'My body can't take it': Brutal nighttime temperatures give Delhi residents little respite from India's searing heatwave

By Esha Mitra and Kathleen Magramo, CNN New Delhi (CNN) — Nights are getting uncomfortably and dangerously hotter in India’s capital as people in the world’s most populous nation feel little respite from unrelenting temperatures. Northern India has endured a scorching summer, with one part of Delhi reached 49.9 degrees Celsius (121.8 degrees Fahrenheit) in late May — the capital’s highest temperature on record. But the stifling heat persists even after the blazing sun has set. The city is cooling down by only 8.5 degrees Celsius at night compared to a 12.2 degrees cooling down in urban outskirt areas, a report published by the Centre for Science and Environment (CSE) last month tracking urban heat stress in Delhi has found.

The warmer nights deprive people of rest and recovery from long hours of exposure to oppressive heat, particularly for people without access to air conditioning. Bicycle rickshaw driver Sagar Mandal told CNN that he’s been getting fewer passengers because people opt for air-conditioned taxis over open-air transport. “My body can’t take it, but I have to keep cycling. We are used to physical labor, we aren’t complaining about that. But this heat is not normal, something has to change,” the 39-year-old, who pedals people around the city, said. “No one cares if we live or die, no matter who you vote for this is a problem no one can solve,” he said.

Hotter nights are a consequence of the climate crisis, scientists have warned, heightening the health hazards of heat stress. Studies have shown higher nighttime temperatures make it harder to fall asleep and reduce deep wave and REM (rapid eye movement), both critical to how well the body repairs and refreshes itself at night. In the United States, for example, nights are warming faster than days in most of country, the 2018 National Climate Assessment found. Mandal, the cycle-rickshaw driver said he has been sleeping on the roof of his home for some hope of cooler air but only for a couple of hours. “I barely sleep these days,” he said.

Brutal nighttime temperatures give Delhi residents little respite from India’s searing heatwave

NEW DELHI — Nights are getting uncomfortably and dangerously hotter in India’s capital as people in the world’s most populous nation feel little respite from unrelenting temperatures. Northern India has endured a scorching summer — with one part of the capital of Delhi recording the country’s highest-ever temperature 49.9 degrees Celsius (121.8 degrees Fahrenheit) earlier this month. But the stifling heat persists even after the blazing sun has set. The city is cooling down by only 8.5 degrees Celsius at night compared to a 12.2 degrees cooling down in urban outskirt areas, a report published by the Centre for Science and Environment (CSE) last month tracking urban heat stress in Delhi has found. The warmer nights deprive people of rest and recovery from long hours of exposure to oppressive heat, particularly for people without access to air conditioning.

Exposure to heat waves during pregnancy may be associated with adverse outcomes such as preterm birth, according to a 2019 study. Older adults may have higher heart rates and more physiological stress when sleeping in warmer temperatures. A 2008 Australian study even found deaths due to mental and behavioral disorders rose during heat waves, especially for older adults. Increasing nighttime heat is even more common in cities like Delhi because of the urban heat island effect, in which metro areas are significantly hotter than their surroundings. Areas with a lot of asphalt and dense concrete buildings absorb more of the sun’s heat than areas with ample parks, rivers and tree-lined streets. The hot days and nights are testing the limits of the country’s electricity grid and water supply, and the strain on resources is already making people sick. “We’ve been living in this neighborhood for 40 years, but we have never seen a summer like this,” said 60-year-old Kalyani Saha, a resident of the Lajpat Nagar neighborhood of the capital city. “There hasn’t been power for the last two hours, in the middle of the day that’s unbearable,” Saha told CNN, saying that power cuts also render their air-conditioning system useless. “We get water only once a day, and it’s scalding hot, unless you fill up a bucket and let it cool off all day before using it, you can’t bathe in this water,” she said. Saha also said her grandson has been ill for a week. “They’re small, they can’t cope with this, this is not a human level of heat,” she said. At least 40,000 cases of heat stroke have been reported in India since March, an official in the Ministry of Health told CNN Thursday, and at least 110 people have died across the country due to suspected heat stroke as well. Dr Ajay Chauhan, in charge of the first of its kind heat-stroke unit at Delhi’s Ram Manohar Lohiya (RML) hospital says hotter nights mean increased stress on the bodies. “When a person has a heat stroke, things progress very quickly, so without early intervention the fatality rate of heat strokes is very high,” Chauhan said. Chauhan said people who work outdoors all day need time to cool down and recover but he concedes “that’s not been possible.” At least 11 people have died as a result of heat strokes at his hospital since May 29 and on Thursday alone over 20 new patients were admitted to the hospital for various heat-related illnesses. Over the past five decades, India has experienced more than 700 heat wave events claiming more than 17,000 lives, according to a 2021 study of extreme weather in the Weather and Climate Extremes journal. Delhi recorded the highest numbers of homeless deaths in the last five years during the 9-day stretch. Between June 11 and 19, Delhi saw 192 heatwave-related deaths among its homeless population, a record high compared with the same period in the last five years, according to a report from the NGO Centre for Health Development India. “Almost everyone living on the streets reported experiencing sleeplessness,” the report said, adding that they suffered from several heat-related ailments. Sarita Kumari has been sleeping on the streets of Delhi with her three children, and told CNN her three-year-old son has been running a high fever all week. “We do have a house but there’s a lot of us and when the power goes it gets suffocating,” Kumari said. — CNN

