Sweating is part of human nature. It is essential to keep our body from overheating through the cooling system. 

Many reasons cause sweating, such as exercise, hot weather, stressful situation, fever affected time or even spicy food can be a reason.

But in most cases, sweating fulfilling its purpose and our cooling down. That’s it. 

The problem comes into play when there is excessive sweating. It can negatively affect our life. 

Let’s dive deep into why do we sweat so much and try to find out the treatments available for this.

What are the reasons that cause you to sweat so much?

Sweat is produced by sweat glands that are located in our skin. For those who have excessive sweating problems, these glands do not shut off. Sometimes, you will sweat even if you are in an air conditioning situation or just sitting and watching television.

The excessive sweating problem is also called hyperhidrosis.

There are two types of hyperhidrosis.

Primary hyperhidrosis and secondary hyperhidrosis. Let’s discuss both of them deeply.

1- Primary hyperhidrosis

It is hyperhidrosis with no medical reason. This sweating is an abnormal situation. People who are affected have a certain type of gland called the eccrine sweat gland. It is found in your feet, palms, face, and armpits. 

It usually starts from puberty and seems to run in some families, so there is maybe a genetic link.

Even doctors are sure why these people have primary hyperhidrosis. 

Here are some of the treatment methods to cure primary hyperhidrosis mentioned below:-

  • A low-intensity electrical current treatment is called iontophoresis. 
  • Botox injections for underarm sweating. 
  • Over-the-counter or prescription-strength antiperspirants that contain aluminum
  • Medications called anticholinergics that affect the nerve signals to sweat glands. You may take them in pill form or apply them to your skin as a cream or with a medicated wipe.

2- Secondary hyperhidrosis 

It is very different from primary hyperhidrosis. Here, sweating won’t happen whole over the body, instead only hands, underarms, face, or feet are vulnerable to sweating. 

Medical conditions like pregnancy, diabetes, hyperthyroidism, menopause, anxiety, infection, Shingles, and lymphoma can be potential reasons to be a secondary hyperhidrosis patient.

Checking the underlying condition and through proper treatment, it can be cured. It is better to tell your doctor when you are having this problem, it eases you to find the reasons behind this. 

How can I stop sweating so much?

As we discussed earlier, sweating is a natural way of regulating temperature. 

But if you find sweating undesirable in a particular situation, here are four ways to stop sweating.

1- Apply antiperspirant before bed

Antiperspirant will block the sweat from coming out from the skin surface. The sweat is still produced but didn’t reach the surface.

To get the best results out of it, make sure that your underarms are clean and dry before going to bed. Because it takes some time to create a sweat block over ducts.

2- Wear breathable fabrics

The clothes you wear also is important in the amount you sweat. It is better to wear light, breathable fabrics with good ventilation dresses. 

3- Keep cool

Sweating is the way to cool down your body. So if you are cool down the body, it will be more helpful. It is a really good idea to place a bowl of ice in front of a fan to circulate cold air around the room. 

4- Avoid certain foods

Some foods can affect sweating. Spicy food is on the top of the list. Also, caffeine is not a favorable one. It can stimulate our adrenal glands and cause our palms, feet, and underarms to sweat. 

When should I be concerned about sweating?

You need to worry about sweating and should consult a doctor if:-

  • Sweating starts to disrupt your daily routine.
  • Sweating at night without any reason.
  • Start to experience emotional distress.
  • Begin to sweat more than usual.

Does coronavirus make you sweat a lot?

In patients with COVID-19, sweating along with fever is a common symptom. But profuse continuous sweating even when afebrile is seen in some patients admitted with COVID-19.

What cancers cause sweating?

Here are some of the cancers that can be caused to sweat more than usual.

  • non-Hodgkin lymphoma
  • Hodgkin lymphoma
  • carcinoid tumors
  • leukemia
  • mesothelioma
  • bone cancer
  • liver cancer

Why do I always have sweaty armpits?

Excessive sweating occurs without such triggers. People with hyperhidrosis appear to have overactive sweat glands. The uncontrollable sweating can lead to significant discomfort, both physical and emotional. As discussed above, when excessive sweating affects the hands, feet, and armpits, it is called focal hyperhidrosis.

Does shaving armpits reduce sweat?

Because hair holds onto moisture, shaving your armpits may result in less sweating, or at least less noticeable sweating (sweat rings on your shirt sleeves, for example). Shaving may also cut down on the odor associated with sweat. Most hair is porous, meaning it’s able to absorb and hold onto sweat.
