“When you're lacking oxygen, you get that cold feeling and fatigue,” says Dr. Morgan. Other symptoms of anemia that she notes include: Paleness.
Anemia happens when you don't have enough healthy red blood cells to bring your body all the oxygen it needs. It will leave you tired, weak, dizzy, and short of breath. It can also make you cold, especially your hands and feet.
Anemia occurs when a person does not have enough red blood cells circulating and carrying oxygen throughout the body. Symptoms of anemia , including feeling cold, result from a relative lack of oxygen. Other symptoms can include: weakness or fatigue.
If you are relatively fit and seem to "run hot," there's an explanation for that: Muscle tissue generates heat, offering a different protection from the cold. If you're relatively petite, not only does a low BMI heighten your response to cold, but so does your overall surface area.
New research suggests regular exposure to the cold could deliver an avalanche of surprising health benefits, helping you to torch more flab, fire up your metabolism, reduce your risk of diabetes, strengthen your heart and lungs, train harder and even fight off depression.
Summary: New study suggests that people with more muscle mass are less susceptible to heat loss and heat up faster after cold exposure than non-muscular individuals.
But a University of Utah study published in the journal Lancet found that women's core body temperatures can actually run 0.4 degrees F higher than men's on average. And women's hands can be significantly colder — 82.7 degrees F on average, compared with 90 degrees F for men.
Often, this is our body's response to being cold. But you might not know that chills can also be a symptom of anxiety. Physiological reactions to anxiety can cause your blood to flow less efficiently and, therefore, leave you with chills. If you have chills from anxiety, you can begin to feel shaky and start to shiver.
If you just can't warm up, it could be a sign that you need to drink more water. "Up to 60% of the adult human body is water, and water helps regulate body temperature," Moon said. "If you're adequately hydrated, water will trap heat and release it slowly, keeping your body temperature in a comfortable zone.
Poor blood flow (circulation) in your legs and feet causes cold feet. Poor blood flow means that it takes longer for the blood to reach your feet. Your blood travels through pathways (blood vessels) in your circulatory system. These pathways can close, harden and narrow, making it difficult for blood to flow steadily.
Weakness is a lack of physical or muscle strength. You feel like you need to use extra effort to move your arms, legs, or other muscles. General weakness often occurs after you've done too much activity at one time. For instance, maybe you took an extra-long hike.
Symptoms of body weakness
It is possible to predict whether the body is weak or not based on the following symptoms: Fatigue, exhaustion, or night sweats, pale skin, sometimes fainting. Weakness lasts more than 6 months. Sore throat, muscle pain, joint pain but no redness.
Even at rest, your muscles produce around 25% of your body's normal temperature, so more muscle mass means a greater heat production.
Muscle mass: Muscle mass produces more heat than fat. So even if two people have the same body weight, their sweat rate will differ based on their percentage of muscle mass. Health status: A number of health conditions and life stages can impact how much you sweat.

That is because summer's warm temperatures make you feel more tired. On the other hand, cold weather helps you feel better. When it is cold, your body has to work harder, which leads to increased endorphin production. More endorphins in your body give you a happier state of mind while at the same time relieving stress.
The numerous potential causes for coldness include hypothyroidism, calorie reduction and general aging, where people become more sensitive to cold temps due to a decrease in the metabolic rate and thinning of fat under the skin.
''In fact, it might tend to be thicker in summer, when the body loses water through sweating, and people need to drink more to remain hydrated,'' she said. Temperature is not the chief regulator of the thickness of blood, she said.
Hypothyroidism
“This is one of the most common reasons people always feel cold,” Abokede said. “The thyroid drives metabolism. With a low-functioning thyroid gland, metabolism is slowed and the body can't generate an adequate amount of heat to maintain core body temperature.”
Can low vitamin D cause you to feel cold? Instead, vitamin D deficiencies typically result in rickets and other bone deficiencies. [10] While these conditions can lead to feelings of coldness, they don't seem to play as direct a role in thermoregulation as the B vitamins.
If your blood pressure drops too low, your body's vital organs do not get enough oxygen and nutrients. When this happens, low blood pressure can lead to shock, which requires immediate medical attention. Signs of shock include cold and sweaty skin, rapid breathing, a blue skin tone, or a weak and rapid pulse.
