What could be causing me to have panic attacks in the middle of the night?

Day panic attacks: Most patients that have panic attacks at night have them during the day. Most people describe that the panic attacks at night are very similar to daytime panic symptoms. If they are not, it could be that other sleep disorders like sleep apnea, which can cause breathlessness, heart racing could be the culprit. Would optimize treatment of panic attacks and maybe see a sleep specialist.

Panic at night: Large no. Of panic attacks occur late in the day when u r less physically active & your body is accumulating more adrenaline to the point that an attack is triggered.
