How Do Snakes Survive the Winter? Understanding Snake Overwintering Methods in One Article

Snakes are not commonly seen in daily life, and generally friends who live in commercial housing basically find it hard to even come face to face with one. But we all have some understanding of them, so how do snakes survive the winter? Let us take a look together!

1. How Do Snakes Survive the Winter

When winter comes, snakes enter hibernation. It takes about three months from entering the burrow to the hibernation period, and they mainly rely on nutrients stored in the body in the form of fat for slow replenishment; in this way they maintain their minimum living nutritional supply. 

2. Snakes' Living Habits

1. Snakes are a type of ectothermic animal whose body temperature changes with air temperature, because snakes themselves do not have a complete thermoregulatory mechanism to generate and maintain a constant body temperature.

2. The most suitable temperature for snake activity is 20~30°C, and within this suitable range the growth rate of snakes also rises in a straight line as the air temperature rises. For example, one study found that at temperatures of 18°C, 23°C, and 28°C, the monthly weight gain of adult cobras was 64.7, 72.7, and 94.3 grams respectively (the difference is even greater for young snakes). But above about 35°C they will lose their appetite and become ill, and above 40~45°C they die rapidly.

3. Air humidity also has a great influence on snakes, generally with 50~70% being suitable. If it is too high, they are prone to mold spot disease, pneumonia, and so on, with a relatively high mortality rate in the south; if it is too low (for example, during the spring drought period in the north), then because water evaporates too quickly it is not conducive to molting (especially for pregnant snakes), affecting their continued growth and even causing death. “When snakes cross the road, heavy rain is coming” is also the result of low air pressure and high humidity before rain, which makes snakes feel uncomfortable and run around everywhere.
