What are the "little blisters" that grow on your hands in the summer? Knowing them clearly can help you avoid them

As summer approaches, many people will develop some transparent "little blisters" on their fingers. After gently pricking them, some clear water will flow out. If you are not careful, the pricking will cause itching and discomfort in this area.

You should be careful at this time, you may have "dyshidrotic eczema"!

What is "dyshidrosis"?

Dyshidrosis is a recurrent skin disease that occurs on the palms, soles, or sides of fingers and toes, often accompanied by excessive sweating of the hands and feet.

In addition, it may also manifest as:

Millet-sized blisters occur in groups and are symmetrical on both sides.

The blisters contain clear fluid.

There may be itching or burning.

The blisters will usually dry up and peel off after 2 to 3 weeks, revealing thin and tender skin, which may be painful.

Dyshidrotic eczema will recur, and sometimes new blisters will appear before the old ones have healed.

It is currently believed that this disease is an eczema-like reaction of the palm and plantar skin caused by various factors.

It is not "athlete's foot" and is not contagious.

The disease usually begins in late spring and early summer, is most severe in summer, becomes milder when the weather turns cooler, and is less common in winter.

What should I do if I get sweat herpes?

Up to now, the cause of dyshidrotic eczema has not been fully understood, so there is no way to "cure" dyshidrotic eczema.

Normally, many people like to pop dyshidrotic eczema, but this is a completely wrong example.

Because our hands and the tools we use are not necessarily clean, when the blisters are punctured, the damaged surface increases the chance of infection, and the infection will in turn aggravate the condition.

Therefore, instead of "harming" it, we need to "protect" it.

Can dyshidrotic eczema be “washed off”?

Some people believe that dyshidrotic eczema is caused by dirty skin or contact with something, so they try desperately to "wash it off".

In fact, washing hands frequently cannot fundamentally solve the problem. Excessive bathing will increase the irritation factor and may even induce more serious illness.

Therefore, people with dyshidrotic eczema should not only avoid washing their hands excessively, but should also try to avoid irritating detergents and soaps, including dishwashing detergents, shower gels, etc.

Medication is a good way to deal with "dyshidrosis":

1. When itching occurs, you can apply compound calamine lotion, which has a better antipruritic effect on dermatitis and eczema.

2. During shedding, you can apply some hormone ointment under the guidance of a doctor.

The side effects of using these ointments in short terms and in small doses are not serious and will not cause harm to the body, so there is no need to worry too much.

At the same time, you should keep the shedding area moisturized and apply some moisturizing and anti-inflammatory protective ointments, such as urea cream, vitamin E lotion, etc.

3. If the itching is unbearable and peeling is severe, seek medical attention promptly and take some antihistamines orally.

These preventive measures should be remembered

01 Form a good lifestyle

Maintain an optimistic and stable mood and get 6 to 8 hours of sleep every day.

02 Eat more fresh vegetables

In normal times, pay attention to supplementing vitamins and trace elements.

In addition, you should pay attention to a lighter diet. Fatty, sweet, greasy, or spicy and irritating foods will damage the spleen and stomach functions, thereby causing water metabolism disorders in the human body and causing recurrent diseases.

03 Prevent skin aging

Especially in summer, avoid strong sunlight and wear sunscreen when going out.

04 Hand care

When the seasons change, keep your hands away from water and detergents as much as possible, and use hand cream more often to keep them moisturized.

05 Avoid irritating contact

Find out whether your sweat herpes is related to metal. If so, try to avoid it. This method is highly effective for patients with combined metal allergies.

06 Acupoint massage

Massage the Laogong point, press the tip of your left thumb against the Laogong point on the palm of your right hand, press vertically downward, and use the rest of your fingers to press on the back of your hand, with pressure increasing from light to heavy, pressing and releasing for 1 to 2 minutes.

In addition, massaging the Hegu and Yuji points can clear away heat and dampness, promote blood circulation, protect the skin, and relieve itching.
