It will take you at least a day to recover from daylight saving
Daylight saving is coming. Body clock scientists tells us that shifting our sleep cycle by one hour will take us at least one day to adjust. Imagine what happens when we socialize for just a few nights every month.
It takes longer than you may imagine for your body to adjust o even the smallest glitch in your circadian rhythm. For example, one night of shift work can throw off your circadian rhythm for an entire week. Cross-country travel may seem benign, but when you have to adjust to a new time zone, you may feel jet-lagged for a few days. For most people, our circadian clock takes almost 1 day to adjust to each hour of time zone shifting; for some people, it can take 2 days per hour of time shift.
Similarly, when you stay awake for 3 extra hours and delay your breakfast by 3 hours on the weekend, it affects your body in the same way as flying from LA to New York. That’s why partying or staying awake late into the night is the same as flying over a few time zones; hence body clock scientists call this habit “social yet lag”. http://ow.ly/i/IHIFN
