Bees are fascinating creatures, and their sleep habits are no exception. While it may not be common knowledge, bees do indeed sleep, and understanding their sleep patterns offers insight into their daily lives and the crucial role they play in our ecosystem. So, do bees sleep during the day, or do they follow a different schedule altogether? Let's explore the sleep patterns of these hardworking pollinators and uncover the unique behaviours they exhibit when they need some rest.
| Characteristics | Values |
|---|---|
| How much do bees sleep per day? | Between 5 and 8 hours a day, similar to humans. |
| How do they sleep? | Bees take several "naps" within a 24-hour period. |
| How do they sleep? | Their antennae, upper body and abdomen droop down, and their wings rest against their bodies. Some bees fold their legs beneath their bodies, and other bees may hold each other’s legs while sleeping. |
| Where do bees sleep? | Bees sleep in the hive, on flowers, and even on walls. Females typically sleep inside the nest, whereas male bees are more likely to be found sleeping outside. |
| What happens when bees are sleep-deprived? | Their communication skills are impaired, and they need to be excellent communicators to signal to others where the best food resources are located. Sleep-deprived bees may also get lost on their way back to the hive. |
| Why do bees sleep at night? | Foraging typically takes place during the day. Most flowers are open during the day and a bee’s vision is at its best during daylight hours. |
| Do bees' body temperatures change when they sleep? | Yes, their body temperatures lower when they sleep. |
| Do bees wake up to light? | Bees are naturally awakened as darkness ends and the sun rises higher in the sky. However, bees in a deeper state of sleep require a more intense light source to respond and wake than bees in a lighter sleep stage. |
What You'll Learn
How do bees sleep?
Bees do sleep, and they do so in a variety of ways and locations. They may sleep at night or during the day, depending on their age and role in the colony. Forager bees, which are older bees, tend to sleep in day-night cycles, with more sleep at night when darkness prevents their excursions for pollen and nectar. They sleep in the hive but may also sleep in flowers. Young bees, on the other hand, sleep for shorter periods and do not follow a day-and-night rhythm. They sleep closer to the centre of the nest, near the developing brood, and can also be found sleeping inside cells.
When bees sleep, they adopt a relaxed posture, and their temperatures lower, which means they will not respond quickly to disturbances. Their legs start to flex, and they bring their heads down towards the floor. Their antennae stop moving, and they may even fall over sideways if they are very tired. Some bees hold each other's legs while sleeping, while others fold their legs beneath their bodies.
Bees sleep for a few minutes to several hours at a time, and they do so in a variety of locations, including the middle of a flower or on a wall. Females typically sleep inside the nest, while male bees are more likely to sleep outside. Honeybees sleep between five and eight hours a day, taking several "naps" throughout the day and night.
Sleep is important for bees' memory consolidation and communication skills. Without enough sleep, bees' communication skills are impaired, and they may waste time and energy searching for food sources. Sleep also helps bees learn new routes back to the hive and solidify information acquired from other bees.

Where do bees sleep?
Honey bees sleep inside their hives, taking several "naps" within a 24-hour period. The location of their sleep depends on their role in the colony. The younger house bees sleep closer to the centre of the nest, near the developing brood, and in areas where they need to deal with cells that store honey and larvae. They can also be found sleeping inside cells, though this is more common among the lowest caste in the hierarchy—the cell cleaners.
Older worker bees, or foragers, sleep outside cells and nearer to the perimeter of the nest. The noise and activity nearer the centre of the hive make it harder for them to get the restful, energy-restoring sleep they need for a demanding day of foraging. Sleeping near the perimeter allows them to rest mostly undisturbed and get better-quality sleep.
Female solitary bees sleep in their nests, while male solitary bees sleep outside, resting in places like grass stalks or flowers.

