Cold wave triggers spike in cardiac arrests

Cold wave triggers spike in cardiac arrests

Mumbai : As winter temperatures go for a spin across the country, hospitals are witnessing a significant surge of around 25-30 pc in cardiac emergencies, a top cardiologist said.   According to Interventional Cardiologist Dr. Hemant Khemani of Apex Group of Hospitals, cold air directly affects how the heart functions.   “Low temperatures make blood vessels tighten. When the arteries narrow, blood pressure shoots up and the heart has to work harder to push the blood through the stiffened vessels,” said Dr. Khemani.   Elaborating on the direct effects of cold air on heart functioning, he said that low temperatures make blood vessels tighten, when arteries narrow, blood pressure shoots up and the heart must work harder to push blood through stiffened vessels.   Winter also thickens the blood, increasing the likelihood of clot formation and these combined effects create a dangerous ‘demand-supply mismatch’ for oxygen, especially in people with existing heart conditions.   This trend has caused concern among cardiologists as it adds to India’s already heavy cardiovascular diseases burden – with nearly one in four deaths linked to heart and blood vessel problems.   Dr. Khemani said that sudden temperature transitions - from warm rooms to chilly outdoors - can put additional strain on the heart and risks. “This abrupt shift loads the cardiovascular system quickly, raising the risk of a sudden (cardiac) event among vulnerable individuals.”   Lifestyle Patterns Added to these are the changes in lifestyle patterns during winter month that further amplify the danger. Most people reduce physical activities, eat richer foods, and often gain weight all of which combine to raise cholesterol levels, disrupt blood-sugar balance and push up blood pressure.   Complicating matters for the heart are the social gatherings during the cold season that tends to bring higher intake of smoking and alcohol, said Dr. Khemani.   Recommending basic preventive measures, Dr. Khemani said the chest, neck and hands must be kept warm to prevent heat loss, maintain a steady body temperature and reduce the chances of sudden blood pressure spikes, a low-salt diet, home-cooked meals, shot indoor walks post-eating, adequate hydration and at least seven hours of sleep.   He warns against ignoring warning signals such as chest discomfort, breathlessness, unexplained fatigue, or sudden sweating, pointing out that “early medical care can significantly limit heart damage and improve survival.”   The rise in winter heart risks is not unique to India and even global health agencies like World Health Federation and World Health Organisation report similar patterns.   The WHF estimates that more than 20 million people die of heart-related causes each year - equal to one life lost every 1.5 seconds, and the WHO has listed heart disease as the world’s leading cause of death for five consecutive years.   Seniors affected more by winter chills  Cold weather can hit the heart at any age, but the risk is noticeably higher for men aged above  45 and in women after 55, with the highest danger curve in people over 60, and elders with co-morbidities and history of heart diseases.   “People with existing cardiac problems face greater trouble in winter as the heart has to work harder. Even those without known heart disease can sometimes experience winter heart attacks, as chilly conditions may expose hidden blockages or trigger problems due to sudden exertion, heavy meals, smoking or dehydration,” Dr. Khemani told  ‘ The Perfect Voice’ .   However, contrary to perceptions, cold-weather heart issues have no connection to the COVID-19 vaccine, nor is there any scientific evidence linking the two, he assured.

Uniform Before Faith

The Supreme Court’s ruling on an officer’s dismissal affirms a hard truth about military service in a plural republic.

The recent dismissal of Lieutenant Samuel Kamalesan from the Indian Army has become a minor culture war in uniform. The case has been framed by its critics as a test of India’s secular soul, and by its defenders as a necessary assertion of military discipline. The question at the heart of this affair is how far can personal conscience travel inside an institution built on command, cohesion and unquestioning obedience?


Lt Kamalesan, a Protestant Christian, was dismissed after refusing to participate in his regiment’s mandatory religious observances popularly known as mandir parades, despite repeated counselling by his commanding officer and even by a pastor. He objected on grounds of conscience, declining to enter the unit’s temple or gurdwara during prescribed parades. The Supreme Court last month upheld his dismissal, endorsing the Army’s view that his refusal constituted “the grossest kind of indiscipline” and rendered him unfit for leadership.


