Explanation:

Circadian rhythm is a natural, internal process that regulates the sleep-wake cycle. It repeats that cycle on each rotation of the Earth every 24 hours. It has been said that if your circadian rhythm is out of weight can cause weight gains, impulsivity, slower thinking, and other behavioral changes it is similar to those who experience jet lags and work shifts.

Hope this helped :)  

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
