The feeling of constant cold can hide health problems such as diabetes, hypothyroidism, anemia or poor circulation.

Be cold when the thermometer reads -5 ° outside, this is normal. To be shivering all the time, even in the summer when the person next to you is swimming, should put us in the ear. The thermoregulation of men and women does not work the same way, but excessive cold can hide a real health problem. The American site Health has listed the main causes of these chills:

Too skinny
A low body mass index may be one of the reasons that cause a drop in the temperature of the body. When we are too thin, we lack the fat to isolate the body from the cold, and the fact of not bringing enough nutrients to the  body deprives some of the energy needs to warm up.

Thyroid in bulk
Always having cold can be one of the symptoms of hypothyroidism, the drop in thyroid hormone levels. The metabolism slows down and prevents the body from producing enough heat. If you also feel tired, if your skin is dry and your hair becomes abnormally thin, consult a doctor.

Not enough iron
Low iron levels in the blood can also cause heat loss. This mineral trace element is used to transport the oxygen cells in the blood, and thus promote good general thermoregulation. Without iron, you will not only feel very tired, but you may also be very cold.

Poor circulation
If your feet and hands are still frozen, your problem is probably in traffic. Your heart is struggling to pump enough blood to irrigate the body to the ends where some of your arteries are clogged. Results: your fingers and toes tend to turn blue. Consult a specialist to determine the exact cause of this disorder and to prescribe the necessary treatment.

Tiredness
Lack of sleep can break your nervous system and wreak havoc on the brain’s mechanisms that regulate body temperature. To stop spending your evenings shaking, try going to bed early or taking a nap in the afternoon.

The dehydration
The human body consists of a large majority of water, and this water helps to regulate our internal temperature. Drinking regularly helps the body stay warm and better withstand temperature changes.

Diabetes
People who have diabetes and struggle to monitor their condition may develop peripheral neuropathy, says Health. This form of nerve damage is manifested by numbness, tingling, pain, and sometimes cold sensation in the feet and hands. Consult a doctor to receive the most appropriate treatment.
