Introduction
In general, excessive sweating can lead to bodily dehydration, which may result in symptoms such as dry mouth, dizziness, palpitations, and chest tightness. Dehydration reduces water content in the body, leading to decreased oral mucosal moisture and saliva secretion, thereby causing dryness and discomfort in the mouth. Additionally, dehydration decreases blood volume and increases blood viscosity, impairing circulation and resulting in dizziness and lightheadedness.
Generally, excessive sweating can lead to dehydration, which may cause symptoms such as dry mouth, dizziness, palpitations, and chest tightness. A detailed analysis is as follows:
1. Dry Mouth
Insufficient body fluids reduce the secretion of oral mucosal membranes and saliva, leading to a dry and parched sensation in the mouth.
2. Dizziness
Dehydration reduces blood volume and increases blood viscosity, impairing circulation and resulting in dizziness and lightheadedness.
3. Palpitations and Chest Tightness
Reduced blood volume due to dehydration forces the heart to work harder to maintain normal circulation, potentially causing palpitations and chest discomfort.
In addition to the above symptoms, severe dehydration may also manifest as dry skin, decreased urine output, and dark yellow urine. If these symptoms occur, it is important to replenish fluids promptly to prevent worsening dehydration. In hot environments or during intense physical activity, fluid intake should be increased appropriately to maintain the body's fluid balance.
