What are the differences between hibernation and sleep?
The difference between hibernation and sleep lies in the definition and concept, physiological process, brain electrical activity, physical performance and length of time. Detailed introduction: 1. Definition and concept. Hibernation refers to a biological response. When environmental conditions are not suitable or resources are insufficient, organisms will enter a dormant state to save energy. The metabolic rate of the organism decreases, the body temperature drops, and the breathing and heart rate slow down. , entering a state similar to hibernation. Sleep is a cyclic physiological state. Humans and other animals will enter an unconscious resting state during sleep. The human brain activity slows down, muscles relax, etc.
The operating system for this tutorial: Windows 10 system, DELL G3 computer.
Hibernation and sleep are two different concepts, and they are physiologically and functionally different. The difference between hibernation and sleep will be introduced in detail below.
1. Definition and concepts:
- Hibernation: Hibernation refers to a biological reaction. When environmental conditions are not suitable or resources are insufficient, organisms will enter a dormant state to save energy. In the dormant state, the metabolic rate of the organism decreases, the body temperature drops, the breathing and heart rate slow down, and it enters a state similar to hibernation.
- Sleep: Sleep is a cyclic physiological state. Humans and other animals will enter a state of unconscious rest during sleep. During sleep, the human body's brain activity slows down, muscles relax, and consciousness and perception are reduced.
2. Physiological process:
- Hibernation: Hibernation is a physiological response to adapt to the environment, which generally occurs under conditions that are unfavorable for survival such as low temperature, drought, and food shortage. In the dormant state, the metabolism of organisms slows down and energy consumption is reduced to keep life activities to a minimum.
- Sleep: Sleep is a physiological process and a natural physiological need of the human body. Sleep is controlled by the regulation of neurotransmitters and hormones in the brain. During sleep, the human body goes through multiple sleep cycles, including light sleep, deep sleep and rapid eye movement (REM) sleep.
3. Brain electrical activity:
- Hibernation: In the dormant state, the brain electrical activity of living things slows down and shows lower electrical activity.
- Sleep: During sleep, the human body's brain electrical activity will change and go through different sleep stages. During light sleep, brain electrical activity is fast and irregular; during deep sleep, brain electrical activity is slow and regular; during REM sleep, brain electrical activity is similar to the waking state.
4. Physical performance:
- Hibernation: In the dormant state, the body's physical activities slow down, the body temperature drops, breathing and heart rate slow down, and muscles relax.
- Sleep: During sleep, the muscles of the human body relax, breathing and heart rate slow down, the body temperature drops slightly, and the eyeballs move rapidly.
5. Length of time:
- Hibernation: The length of hibernation can be from a few days to a few months, depending on the adaptation of the organism to the environment.
- Sleep: The length of sleep is usually a daily cyclical behavior, adults need about 7-9 hours of sleep, while babies and children need more sleep time.
To sum up, hibernation and sleep are two different concepts. Dormancy is a physiological response of organisms to adapt to the environment, which occurs when environmental conditions are unsuitable or resources are insufficient to save energy. Sleep is a cyclic physiological state and a natural physiological need of the human body. It achieves rest and recovery functions by regulating brain electrical activity and physical performance. Although hibernation and sleep share some similarities in some aspects, they have clear differences in their definitions, physiological processes, brain electrical activity, physical manifestations, and duration.
