Are you bothered about your excessive sweaty face and head? Know that you are not alone!
Sweating is a natural process that helps to prevent overheating in your body. However, excess of it can cause discomfort and might also be a symptom of an underlying condition.
In this article, we tell you what causes excessive sweating on the face and how you can manage it.
Why Do You Sweat?
Sweating might be a not-so-good experience for you but it is a vital process to control your regular body temperature. The normal temperature of your body is around 90 degrees Fahrenheit. However, the temperature may increase due to outside weather conditions, any kind of physical activity or fever.
If your body is not able to cool that temperature down, there are repercussions. There is a high chance of you suffering a heat stroke or other health issues.
Fortunately, the human body is made with a highly sophisticated mechanism that allows the body temperature to cool down when required. The hypothalamus of your brain sends out signals to the eccrine sweat glands as soon as your body temperature starts rising. That’s when you start sweating and this way the temperature of your body cools down.
Other conditions also tend to make you sweat such as experiencing extreme emotions or eating spicy food. When you are stressed out, excited or terrified about something, your body starts sweating too. But this sweating is partially different from your regular sweat.
That’s because when you are stressed out or scared, your body initiates a fight or flight response irrespective of your temperature. It activates the apocrine sweat glands of your body and you start sweating. 
At times, when you eat spicy food, your mouth feels like it’s on fire. That’s when your brain is tricked to think that your body is overheating and it sends a signal to your sweat glands. Also, during the process of metabolizing food, you experience a light sweat. Same reason, you feel a little restless and sweaty after having a heavy meal.
