Drinking water, especially in summer, helps us stay hydrated; however, drinking excessive water can trigger asthma. Although asthma can be triggered by allergens, pollen, and other factors, water can also play a role in triggering it. Tap to know how!

Increased Mucus Production

Drinking excessive amounts of water can increase mucus production in the body leading to congestion.

Increased Risk Of Aspiration

When we drink water too quickly or while laying down, the water can go down through the airway, increasing the risk of aspiration.

Pressure on Lungs

Sometimes when we drink water too quickly, it can cause the stomach to bloat that can put pressure on the lungs, making it difficult to breathe.

Hyponatremia

Drinking excessive water can lead to hyponatremia (low levels of sodium in the body), which can cause muscle weakness, fatigue, and can worsen asthma.

Disrupt Breathing Patterns

Drinking too much water can disrupt breathing patterns by causing a feeling of fullness and discomfort.
