Seasonal cough and coldWhenever the weather changes, the number of coughing visitors received by local health clinics and physicians increases. Whether it's the cold spells, pouring rains or hot and humid summers, respiratory viruses and allergies never leave a single opportunity to infect us. Moreover, things like changes in immunity, changes in our eating habits and poor hygiene can make us even more susceptible to infections and increase our chances of falling sick.

1. As the winter sets in, days become shorter. This reduces our exposure to direct sunlight. Lack of exposure to sunlight can cause Vitamin D deficiency which can weaken our immune system. Because the defence mechanism of the immune system is affected, viruses can survive, grow and multiply in our body for a longer period of time. Try these natural remedies to boost your immune system.

2. The dry and cold air during winters can dry out the nasal passage and simply irritate the throat and lungs causing cough. Some people even experience breathing problems due to blockage of nasal passages. This is called as cold-induced asthma which can also irritate the protective linings of nose and throat, triggering cough.

3. During summers, the wind is hot and you tend to sweat a lot. The chances of respiratory allergies and infections increase due to dust particles and sweat, triggering sore throat and dry cough. Breathing is naturally affected because of congestion, especially in crowded spaces.

4. Cough due to allergies caused by breathing smoggy air is very common during summers. This is because smog contains a pollutant called ozone which directly attacks the lung function. It causes inflammation of the protective linings of the lungs and also triggers asthma. Coughing due to smog is often painful because of constant uneasiness in the chest and throat.

5. Cough triggered during summers doesn't go away easily because of how you naturally react to weather changes. For example, during winters you tend to keep yourself warm, rest a lot and drink hot liquids which help you to recover fast. But during summers, you drink chilled water and summer beverages which increase the chances of cold infection or may even worsen your gastroesophageal reflux diseases (GERD) causing cough.

6. Rainy season is the most notorious season where spread of common cold and flu is the fastest. Common cold during this season comes along with headache and sore throat. Other symptoms like runny nose and nasal congestion also accompany cough due to the damp weather.

7. In the monsoon, the chances of pneumonia also increase, especially in people who have lung problems. Because of unpredictable rains, many people get completely drenched when it pours heavily. Therefore, the chances of recurring cold and cough are highest during rainy season. Refer to our monsoon health guide to keep allergies and infections at bay.

8. The worst part is that coughing is no longer only dependent on just seasonal changes. Looking at the erratic climate changes taking place daily, people with a healthy immune system also catch up respiratory infections.

9. During monsoons, after a heavy rainfall sometimes the climate turns really hot. Similar climate changes are seen in winters and summers as well. These drastic changes add to the factors that can trigger cough due to infections, allergies and breathing problems.

10. Apart from these day to day climate changes that cannot be controlled by us, we unknowingly subject ourselves to drastic and extreme temperature variations every day. Changes like exposure to constant air conditioned environment for a long period of time followed by stepping outdoors in hot, humid weather can also trigger respiratory problems causing cough.Read more about dry and wet the different kinds of cough
