Re: Anyone wake suddenly fr sleep choking/coughing, hands shaking, which sends u into
The sensation of choking while in the hypnogogic period between wake and sleep is most commonly due to a sleep apnea event. There is often confusion and the sensation that swallowing is difficult, or alternatively suffocation. A startle effect usually follows and panic sets in because of concern that something is going terribly wrong. Many persons quickly proceed to get water or something to drink, mainly to convince themselves that nothing is actually blocking their airway and that the swallow response is actually functioning properly. After several minutes, self-resolution typically reduces fear and a return to normal status is experienced.
The mild tremor in the hands or arms is an entirely normal response to such an event and is merely a byproduct of the fear response and an epinephrine (adrenalin) spike.
These events are most common in persons susceptible to sleep apnea who predominantly sleep on their back, even moreso when multiple pillows are used to prop the head in a more forward direction while lying down. Even so, the events do occur in persons sleeping on their side, more rarely lying on the stomach.
You'll be fine. If the symptoms increase in frequency, you can speak to your primary care physician about a formal sleep study.
