I have been experiencing breathlessness for a few mornings - it goes off later in the day.  I am at a fairly high altitude (6000ft) but have been here for a couple of weeks.  I havent slept particularly well for a few nights because of noisy neighbours.  Im 57, reasonably healthy although I could do with losing 15 pounds, female. No pain and no other symptoms.
Hi, If you experienced breathlessness after you didn't sleep well for a couple of days, then it is relayed to it. Don't worry, just regulate your lifestyle, and it will disappear, otherwise see a doctor to perform chest X-Rays if you continue to have further breathlessness. Take care
