What’s amazing about the human body is its ability to counteract natural conditions that occur around you, such as the blistering cold temperatures we’ve been experiencing recently in North Texas.
But what role does the blood play in all of this? And how does it help you?
Well, for starters, when the temperature drops and your body begins to get cold, your blood vessels constrict and your blood is rushed to the interior of your body, namely towards the heart and brain. This is vital because it adds to the insulating power of the skin and there’s less heat lost from blood circulating near the surface. This explains why your toes and feet are the first to get cold!
The cold weather also affects your blood pressure. This ties into the fact that your blood vessels constrict, meaning your body has to work harder to get the blood where it needs to go, thus increasing the pressure.
In general, your blood pressure is higher in the winter than in the summer.
Abrupt changes in temperature can be dangerous, so if you need to go outside when it’s really cold, you must be bundled up to allow your body to ease into the new temperature.
The body is amazing and will subconsciously do its part to keep you safe, just make sure you make smart decisions and do your part, too!
