The human body has a system of regulating body temperature, which involves the nervous system, the hormonal system, and collaboration with other systems, to adjust to the surrounding environment, both the weather (ambient temperature), the presence of danger threats, and others.
At night where the ambient temperature is generally cooler, the body always has to keep the body from releasing too much heat, so that vital organs are not disturbed. This condition is achieved by shrinking the blood vessels or blood supply in parts of the body that lack oxygen, such as the ends of the body, namely the tips of the fingers, toes, tips of the ears, etc. In this way, the body can reduce body heat lost to the surrounding air. This response can be analogous to those of trees that shed their leaves in winter to reduce liquid evaporation.
In conditions where the blood vessels at the ends of the body shrink, it will feel colder, because in the human body that carries hot temperatures are blood vessels. This is a normal and normal thing to happen, especially at cold room temperatures, or at certain times such as shock, anxiety, fear, and others.
On the other hand, there are also several diseases that can cause similar symptoms, but are generally not related to these conditions (cold, shock, fear), for example in blocked arteries, nerve injury, or in damage to blood vessels (vasculopathy). If you have doubts, consult a general practitioner or neurologist, so that a more complete examination and treatment that suits your condition.
Thus, hopefully it can be useful.
