Degree programme: stopping heat deaths

Global Heat Waves and Climate Adaptation

• Record temperatures have triggered heat waves across four continents, causing fatalities and infrastructure stress.
• In Saudi Arabia, temperatures exceeding 50°C (122°F) contributed to the deaths of over 1,300 Hajj pilgrims, many of whom were unregistered and lacked access to air-conditioned shelters.
• Extreme heat events are now considered immediate realities rather than future risks due to current warming levels, necessitating urgent adaptation plans beyond general climate mitigation.
• Vulnerability to heat is heavily correlated with inequality, with indoor temperatures in Mumbai slums averaging six degrees higher than nearby suburbs.
• During a 2023 Arizona heatwave, 45% of deaths occurred among the homeless population.
• In the US, neighborhoods in New York and London with higher poverty rates and non-white demographics experience significantly higher indoor temperatures than wealthier areas like Central Park.
• Occupational heat exposure disproportionately affects blue-collar workers in agriculture, warehouses, and factories, often due to poor ventilation and lack of protections.
• The Biden administration is attempting to mandate federal heat protections for workers (shade, water, rest breaks), facing significant industry pushback regarding costs.
• A 2023 Lancet analysis estimated that access to air conditioning prevented approximately 190,000 heat-related deaths globally among people over 65 in a single year.
• France implemented a comprehensive heat action plan following the 2003 heatwave that killed tens of thousands; subsequent waves in 2019 resulted in 90% fewer casualties despite similar or higher temperatures.
• Policy recommendations include reflective building coatings (e.g., white roofs), flexible work hours, and the establishment of public cooling centers in schools and community hubs.

Shift in International Student Demographics

• Chinese students, historically the largest international cohort, are declining in number, while Indian students are becoming the primary engine of growth in global higher education.
• In the first 10 months of 2023, 750,000 Indians studied abroad, a 30% increase compared to 2019.
• Since 2022, the US and UK have issued more student visas to Indian citizens than to Chinese ones, a reversal not seen in 15 years.
• India's surge in outbound students is driven by a massive, rapidly aging population (1 million 18-year-olds monthly), rising GDP per capita (5x growth in 20 years), and a domestic university system where top institutions are harder to enter than Ivy League schools.
• Indian students increasingly rely on fintech loans to finance their studies, whereas Chinese students historically utilized family savings.
• Indian students often attend less prestigious, more affordable institutions and pursue shorter courses; in the UK, typical Indian tuition fees are half those of Chinese students.
• Unlike Chinese students who historically returned home post-study, Indian students increasingly seek to remain abroad via post-study work visas to repay loans and build careers.
• International students provide outsized financial support, with foreigners comprising 25% of UK students but generating over 40% of tuition fee revenue.
• In the US, 25% of billion-dollar startups are founded by immigrants who arrived as international students.
• A shift in student demographics from China to India is aggravating immigration debates, with authorities increasingly scrutinizing Indian visa applications and fearing the "brain drain" from India, despite India viewing returned students as "flag bearers" bringing valuable skills.
• Western universities face a risk of revenue shortfalls if they raise immigration barriers, as their growth models have become reliant on foreign student fees.

The Rise of "Full-Body" Deodorant

• Americans spent $6.6 billion on deodorant last year, averaging $20 per capita, nearly double the spending per person in France.
• The market is shifting from underarm-only products to "full-body" deodorants targeting areas such as feet, knee crevices, underboobs, and genitals.
• The trend was pioneered by the company Lume (founded in 2017 by a gynecologist), which markets products for "all folds of skin."
• Marketing for these products often employs irreverent tones and induces anxiety about body odor, claiming it undermines self-worth and confidence.
• Unlike antiperspirants, these products do not block sweat glands, allowing natural cooling to continue while masking odor.
• Medical professionals, including gynecologist Jennifer Lincoln, warn against using fragranced deodorants in sensitive areas due to risks of irritation and infection.
• Critics argue that the marketing narrative normalizes harmful gender expectations regarding female body odor rather than genuinely empowering women.
