There are a few different types of anemia, but the main result of each is the same: A drop in red blood cells. That drop also means your body isn't getting its necessary amount of oxygen, which results in that chilly feeling. “When you're lacking oxygen, you get that cold feeling and fatigue,” says Dr. Morgan.
However, cold intolerance can also indicate an underlying medical condition, such as hypothyroidism, anemia, or peripheral artery disease. Dysfunction of the thyroid gland, arterial blood flow, and low body fat can all cause a person to feel cold.
Since feeling cold all the time can be a sign of a more serious medical condition, it's important not to ignore these symptoms. If you feel cold frequently even when you're in a warm place, or long after you've come in from cold temperatures, check with your doctor to find out what might be going on.
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.
If you or a loved one feel sleepy or fatigued, despite having 7-8 hours of sleep, it could indicate poor sleep quality or be a sign of an underlying sleep disorder. If you have questions or concerns about your sleep health, please speak with your primary care provider.
Cold hands and feet
A vitamin B-12 deficiency can lead to the feeling of cold hands and feet, numbness, or tingling. Unfortunately, up to 15% of the general population is deficient in this important vitamin. To boost your intake of vitamin B12, consume more meat, poultry, eggs, milk, and other dairy products.
A slower metabolism causes women to produce less heat so they tend to feel colder. “It's simple physics,” says Boris Kingma, PhD, a thermophysiologist, at The Netherlands Institute for Applied Science (TNO). “If you lose more heat than your body produces, your body temperature will go down and you will sense that.”
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.
But don't worry, this is completely normal. When it's cold our intelligent bodies make the blood vessels in our feet and hands constrict (aka. spasm) to prevent heat escaping from our core. Having naturally colder hands and feet is quite common, and it doesn't necessarily mean that an underlying disease is causing it.
Common underlying issues that can make you feel tired after waking up and persist throughout your day include sleep inertia, sleep disorders, bright light exposure, and a poor bedroom environment, to name a few.
Hypersomnia means excessive sleepiness. There are many different causes, the most common in our society being inadequate sleep. This may be due to shiftwork, family demands (such as a new baby), study or social life. Other causes include sleep disorders, medication, and medical and psychiatric illnesses.
Low magnesium contributes to muscle cramp and tension which, in turn, causes the diameter of the arteries (which deliver oxygen-rich blood from the heart to body tissues) to reduce in size. With less room to manoeuvre, blood circulation becomes sluggish and, therefore, contributes to cold hands and feet.
A magnesium deficiency can cause your muscles to tense up which, in turn, causes the diameter of your arteries to decrease, thus decreasing blood flow, resulting in cold hands and feet. Increasing your magnesium intake can help the blood vessels dilate, allowing blood to flow to the fingers and toes.
If you aren't feeling rested when you wake up, despite getting to sleep at least 8 hours prior, then it might not be the quantity of your sleep that's the problem. It could be your sleep quality that needs some attention. The amount of sleep you get is important, but equally important is the quality of that sleep.
Everyone needs a certain number of sleep hours, and if you don't get what you need, you may find it difficult to hop out of bed feeling refreshed. Finally, sleep disorders could be the cause. Various sleep disorders can reduce the quality of your sleep and make it so your night isn't restful.
Symptoms of low blood pressure
lightheadedness or dizziness. feeling sick. blurred vision. generally feeling weak.
Blood pressure generally is higher in the winter and lower in the summer. That's because low temperatures cause blood vessels to temporarily narrow. This increases blood pressure because more pressure is needed to force blood through narrowed veins and arteries.
Symptoms when vitamin D is low
Most people with vitamin D deficiency are asymptomatic. However, if you're exhausted, your bones hurt, you have muscle weakness or mood changes, that's an indication that something may be abnormal with your body.
2. Feeling cold. Cold hands and feet can be a result of iron deficiency anemia. People with anemia have poor blood circulation throughout their bodies because they don't have enough red blood cells to provide oxygen to their tissue.