The bench, led by the Chief Justice, ruled that where personal religious freedom collides with the imperatives of discipline and cohesion in the armed forces, the latter must prevail. The backlash was swift and predictable. Civil liberties groups and sections of minority advocacy networks accused the court of subordinating religious freedom to military conformity, of setting a harsh precedent for conscience-based dissent and of sending an unflattering signal about India’s commitment to secularism. Some argued that the punishment, which is dismissal without pension, was disproportionate to the offence, especially given the lieutenant’s otherwise unblemished service record. Others warned that the ruling would deepen anxieties among Christian communities already facing legal and social pressures.


But to see this case purely through the lens of religious identity is to misunderstand both the nature of military institutions and the Constitution that governs them.


Larger Purpose

India’s armed forces are not secular in the abstract, civilian sense. They are instead resolutely religion-neutral in purpose, but deeply ceremonial in form. Regimental traditions, many dating back to colonial times, blend faith, folklore and martial ritual in ways that often confound civilian categories. A mandir parade is less about theology than about collective rhythm: the same event may involve a havan in one unit, a path in another, or namaz before a major operation. These observances are not private acts of worship but public expressions of unit identity which are meant to steel morale, cultivate shared resolve and remind soldiers – who live with death as a routine occupational risk - that they are part of something larger than themselves.


Such practices are ubiquitous, institutionalised and well known. It strains credulity to suggest that an officer could pass through the arduous selection boards, months of military training and regimental induction without understanding this basic feature of Army life. Military service is not bonded labour. It is a voluntary submission to a strict code in which the space for individual exception is tightly constrained. To sign up is, in effect, to agree that the uniform will sometimes eclipse the self.


That is precisely what the Supreme Court affirmed. Its ruling was not a commentary on Christianity, Hinduism or any other faith, but on the hierarchy of obligations within the military. An officer leads by example, the court observed; selective participation in regimental life erodes authority in the eyes of subordinates. To permit individual opt-outs in matters that bind the unit together tantamounts to institutional corrosion.


Constitutional Exception

The constitutional architecture supports this view. Article 25 guarantees freedom of conscience and the right freely to profess, practise and propagate religion. But Article 33 explicitly empowers Parliament to modify these rights for members of the armed forces to ensure discipline and the proper discharge of duties. This is a recognition that the military is a constitutional exception.


Critics who portray the verdict as an assault on minority rights overlook a symmetrical truth: had a Hindu or Muslim officer refused to attend a church service forming part of a regimental observance, the outcome would almost certainly have been the same. What matters is not which faith is invoked, but whether the chain of command is obeyed.


The deeper danger lies not in the court’s ruling, but in the politicisation of the case that has followed. By casting a question of discipline as a drama of ‘religious persecution,’ the activists are importing the vocabulary of identity conflict into one of the few institutions that still operates on non-partisan and non-sectarian lines. The Indian Army’s legitimacy rests not on ideological consensus but on professional trust: Hindu, Muslim, Christian, Sikh and atheist fight and die under the same flag, subject to the same drill, the same risks and the same orders. To fracture that compact by sowing suspicion about institutional bias is to play with national security as a rhetorical prop.


The critics’ most emotive claim that the judgment hollows out Indian secularism rests on a fragile foundation. Indian secularism has never meant the strict exclusion of religion from public institutions; it has meant equal recognition and principled distance. The Army’s multi-faith ethos, in which different units observe different religious traditions without elevating one as the state faith, arguably embodies this model more faithfully than many civilian spaces do today.


India’s critics would do well to remember that the uniform is designed to erase, not amplify, the distinctions that animate civilian politics. Its promise is not of personal affirmation, but of collective purpose. The Supreme Court’s ruling, stripped of its ideological adornments, is a blunt reaffirmation of that principle.
