Researchers have identified a gene in fruit flies that suppresses the urge to take afternoon naps.
The 'daywake' gene overrides the fly's in-built desire to take an afternoon nap to avoid expending energy during the hottest part of the day.
Siestas - Animals - Humans - Energy - Cooler
Siestas can be beneficial for animals and humans as it saves energy, but in cooler weather it is more productive to stay awake.
In the case of the fruit fly, the gene activates to suppress the flies' tendency to take a daytime nap - allowing them to spend additional time seeking food or mates.

The discovery sheds light on the biology that helps many creatures balance the benefits of a good nap against getting important activities done during the day.
Scientists examined the genome of the fruit fly and discovered a gene that is activated when temperatures are cooler.

The researchers, from Rutgers' Center for Advanced Biotechnology and Medicine, found the 'daywake' gene activates when temperatures are cool, which suppresses the flies' need to take a nap.
