Why Cigarettes Make You Feel Tired

Cigarettes are one of the main causes of preventable deaths world over. Use of tobacco in the form of cigarettes has many adverse health effects. Though cigarettes make you feel relaxed for a short period, they are doing more harm to your body in the long run. After using cigarettes for a long period of time the smoker will feel that they are more tired and by that time most the damages might have occurred in the body.

Reduces the Efficiency of Lungs

One of the main reasons for the smokers to feel tired is that their body may not be receiving enough oxygen due to the damages caused by the cigarette smoke. Cigarette smoke contains various toxins, including tar which affect the cleaning process of the lungs by sticking to the lungs. This will reduce the oxygen absorbing capacity of the lungs. When the body organs like heart and brain do not get enough oxygen we feel tired. The blocked airways in the lungs cause continuous cough as the lungs fail to eliminate the dirt containing mucous from the lungs.

Causes Pulmonary Diseases

Smoking causes damage to the lungs due to exposure to carbon monoxide and cyanide in the cigarette smoke. The alveoli of the lungs lose the elasticity and this will lead to chronic obstructive pulmonary disease or COPD. This disease cause shortness of breath, bronchitis, wheezing, etc. all these health problems can lead to tiredness.

Affects the Cardiovascular System

The smoke from tobacco has several immediate effects on the working of the heart and blood vessels.

  • When you start smoking, the heart rate increases by 30% within the first 10 minutes, this will put a strain on your heart muscles as they have to beat faster to maintain the blood supply to the organs.
  • The oxygen carrying ability of the blood decreases due to the carbon monoxide absorbed into the blood while smoking.
  • The organs will not receive the required oxygen and makes you feel tired.
  • The toxic ingredients in tobacco smoke can cause narrowing of blood vessels which may lead to increased blood pressure and stroke.


Increases Chances of Infections

lung efficiencyA smoker is more susceptible to infectious diseases. They are more prone to infections like influenza, mucosal lesions and lung infections. Nicotine in smoke causes structural damages to the tissues and affects the immune response of the body. The smokers are also more susceptible to HIV infection. Chronic bronchitis and emphysema are common in smokers. The reduced immunity level causes health risks. The smokers are also prone to oral and lung cancer.


How to Avoid Tiredness Due To Smoking?

The best way to avoid the adverse effect of cigarette smoking is to quit smoking. You will find that you are receiving immediate health benefits by quitting smoking. You will find that your heart rate and blood pressure are returning to normal. The oxygen carrying capacity of blood increases due to reduced carbon monoxide level. This will help you to feel more energetic than while smoking. The blood circulation in the body improves and you will experience reduced phlegm production and cough. Your food will start smelling and taste better.

    I also get so tired after having a cigarette. Sometimes I have to take a short nap afterwards. I smoke maybe 2 to 5 a day, and its mostly in the p.m. I truly hate smoking and the way it makes me feel but at a certain point my body starts to feel hyper and I get an uncontrollable craving. I’ve tried the Gum but it is only a temp fix. If I could get the thought out of my brain I think I would be ok.

    Im done smoking, im going to meditate on it tonight.
    i find that there are many barriers in life that present itself to stop smoking.
    I dont have much reason further other than the great thought that says hey dont smoke..

    Idea is that people who try to stop and dont, want to smoke more than they dont want to.
    And so if your will to stop is stronger than your will to smoke, then you will stop.

    I think people who are starting out should go for the wind! bad advice, but hey why not, eventually you’ll figure out since you’re on this page now, you’ll sooner or later recall the idea, that hey i think i want to quit smoking.

    In the end those that dont smoke are probably taking on a healthy lifestyle which is fun to bits. more time in the end to do what we love and to live, because in the end we die and then what ? ha question raiser, but the point is the wind doesnt have worry when obstacles alter or stop its course ..so which ever choice we make we should be like the wind.. total bliss. Because stress is another killer! but if the wind did worry it would do it with love, or with hate or which ever feeling it can have, and it’s always going to be passionate about it. and just be.. the energy that it is, that it will become. A smoker will stop and the roads ahead will be a choice of now, always now.. so stop smoking…suggestion, plant it, let it grow and it will conquer.

    I stopped smoking after 29 years of smoking. Had enough of it. I stopped on the 3rd of August. Today is August 12th. No cravings, not going antsy, I’m fine with it. It is very strange. This is the first time I quit smoking and have no interest in smoking at all. I also quit drinking coffee 4 weeks ago. I usually have 4 to 5 cups at day at work. I was feeling like I had an ulcer, so I stopped drinking coffee and it worked.

      Been smoking for about 40 years! Feeling sleepy all the time and I just read on the internet that smoking causes problems with Joints and Cart ledge in your body. My knees have been getting worse now for the past 10 years. Hard to walk up and down stairs, and I am 61 years old, male. My son is 15 (yes 15) and he’s on my butt all the time about quitting and him and I are so close! I keep thinking too, all the time, if I die from smoking, he will be lost without his best friend, me. And I will Not put him through years of being lonely without me. I also have this cough and wheezing for along time too. Come to think of it, I somewhat feel Okay when I wake up each day….but as the day goes on I get sicker and the joints hurt more from smoking about a pack a day. I’m so stupid to continue this I know. I bought an E cigarette a few months ago but didn’t use it yet. And even with that I will not do that too long either! Good luck to all of you and remember as I do, we are killing ourselves and making loved ones sad.

