The brain is a complex part of our bodies, and we don’t actually know all of the ways in which nicotine withdrawal causes sleep disturbances. What we can tell you is that it affects everyone differently – the greater your addiction to nicotine, the worse the sleep disturbance you may experience. You might also find that your symptoms change during the course of your withdrawal.

Some of the more common symptoms include:

  • the quality of your sleep just isn’t as good
  • you wake up briefly lots of times during the night
  • you are awake for long times throughout the night
  • you are tired during the day.


If you’ve kicked a smoking habit – or are even just considering it – good for you! Smoking increases the risk of heart attack, stroke and cancer – and it’s the single largest cause of preventable death in the United States. In fact, not smoking is among the best things you can do for your health. But quitting may cause some short-term woes.


No Smoke, No Sleep?

People who are still smoking often experience disrupted sleep. But studies suggest solid shuteye is even harder to come by in the early days and weeks after quitting. About half of former smokers have trouble sleeping while they’re trying to quit. And the resulting sleep deficit can make it difficult to stay away from cigarettes.

“Nicotine has a stimulating effect, but it also has an overall mood-modulating effect,” says Amanda Holm, M.P.H., tobacco treatment manager at Henry Ford Health System. “If you’re bored, sleepy or tired, nicotine will act as a stimulant to help you feel more alert and awake. But, if you’re feeling anxious, it will smooth out your anxieties. If smoking helps keep you on an even keel throughout the day, that can become a problem after you quit.”


The Effect of Nicotine on Your ZZZ’s

Here’s how nicotine affects your sleep – both while you’re still smoking and in the weeks after you quit.

While you’re smoking: Nicotine disrupts sleep – and smoking can also raise the risk of developing sleep conditions, such as sleep apnea. But since nicotine is a stimulant, smoking can mask your exhaustion. After all, if you’re feeling sleepy, a hit of nicotine can wake you up and make you feel alert the next day.

When you’re quitting: The first few days without cigarettes will likely come with some unpleasant side effects. There are nerve endings and receptors all over the body that respond and react to nicotine. People may experience everything from constipation and diarrhea to headaches and anxiety. As your body acclimates to functioning without nicotine and other dangerous chemicals, you may experience cravings, irritability and yes, sleepless nights.

“When people quit, they’re dealing with the withdrawal symptoms at night, too, which can keep them awake,” Holm says. “Plus, some of the medications prescribed to aid with smoking cessation can give people vivid dreams.”


Tips to Get Better Sleep

Establishing good sleep habits is important whether you’re a smoker, former smoker or have never puffed a cigarette. Here are five suggestions:

Cut down on the caffeine. It seems obvious, we drink caffeine to wake us up. So when you are trying to sleep, it is the last thing you need. But what you probably didn’t know is that when you quit smoking, your body absorbs almost twice as much caffeine as before, making it even more important that you reduce your caffeine intake. Try swapping out coffee and tea with herbal teas when you first quit.

Timetable it in. Try and keep a consistent sleep schedule: go to bed at the same time, and get up at the same time every day, even on weekends. Make sure you set a bed time that lets you get at least 7 hours of sleep. Don’t succumb to the need for a nap – you might think that any sleep is good, but if you sleep during the day, you may pay for it when you try and sleep that night.

Listen to your body. Don’t go to bed unless you are tired, and if you don’t fall asleep after 20 minutes, get up. There is nothing worse than lying in bed waiting for sleep to come.

Start a relaxing bedtime routine. Turn off your phone, the computer, and even the TV. Have some quiet time for yourself to put you in the mood to sleep. Try a relaxing bath, or read a book. Have a warm cup of milk, or a herbal tea. Listen to some calming music.4,5

Watch what you eat. Try not to eat a big meal before you head to bed. If you are hungry, make sure you stick to light healthy snacks to tide you over to breakfast. Try and avoid drinking alcohol in the evenings too.


“Your withdrawal symptoms – and even sleep disturbances – will resolve over time,” Holm says. Symptoms usually begin within hours of quitting, peak within the first few days and subside within a few weeks.

In the meantime, identify feel-good ways to reward yourself for remaining smoke-free. Buy a pair of movie tickets, treat yourself to a nice meal or spring for a massage. And, if you’re having difficulty sleeping during the quitting process, talk to your doctor.

“Some tobacco cessation aids can contribute to insomnia,” says Holm. Your healthcare provider or tobacco treatment coach may suggest ways to encourage more shuteye, such as taking your doses earlier in the day or removing a nicotine patch overnight.
