Allergic Rhinitis: Characterized by frequent sneezing, stuffy nose, runny nose, itchy eyes, and post-nasal drip, allergic rhinitis is an inflammatory condition of the mucus membrane inside the nose. It is caused by viruses, bacteria, and allergens. Some of the external triggers of allergic rhinitis include humidity 3 chemicals, and air pollution (indoor or outdoor) etc.
Skin diseases: Most of the skin infections are caused by fungus. Fungal spores are the causal agent of these diseases. To understand more, click here 4 .
Migraine:One of the most common triggers of migraine is the weather. Whenever there is high (or low) humidity, there is a change in the oxygen levels in the air. The air becomes saturated with moisture in high humidity conditions reducing oxygen levels significantly. As a result, it
becomes difficult for the brain of the people with migraine to receive the right amount of oxygen to function properly. Result? – Unusual expansion or contraction of the blood vessels to compensate for the lack of oxygen, exerting tremendous pressure on the nerve fibres. Therefore, indoor humidity too may trigger a migraine 5 headache.
Depression:Dampness and growth of fungus in poorly ventilated homes have been long associated with depression 6. One should be careful about it before it takes the turn of clinical depression.

What are the reasons and how does damp wreaks havoc on our health?

1. Flourishing Pathogens

When you have damp in your home, it means excess moisture has been accumulated. Guess what, it is best for enabling pathogens and all kinds of germs to flourish and reproduce in higher numbers. Besides viruses and bacteria, other microorganisms like fungi and algae also proliferate in a moist environment. These microorganisms, being pathogenic, bring forth health disorders of various types. They release harmful chemicals in the air that pollute the indoor atmosphere or act as allergens causing mild to severe irritations in different parts of the body. If dampness persists these irritations tend to become chronic in nature.

2.Humid conditions make transmission faster

If multiplying by leaps and bounds was not enough, the transmission of viruses and bacteria and other microbes is facilitated in humid conditions. When you present them a humid indoor environment, they tend to spread exponentially.

Look at what’s happening in the current pandemic situation! Earlier it was said that COVID-19 can flourish only in cold climates. But more recent evidence shows that it can be transmitted in all areas including hot and humid places 1. Actually, virus thrives inside the human body the normal temperature of which is 36.5-degree to 37-degree Celsius. This is regardless of the external temperature and weather conditions. So, apart from maintaining basic hygiene, it is advisable to keep your house as damp-free as possible to restrict the transmission of viruses.

3. Flourishing dust mites

Dust mites are popular in households where the temperature is considerably high and the moisture level is also in excess. They are the catalyst to give rise to allergy, stuffy nose, respiratory problems and asthma. So, if you have experienced stuffy nose, itchy eyes, and breathing problem then you might want to look into the condition of your house. These symptoms can further give birth to health problems that

5. Cold climate

Several types of research have shown that a cold indoor climate is the result of dampness in those regions where it is not naturally cold outside. Unmaintained house, damaged roofs and walls are the common causes but it could also be because of the lack of proper ventilation. Humans can stay overall healthy if the environment in which he or she is living is dry with optimum moisture content in the air. If
the house becomes a place where it is difficult to breathe then it is obvious that the environment isn’t right.

Cold indoor atmosphere adversely affects respiratory health. A significant number of people in the world suffer from asthma 2 which is often linked with damp indoors. Chronic coughing, wheezing, breathing difficulty are the health problems which lead a person towards asthma. And asthma could be life-threatening. It just gets worse if not treated in the right way with the right amount of attention.
