Karachi’s thermometers hit 44°C this May — and the worst of summer 2026 is still ahead. While everyone feels the discomfort of extreme heat, for people with heart disease, asthma, COPD, or diabetes, Pakistan’s record heatwave is not just an inconvenience. It is a medical emergency waiting to happen. Understanding the heatwave health risks Pakistan’s most vulnerable patients face — and what to do about them — could save your life or the life of someone you love.
How Extreme Heat Attacks Your Heart
When temperatures soar past 40°C, your heart has to work significantly harder. Blood vessels dilate in an attempt to push heat to the skin surface. The heart pumps faster to keep up. For a healthy person, this is manageable. For someone with an existing heart condition, this extra strain can trigger chest pain, arrhythmia, or even a heart attack.
Research published in medical literature confirms that heart failure is an independent risk factor for heatstroke-related death. Patients with cardiovascular disease face dramatically elevated risk during sustained heatwaves — precisely the kind Pakistan is currently experiencing, with Climate Change Ministry projections indicating 5–7 heatwave days per month this season, up from 3–4 historically.
And yet, for many cardiac patients, the heat creates a painful catch-22: they need monitoring, but the thought of travelling to a clinic in 44°C heat — with power outages, traffic, and physical exertion — poses its own serious risks.
Heatwave Health Risks Pakistan Lung Patients Cannot Ignore
Extreme heat does not just stress the cardiovascular system. The lungs suffer too. Here is why:
- Hot, dry air irritates airways — triggering asthma attacks and bronchospasm even in patients who are otherwise stable
- Heat accelerates ozone formation — worsening air quality and making COPD and respiratory conditions harder to manage
- Dehydration thickens mucus — making breathing more laboured and increasing infection risk
- Reduced indoor air circulation — due to load-shedding, increases exposure to indoor allergens and pollutants
Karachi’s combination of intense heat and low humidity — dropping to just 8% on several May 2026 days — creates a particularly harsh respiratory environment. For children with asthma, seniors with COPD, or anyone with post-COVID lingering lung sensitivity, this season demands active monitoring.
Who Is at Highest Risk This Summer
Pakistan’s health authorities and climate researchers have identified the most vulnerable groups:
- People with diagnosed heart disease, arrhythmia, or hypertension
- Asthma and COPD patients
- Diabetics — heat impairs blood sugar regulation and accelerates dehydration
- Seniors over 60, whose bodies are less efficient at cooling
- Children under 5, particularly those with respiratory conditions
- Outdoor workers and anyone without reliable air conditioning
Waiting until symptoms become severe before seeking medical advice is a strategy that has cost lives in past Karachi heatwaves. The 2015 heatwave claimed over 1,200 lives — many of those deaths involved pre-existing cardiac and respiratory conditions that went unmonitored during the critical early warning period.
Remote Clinical Examination: Monitor Your Health Without the Heatwave Risk
This is where CARELINE’s approach makes a critical difference — and why it matters more in summer than at any other time of year.
A standard video call cannot tell your doctor whether your heart sounds have changed, whether your lung fields show new wheeze or crackle, or whether your oxygen saturation is dropping silently. But CARELINE’s remote examinations using Finland’s eEVA™ device deliver all of this — without you stepping out into the extreme heat.
The eEVA™ device, used by a trained CARELINE health facilitator at your nearest partner pharmacy, gives your doctor:
- Live heart and lung auscultation — the same clinical data as a face-to-face examination
- Real-time oxygen saturation, pulse, and blood pressure readings
- Body temperature and vital sign assessment
- A full specialist consultation across cardiology, pulmonology, ENT, and general medicine
For cardiac and respiratory patients, accessing this level of clinical assessment from a nearby pharmacy — rather than travelling across the city in extreme heat — is not just convenient. It is the medically safer option. You eliminate the very physical exertion and heat exposure that could trigger the cardiac or respiratory event you are trying to prevent.
What You Should Do Right Now
If you or someone in your family has heart disease, a lung condition, diabetes, or another chronic illness:
- Do not skip monitoring — this is precisely when it matters most
- Watch for warning signs: unusual fatigue, shortness of breath, chest tightness, dizziness, or reduced urine output
- Limit outdoor exposure between 11am–5pm and stay well hydrated
- Book a CARELINE remote clinical examination — get your heart and lungs properly checked, without the heatwave risk
Pakistan’s 2026 heatwave is not going away quickly. But with the right clinical monitoring in place, a dangerous summer does not have to become a medical crisis.

Frequently Asked Questions
What is CARELINE telehealth?
CARELINE is Pakistan’s first DRAP-licensed telehealth provider that uses the eEVA™ device — developed by Finland’s 73Health — to deliver real remote clinical examinations. Unlike video-call-only services, eEVA enables digital stethoscopy, lung sounds, ENT examination, and dermatological assessment, all without visiting a hospital.
How does the eEVA™ device work?
The eEVA™ (electronic EVAluation) device is placed on the patient at a CARELINE-enabled pharmacy, workplace, or home visit. It connects to a specialist doctor via live video who performs a full clinical examination in real time — listening to your heart and lungs, examining your ears, throat, and skin — exactly as they would in a clinic.
