Save the 4 major health crises in summer

Summer seems to be a combination of angels and demons, allowing you to show off your beauty while hiding many health crises - the inevitable sunlight, plenty of air-conditioning in the office, delicious but stomach-damaging cold food - these seemingly ordinary factors are constantly threatening your health. If you are not careful, you will lose everything. Little do we know that without health, how can we be beautiful? Let you be healthy and happy in this summer!

Crisis 1: Gastrointestinal diseases after pleasure

Danger Index: ★★★★

Reason: Eating some cold drinks in the hot summer will naturally make you feel refreshed, and the delicious Haagen-Dazs makes the "ice cream" beauties unable to stop. However, in summer, due to the hot climate, the skin blood vessels expand due to the need to dissipate heat, and the gastrointestinal blood flow will be relatively reduced. After eating a lot of cold drinks, the gastrointestinal blood vessels will contract sharply due to cold stimulation, and the blood flow will be further reduced, causing gastrointestinal dysfunction and even symptoms such as abdominal pain and diarrhea. Various cold drinks, such as soda, beer, etc., contain carbon dioxide. If consumed in large quantities, they will inevitably increase the irritation to the gastrointestinal tract. The production of a large amount of gas can increase the pressure in the gastrointestinal tract, which can easily induce or aggravate existing diseases, such as gastrointestinal inflammation and duodenal ulcers, and in severe cases can cause ulcer perforation.

Precautions

Understand your own physical condition: If you have a weak constitution, or suffer from acute or chronic gastroenteritis, try not to eat cold drinks, because ice cream, ice bricks and other cold drinks contain a lot of nutrients such as fat, cholesterol, protein, sugar and starch. Eating cold drinks will not only affect your normal appetite, but also increase pain and aggravate diarrhea.

Do not drink cold drinks after strenuous exercise: If you eat a lot of cold drinks and cold food after exercise, the strong cold stimulation will cause the gastrointestinal blood vessels to contract, reduce glandular secretion, lead to a sharp decrease in appetite and indigestion, and the sudden cold stimulation can cause gastrointestinal spasm, and even induce abdominal pain and diarrhea.

Eat less cold drinks before and after meals: Eating cold drinks and cold food before and after meals will stimulate the contraction of blood vessels in the gastrointestinal tract, reduce blood flow, cause the digestive glands to secrete less fluid, reduce digestive function, weaken the absorption of nutrients, and cause a decrease in appetite.

Avoid alternating hot and cold:

Alternating between cold and hot food can cause strong irritation to the teeth and gastrointestinal tract, so cold and hot drinks should be consumed separately, with at least 30 minutes between them. Control the amount you consume: If you really can’t resist the urge to have some cold drinks, be careful about the amount you consume. Eating too much at one time will dilute the gastric juice and affect digestion. Cold food will stimulate the intestines, causing hypermotility, shortening the time food stays in the small intestine, affecting the body's absorption of nutrients in the food, and easily causing diarrhea.

Pay attention to storage hygiene: If cold drinks and cold foods are not stored properly, bacteria will inevitably multiply. Even at a low temperature of -170℃, Escherichia coli, Salmonella typhi and Staphylococcus pyogenes can survive. Therefore, you must make sure the freshness of cold drinks and cold foods before eating.

Crisis 2: Office ladies are susceptible to air conditioning syndrome

Danger Index: ★★★★★

Reason: Office ladies stay in air-conditioned rooms all day long. This long-term air-conditioned environment will cause people to have a series of symptoms of maladaptation to low room temperature. Due to the lack of negative ions in the air and the room temperature being set too low, it often causes dizziness, fatigue, and lack of concentration, which reduces work efficiency. Some people may also experience dry throat, sore throat, joint pain, back pain, and even colds, gastroenteritis, periarthritis of the shoulder, facial nerve paralysis and other symptoms.

Precautions

Reduce the temperature difference between indoors and outdoors: In summer, the temperature in the office should be kept at around 25°C, and the temperature difference between indoors and outdoors should not exceed 7°C. Otherwise, entering the room after sweating will increase the burden on the body temperature regulation center, and in severe cases it may cause disorders in the body temperature regulation center. In addition, the office desk should not be placed where it is directly blown by cold wind, because the air temperature there can be 3 to 4 degrees Celsius lower than other places.

Maintain normal body temperature: If you sit in an air-conditioned office for a long period of time, you should add more clothes that are easy to put on and take off. You can cover your knees with a towel to protect them. At the same time, you should make sure to stand up and walk around occasionally to promote blood circulation in your limbs and enhance your body's resistance.

Open windows for ventilation regularly: The office should ensure that windows are opened regularly for ventilation every day, generally one or two times is appropriate, and ventilation is best in the early morning. Avoid the growth and reproduction of microorganisms caused by poor ventilation and reduce the chance of contracting disease.

Get some proper exercise:

People who live in air-conditioned rooms should spend appropriate time outdoors to improve their ability to "internal regulate" and adapt to temperature differences.

