products include Nutrify Zino Zinc and Nutrifactor Nuzinc.

Multivitamins

A multivitamin only fills gaps. It will not protect you if your diet is already good. If your meals are limited, Nutriwell Multivitamin for Men and Nutriwell Multivitamin for Women are everyday options.

Herbal drinks

Instant Joshanda Sachets are a traditional warm drink in Pakistani homes. They are comforting when you have a cold, although they do not prevent infection.

Cautions

• Check with your doctor or pharmacist before starting supplements if you are pregnant, breastfeeding, on regular medicines, or have kidney disease or a history of kidney stones.
• Avoid giving adult supplements to children. Ask your paediatrician.
• Be careful with products that promise to cure or prevent serious illness. Genuine supplements never promise that.
• More is not better. High doses of some vitamins and minerals are harmful.

When frequent infections need a check

• You or your child catch more than a few infections a year that are severe or slow to clear.
• Infections keep coming back in the same place, such as the ears, chest or skin.
• You have unexplained weight loss, night sweats, or tiredness that does not go away.
• You have diabetes, anaemia, or a long-term illness that may weaken your defences. Our guide on diabetes in Pakistan explains why blood sugar control matters.

Frequently asked questions

Does vitamin C prevent flu?

No. It may slightly shorten a cold in some people, but it is not a substitute for the flu vaccine or hand washing.

Is it safe to take supplements every day?

Standard multivitamin and vitamin C products are safe for most healthy adults at the dose on the pack. Check with your doctor if you take other medicines.

Do cold drinks and ice cream lower immunity?

No. Infections come from germs, not from cold food. But a cold drink can irritate an already sore throat.

What is the best immunity booster for kids?

Sleep, balanced meals, outdoor play, up-to-date vaccines and hand washing. Ask your paediatrician before any supplement.