Explainer: रात में बढ़ रही जानलेवा गर्मी, जानिए क्या है इसकी वजह

दिल्ली समेत पूरे देश में जानलेवा गर्मी का कहर जारी है। दिल्ली के कुछ हिस्सों में तापमान 47 डिग्री तक छू चुका है। रात में भी गर्मी का तापमान रिकॉर्ड तोड़ रहा है। मौसम विभाग भी लू या यू कहें कि हीट वेव को लेकर कभी रेड तो कभी ऑरेंज अलर्ट जारी कर रहा है। 19 जून को दैनिक जागरण की वेबसाइट पर छपी खबर में लिखा है कि दिल्ली में 18 जून की रात को तापमान ने नया रिकॉर्ड बनाया। न्यूनतम तापमान 35.2 डिग्री रहा, जो सामान्य से आठ डिग्री अधिक है। इससे पहले 3 जून 2010 को न्यूनतम तापमान 34.7 डिग्री पहुंचा था। vishvasnews कम हो रहा दिन और रात के तापमान का अंतर सेंटर फॉर साइंस एंड एन्वायरन्मेंट (सीएसई) ने बेंगलुरु , चेन्नई, दिल्ली, हैदराबाद, कोलकाता और मुंबई में गर्मी के दौरान एक अध्ययन किया था। 24 मई 2024 को वेबसाइट पर दी गई जानकारी के अनुसार, मार्च-अप्रैल 2024 में दिल्ली का औसत तापमान 2014-2023 के औसत तापमान के मुकाबले 3 डिग्री कम रहा, लेकिन अधिक आर्द्रता हीट स्ट्रेस को बदतर बना रही है। दिन और रात के तापमान में अंतर 9 फीसदी कम हुआ है। रात में शहर का तापमान केवल 8.5 डिग्री, जबकि आसपास का तापमान 12.2 डिग्री कम हुआ है। इससे पता चलता है कि शहरी क्षेत्र आसपास के इलाके के मुकाबले 3.8 डिग्री कम ठंडा हो रहा है। यह अर्बन हीट आइलैंड का असर है। यहां 2003 में निर्माण क्षेत्र 31.4 फीसदी था, जो 2022 में बढ़कर 38.2 फीसदी हो गया। हालांकि, ग्रीन कवर क्षेत्र 2003 के 32.6 फीसदी से बढ़कर 2022 में 44.4 फीसदी हो गया, लेकिन इसके बढ़ने का असर दिन के तापमान पर तो दिखा, लेकिन रात के पारे पर इसका कोई असर नहीं पड़ा। इस अध्ययन से पता चलता है कि अर्बन हीट आइलैंड का असर दिल्ली के तापमान पर भी दिख रहा है। vishvasnews 27 अक्टूबर 2023 को सीएसई की वेबसाइट पर छपी एक रिपोर्ट के अनुसार, इंटरनेशनल पैनल ऑफ क्लाइमेंट चेंज ने चेताया है कि अर्बन हीट आइलैंड के असर से वातावरण में गर्मी दो डिग्री तक बढ़ सकती है। रिपोर्ट में यह भी बताया गया है कि रात में बढ़ रहा तामपान दोपहर के अधिकतम तापमान जितना ही खतरनाक होता है। रात भर तापमान अधिक रहने से शरीर पर इसका घातक असर पड़ता है। इससे लोगों को दिन की गर्मी से उबरने का बहुत कम मौका मिलता है। चीन, दक्षिण कोरिया, जापान, जर्मनी और अमेरिका के वैज्ञानिकों द्वारा लैंसेट प्लैनेटरी हेल्थ में प्रकाशित 2022 के एक अध्ययन में कहा गया है कि अत्यधिक गर्म रातों से मृत्यु का खतरा लगभग छह गुना बढ़ जाएगा। vishvasnews नासा की वेबसाइट पर 12 मई 2022 को एक रिपोर्ट छपी है। इसमें 5 मई 2022 की रात को नासा के इकोस्ट्रेस द्वारा ली गई दिल्ली के सतह की तस्वीर के आधार पर कहा गया है कि दिल्ली के अर्बन ‘हीट आइलैंड्स ‘ और छोटे गांवों का तापमान 102 डिग्री फॉरेनहाइट (39 डिग्री सेल्सियस) रहा, जबकि आसपास के क्षेत्र 40 डिग्री फॉरेनहाइट ठंडे थे। शहरों के अपने आसपास के क्षेत्रों से ज्यादा गर्म होने की वजह मानवीय गतिविधियां और इमारतों के निर्माण में इस्तेमाल होने वाली सामग्री है। vishvasnews क्या होता है अर्बन हीट आइलैंड नेशनल जियोग्राफिक की वेबसाइट के अनुसार, अर्बन हीट आइलैंड (यूएचआई) वह क्षेत्र होता है, जो अपने आसपास के ग्रामीण इलाकों के मुकाबले गर्म होता है। इसके पीछे काफी कारण होते हैं। जब घर, दुकानें और व्यावसायिक इमारतें काफी नजदीक बनती हैं तो यह हीट आइलैंड का कारण बनती हैं। भवन निर्माण में इस्तेमाल होने वाली सामग्री भी हीट को रोकने या उसे इंसुलेट करने में काफी कारगर होती है। इस इंसुलेशन की वजह से आसपास की इमारतें गर्म होती हैं। वाहनों से निकलने वाली गर्मी भी इसकी वजह बनती है।