        To Jerry. You must stop smoking. My best friend, love of my life died aged 54. He was a heavy smoker. Our youngest son misses him so much. I can’t explain my loss, but absolutely broken hearted is not even close. If only I leant on him more, but he was so fit. Stop for your sons sake as the pain your loss will be hard to bear, you should have a few more years before the Lord takes you

    I quit in Nov 2014 because I couldn’t stay awake after I had a smoke. Felt really tired and hated myself for the weakness. After that recovery was great and I didn’t feel like smoking for a year although I continued with my weekly cigar. Last week I began with a cigarette a day and the same sleepy ness took control of me. I’ve decided to leave it again. Its no fun being sleepy all the time. Life’s passing by…

    I have been smoke free for over 3 weeks now. I was a 2 pack a day smoker for over 16yrs. The older I got, the more disgusted I became with smoking. I actually woke up one morning, threw my cigarettes and all my lighters and ashtrays away, took my car to be detailed and did heavy cleaning at home. Im not going to lie, I quit cold turkey and it was hard. I found myself in the E.R. 3 times in 2 weeks. Twice for respiratory issues and breathing treatments and once for a CT a scan. They tell you the withdraws are hard, but they don’t tell you how I’ll you can become when you’re body starts healing it’s self. I was in bed for 2 weeks straight, using a nebulizer to open my airways, emotional, headaches, tired. I really honestly thought I was dying. Also anxiety sets in about a week into your process. I was thinking one minute I was having a heart attack, or I wasn’t breathing in my sleep and I literally didn’t sleep for 3 days because I was afraid I would go to sleep and not wake up. I could go on and on about the past 3 weeks of my life but I won’t bore you. All in all, my blood pressure is back to normal, my spo2 is 100%. I feel so much better, I feel ALIVE! please, whatever you do QUIT SMOKING NOW! it’s horrible for you and the people around you. Believe me, you will love yourself that much more if you do!

      Dear Meagan, You have inspired me and I am thankful you wrote what you did. Your issues parallel mine, I quit back in October of 2015, was having severe respiratory issues, in the ER twice, breathing treatments, steroids, etc. I had had enough. So STUPIDLY, I went back to smoking after several weeks, now I am sick again. I feel like a complete moron for going back to it, but the addiction calls you, but I did not have to answer!!! Now, I am quitting again, thanks to being fed up with it again, and to your posting. I don’t feel so alone anymore just knowing someone else has been as ill as I have and has finally quit. Thank You Meagan!

    Thank crap, I thought I was the only one. I’m on day 4 of quitting cold turkey. I’m 33 and have been smoking a pack and half a day for 22 years. I feel awful. I’m all stuffed up, have had bloody noses, my teeth are killing me, I’m exhausted, my chest feels like its caving in and I just want to eat everything. All the time. At least I’m not smoking ..

        Dear Candace, for some it takes a month, for others it may take a few months. It simply depends on an individual. I’ve been clean from smoking for 10 months now and it sometimes is still a battle but I feel like I am finally winning. Good luck to all of us.

    Yes the smoker feels tired. The cigarettes smoke enter into the lungs. The lungs always need the good and fresh oxygen but the smoker is not providing good oxygen to the lungs because of blockage. So smoker feel tiredness.

    Hi all,

    I want to share my expirence of quiting smoking.
    About 5 year of smoking I got week n lean.dry face and not a all looking 26 old men.
    One day I saw my face on mirror and I told myself it’s enough today it’s done no more smoking from now I spoke to myself very strongly.
    Took shower, prayer that’s it. I think you all will not belive but there was no feeling like I used to smoke I felt wow what is this. I don’t feel any cravings or side effects nothing.
    The reason for this is also wonderful I think. I went very spiritual those days. Was reading not searching Internet for spiritual things and doing lot of meditation, I was not expert but was trying anything I find. But that meditation made my will so strong that’s why it happen.
    Please try to do meditation everyday automatically u will quit the day u want to. It happen to me then why cannot on anyone we are all human only colour is diffrant.

    I’m 16 years old and just been fully diagnosed with Chronic Fatigue Syndrome. This was the worst thing I have ever faced so far. I thought I could never do normal things again, due to being constantly exhausted and never knowing when harder days would hit me. I tried so much, going gluten free, changing diet, doing more exercise etc… Then a family member said smoking makes you tired. However, I didn’t want to listen as I’ve been smoking for over 2 years and I didn’t think I had the will power to stop. But then I realised I am only 16 (nearly 17) I need to start saving for important things, E.g car stuff and essentials for when I go into Sixth Form. Furthermore, it also hit me since smoking, I’m 100% not as intelligent as I used to be and I really needed to be at my best possible health to start Sixth Form as I have a lot of pressure from my family in doing well. It’s not been long since I’ve stopped smoking but I am definitely on the road to recovery. The moral to my story is, it doesn’t matter when you start or when you stop smoking but making this life choice has a massive impact on your life regardless your age and lifestyle. Sorry this message is long, I really felt the need to tell someone to get it off my chest. Finally, one last thing, I was wondering if there are any good tips or things to do when the cravings are coming back? Thank you
