Research has indeed shown that ants sleep. However, they do not sleep in the same manner as humans. This is because ants take many micro-naps rather than uninterrupted periods of sleep each day. Within the colony, worker ants take upwards of 400 naps a day—with each nap being no longer than just a minute long. In total, worker ants sleep for about 4 hours a day. Queen ants, however, take 6-minute naps up to 90 times a day in order to get enough rest to lay eggs.
