The Monsoon Underdrinking Problem

During monsoon, three factors converge to cause underdrinking. First, cooler ambient temperatures (typically 25–32°C) suppress the thirst sensation compared to the 42–48°C summer conditions. Second, high humidity means sweat doesn't evaporate quickly, creating the perception that you're not losing fluid even when you are. Third, the overcast sky and cooler feel makes people psychologically feel less need for hydration. The result is chronic mild dehydration throughout the monsoon months.

What Actually Works

Switching to warm or hot drinks during monsoon addresses both the hydration gap and the seasonal comfort preference. Hot tea, warm water with ginger, hot soups, and warm water all count toward daily fluid intake and are naturally more appealing than cold water when it's raining. An insulated tumbler (ChillSip or DailySip) keeps tea hot for up to 6 hours.

💡 Monsoon Hydration Signals

In monsoon, the urine colour check is more important than in summer: dark yellow urine in the morning indicates underhydration that thirst didn't signal. Aim for pale yellow throughout the day. If you're spending long periods outdoors in rain: factor in the physical activity regardless of the cool temperature.
