Winter: Hibernation or adaptation
Send a link to a friend
[January 30, 2023]
I
once heard a succinct description of natural process as “everything
points towards winter”. As a Midwesterner not so fond of cold, my
immediate response to this synopsis was denial but with time, I’ve
come to adore this mentality. Annual plants know they have one
growing season to complete their life cycle, racing to reproduce
before the frost arrives. The leaves of perennial plants produce the
carbohydrates that are stored in root systems to be utilized the
following spring. And animals have developed a variety of strategies
for surviving winter: hibernation, migration, or adaptation.
Although we live in more elaborate houses and have developed
technologies that allow us to maintain a more moderate interior
climate, winter still impacts our health and well-being. If
migration is not an option, navigating the cold Midwestern winters
can be done so health and happiness don’t suffer.
Hibernation
Technically, it is not possible for humans to hibernate. Hibernation
is a reduction in an animal’s metabolism for the conservation of
energy. Endotherms are animals that can regulate their body
temperature with internally produced heat. This energy production
requires calories and for many animals, winter can be a challenging
time to find food. Animals that can lower metabolism and reduce body
function also reduce calorie requirements. Hibernating animals rely
on body fat reserves or stock-piled food, both of which were
acquired in preparation for winter.

Although not technically hibernating, Scandinavian
cultures practice a philosophy known as “hygge”, an attitude of
enjoying the slower, quieter pleasures of life. Getting cozy during
winter months can provide a contrast to the busyness of the warmer
months. During these periods of rest, time can be used to build back
motivation, reflect on seasons past, and plan for future endeavors.
Activities reflective of the hygge practice include reading a book
in front of a fire, baking a recipe from scratch, playing board
games with friends, sipping hot cocoa or coffee snuggled under cozy
blankets, or writing a letter to a friend.

Adaptation
It is unrealistic to think Midwesterners will spend all winter
indoors, in fact, it isn’t good for our health. Like other
species, habits and strategies have been developed to help cope
with winter. As day length
decreases and outdoor exposure is reduced, mental health can be
negatively affected. According to the American Psychological
Association, seasonal affective disorder (SAD) is a type of
depression typically associated with winter months. To combat
seasonal mood shifts, spending time outdoors is recommended. Taking
a woodland walk, building a snowman, snowshoeing, shoveling snow or
bird watching in a park can contribute to an improved winter
mentality.

Being outdoors in winter provides access to a variety
of physical benefits. Vitamin D is essential in maintaining bone
health and is obtained through exposure to the sun. Exercising in
cold temperatures can result in more calories burned as the body
increases basal metabolic rates to maintain core temperatures. And
maintaining an active lifestyle throughout the winter will help
reduce injury and fatigue once the seasons’ change and spring
activities resume.
Going outside in the winter months requires preparation and
precaution. Checking the weather forecast and wearing appropriate
clothes results in a safer, more enjoyable experience in winter
weather. The Centers for Disease Control and Prevention recommends
dressing in layers, staying dry, and being prepared to seek shelter
if shivering becomes constant.
Good Growing Fact: Tending houseplants in winter months can
provide psychological and physical benefits such as increased
feelings of wellness, a reduction in stress, a feeling of a sense of
purpose, and improved air quality.
