This may seem quite obvious- especially if you frequently read our cleaning blogs- but cleaning has a huge impact on health! This is most significant for those with underlying conditions present; for example respiratory conditions such as asthma or emphysema. Lack of cleaning can lead to some nasty things forming- such as mould in different areas of your home. Mould is a pretty dangerous thing to have in your home- it can produce substances varying from irritants and allergens, to toxic substances! You can read more about the dangers of damp and mould here.
You may also be affected by other irritants and allergens such as dust. Again, this is worse for those with respiratory conditions but can affect anyone- especially if you are exposed to it for long periods of time (which of course, you would be if you didn’t clean your home at all).
Chances of infection also increase, for example if you accidentally cut yourself on a dirty cabinet: not only have you introduced dirt to your body whilst cutting yourself, but leaving your wound exposed to all the dirt in your home would hugely increase the risk of infection!
