That smoking is injurious to health is a known fact. But what if there’s a particular time of day when the risk multiplies manifold?
According to Dr Vikas Mittal, Pulmonologist and Director at Wellness Home Clinic and Sleep Centre, Paschim Vihar, the cigarette you light up right after waking could be the most dangerous one of your day. Even if you smoke significantly fewer times than a chain smoker, the timing of that first puff may be putting your lungs and heart at significantly greater risk.
Your body wakes up in a reset mode, says Dr Mittal, adding that the “lungs are more sensitive, hormone levels are elevated, and your systems are vulnerable in the morning. That’s what makes early-morning smoking a high-risk behaviour, even if someone smokes only a little.”
Why mornings are riskier than you think
While you are asleep, the lungs get a temporary break from toxins and begin to recover, just like any other organ. When you smoke right after waking, this fragile repair process is interrupted. “The chemicals hit sensitive and relatively ‘fresh’ airways, causing greater irritation and absorption of toxins,” the expert adds.
Additionally, those who reach for a cigarette within 30 minutes of waking also tend to inhale more deeply, worsening the risks. “The closer a cigarette is to waking up, the higher the nicotine and toxin absorption,” he says. “This increases carcinogen exposure and accelerates damage to blood vessels, raising cardiovascular risks. Smoking within 30 minutes of waking is also considered one of the strongest predictors of developing lung cancer. This simple habit signals higher dependence on nicotine and higher toxin absorption, which drastically raises long-term health risks compared to smokers who wait longer.”
What your lungs go through in those first few minutes
After the sleep sort of resets the lungs, they become more vulnerable to everything. Dr Mittal explains that after a night of rest, the airways are less coated with the mucus and protective secretions that typically shield them from damage.

“This means the toxins from cigarette smoke directly irritate the lining of the lungs,” he says. “The tar and chemicals cling more easily to airway walls, leading to inflammation and damage.”
Worse still, the nicotine and toxins enter the bloodstream within 10-20 seconds of inhalation. “This creates an immediate spike in heart rate, blood pressure, and stress hormones,” he explains. “For the rest of the day, the body remains in a state of imbalance, with blood vessels constricted and oxygen delivery reduced.”
It also sets the tone for the rest of the day’s addiction pattern. “Morning smoking primes the brain for stronger nicotine cravings, making quitting harder,” Dr. Mittal adds.

That dizzy rush? It’s not a good sign

Many smokers report that the first cigarette of the day hits the hardest and helps them kick start the day with a jolt. That sensation, however, is actually a red flag, not a benefit. “After a night’s break, nicotine levels in the blood are at their lowest,” Dr. Mittal explains. “The first cigarette quickly restores and overshoots these levels, giving a rush of stimulation to the brain.”
The sudden jolts, light-headedness, and euphoric feelings also stem from the nervous system being overstimulated due to oxygen deprivation. “The dizziness is actually a sign of oxygen deprivation and nicotine’s effect on the nervous system — not something positive.”
A stress cocktail your body doesn’t need
When we wake up in the morning, the levels of cortisol and adrenaline are higher. They help a person become more alert and focused. But these hormones can also heighten stress responses, especially when nicotine is added to the mix. “It causes increased heart rate, blood pressure, and stress on the cardiovascular system. So while people are reaching out for the morning puff to relax, it could ironically intensify it. Over time, this exaggerated hormonal response can lead to hypertension, anxiety, heart attacks, and strokes,” he says.
Can delaying that first cigarette actually help?

Yes. If someone is unable to quit smoking altogether, even pushing the first cigarette later in the day helps. “It reduces nicotine dependence, lowers overall toxin exposure, and gives the lungs more time to recover from the night’s rest,” says Dr. Mittal. “While quitting completely is the best option, even this small change can improve long-term health outcomes.”
