How can young girls take care of their bodies?

1. Don't wear heavy makeup

Heavy makeup can seriously block the breathing state of women's skin pores, and girls wearing heavy makeup during puberty can be extremely harmful to the skin. And the chemicals in cosmetics can also seriously harm developing skin. This not only affects body temperature regulation, but also easily causes "cosmetic macules", which affects facial muscle development and bodybuilding.

2. Eat a handful of nuts every day

Nuts help the body grow, because nuts contain linolenic acid and linoleic acid that help growth and development, walnuts, almonds, melon seeds, sesame seeds and other nuts contain a lot of unsaturated fatty acids, and the phospholipid content is also quite rich, so eating a handful of nuts a day is very helpful for the growth and development of adolescent girls.

3. Start wearing a bra

Some girls have breasts that increase rapidly during puberty, and if you don't wear a bra for a long time during this period, it will cause sagging breasts over time. The sagging of the breasts will affect the blood circulation of the breasts, which is extremely harmful to the breasts. Cause part of the blood stasis and cause breast diseases; Strenuous exercise can also cause mastitis due to trauma to the breast.

4. Vitamin supplementation

Vitamin A can maintain the normal growth and development of the body and make people bright. Vitamin D insufficiency can lead to mild rickets or osteoporosis. Vitamin C deficiency makes it easy to bleed. Vitamin B1 smooths the skin. These vitamins are mostly found in animal liver, eggs, cod liver oil, spinach, carrots, peppers and other foods, while fresh vegetables and fruits contain more vitamin C.

5. Avoid wearing tight pants

Leggings can affect women's blood flow and lymphatic blockage, especially during the rapid growth and development of adolescent women, and are an invisible damage to the vagina and uterus of young girls.

Leggings will hinder joint extension and flexion and normal body development, and it is very easy to cause vulvitis in young girls, vulvar itching, pain, redness and swelling, because scratching can make the epidermis diffuse ulcers, more painful and itchy after urination, and inguinal lymph nodes are swollen and painful due to infection.

6. Don't use breast enhancement products

After puberty, teenage girls become more aware of the importance of breasts to a woman's overall beauty. During this period, girls with small breasts will try to use it when they see breast enhancement advertisements. Most breast enhancement products contain a lot of estrogen, although it has a temporary effect, but over time, it will increase the possibility of cancer in the breast, vagina, cervix, uterine body, and ovaries.

Abuse of estrogen not only causes nausea, vomiting, and anorexia, but also leads to uterine bleeding, uterine hypertrophy, menstrual disorders, and liver and kidney damage.

7. Don't pull out your eyebrows

The beauty of adolescent girls is not fully developed, and the eyebrows themselves have the effect of low-grade sweat and dust, and at the same time play a role in protecting the eyes. At this time, the damage caused by eyebrow pulling to the base of the eyebrows cannot be repaired in the future. At this time, eyebrow pulling and eyebrow drawing are equivalent to removing the eye barrier, so that dust and bacteria fall straight into the eye socket without hindrance, and it is easy to suffer from eye disease.

Pulling out the eyebrows is a vicious irritation to the nerve endings around the orbit, which can cause the imbalance of eye muscle movement, resulting in sagging skin around the orbit, easy to wrinkles and droopy eyelids, and even more affecting beauty in adulthood.
