Why does dermatitis itch especially at night

Many people with dermatitis symptoms will feel abnormal itching at night, which will affect their sleep quality and duration, and will also make people feel very painful. You can regulate your body through diet, such as eating more fresh vegetables. Many vegetables are rich in vitamins, and these nutrients can promote skin metabolism.

Vegetables are rich in nutrients such as vitamins, inorganic salts, and cellulose. Eating fresh vegetables regularly is good for your health, but some people may develop dermatitis after eating certain vegetables.

Because some vegetables can decompose a photosensitive substance in the human body, and some people are very sensitive to this photosensitive substance. When eating or touching certain vegetables, such as amaranth, rapeseed, purslane, tomatoes, eggplants, potatoes, cauliflower, etc., when the photosensitive substances in the body reach a certain concentration, the skin of exposed parts of the human body (face, hands, feet) is exposed to direct sunlight, which can cause metabolic disorders and cause dermatitis.

This type of dermatitis is medically known as "vegetable photodermatitis". The main symptoms are itching and burning sensation on the local skin, and acute edema, ecchymosis or blisters may be seen, as well as stinging pain. In severe cases, the lips, eyelids and face may swell and turn purple-red. It may also be accompanied by systemic reactions such as headache, fatigue, fever, nausea, vomiting, and loss of appetite.

1. Avoid scratching

Scratching can cause the skin to be constantly exposed to mechanical stimulation, causing it to thicken and even cause infection. Scratching also has a reinforcing effect. The more the patient scratches, the more itchy it becomes, and the more itchy it becomes, the more he scratches, forming a vicious cycle and prolonging the course of the disease.

2. Avoid washing with hot water

In the acute stage of dermatitis and eczema, due to the dilation of capillaries in the skin, there will be varying degrees of skin redness, swelling, papules, and blisters. Washing or soaking with hot water will increase the redness and swelling, increase the amount of exudate, and worsen the condition. Therefore, patients with dermatitis and eczema should take a warm shower and avoid soaking in hot water or rubbing hard.

3. Avoid washing with soap

In particular, soaps with high alkalinity are chemical irritants to the skin and can aggravate dermatitis and eczema. If you need to use soap to remove stains, it is best to choose boric acid soap with less irritation.

4. Avoid irritating foods

Stimulating foods such as chili peppers, alcohol, strong tea, coffee, etc. can aggravate itching and easily cause eczema to worsen or relapse, so they should be avoided.

5. Avoid blind medication

Dermatitis and eczema have a long course and are prone to recurrence. Patients must cooperate with doctors and receive treatment patiently. Some people are eager to receive treatment, but they do not pay attention to the harm caused by untimely treatment and the drawbacks caused by the abuse of drugs: Seborrheic dermatitis is caused by bacterial infection. If it is not treated for a long time, the sebum will erode the hair follicles, which can easily breed bacterial infection, causing the hair follicles to be destroyed and the hair to stop growing, gradually causing symptoms of hair loss.
