Can Vitamin D Deficiency Cause Excessive Head Sweating? Other Causes To Note

Excessive head sweating can be caused by a variety of factors, and vitamin D deficiency is one of the potential contributing factors. Head sweating, also known as craniofacial hyperhidrosis, refers to excessive sweating on the scalp, forehead, and face. Sweating is a natural bodily response to regulate body temperature, but excessive sweating in certain areas can be bothersome and may indicate an imbalance in the body's thermoregulatory system. 

Head sweating alone is however not a definitive symptom of vitamin D deficiency, and it could be related to other underlying issues as well. In this article we will look at how vitamin D deficiency affects the body and why it leads to head sweating at all. Dr Tushar Tayal, Consultant, Internal Medicine, CK Birla Hospital, Gurugram, shares insights.

Role Of Vitamin D In Calcium Absorption

“Vitamin D is a fat-soluble vitamin that has long been known to help the body absorb and retain calcium and phosphorus,” says Dr Tayal, adding “The active form of vitamin D 1,25Dihydroxyvitamin D3 (1,25(OH)2D3), which is the hormonally active form of vitamin D, is the major stimulator of active intestinal calcium absorption. If the body is deficient in Vitamin D, even if there is enough calcium in the diet, this calcium will not get absorbed in the blood resulting in calcium deficiency and consequently osteoporosis,”

According to a study published in the New England Journal of Medicine, approximately 100 crore people worldwide are affected by vitamin-D deficiency and around 50% of the global population have vitamin D insufficiency.

"Without adequate vitamin D, the body absorbs no more than 10% to 15% of dietary calcium. In the vitamin D–sufficient state, the intestinal calcium absorption increases to 30% to 40%," says a study published in Current Rheumatology Reports.

• Muscle cramps involving the back and legs 
• Psychological symptoms, such as confusion, memory loss, depression, and anxiety
• Osteoporosis and frequent fractures
• Menstrual cramps

Is Head Sweating A Common Sign Of Vitamin D Deficiency?

While there is no direct link between vitamin D deficiency and head sweating, addressing nutritional deficiencies is essential for overall health and may indirectly help in managing excessive sweating. A diet lacking in vitamins and minerals can lead to excess sweating.

Usually, excessive head sweating occurs due to the following reasons:

Hyperactive sweat glands: Some individuals may have overactive sweat glands, leading to increased sweating in certain areas, including the head.

Hormonal fluctuations: Hormonal changes, such as those occurring during menopause, can contribute to increased head sweating.

Stress and anxiety: Emotional stress and anxiety can trigger excessive sweating, including on the head and face.

Heat and humidity: Hot weather and high humidity levels can lead to increased sweating.

Certain medical conditions: Conditions such as hyperthyroidism, diabetes, and certain infections can cause excessive sweating.

Natural Source Of Vitamin D

Dr Tayal says, “Vitamin D supplements are available in two forms: vitamin D2 (“ergocalciferol” or pre-vitamin D) and vitamin D3 (“cholecalciferol”). “Both are also naturally occurring forms that are  produced in the presence of the sun’s ultraviolet-B (UVB) rays, hence its nickname, “the sunshine vitamin,” but D2 is produced in plants and fungi and D3 in animals, including humans.,” he adds. 

Some natural sources of vitamin D are as follows:

• Salmon and sardines
• Cod liver oil
• Egg yolk
• Shrimp
• Mushrooms
• Milk and butter
• Yoghurt 

Additionally, according to Dr Tayal, sunlight exposure 30 min per day will boost vitamin D production in the body. “The sun’s ultraviolet B (UVB) rays interact with a protein in the skin, converting it into vitamin D3, the active form of vitamin D. The Recommended dietary allowance of vitamin D is 600 IU per day,” he concludes.
