What Causes a Dry Cough?

Dry cough, either brought on by seasonal allergies or asthma, is caused by swelling or irritation of the airways. Allergens that can trigger a dry cough include:

  • Dust
  • Pet Dandruff
  • Mold
  • Vermin Droppings

These allergens become more abundant during the spring and can trigger seasonal allergies, which often cause coughing.

Cold air can also trigger a dry cough by causing the airway to contract and tighten. Because cold air contains less moisture than warm air, prolonged exposure works to dry out the airways.

Best Home Temperature to Help Seasonal Allergies

As summer approaches and more people turn on their air conditioners, it’s important to be mindful of the optimal temperature to keep your home at to limit the onset of a dry cough.

Hot, humid homes can breed dust mites and mold, but cold air can also tighten the airways and trigger a cough. It’s a balancing act.

Make sure you keep your thermostat between 70 and 72 degrees to ensure your home does not get too hot but also that gusts from your air conditioning system don’t dry out your throat and trigger a dry cough. Best of all, by adjusting your indoor temperature, you can also reduce your energy costs – a win-win for all homeowners.

A Humidifier May Help

If you still find yourself suffering from a dry cough even after lowering your AC, consider investing in a humidifier for your home or for the rooms in which you spend the most time.

Humidifiers work by releasing water vapor into the air to increase overall moisture levels within a home. Humidity in your house should be between 30%-50%, and investing in a humidifier can help relieve symptoms of a dry cough and increase your level of comfort during allergy season.

There are different types of humidifiers available, depending on your needs and your budget, these are:

  • Central Humidifiers (built into the home’s heating and cooling system)
  • Evaporator (blows air through a wet wick)
  • Steam Vaporizer

Dry air makes mucus buildup in the lungs worse, which can be extremely dangerous as many viruses trigger respiratory problems. It’s important to keep the lungs healthy. Humidifiers will not cure a cold but can be a solution for a non-viral cough.
