How cold is too cold for cabbage?
Cabbage. Cabbage likes cool temperatures as low as 26 degrees depending on the variety. In fact, you will find they do best in cool fall weather and are rather disappointing in a summer garden. However, if you start them early enough, you can still get a crop before the weather gets too hot.

- Turn down the thermostat. Slowly start decreasing the temperature in your house to a level you can tolerate. ...

- Drink ice-cold beverages regularly.
Frost Hardy
Among the hardiest vegetables are cole crops, which can tolerate moderate (24-28°F) freezes: Broccoli; Cauliflower (26°F) Chinese cabbage; Cabbage; Kale; Kohlrabi; Turnip.
Sensitivity to the cold; Intolerance to cold. Cold intolerance is an abnormal sensitivity to a cold environment or cold temperatures.
Our study suggests that genetic changes caused by the loss of alpha-actinin-3 in our skeletal muscle affect how well we can tolerate cold temperatures, with those that are alpha-actinin-3 deficient better able to maintain their body temperature and conserve their energy by shivering less during cold exposure.
Growing Temperatures
The optimum temperature for growing a successful cabbage crop is 60 to 65 degrees Fahrenheit. Cabbage will grow at temperatures as low as 45 degrees and can tolerate high temperatures up to 80 degrees, but if it gets any warmer, cabbage will bolt.
For plants that can survive a light frost, add a heavy layer of mulch to keep the ground around them from freezing. You can still harvest late into the fall as long as the ground isn't frozen. These veggies include: beets, broccoli, cabbage, celery, lettuce, parsnips, arugula, swiss chard, and other leafy greens.
Old blankets and sheets are a great way to protect plants from frost. The blanket will help insulate tender plants and keep them alive during a frosty night. Use stakes or hoops to hold the material up and away from the foliage and drape the blanket over the plants until it touches the ground.
Aging causes a natural decrease in metabolic rate, which means seniors' bodies might be unable to generate enough heat to maintain a "normal" temperature of 98.6 degrees. Slower circulation can make it difficult to retain heat throughout the body. This could be due to aging or medication side effects.
Hospitals combat bacteria growth with cold temperatures. Keeping cold temperatures help slow bacterial and viral growth because bacteria and viruses thrive in warm temperatures. Operating rooms are usually the coldest areas in a hospital to keep the risk of infection at a minimum.
What is the lowest temperature Can a human survive?
Below 70 F (21 C), you are said to have profound hypothermia and death can occur, Sawka said.

Plant fall cabbage 6 to 8 weeks before the first frost. Growing plants that have been exposed to cool weather become "hardened" and are tolerant of frost. Cabbage that matures in cool weather is deliciously sweet. Like most vegetables, cabbage needs at least 6 hours of full sun each day; more is better.
Lettuce may cope with light freezing and even one or two hard freezes, but once the thermometer reads 25°F or below, the plants are in danger. That level of cold causes ice to form in the plant tissue, regardless of the amount of moisture in the air.
Frost Tolerance
In general brassicas will tolerate a light frost, when temperatures dip between 28-33ºF for a few hours. Young plants are more vulnerable than mature ones, however, and must be covered to survive a hard frost, when temperatures fall below 28ºF for more than 2-3 hours.
