日本とニューヨークでは朝と夜がひっくり返るため、ニューヨークから帰ってくると時差ぼけがひどく２、３日は夜は眠れず、昼間に眠くなる。あと頭はそれほど眠くないのに、体が眠くだるい感じ。
Since morning and night flip over between Japan and New York, I get very bad jet lag when I come back from New York. I can't sleep for a couple of days and get sleepy during the daytime. Moreover, my body seems very heavy and sleepy even though my brain doesn't feel that sleepy.