How long do bees sleep for?
Bees do sleep, and they do so in a way that is different from humans. They don't sleep in one continuous stretch but take several "naps" within a 24-hour period. The number of naps depends on the bees' caste and age. Forager bees, the oldest bees in the colony, take around 50 naps, while younger bees take about 40.
Older bees exhibit a more well-defined sleep pattern than younger bees. Once they wake up, they will be active until their day's work is over, usually around sunset.
It is difficult to say exactly how long bees sleep, but older bees catch between 30 minutes and an hour and a half each night. They do this by taking little sleeps, or catnaps, of about 15 to 30 seconds at a time.
Bees sleep in different locations depending on their role in the colony.

Older worker bees, or foragers, sleep outside cells and nearer to the perimeter of the nest. This is because the noise and activity nearer the centre of the hive make it harder for them to get the restful, energy-restoring sleep they need for a demanding day of foraging.
In cumulative hours, honey bees sleep between five and eight hours a day, which is similar to humans.

Why do bees sleep?
Bees sleep for a number of reasons. Firstly, they need to rest and recover from their busy days of collecting nectar, building, making honey and protecting their queen.
Secondly, bees need sleep to help with memory consolidation. Studies have shown that bees that fall into deeper sleep states recall relationships between food and certain odours better than bees that don't.
Thirdly, bees need sleep to communicate effectively. Sleep-deprived bees have impaired communication skills, which is a problem when they need to signal to other bees where the best food sources are located. For example, a sleep-deprived bee might perform the 'waggle dance' (which directs bees to food sources) inefficiently, causing other bees to waste time and energy.
Finally, bees need sleep to be able to learn new routes back to the hive when they are visiting new flower patches. Without sleep, they may get lost trying to find their way home.
Bees sleep between 5 and 8 hours a day, but they don't sleep in one continuous stretch like humans do. Instead, they take several 'naps' throughout a 24-hour period. The number of naps they take depends on their caste, with forager bees taking around 50 naps a day and younger bees taking around 40.
Bees don't follow a specific sleep rhythm, and their sleep patterns depend on their role and age. For example, forager bees tend to sleep in day-night cycles, with more sleep at night when they are prevented from flying out to collect pollen and nectar. On the other hand, younger bees sleep for shorter periods and don't follow a day-night rhythm.

Why is bee sleep important for humans?
Bees are some of the hardest-working creatures in the world. In a single day, a bee can visit more than 1,000 flowers to extract nectar and pollen, which it then brings back to the hive. For solitary bees, the work doesn't stop there, as female bees need to defend their own nest, lay eggs, and feed the offspring without any help. In social and colony-forming bees, the division of labour is prominent, and each bee takes on a role, specialising in one task.
Bees are essential not just for the well-being of ecosystems but also for human activity. Insect pollinators, including bees, contribute to our economy. Bees play a crucial role in agriculture by pollinating farmers' crops and providing us with food. Researchers from the University of Pittsburgh and Penn State University quantified that the economic value of bees totalled $34 billion in 2012, and this figure has only grown as agricultural practices have intensified.
Therefore, bee sleep is important for humans because bees need sleep to function well, and we need bees. When bees are sleep-deprived, they function significantly worse in key aspects. For example, they are unable to perform the waggle dance properly, and they have difficulty learning new routes home.
A study from the University of Bristol revealed that bees are currently experiencing alarming levels of sleep deprivation, and humans are to blame. Their lack of sleep is caused by the pesticides we use. Chemicals used in commercial pesticides disrupt the body clock of bees, resulting in them foraging less and sleeping more during the daytime. This has cascading effects on the bees' health. If bees go out more at night, they will not be able to collect food as flowers are not available during this time, which will affect their colony's health as nectar and pollen are vital for growth and reproduction.
Additionally, sleep-deprived bees have decreased precision in performing the waggle dance, a well-known communication strategy used to signal to other bees the direction and location of food sources. With almost 90% of wild plants and 75% of global crops depending on bees, the decreased efficacy of their pollination will have disastrous ecological and economic effects.
