Rare ‘Warm Night’ Warning Issued for 3 States Today: Why 32°C Midnight Heat Is More Dangerous Than the Daytime Sun
North Indian meteorologists have issued “warm night” warnings due to the fact that nighttime temperatures remain at dangerously high levels even after dark. Midnight temperatures in some places, for example, in parts of Delhi, Rajasthan, and Uttar Pradesh, are already close to 32°C, meaning that there is nearly no relief from extremely high daytime heat.
Health experts warn that warm nights may actually be a greater danger to human beings than hot daytimes since human beings lose a natural opportunity to recover from the heat of the day when they cannot cool down in the evening.
What Is a ‘Warm Night’ Warning?
A “warm night” warning is issued when the minimum temperature remains exceedingly above the normal temperature and cannot drop to a safe level after the sun sets.
Under normal circumstances, nighttime temperatures should allow the human body to recover from the heat of the day. However, during warm night situations:
- Your body continues to lose fluid overnight;
- Your heart rate continues to remain elevated for a longer period of time;
- Heat continues to be retained and released from indoor spaces throughout the duration of the night;
- Your ability to sleep is dramatically decreased.
Why Cities Stay Hot After Dark
Many of the major cities in India are experiencing the impact of urban heat islands. Concrete streets and buildings, automobiles, and the exhaust from air-conditioning systems trap and release heat back into the air at various intervals over the course of the night, which prevents the temperature from decreasing to its normal level during the night.
Final Words
Heater night warning signs in northern India illustrate yet another example of today’s modern heat waves – the danger never abates with the passing of daylight hours.
The health risks associated with prolonged heat exposure throughout the night have now become major public health concerns. For many cities, the failure of nights to provide sufficient cooling during those late evening hours can expose individuals to much greater risk of harm than the sun.
