State relative humidity and dew point precisely and explain why it matters in 2-3 sentences.

# Relative Humidity and Dew Point **Relative humidity** is the amount of water vapor currently in the air expressed as a percentage of the maximum amount the air could hold at that temperature. **Dew point** is the temperature to which air must be cooled for water vapor to condense into liquid water (dew, fog, or clouds). ## Why It Matters These measurements are crucial because they determine human comfort, weather forecasting accuracy, and numerous physical processes. High relative humidity impairs the body's ability to cool itself through sweat evaporation, making hot weather feel more oppressive, while dew point provides an absolute measure of moisture that indicates both comfort levels (dew points above 65°F/18°C feel muggy) and precipitation potential.
