How Do Flies Sleep?
WouterUnlike humans, flies do not require a regular sleep schedule. They sleep only when they need to and will find a warm, comfortable place to sleep. Most flies sleep during the night, but they can also take a short nap during the day. The length of sleep depends on the amount of energy that flies use during the day.
The researchers used the Drosophila Activity Monitoring (DAM) system to study the sleep patterns of flies. The system allows researchers to load flies into individual tubes and place them in a machine that measures when an infrared beam is blocked by the fly. This process allows scientists to analyze sleep patterns and determine the length and number of sleep bouts. The team says that the study could have implications for people who struggle with their sleep habits.
Flies sleep by building up a protein that helps them function better in dark conditions. They then break down the protein when exposed to light. It is similar to the proteins that humans use to sleep. Flies also respond to the effects of stimulants that keep us awake. Some alcoholic beverages and antihistamines can alter their sleep patterns.
Unlike other animals, flies sleep more deeply than most other animals. However, they will wake up when predators approach. They also take naps daily, ideally in shady areas where they can avoid the heat. If they sleep on the ground, they risk being eaten by hungry animals. Additionally, flies sleep upside down to avoid the heat of the day.
