What is the best AC temperature for good quality sleep? Medically reviewed by Debra Rose Wilson, Ph. Other circadian bodily processes, like cell function, can also affect how medication acts. Early research suggests certain drugs—including some for colorectal cancer, pain and asthma—perform better or are less toxic when taken at different times of day.
Exercise, which can be as powerful as medicine for some conditions, is good for you whenever you do it. In one small study published in in the journal Diabetologia, Zierath and her team started 11 men with Type 2 diabetes on a high-intensity interval training program. The men exercised either in the morning around 8 a. The researchers expected that regardless of the time of day, men in both groups would see improvements in blood-sugar levels. Scientific knowledge is nascent when it comes to optimizing testing and treatment by the clock.
Our understanding of individual circadian time is even more primitive. For now, even the understanding that our bodies often operate according to different clocks is a big scientific advance.

By Mandy Oaklander. Already a print subscriber? To investigate why some people need a nap, genetic information from , people was analysed by researchers. Some were also asked to wear an activity monitor, or accelerometers, to make sure they reported their snoozes accurately.
A genome-wide association study GWAS was then carried out to identify genetic variations associated with napping. GWAS identified regions in the human genome, which were associated with having a sleep during the day. A large number of these regions were already associated with snoozing, which reassured scientists they were on the right track. Digging deeper into the data, they identified three potential napping mechanisms.
The first two, dubbed "disrupted sleep" and "early morning awakening" refer to people who nap because they haven't had enough shut eye the night before, or because they get up very early in the morning.
