Doctor Anastasia Titova: lack of energy and drowsiness, frequently occurring colds may be explained by a shortage of vitamin D in the organism.
Titova mentioned that vitamin D deficiency is one of the most common health issues at the end of winter. Mainly, the human body acquires it during exposure to sunlight on the skin, and after several cold months without sun, it may experience a serious lack of this vitamin.
The specialist emphasized that an adequate amount of the substance is crucial for the functioning of the immune system, and its low level leads to a weakening of immune resources. According to Titova, regular colds may arise precisely due to a deficiency of vitamin D.
“Vitamin D plays a vital role in regulating the immune response, so regular colds may be a sign of its deficiency. Another symptom is fatigue, drowsiness, impaired concentration and memory,” shared the doctor.
The therapist drew attention to the fact that the functioning of digestion depends in many ways on the “sun” vitamin. If it is lacking, abdominal pain, constipation or diarrhea, as well as appetite disturbances and unwanted weight fluctuations, unexplained nausea may occur.
Other symptoms.
Bone and back pain;
Muscular weakness, muscle pain or muscle cramps;
Mood swings, depression;
Increased irritability, self-control problems;
Difficulty falling asleep, insomnia;
Excessive hair loss.
From October to March, the level of vitamin D in the body may be at its lowest. It is necessary to check its content in the blood through tests and, if necessary, replenish it. A large amount of this vitamin is found in fatty fish (herring, salmon, sardine), egg yolks. In sunny clear weather, it is enough to spend just 15 minutes outside.
