Don't Step Out: Oncologist Says Smoking Becomes More Dangerous During A Heatwave

Smoking

Indian summers are not just uncomfortable; they are becoming increasingly dangerous. With temperatures frequently crossing 45–48°C, <span>heatwaves</span> are putting excess <span>stress</span> on the human body, which hitherto had not experienced this level of heat strain. Now, add <span>smoking</span> to this already hostile environment and, like adding fuel to a fire, two harmful components combine to multiply the damage. Dr Shubham Garg, Director of Surgical Oncology, Dharamshila Narayana Superspeciality Hospital, Delhi, spoke about the risks of stepping out to grab a smoke during extreme heatwaves. 

Smoking during heatwaves doesn’t just worsen existing risks; it accelerates <span>dehydration</span>, strains the heart, damages the lungs, and pushes the body closer to heat exhaustion or heatstroke. Here’s why lighting up in extreme heat is far more dangerous than most people realise.

<h2>Heatwaves Already Stress the Body—Smoking Adds Fuel to the Fire</h2>

When temperatures soar, your body works overtime to cool itself. A host of processes happen to aid in this—your blood vessels dilate, there could be an increase in heart rate, and sweating intensifies in order to regulate body temperature. When you smoke, it interferes with these very natural defense mechanisms of your body.

Nicotine results in vasoconstriction—narrowing of blood vessels—which makes it very difficult for the body to release heat trapped inside. The carbon monoxide from cigarettes reduces oxygen delivery to tissues. The result? Less oxygen reaches your organs, which are, in fact, working harder in the extreme heat. This is a perilous combination that can affect the body in many ways.

<h2>Dehydration Happens Faster Than You Think</h2>

A <span>heatwave</span> leads to sweating and, consequently, loss of fluids and electrolytes. And when you go for smoking a cigarette, it leads to fluid loss and delayed hydration. Nicotine acts as a mild diuretic, which contributes to increased fluid loss. Smoking also suppresses thirst signals, thus delaying hydration.

Collectively these factors raise the risk of severe dehydration, which can trigger dizziness, muscle cramps, low blood pressure, and confusion—all of which are early signs of heat exhaustion. Many smokers ignore these signs or dismiss them altogether.

Cardiovascular strain can happen independently through either smoking or heat. That in itself is a threat one should keep an eye out for. However, when combined, they pose a compelling risk of:

<ol><li>Sudden spikes or drops in blood pressure</li><li>Irregular heart rhythms</li><li>Heat-induced cardiac events</li></ol>

During extremely hot weather conditions, especially during a heatwave, the heart has to exert more effort to maintain circulation and cooling in the body. Smoking elevates heart rate and blood pressure further while also thickening the blood and increasing the risk of heart attacks and strokes, especially in people with pre-existing diabetes, hypertension, or heart disease.

<h2>Lungs Struggle More in Hot, Polluted Air</h2>

Hot weather is bad for air pollution levels too, as it traps smoke, dust, and harmful gases close to the ground. When one smokes in these conditions, it severely compromises lung function:

<ol><li>Airways become inflamed and constricted</li><li>Oxygen exchange efficiency drops</li><li>Symptoms like breathlessness, coughing, and chest tightness worsen</li></ol>

For people with asthma, COPD, or other respiratory conditions, smoking during a heatwave is likely to trigger severe flare-ups and emergency hospital visits.

<h2>Heat + Smoking Accelerates Ageing and Skin Damage</h2>

Extreme heat is damaging not just for the heart but for the skin as well. The skin becomes dehydrated, and collagen breaks down. Smoking compounds this damage by reducing blood flow and oxygen supply to the skin.

<ol><li>Faster wrinkles and sagging skin</li><li>Increased pigmentation and dullness</li><li>Delayed healing of rashes, infections, and sun damage</li></ol>

In short, smoking during summer doesn’t just harm internal organs; it visibly accelerates the ageing process.

<h2>Higher Risk of Heat Exhaustion and Heatstroke</h2>

Smoking reduces the body’s ability to regulate temperature effectively. This makes smokers more vulnerable to heat exhaustion (fatigue, nausea, headache, dizziness) and heatstroke (confusion, collapse, organ failure).

Heatstroke is a medical emergency and can be fatal if not treated promptly. Smokers often misread early warning signs as ‘normal summer weakness,' thus delaying care.

Many smokers try to “reduce” smoking during summer. While any reduction helps, heatwaves are one of the worst times to smoke at all. Even a few cigarettes can significantly increase physiological stress when temperatures are extreme.

Smoking during heatwaves is not just bad—it’s dangerously synergistic. If there ever is a time to quit, or at least pause, this should be it. Because in peak summer, smoking doesn’t just harm you slowly. It fast-tracks damage, turning heat into a silent but serious health threat. In extreme heat, choosing not to smoke isn’t just a lifestyle choice—it’s a life-saving one.
