Can Dirty Windows Affect Your Health?

We look at the impact of dirty windows on your health

Internal window cleaning

The mouldy bits


Mould loves a moist, warm place to call home and the condensation on your windows creates the perfect atmosphere for mould to survive and grow.


Look out for any dark brown/black spots or stains on the window/windowsills, these are all indicators you are growing mould on your office windows. Mould from the windows can cause respiratory infections and can make allergies worse, therefore you need to find a successful way to eliminate the bacteria. 


In some cases, mould can be undetectable, if it is growing through the inner part of the window. This can be hard to remove yourself and requires a professional cleaning company.


Using a cleaning service that specialises in window cleaning is the most efficient way to remove mould from the window, making your offices a safe and hygienic environment to work in.


Reducing all the allergens


Dirt and debris build up quickly on windows and windowsills and can be a larger health risk than you would imagine.


Dust, hair, skin, pollen etc. all gather on and around your windows and cause this range of allergic reactions:

  • Headache
  • Itchy eyes
  • Coughing 
  • Nausea 
  • Fatigue 
  • Runny nose 

 

These reactions clearly indicate the importance of keeping your office windows clean.


Getting those windows cleaned may even reduce the number of employees going off sick.


Let the (UV) light in


Research has shown that rooms with windows that allow a good amount of UV light in, have reduced amounts of bacteria and virus' floating around. Dirty windows can reduce the amount of natural light by around 40%.


Poor lighting in the office can affect the health of your employees, causing symptoms like:

  • Eye strain 
  • Migraines 
  • Headaches 
  • Lethargy 
  • Poor concentration

 

"Significant numbers of employees are frustrated by their lighting environment and are impacted by the negative effects. 48% have experienced eye strain or eye irritation due to lighting issues and 40% also reported tiredness, all due to poor lighting." Source: workplaceinsight.net

Commercial cleaning companies such as It’s Clean, are the best solution for this cleaning challenge, as they have the right chemicals and methods to eliminate any harmful bacteria and fungi from the window, that could be having a negative impact on office staff.
