Heavy sweating: mineral deficiency in summer

Should you take magnesium and more during hot weather? 

For many, it's annoying – but sweating is a vital process: especially in summer, during hot weather, the body must regulate its temperature intensely to avoid overheating. This is done through sweat – essentially our built-in air conditioning system. Sweat evaporates on the skin, releasing heat in the process. However, important minerals are also lost this way. 

Find out which micronutrients are especially important now and how to optimally support your body on hot days.

Sodium: Especially important for athletes in summer 

The most abundant mineral in sweat is sodium. A sodium deficiency from normal sweating is rarely a concern in the long term, since we usually get enough sodium through dietary salt. In fact, most people consume too much sodium, as salt intake typically exceeds recommended levels. 

However, sodium is particularly important during exercise: it is one of the key electrolytes and is essential for fluid distribution in the body. Especially when exercising in hot weather, heavy sweating can lead to a temporary sodium deficiency. Symptoms may include dizziness, headaches, and fatigue.

Mineral-rich diet during hot weather 

In addition to sodium, sweat also contains small amounts of calcium, magnesium, potassium, iron, zinc, selenium, and copper. In the short term, mineral losses are not a problem for healthy individuals. However, depending on one’s diet, it can be more difficult to meet the requirements for some minerals. As a result, mineral stores can quickly become depleted due to heavy sweating during prolonged heat. 

For example, vegans need to pay special attention to their calcium intake, as they do not consume calcium from dairy products. Women are generally at a higher risk of iron deficiency due to menstruation. While zinc is abundant in grains, these also contain a substance that inhibits zinc absorption in the gut (phytic acid). Frequent stress can further increase magnesium requirements during the summer. 

That’s why a healthy and varied diet is especially important when sweating heavily. If you choose to take a dietary supplement in summer, the best option is a product that meets your mineral requirements. Ideally, consult a micronutrient therapist for guidance.

What are the symptoms of magnesium and mineral deficiencies? 

Since minerals have various functions, a deficiency can manifest in different ways. A magnesium deficiency caused by sweating may lead to the following symptoms: muscle and calf cramps, heavy legs, headaches and dizziness, or even fatigue – as magnesium is essential for energy metabolism. 

Potassium regulates the heartbeat, while iron and copper are responsible for oxygen transport in the blood. The main symptom of an iron deficiency is anemia, whereas a selenium or zinc deficiency may lead to frequent infections – even in summer! Studies have particularly examined the effects of heavy sweating in athletes: a lack of fluids and minerals had a negative impact on performance.

Hyperhidrosis – Nutrition Matters Too! 

Excessive sweating can also be pathological. This condition is known as hyperhidrosis. Some people sweat heavily over their entire body, or only in certain areas such as the armpits, hands, feet, or head. People affected by hyperhidrosis should therefore also pay close attention to their intake of magnesium and other nutrients – and not just in summer! Especially individuals who sweat a lot on a regular basis have an increased need for magnesium and may develop a deficiency over time.

Conclusion: Magnesium and more when sweating excessively! 

Prolonged heat waves as well as excessive pathological sweating can increase the need for minerals. During these times, it is especially important to maintain a balanced diet or, if necessary, supplement with a high-quality mineral complex. The most important minerals when sweating heavily are: 

• Magnesium and calcium, 
• Iron and copper, 
• Potassium, 
• Zinc and selenium 
• and sodium for athletes.
