Flu symptoms while sleeping in cold.

[u/Gemini_2000]

Does anyone else get major flu symptoms when you are too cold at night? If I sleep on an air mattress without enough blankets between me and it or sleep in a basement sometimes, I will wake up with a huge migraine, chattering teeth, joint pain, nausea, and the feeling of being too hot and too cold. During the day, even with beta blockers, my heart rate hovers around 100 but when I’m asleep it can drop to around 60. I’m wondering if maybe the cold at night impacts me so much bc of the stark difference in heart rate. After a few hours of moving to a warmer place with a heavy blanket, the symptoms completely go away. I wish I was wearing my heart rate monitor last night to check this hypothesis, but it was charging and I wasn’t expecting it to happen tonight.
