As the monsoon season gradually gives way to cooler weather, fluctuations in temperature and humidity can affect the way our respiratory system feels. Some people may notice a dry or irritated throat, mild cough, hoarseness or a blocked nose soon after waking up.

While these symptoms are often temporary, they can sometimes be linked to allergies, respiratory infections, dehydration, acid reflux or the air inside your bedroom.

Why Does Your Throat Feel Dry in the Morning?

One common reason is breathing through the mouth while sleeping. If your nose is blocked because of allergies, a cold or nasal congestion, you may naturally breathe through your mouth. This allows more moisture to escape from the throat and can leave it feeling dry or irritated when you wake up.

The air inside the room can also make a difference. Air conditioners, fans and low-humidity environments may dry out the air, increasing throat irritation.

Changes in temperature and humidity can also trigger nasal allergies in some people. Increased exposure to dust, pollen, mould or other allergens can cause post-nasal drip, in which mucus moves down the back of the throat and triggers coughing.

Why Does the Cough Often Appear After Waking Up?

Mucus and secretions can accumulate in the airways while you sleep. When you get up in the morning, clearing your throat and moving around can trigger coughing.

Post-nasal drip can have a similar effect. During the night, mucus from the nose can drain towards the throat, causing irritation and a cough after waking.

Acid reflux is another possible cause. Stomach acid can sometimes move upward while lying down and irritate the throat, potentially causing morning cough, throat clearing or hoarseness.

Therefore, a morning cough is not necessarily caused by a change in weather alone.

How Can You Get Relief?

For mild throat dryness or irritation, simple measures may help:

• Drink sufficient water throughout the day.

• Try warm or room-temperature fluids if they feel soothing.

• Keep your bedroom comfortably ventilated.

• Avoid exposure to cigarette smoke, dust and other irritants.

• If you have nasal congestion, addressing the underlying cause may reduce mouth breathing.

• If reflux is a problem, avoid heavy meals close to bedtime and consider discussing recurring symptoms with a doctor.

Steam inhalation may feel soothing for some people, but it is not a cure for infections and very hot steam can cause burns. If you use steam, take care to avoid excessively hot water.

Pay Attention to Persistent Symptoms

A mild cough or dry throat that appears occasionally may not be a cause for concern. However, persistent or worsening symptoms deserve attention.

Seek medical advice if you develop difficulty breathing, chest pain, high or persistent fever, coughing up blood, significant weakness, or a cough that does not improve.

What Should You Eat During Changing Weather?

There is no single food that can prevent seasonal infections, but a balanced diet supports normal immune function.

Include fresh fruits and vegetables, adequate protein, whole grains and sufficient fluids in your diet. Foods such as ginger, garlic and turmeric can be part of a healthy diet, but they should not be considered substitutes for medical treatment.

Most importantly, maintain good sleep, stay hydrated and pay attention to indoor air quality. If your morning cough keeps returning, identifying the underlying cause—such as allergies, nasal congestion, reflux or an infection—is more useful than simply blaming the weather.
