On July 1, 2021, Delhi experienced a heatwave, when the maximum
temperature rose to 43.5°C. At the same time, Ganganagar, in west Rajasthan,
reported India's highest temperature of 44.5°C. Some pockets of Punjab,
Haryana, Chandigarh, Delhi, north Rajasthan and west Uttar Pradesh still
continue to face heat wave conditions. This issue is now prevalent world over.
But the world is not only getting hotter but also more wetter or humid.
We usually consider the dry-bulb temperature to describe how hot or cold
a place is. Scientists, however, have been stressing upon taking into account
humidity and other factors to assess how weather conditions will affect human
health and activity. Humidity is measured as wet-bulb temperature. Factoring in
the humidity along with the heat, called the heat index, helps us determine
what the temperature actually ‘feels like’. You may have noticed this in your
mobile phones and apps as well. Humidity combined with heat is deadlier for
human health and wellbeing. Currently, one phenomenon is severely testing the
human tolerance of this heat-humidity balance. Climate Change!
Humans with their sweat-based cooling system, have been well-designed to
beat the heat. But there is a limit to the level of heat and humidity we can
cope with. A wet-bulb temperature or WBT of 35°C mark is considered the maximum
limit of humidity that humans can handle. Beyond this, the body can no longer
effectively cool itself via perspiration.

Electric power consumption
will be hardly reduced in the future. The more electrical devices – the more electricity required. Indeed, the price
we have to pay for our comfort, gets higher. However, some innovations are
aiding to save non-renewable sources to some extent. This video features the
smartest and the most original ones.
