How to Avoid Getting Sick in Autumn: A Practical Guide for Teams
Shorter days, cooler air and more time indoors: autumn is great until the coughs and colds start doing the rounds. The good news is that a few simple, well-established habits lower the risk for you and your team. This guide covers how to avoid getting sick in autumn with everyday layers: clean hands, cleaner indoor air, the right humidity, sleep, movement and workplace norms that make staying home when sick easy.

Your autumn health playbook at a glance
| Layer | What to do |
|---|---|
| Hand hygiene | Wash with soap and water for about 20 seconds, or use a sanitizer with at least 60% alcohol (CDC) |
| Cough etiquette | Cough or sneeze into a tissue or your elbow, then clean your hands (CDC) |
| Cleaner air | Bring in outdoor air and filter the air you have |
| Humidity | Keep indoor relative humidity around 30 to 50% (US EPA) |
| Sleep and movement | 7 to 9 hours of sleep and regular activity, even in short bouts |
| When sick | Stay home, and ease back in with extra precautions |
Why the risk rises in autumn
As the days shorten, people spend more time indoors, where respiratory viruses spread more easily through shared air, especially in crowded or poorly ventilated rooms. Cooler, drier air plays a part too. That's why the most useful habits target both the air you share and your body's own defenses.
Everyday prevention that works
1. Hand hygiene
- Wash with soap and water for at least 20 seconds, including the backs of your hands, between your fingers and under your nails.
- No sink? Use hand sanitizer with at least 60% alcohol.
- Key moments: before eating, after the bathroom, after coughing or sneezing, and after public transport.
2. Stay home when you're ill
Current CDC guidance for respiratory viruses is to stay home while you have symptoms and return once you've been fever-free for 24 hours without medication and your symptoms are improving, then take extra precautions for the next few days, such as better ventilation, hand hygiene and distance.
3. Masks as an optional layer
A well-fitting, high-quality mask is a useful extra layer in crowded indoor spaces or when you or someone in your household is at higher risk. Keep workplaces mask-friendly rather than mask-mandatory.
4. Seasonal vaccines
Check your national health authority for current guidance on seasonal vaccines such as flu, including timing and eligibility. Some employers offer on-site or subsidized flu shots.
Cleaner indoor air: the quiet superpower
- Ventilate: bring in outdoor air mechanically or by opening windows when practical, and run kitchen and bathroom exhaust fans.
- Filter: upgrade HVAC filters where the system allows (for example MERV-13) and add portable HEPA air cleaners to meeting rooms and bedrooms. In a CDC simulation, portable HEPA cleaners reduced exposure to exhaled aerosols in a meeting room (CDC MMWR, 2021).
- Aim for 5: CDC recommends aiming for at least 5 air changes per hour of clean air in occupied rooms, combining ventilation, filtration and air cleaners (CDC).
Humidity and mold: keep it in the sweet spot
- Keep relative humidity around 30 to 50%. Too dry irritates airways; too damp encourages mold.
- A cheap hygrometer tells you where you are; humidify or dehumidify as needed.
- Fix leaks promptly and dry wet areas within 24 to 48 hours to prevent mold growth.
Lifestyle habits that support your immune defenses
1. Sleep
In an experimental study, people who slept six hours or less a night were more than four times as likely to develop a cold after being exposed to the virus than those who slept more than seven (Prather et al., Sleep, 2015). Aim for 7 to 9 hours on a consistent schedule. For practical tips, see bedtime rituals for better sleep.
2. Regular movement
A 2021 meta-analysis in Sports Medicine (Chastin et al.) found that people who are regularly physically active have a lower risk of community-acquired infections. You don't need long sessions: aim for 150 minutes of moderate activity a week plus two strength sessions, in bouts of any length. See 10 hacks to stay active in fall.
3. Nutrition, hydration and vitamin D
Balanced meals, plenty of plants and steady hydration support energy through the season; see hydration at work. Where sunlight is limited, the NHS advises considering a daily 10 microgram (400 IU) vitamin D supplement in autumn and winter (NHS). Guidance varies by country, so ask your doctor what's right for you.
Autumn allergies
- Ragweed pollen peaks from late summer into early autumn and can last until the first frost. Keep windows closed on high-pollen days and rinse off before bed.
- Mold thrives in damp leaves, basements and bathrooms. Control moisture and consider a HEPA air cleaner in the bedroom if symptoms flare.
Testing and early treatment
- COVID-19: if you're at higher risk and test positive, talk to a clinician quickly. Antiviral treatment needs to start within 5 to 7 days of symptoms, depending on the medicine (CDC).
- Flu: antivirals work best when started as early as possible, ideally within 48 hours of symptoms, especially for people at higher risk of complications.
- Testing: home antigen tests are convenient; repeating a test after a negative result improves detection.
If you feel something coming on: rest, hydrate, test early and skip intense training.
Workplace policies that reduce outbreaks
- Make staying home when sick easy. Support remote work for mild symptoms and don't reward presenteeism. More in how to reduce sickness absence in the workplace.
- Improve the air. Better filters where possible, HEPA units in meeting rooms and ventilation between sessions.
- Make hygiene easy. Sanitizer and tissues in shared spaces, with friendly signage.
- Support healthy habits. A four-week "Autumn Moves" challenge with an exercise minutes goal (for example 150 minutes a week) and bonus points for outdoor time keeps people active through the season.
A four-week autumn health plan
| Week | Focus | Actions |
|---|---|---|
| 1 | Air and habits | Pick two or three rooms to ventilate and filter; take a 10-minute daylight walk after lunch three times |
| 2 | Sleep and movement | Consistent bed and wake times for 7 to 9 hours; 150 active minutes in any mix of short bouts |
| 3 | Humidity and mold | Check humidity in key rooms (30 to 50%); fix leaks and dry wet areas quickly |
| 4 | Ready for illness | Stock a few home tests, know where to get care quickly, and agree stay-home norms with your team |
Frequently asked questions
1. Does a portable HEPA air cleaner actually help?
Yes, as a supplement to ventilation. In controlled CDC simulations, portable HEPA cleaners reduced exposure to exhaled aerosols in a meeting room setup.
2. How short can a workout be and still count?
Very short bouts add up toward weekly targets. Consistency matters more than session length.
3. Why does humidity matter?
Air that's too dry irritates airways, and air that's too humid encourages mold. 30 to 50% is a practical target for homes and offices.
The takeaway
Getting through autumn healthy doesn't require anything complicated. Focus on clean hands and cleaner air, comfortable humidity, good sleep and regular movement, and make staying home when sick the norm. Want to keep your team active and healthy through the season? Book a YuMuuv demo.
