These days, I feel a little tired when I wake up in the morning although I don't know why.
It was quite hard to wake up in the morning, even though I didn’t drink last night or go to sleep late.
So, I asked my colleagues or clients about this matter.
They also feel the same way these days.
So, I think that one of the causes is the extreme change of the weather.
Now, it is the transition of summer to autumn.
So, the gap of the daily temperature is so big.
It is quite chilly in the morning and night, but it’s still hot during the daytime.
Since we feel cold in the morning, we don’t like to get out of our warm beds.
We need some time to adapt. |
