Exercise and sleep apnea.

[Yayoe10]

Ive noticed every time I have a intense work out and feel sore and tired from it already at night , when I wake up the next day my AHInare always high. Not a drastic "high" but I get a change from 0.8-1.3 to a 3.5-4.5 and I can FEEL the difference which sucks because other people get way higher numbers so I should be happy with mine but i always feel way better with numbers before 1.5 especially below 1. But yea my question is can working out actually increase my AHI? I thought it was suppose to be the other way around .

[Pugsy]

What is the higher AHI night (after the workout) made up of?
If it is more centrals/clear airway events it could simply be that you aren't sleeping quite as soundly due to the soreness and you are having more awake/semi awake events.
Or maybe you are so tired that you sleep deeper and maybe get more REM and if your OSA is worse in REM...maybe more REM equals more OAs.

When comparing one AHI night to another AHI night you always have to look at the category of events in addition to the overall AHI number ...which category increased on the higher AHI night.

Ive noticed every time I have a intense work out and feel sore and tired from it already at night ,

1. How many hours between finishing your workout and going to bed?
2. How old are you?
3. How often do you work out?
4. What fraction of your workouts are these intense ones?
5. Why do you do such an intense workout that you are so tired and sore by night?
6. What are the goals that you hope to achieve with intense workouts?

those people with higher numbers may "get away with it" but they'd feel better with lower numbers.

I feel worse if my AHI is over 1.5-2, face it, higher numbers mean less good sleep.

I agree with ChicagoGrany. Do your exercise earlier. You're doing it too close to bedtime.

Possible vitamin D deficiency?

I have the same issue with exercise. I tend to mouth breathe more. I drool significantly more on my pillows and sleep worse. It may have to do with the way exercise changes the way you normally sleep. Exercising tends to make you sleep deeper and might cause your muscles to relax even more

If you are sleeping more deeply, you may need more pressure on those nights. Are you using straight cpap or an auto range? If you have a range, look at your graphs and see if the pressure is going up more.

I know that when I use a muscle relaxer, I need more pressure. My auto range is already set well enough to handle that, so I don't have to make any changes. BUt I can see that the machine used more pressure on those nights.

This is odd for a while I thought my morning exercise may have been lowering my AHI
that night. But something wlse may have been doing that, the something being that
days I exercise I almost always tend to overeat. And at least for me eating a lot of carbs
makes my AHI lower that night. Ok not a good way to lower your AHI and counter productive
to say the least but take this example.

I picked up my new DreamStation Auto 2 weeks ago and after using it in cpap mode the first
night switched to auto. At that time I was eating a high carb diet. My first night my AHI was 1.86
the next night .93 . Then I started a low carb diet and my average AHI the past 12 days I have
been on it has been about 2.4 and only once did I get as low as .98 . I haven't been exercising
recently but may start back and see how it affects my AHI while I am doing low carb.

... depends on the source of your carbs.

I agree with ChicagoGrany. Do your exercise earlier. You're doing it too close to bedtime.

I never said he should do his exercise earlier.

I never said he was doing it too close to bedtime.

Go agree with someone else. Palerider, for example.

This is an old thread but i know why you need more pressure on days you exercise. Yes you do sleep deeper probably but the main reason is that your metabolism is increased for a good 24 hours if not 48. It is not true to assume that within a couple of hours everything is back to baseline. Therefore, your breathing is a lot more deeper regardless of your sleeping or not but especially when you sleep since your body takes over and needs a constant higher airflow from those deeper breaths. I realized that when i increased the pressure on days i work out, the same pressure that was too high on days i am deconditionned is now perfect and i take in a lot more air and it feels way more comfortable. You will have to adjust the pressure yourself on days you exercise by at least an extra cm. Dont let the auto feature do it for you as it does not account for baseline and will only adjust sporadically throughout the night. Also keep in mind that if you take a few days off from exercising, chances are that pressure will be too high and you will need to adjust and lower it again. It's more of a hassle but it really works. Good luck!

CPAP works by splinting the airway open with pressure. For your explanation to be credible, it would need to explain why the airway is more easily collapsible on days of heavy exercise.

The OP never followed up on the thread. In the meantime, Pugsy's two possible explanations seem to be in the correct set.

Well, it's implied. The AHI is increasing because the pressure is too low ( due to an increased demand from the lungs for more air intake, due to metabolism change for the 24-48 window following exercise) Therefore the pressure is not sufficient, therefore the airways collapse. Sorry for not specifying that part however it is implied. Mind you, i am not saying it's the sole reason but overall its the underlying reason, whether sleep stages(REM) or depth of sleep make up for the AHI fluctuations, it's all predominantly based on the body's oxygen needs depending on demand/metabolism

[Goofproof]

And that's why one of the reasons they came up with APAP's, when properly set up, they will cover the increase. Jim
