Sleep After Exercise

Updated on January 22, 2008
J.R. asks from Bay City, MI

Is it normal to fall asleep immediately after exercising? This has happened all my life, to become really sleepy afterwards. However lately after walking on the treadmill after 30 minutes I literally feel drugged and have fallen asleep for 3 hours. Everyone tells me I'm suppose to feel energized, but I'm ready for the nearest couch and pillow. I am a normal active person, playing softball in the summer and participating in local 5K walks...so I'm not a couch potato.
Also, I'm wondering if it has become more extreme due to being on blood thinners. I had an Pulmunary Embolism in October and have been on the thinners since. What are your thoughts? Is this normal?
Thanks

Jodi,

I would get your thyroid checked. I used to feel like I wanted to hybernate, I had other symtoms too from not knowing about hypothyroidism. I was cold all of the time and I was gaining weight even though I was exercising. Mine went unchecked for a long time, so I even began losing my hair. It is a simple blood test to have it checked and all you do is have to be on a pill for it. Hypothyroidism is very prevelant in women - especially those who have given birth. It isn't a big deal unless you let it go unchecked. I am sorry I don't know anything about blood thinners. S.

From the perspective of a medical provider, you need to see your doctor! The list of possibilities is endless and rather scary. Had a check up lately?

That happens to me every time I exercise in the morning, and when I wake up, I'm a grump all day!

This completely stopped when I started working out between 4-7P.M.. My doctor said some people just aren't morning athletes because my blood glucose is too low and it takes so long for my body to gear up after eating in the morning.

Try exercising at another time of day. See if that works. Also try to eat a bit about an hour before you exercise so it gives your body time to get the energy out of it. Good luck!

I have this exact same problem. If I hop on the elliptical for a quick work out, once I am done my pillow is my best friend. Because of this, I use it at night before bed. I do not take any blood thinners, but am on medication for high blood pressure. I have always just attributed it to being just the way my body reacts. I am not grossly overweight, but would like to lose 10-20 pounds after having child #2 and like you, the work out puts me right out. I'd be interested to hear what you find out from a dr. because I guess I never thought of it as an issue for me, just being in not-so-great of shape and the body needing to restore the oxygen I just spent, but maybe it's more than that. Please let us know what you find out if you consult your dr and I'll have to ask next time I'm in myself...

Go to: www.mercola.com. Type in the search: Blood thinners.
Mercola is a medical doctor that is fighting for the health of people and prevention of diseases. I have learned a lot on his site. Don't just listen to one doctor. Be responsible for your own health and get 2nd opinions. Research and educate yourself on the drugs you take. Discuss what you find with your doctor. He is working for you. You pay for his mansion and expensive cars. Doctors do make boo boo's at times. You should have a voice in your health. Hope you find the treasures you need to live a healthy life. A.

I was reading through the responses and one individual's response mentioned that you might not be getting enough oxygen to your brain and body. I was experiencing tiredness and other symptoms that were really starting to bother me. I thought it was my thyroid but turns out I am B12 deficient so I now get monthly injections because my body is unable to absorb B12 from foods. B12 is needed in the body to carry oxygen through the red blood cells to the brain. You might also want to get your B12 levels checked.

I'm like this too. I've been told it's because I have really low blood pressure & there's supposedly nothing they can do about it at my age. I also was told by a trainer if you overwork yourself (i.e. watch your heartrate) that you can become very tired after working out.

You mention you do 5K walks & play softball, do you also feel tired after those? If not, I'd really pay attention to that heart rate

My first thought is to ask are you feeling short of breath at rest? When you had the PE did they test your lungs to see if they are functioning at full capacity?

Also, I definitely think the blood thinners could be playing a role in how you feel. I assume you're getting your blood drawn regularly to make sure your PT/PTT levels are okay. If you're really that tired it sounds to me like for some reason you're not getting enough oxygenated blood to your brain and body. When is the last time you had your hemoglobin checked? When you're on blood thinners you're at risk for bleeding easily. Are you looking kind of pale?

I'm sorry I'm asking so many questions - but it sounds like this is an excellent question for your doctor! You need to follow up on this.

I think you are getting some great advice. Your blood thinner is probably playing a part. It may also make you a bit anemic, so I would try some iron. Also, I would try eating protein after your workout (even if it is just a spoon of peanut butter or a protein drink you can get from GNC or some other nutritional store, I like apex's product). Your muscles cannot rebuild and your body cannot recover if you do not get some good protein within an hour after working out. It could be that your muscles just don't have the nutrients they need to recover.

You should absolutely discuss this with your doctor. I don't know if this could possibly be normal, or if perhaps this is a sign of anemia, or if there is something else to blame. However, since this has worsened since being on blood thinners, you should bring this up to your doc.

Jody, It sure sounds like something is off. I'd definately go see your Dr. asap. This may be a sign of something that you don't want to put off correcting.
I get sleepy during the day almost every day. But, I have something called hypothyroidism, which has that effect, sometimes even on meds. But, I have to say that when I exercise, I don't feel sleepy afterwards. So, while it might be a good idea to check your thyroid out, this sounds more drastic than that.
I also have used a baby aspirin daily to help my periods, and they haven't ever made me feel too tired. But I don't know what kind of thinners you are on.
You aren't going to know for sure what is happening unless you get to the doctors. Please don't put it off. This is no way to live well. Hugs, and hope to you for an answer.

from what i have read online, it really depends on what kind of blood thinner you are on. NSAIDs. now i take naproxen, and it says right on the bottle it can make you drowsy. but the thing i'm curious about, should you be doing any exercising at all while being medicated? have you talked to your doctor about this? did this ever happen to you before you took the blood thinners after exercising? i highly recomend calling your doctor, especially if the bottle doesn't mention drowsiness. he/she gets paid to help you, let them do their job. i would appreciate it if you would let me know what they say. good luck and i hope everything works out for you!
