Why does my whole body itch when I sleep?

Human skin care is very important. There are many reasons for itching all over the body when sleeping, such as allergies. The reasons for itching allergies may be caused by bedding, shower gel, pajamas, diet, etc. If you are allergic, you need to go to the hospital to test the allergens and isolate them, and use anti-allergic drugs for treatment. In addition to allergies, itchy skin may also be caused by dry skin. Due to the dry weather, people's skin will also become tight and dry, which will cause skin itching. At this time, you should pay attention to skin moisturizing. You can use some moisturizing skin care products to improve it. Supplementing more vitamins is beneficial to skin moisturizing. In addition to these causes of skin itching, it may also be caused by other skin diseases, which requires going to the hospital for further examination in time. Pay attention to keep the skin pores unobstructed and clean the skin on time every day. Let us make a detailed analysis of why the body itches when sleeping.

1. Causes of itchy skin

As the temperature drops, the human body partially closes the capillary bed of the skin in order to reduce heat dissipation, the blood flow to the skin decreases, the secretion of sweat and sebum also decreases, the humidity of the skin decreases, and the skin becomes dry, which is more likely to cause itching of the skin.

2. In addition, for a large number of young people, especially white-collar workers and young children, daily bathing has become a compulsory course for them, and they even have to bathe 2 to 3 times a day. The result is that the sebum, which is originally secreted in small amounts, is washed away, making the skin drier and more prone to itching.

2. Stay away from skin itching

1. When the cold wind blows, the itchy skin under the thick winter clothes feels like a bug is crawling on it, making people want to scratch it. Therefore, the sight of many handsome men and beautiful women in well-dressed clothes scratching their itch through their clothes looks quite funny and embarrassing. Nowadays, bathing conditions have improved, and more and more people suffer from itchy skin in winter. Skin itching used to be a common problem for the elderly, but now it has become a common "enemy" for urban white-collar workers.

2. Step 1. The water temperature should be between 30 and 40 degrees Celsius, slightly higher than body temperature but not hot. Water that is too hot will damage the sebum film, cause micro-damage to the skin, and aggravate itching.

3. Take a bath every day, 5-10 minutes each time, no more than 30 minutes. A tub bath or a wooden barrel bath is recommended because soaking in water can promote the skin to absorb moisture, speed up blood circulation, and improve skin metabolism. When taking a bath, do not rub to avoid skin damage and aggravating itching. In addition, when the elderly take a bath, the water level should not exceed the heart level. You can boil two handfuls of starch or oats, put them in the bathtub, and do not rinse them after bathing. Starch baths and oatmeal baths can soothe the skin, reduce skin sensitivity, protect the sebum film, and relieve skin itching.

4. Try to choose neutral or weakly acidic shower gel, and do not use alkaline soap. To judge the acidity and alkalinity, just look at the product description. When taking a bath in winter, you don’t need to use shower gel unless you are particularly dirty.

5. After bathing, be sure to apply lotion before your skin is completely dry. Apply it all over your body except your armpits and groin. The calves, waist, buttocks and forearms have the least sebaceous glands and are most prone to itching, so apply more or repeatedly. Since after-bath lotion only moisturizes for one or two days, remember to apply it even if you don't shower.

3. Notes

Skin itching in pregnant women. Healthy pregnant women may experience systemic skin itching in the middle and late stages of pregnancy, mostly due to bile stasis in the body, which is clinically called intrahepatic cholestasis of pregnancy. In addition, pregnant women often experience itchy abdominal skin in the late stages of pregnancy. This is due to stretch marks caused by excessive stretching of the abdominal wall and stimulation of the sensory nerve endings of the abdominal wall. It is not caused by cholestasis. The symptoms are often mild and do not require treatment.
