I couldn't exercise early in the morning due to a cold, and I kept sleeping during the day, so I can't fall asleep.

I originally had insomnia, but I used to sleep early at night while exercising. However, yesterday I was running in the cold during early morning exercise, and since I sweat when I run in the cold, I went out wearing a short-sleeved shirt and got caught in the rain, which made me catch a cold.

So today I couldn't even go for a run and just collapsed and kept sleeping, but I can't fall asleep. To sleep well again, I should go for a run once it gets light.

The temperature difference between day and night is severe, so everyone please be careful of colds.
