When do hibernating animals usually wake up?

First, animals hibernate at different times and wake up at different times. Most animals wake up automatically in this solar term, not because the solar term is going to come out for activities, but because the temperature in this solar term has warmed up and reached the awakening temperature.

Second, the hibernation of animals is completely a protective action against the bad environment. The main factors leading to animal hibernation are the decrease of environmental temperature and the lack of food. After hibernation, the ability of animals to resist bacteria and diseases is enhanced than usual. Obviously, hibernation is good for them, which makes them more sensitive and have a bigger appetite when they wake up the next spring.

Extended data:

Animals hibernate:

(1) Hibernation is an extreme but regular decline in body temperature, metabolism and other physiological activities, which is an adaptation to reducing energy consumption. This definition does not include seasonal or day and night dormancy of temperature-changing organisms in passive response to environmental temperature reduction. Therefore, true hibernation is limited to birds and mammals.

(2) Hibernating species can be roughly divided into active hibernating animals and passive hibernating animals. The latter, such as hamster, external factors, including photoperiod, food and external temperature, play a major role in the timing of this hibernation cycle event.
