Seasonal Workplace Hygiene: Low-Cost Strategies to Keep Staff Healthy

In our last article we looked at how cleanliness links directly to productivity and absenteeism. This time, we’re taking a step further: exploring practical, evidence-based ways businesses can reduce infections during peak cold, flu, and allergy seasons — without breaking the budget.

Why It Matters

Each year, viruses like flu, norovirus, and the common cold affect millions of workers. Studies show that a single contaminated surface — such as a door handle — can spread viral particles to half an office within hours. The result is avoidable sick days, reduced morale, and higher costs.

1. Hand Hygiene Interventions

Research confirms that simple hand hygiene campaigns can reduce workplace illness by up to 31%. Providing alcohol-based sanitiser, educational posters, and reminders near entrances, kitchens, and meeting rooms is inexpensive but highly effective.

2. Target High-Touch Surfaces

Door handles, light switches, telephones, and break-room surfaces are hotspots for germs. Targeted mid-day disinfection of these surfaces, combined with staff access to wipes, can reduce viral contamination by over 80%.

3. Improve Air Quality

Poorly maintained air conditioning can spread germs, while clean filters reduce risk. For enclosed offices, portable HEPA air purifiers have been shown to clear aerosols up to five times faster than HVAC systems alone — a low-cost solution with high impact.

4. Add Plants (With Care)

Indoor plants like peace lilies, spider plants, and snake plants can reduce pollutants such as formaldehyde and acetone, while also boosting staff wellbeing. However, be mindful of allergies — choose hypoallergenic species and avoid overwatering.

5. Support Vaccination

Seasonal flu vaccination remains one of the most cost-effective defences against absenteeism. Employers can encourage uptake by sharing information or offering workplace clinics during the winter months.

6. Encourage the Right Culture

A hygienic workplace isn’t just about cleaning; it’s about behaviour. Staff should feel supported to:

• Stay home when ill — reducing the risk of wider infection
• Report issues with ventilation or hygiene quickly
• Use hygiene facilities without stigma or judgement

The Takeaway

Seasonal hygiene doesn’t have to mean major spending. From sanitiser to plants, from portable filters to flu vaccination, there are simple steps that make a measurable difference. Combined with a professional cleaning contract, these low-cost interventions keep staff healthier, businesses more productive, and absenteeism down.
