The harm of excessive carbon dioxide to human health

**Excessive carbon dioxide: an invisible health killer**

Carbon dioxide, a common gas in our daily lives, can pose a serious threat to our health when its concentration exceeds the standard.

**Affects breathing**

Excessive carbon dioxide levels will first affect our respiratory system.  High concentrations of carbon dioxide can cause a relative decrease in oxygen content in the air, leading to hypoxia in the human body.  Long term exposure to this environment can cause people to experience difficulty breathing, dizziness, fatigue, and in severe cases, even the risk of suffocation.

**Cardiovascular system damage**

Excessive carbon dioxide can also cause damage to the cardiovascular system.  In a state of hypoxia, the heart needs to work harder to maintain normal blood circulation in the body, which may increase the burden on the heart and in the long run, may lead to cardiovascular diseases such as heart disease and hypertension.

**The nervous system is affected**

Excessive carbon dioxide may also cause damage to the nervous system.  In a state of hypoxia, the function of the brain may be affected, leading to problems such as lack of concentration, decreased memory, and delayed thinking.  For children, long-term hypoxia may also affect their intellectual development.

**Affects physical health**

Long term exposure to excessive carbon dioxide levels can lead to a decline in the body's immune system and susceptibility to various diseases.  In addition, hypoxia may also affect the body's metabolic processes, leading to various discomfort symptoms such as headaches, fatigue, nausea, etc.

**Protect the environment, stay away from excessive carbon dioxide, and always pay attention to whether the carbon dioxide around us exceeds the standard**

For the sake of our health, we need to actively take measures to reduce carbon dioxide emissions and protect the environment.  We can choose to use clean energy, reduce the use of fossil fuels, and increase greenery to reduce carbon dioxide emissions.  At the same time, we can also choose a well ventilated living environment to avoid prolonged exposure to enclosed and carbon dioxide exceeding standards.

Let's jointly pay attention to the issue of excessive carbon dioxide, protect our health, and safeguard our beautiful home!
