because skin temperature may be affected by outside environment but blood temperature does not.

They detect the blood pressure of the internal environment and send the results to the CNS, where it will react in several different ways
Our bodies have nerve cells called thermoreceptors that measure temperature of our internal body and the external environment. When these nerve cells are stimulated by changes inside our bodies and in the world outside, they send their information to the brain, where it is mostly the job of the medulla oblongata to make changes to keep our internal body temperature constant.
Chemoreceptors detect the levels of carbon dioxide in the blood.
Yes, some people are sensitive to changes in weather and may experience headaches or migraines as a result. Rapid changes in temperature, humidity, or barometric pressure can trigger these headaches in susceptible individuals. It is thought that these weather-related headaches are due to changes in the brain's blood vessels or levels of certain chemicals.

Fever evaluation tests, better known as febrile agglutinins tests, are performed to detect the presence of antibodies in the blood that are sensitive to temperature changes.

There is a bedside version of the test in which the doctor collects four or five drops of blood in a small tube, cools the tube in ice water for 30-60 seconds, and looks for clumping of red blood cells.
