If only we had that power! That is not to take away from the importance of the issue of social housing, which I will touch on later. Let us be honest: many people go into the housing that their pockets allow. As a result, they end up in housing that is not particularly in the right category, the right condition or the right shape. The hon. Gentleman is right that the benefit cap also dictates where someone can go. I will give the Minister plenty of time to get her thoughts together on that. However, that is an important point, and I will touch on it later.
Poor indoor air quality has an annual cost to the UK of more than 204,000 healthy life years. It causes thousands of deaths per year, and gives rise to health costs in the order of tens of millions of pounds. One third of people in the United Kingdom suffer from mould in their homes and are at increased risk of respiratory problems, infections, allergies and asthma. Just last week, I saw three constituents with mould growth issues in their houses—mould not caused by condensation, but ingrained in the walls. Sometimes ensuring that the housing associations or housing executive take those issues on board is quite a job.
There are more than half a million overcrowded households. The issue affects one in 10 children—something we cannot ignore. Overcrowding is linked to health and development issues, including meningitis, respiratory conditions, slow growth rates, accidents in the home, stress, anxiety, depression and poor adult health. Occupants of poor-quality housing are more likely to suffer from restricted daylight and noise pollution.
We cannot ignore noise pollution. In the news this morning someone put forward the idea of building houses and flats over railway lines. I am not sure if any hon. Member saw that. The first thing that came to my mind was the noise of the trains continually going underneath. How could those homes be adapted to mitigate that? We need to address noise pollution. Natural light helps to improve the recovery times of long-stay patients and reduces anxiety and the need for medication. Noise pollution can cause long-term health issues and increase stress and the risk of cardiovascular effects.
It is clear that there is a lack of public awareness of these problems, and limited knowledge of the facts. Too often, the homes we live in are, in so many ways, causing or aggravating health problems.
