July is here and the temperatures are falling. The good news is that you can assist your body to acclimatize to the cold faster.
Research has found that a person on exposure to the cold can get acclimatized and stop shivering after two weeks implying that you can get used to cool environments. This shows that humans seem to have some innate ability to acclimatize to the cold.
On initial exposure to cold, the body does a lot of shivering. A human body’s initial response to cold stimuli is the heart rate and metabolisms speeding up generating heat. Similarly, the blood vessels narrow and draw away from the surface of the skin making the skin temperature to drop further. The vascular system responds by pulling blood towards the warmer interiors to escape the external cold.
After a reasonable exposure period, the shivering more or less stops. At this time the heart rate and metabolism still increase in response to the cold-water bath but the blood vessels no longer constrict and the skin temperature stops dropping like there before. You now experience less discomfort during their cold baths as the body has now gotten used to the cold.
This acclimatization to cold is associated with some body’s internal adjustment mechanism due to a specific kind of fatty tissue, known as “brown fat” that assists the body to generate heat in response to consistently cold conditions. Persistent exposure to cold exposure somehow causes initiates brown fat. It's known that newborns have a lot of brown fat that assists them to stay warm considering that they don’t have enough muscle to shiver. As people grow up there are some parts of their body mainly the area at the neck and upper region of the spine which either retains brown fat or produce new brown-fat tissues to counteract the cold.
Where this brown fat is important since the monitored by the brain detects the cold by sensing the temperature of blood passing into it through the neck. This is the reason why someone feels warm by wrapping a scarf around the neck. The scarf warms the neck and the blood passing through which causes the brain to think it’s warm. This exposure to low temperatures activates brown-fat formation making us feel more comfortable at colder temperatures.
It is normal for people to use other methods to reduce stress caused by cold temperatures such as taking hot fluids and room heating which in essence do not make the body more resistant to cold. These measures reduce the body’s ability to adjust to colder temps, but training your body to adapt to the cold can feel more comfortable during the cold season without needing to entirely rely on an external heating system. When you spend more time exposed to the cold outside or anything that causes shivering a few times a day will make you begin to feel more comfortable in colder temps in a relatively short time.
The quickest way to get used to the cold
Cold showers are not everybody’s cup of tea but they make the body adapt very quickly. You can start with a cold shower for a relatively short time and then increase the duration every day by 10 seconds. Taking time in a cold shower or other cold places is ok for most though those with heart problems need to take care. Exposure to cold makes your blood vessels constrict and blood pressure goes up and this may be problematic for people with a heart condition. When you are healthy and want to improve your body’s natural ability to adjust to the cold, a week of shivering and a few cold showers s
