Every person, animal, living creature has body functions that are controlled by internal cycles. Many of their functions are controlled differently than others. Most that function on circadian rhythms tend to be less active during the night and more active during the day. For example, many “species are remarkably diverse and flexible in their daily activity patterns, including a spectrum of diurnal, day-active, to nocturnal, night-active” (Phillips 2013). Birds fly, eat, etc. during the day and sleep at night. Then again there is the owl which is the opposite. They sleep during the day and perform actively during the night. Likewise, humans function on circadian rhythms like many animals. “Our bodies are verified to have a regulatory mechanism …show more content…

This is because during the day everyone is active and at sleep well everyone’s is resting (Fig. 1). The highest heartbeat was 74.82 during the day at 6pm and the lowest heartbeat was 64.55 at 4am. In the eye-hand coordination exercise students took longer in the morning and were faster in the middle of the day (Fig. 2). The longest time was 9.41 seconds at 6am and the fastest time was at 4pm and took 6.56 seconds. Also the amount of mistakes done by students in this same exercise was a little alike to the previous observation (Fig. 3). The most mistakes were done at 6am with 1.23 mistakes and the least mistakes were done at 12pm, 1pm and 12am with only .41 mistakes. Finally, in the adding exercise students adding skills were slower in the middle of the night and faster in the afternoon (Fig. 4). The slowest time taken to add was 69.91 at 4am and the fastest time taken was 55.99 at …show more content…

Circadian rhythm mainly presents in sleeping, feeding patterns and other activities. These patterns will be disturbed when circadian rhythms changes (Guo 2013). For example, in the eye-hand coordination exercise students took longer in the night and were faster during the day (Fig. 2). This is reinforced by studies (Boudreau 2013) that show how people work less efficiently when circadian rhythms are interrupted. In addition, in the adding speed function (Fig. 4), students performed slower at night but gradually faster during the day. This is supported (Phillips 2013) in where everyone is remarkably diverse and flexible in their daily activity
