Best Hygiene Habits to Avoid Infections

Best Hygiene Habits to Avoid Infections
Many common infections, from colds and flu to stomach bugs and skin infections, spread through hands, surfaces, food, water, and the air. Good hygiene breaks that chain. A few consistent habits can cut your risk of getting sick, and of passing infections to others, by a surprisingly large amount, and they cost almost nothing.
This guide explains the most effective hygiene habits, how and when to do them properly, which common hygiene myths to ignore, and how to adapt your routine for children, travel, and illness at home.
How Infections Spread
Germs reach you in a few main ways:
- Direct contact: Touching an infected person or their bodily fluids.
- Droplets and aerosols: Breathing in particles from someone’s cough, sneeze, or breath.
- Contaminated surfaces: Touching a doorknob, phone, or tap, and then your eyes, nose, or mouth.
- Food and water: Eating or drinking contaminated items.
- Insects and animals: Mosquito bites, ticks, and contact with pets or livestock.
Hygiene habits target each route.
1. Wash Your Hands Properly
Handwashing is the single most effective hygiene habit. It reduces the risk of diarrhoeal and respiratory infections significantly.
How to Do It
- Wet your hands with clean running water.
- Apply soap and lather well.
- Scrub all surfaces, including the backs of the hands, between the fingers, under the nails, and the thumbs, for at least 20 seconds.
- Rinse thoroughly.
- Dry with a clean towel or air dryer.
When to Wash
- Before eating or preparing food.
- After using the toilet or changing nappies.
- After coughing, sneezing, or blowing your nose.
- After touching animals, animal waste, or raw meat.
- After being in public places, using public transport, or touching shared surfaces.
- Before and after caring for someone who is sick.
- Before and after treating a wound.
If soap and water are not available, use a hand sanitiser containing at least 60 percent alcohol, covering all surfaces until dry. Sanitiser does not work as well on visibly dirty hands.
2. Cover Coughs and Sneezes
Cough or sneeze into a tissue or the crook of your elbow, not into your hands. Throw tissues away immediately and wash your hands. If you are unwell, wearing a mask around others can protect them, particularly in crowded or enclosed spaces.
3. Avoid Touching Your Face
Germs enter through the eyes, nose, and mouth. Try not to touch your face with unwashed hands, and keep your hands away from your eyes if you wear contact lenses until you have washed them.
4. Practise Food Safety
- Wash fruits and vegetables before eating them.
- Keep raw meat, poultry, and fish separate from ready-to-eat foods, with separate boards and knives.
- Cook meat, eggs, and fish thoroughly.
- Refrigerate leftovers promptly, and reheat them until steaming hot.
- Avoid unpasteurised milk and products.
- Check expiry dates, and discard food that smells or looks off.
- Keep kitchen surfaces, cloths, and sponges clean.
5. Drink Safe Water
Where water quality is uncertain, drink bottled, boiled, or filtered water, and use it for brushing teeth and washing food. Avoid ice of unknown origin.
6. Clean Frequently Touched Surfaces
Door handles, phones, keyboards, remote controls, taps, light switches, and kitchen counters can carry germs. Wipe them regularly with soap and water or a suitable disinfectant, particularly when someone in the home is ill.
7. Keep Personal Items Personal
Do not share towels, razors, toothbrushes, nail clippers, drinking cups, or utensils. Replace toothbrushes every three months, or after an illness.
8. Look After Cuts and Wounds
- Rinse minor cuts with clean running water.
- Cover them with a clean dressing and change it daily.
- Watch for redness that spreads, warmth, swelling, pus, or fever, which signal infection. Read the warning signs of serious infection.
9. Take Care of Your Teeth and Mouth
Brush twice a day, clean between your teeth daily, and see a dentist regularly. Gum disease and dental abscesses can lead to infections elsewhere in the body.
10. Keep Up With Vaccinations
Vaccines protect against many serious infections, including flu, hepatitis, tetanus, and pneumococcal disease. Ask your doctor which vaccines are recommended for your age and health.
11. Stay Home When You Are Sick
Resting at home helps you recover and stops you from spreading infection to colleagues, classmates, and vulnerable people. Return to normal activities when your fever has gone and you feel well enough.
12. Practise Safe Sex
Use condoms with new or casual partners, and get tested regularly if relevant.
13. Protect Yourself From Insect Bites
Use repellents, nets, and long clothing in areas with mosquito-borne diseases, and remove standing water around the home.
14. Support Your Body’s Defences
Hygiene works alongside your immune system. Eat a balanced diet, sleep well, exercise regularly, and manage stress. Learn how poor immunity increases infection risk and the natural ways to improve immune health.
Hygiene at Home and Work
- Keep bathrooms and kitchens clean, and disinfect toilets and sinks regularly.
- Wash bedding and towels weekly, or more often during illness, on a hot cycle where possible.
- Use separate bins and gloves for cleaning sickrooms.
- Clean shared desks, phones, and equipment at work.
- Ventilate rooms by opening windows.
Hygiene for Children
- Teach handwashing with songs or timers.
- Keep nails short.
- Wash toys regularly.
- Keep children home when they have a fever, vomiting, or diarrhoea.
- Make sure vaccinations are up to date.
Hygiene While Travelling
- Carry hand sanitiser and wipes.
- Drink bottled or treated water in areas where tap water may be unsafe.
- Eat freshly cooked, hot food, and avoid raw or undercooked items.
- Check recommended travel vaccines.
Common Hygiene Myths
- “Antibacterial soap is better.” Plain soap and water are just as effective for everyday use.
- “Being too clean weakens immunity.” Normal hygiene does not harm immunity. It prevents infections.
- “Hot water kills germs better when washing hands.” The temperature you can tolerate does not make a difference. Soap and scrubbing do.
- “The five-second rule makes dropped food safe.” Germs transfer instantly.
When to See a Doctor
See a doctor if you develop a fever lasting more than a few days, a wound that looks infected, persistent diarrhoea or vomiting, difficulty breathing, or any symptoms that worry you. Higher-risk groups, such as babies, older adults, pregnant women, and people with weakened immunity, should seek advice earlier.
Frequently Asked Questions
How often should I wash my hands?
Whenever they are visibly dirty and at key moments such as before eating, after the toilet, and after coughing or sneezing.
Is hand sanitiser as good as soap?
Alcohol-based sanitiser is effective for most germs when soap is unavailable, but washing is better when hands are dirty.
Do masks help?
They can reduce the spread of respiratory infections, particularly when worn by someone who is sick or in crowded spaces.
Final Thoughts
Good hygiene is simple and powerful. Wash your hands well, cover coughs and sneezes, keep food and water safe, clean frequently touched surfaces, care for wounds, and stay home when ill. Combined with vaccines and healthy lifestyle habits, these steps protect you and the people around you.
