Poor circulation in hands while asleep

Hi.  I'm a 40 year old female and have begun some light weight training during the last two weeks.  I've mainly been doing high reps with low weights with some cardio for about 40-50 minutes a day for 3-4 days a week.  I've done this type of workout off and on since my 20's.

Last night while I was asleep my hands took turns going numb.  I woke up at least twice with one of my hands 'asleep'.  This morning they are both a little weak and tingly.  I'm wondering if yesterday's work out caused this to happen.  

Does anyone knows what might cause this?

whenever we do some new and additional work out,many a time we encounter some symptoms like pain, tightness or vibrations, numbness and swelling including tingling. I did vajrasan ( a yoga posture for years for 15 minutes after each meals) This resulted in tightness of feet. Doctors label it as parasthesia. Pathology is not known. So there is no treatment. I had tingling of hands and feet, few years back. All tests came negative. However, I stopped new work out and it helped me in stopping tingling. I am 80 so I do expect some problems when adding new exercise.

Hi there!

Well, it may not be abnormal to wake up in the middle of a sleep cycle to experience weakness of limbs. This happens normally during phases of the sleep cycle due to loss of muscle tone. However, if the weakness continued into the day, there could be a few possibilities to it. Excessive amount of workout may lead to accumulation of lactic acid, which is experienced as painful stiffening of muscles with some amount of weakness. If its just plain weakness, it could result from neurological or muscular disorders or could be a TIA/ mini-stroke. I would suggest getting this evaluated by a neurologist at your earliest convenience. After a diagnosis is made, an appropriate management plan can be drafted accordingly; if required.
Hope this was useful.

Take care!

I was going to suggest it was a lactic acid build up, but the Dr. above has already mentioned that. Are you taking a decent daily multivitamin/mineral that has potassium and adequate levels of B vitamins? They're both needed for healthy function of nerves and muscle movement, so if you're deficient it could manifest itself as numbness/tingling (that's nerves) or weakness/cramps/spasms (that's muscle).
Hope you get it sorted and feel better soon!