Preventive dietary adjustment: In your daily diet, you can appropriately increase the amount of condiments such as ginger, schizonepeta, perilla leaves, and chili peppers. These can not only serve as a side dish to stimulate the appetite, but can also prevent wind and cold, enhance the body's resistance, and prevent air-conditioning disease.

Crisis 3: Summer skin diseases caused by exposure

Danger Index: ★★★

Reason: The strong ultraviolet rays in summer, coupled with excessive sweat secretion from the body, make it easy to get various skin diseases.

1. Photosensitive dermatosis: This is caused by the body's strong reaction to sunlight and is more common in people with fair skin, people who are sensitive to light, or who ingest sensitive substances such as certain foods or drugs. Prolonged exposure to sunlight on the skin can cause redness, swelling, and even blisters on the back of the hands and face.

2. Skin diseases related to sweat disorders: In hot weather, sweat is not excreted smoothly in the body and accumulates in the skin. Such as prickly heat, dyshidrotic rashes, sweat gland cysts, etc.

3. Microbial infection: A large amount of sweat soaks the skin. If it is not cleaned in time, dust will adhere to it, which can easily lead to infection by staphylococci, streptococci and fungi, and easily cause folliculitis, impetigo, tinea corporis, tinea versicolor and tinea cruris, etc.

Precautions:

Avoid direct sunlight: For people with sensitive skin or allergies, the prevention of photodermatitis mainly involves avoiding direct exposure of photosensitive substances and sunlight to the skin.

Increase vitamin intake: Vitamin B, vitamin C and vitamin E can effectively enhance the skin's resistance and antioxidant capacity, and reduce the damage caused by sunlight to the skin.

The material of clothing is very important: in the hot summer, it is best not to wear clothing that is too tight and not breathable, but to choose soft and comfortable clothes such as spacious and breathable cotton, Lycra, silk and linen. If you are going to be outdoors for a long time, you need to wear light-colored, thin clothes that are highly absorbent and can cover your skin.

Keep your skin clean: Try to clean your face and body every day, change clothes frequently, and keep your body and clothes clean and hygienic.

Crisis 4: Aftereffects of swimming after a happy experience

Danger Index: ★★★

Reasons: 1. Sunburn: The already very strong summer sunlight is refracted by water, and the radiation level is naturally doubled. If you are exposed to strong sunlight for a long time without protection, your skin will easily get sunburned, causing damage to skin fibers, dark spots and wrinkles. Severe sun exposure may also cause skin cancer.

2. Conjunctivitis: Conjunctivitis is one of the common diseases among swimmers, characterized by red and swollen eyes, foreign body sensation, pain and discomfort, etc. A similar disease is epidemic keratitis, the latter of which has more obvious and more severe symptoms.

3. Swimmer's skin rash: The main cause of this skin rash is that the swimming pool water is not clean enough, or it is an allergy caused by some unknown organisms in the sea water. It usually appears in the covered areas of the swimsuit a few hours after leaving the sea water, especially in the compressed areas such as the buttocks and chest. Symptoms include local red papules, rashes or blisters, with itching and burning sensations. Generally, it will heal naturally after 7 to 10 days. If the symptoms are severe, you can take a tablet of astemizole or chlorpheniramine.

Precautions

Take protective measures: apply a few drops of anti-inflammatory and bactericidal eye drops before and after swimming, and it is best to wear waterproof glasses when swimming. If you swim in a swimming pool, you can apply anti-chlorine lotion before swimming. This lotion applied on the body will act as a barrier for the skin, isolating the skin from water with excessive chlorine, thus protecting the skin and preventing the skin from feeling dry due to excessive chlorine in the water.

Clean thoroughly after swimming: Wash your entire body thoroughly with clean water after swimming to reduce the adverse irritation of the chlorine-containing disinfectant in the pool water to the hair and skin, and also to wash away pathogenic microorganisms that may contaminate the skin. You can use a bath lotion such as "swimming lotion" for cleaning. This product can help remove fungi and bacteria, has a skin care effect, and can remove the chlorine smell and bleaching powder on the body after swimming, making the skin clean, smooth and moisturized.

Avoid susceptible periods: Women’s resistance is reduced during menstruation, and swimming and catching cold can easily cause urinary tract infections or recurrence of urinary tract infections. Therefore, swimming should be avoided during this period.

Full body sun protection is very important: If you are swimming outdoors, you should do full body sun protection in advance, apply waterproof and sun-proof skin care products with SPF30 or above, and reapply every 60 minutes to avoid sunburn.

After-sun repair:

1. Soak the cotton pad completely with lotion and put it in the refrigerator for about 10 minutes. After taking it out, use it to gently pat the red and hot areas of the face. Apply it for a few minutes more on the areas that are prone to peeling, such as the tip of the nose, forehead and cheeks. The longer the cooling time, the better, which can reduce the symptoms of redness, swelling and fever of the skin. Or you can cut fresh cucumber into thin slices, soak it in milk, put it in the refrigerator for a while, and then apply it on your face. It can reduce inflammation, relieve pain, and maintain your skin.

2. Dip gauze in saturated saline or water and put it in the refrigerator for about 10 minutes. Take it out and apply it to your shoulders, back, chest and arms for about 20 minutes. Let the cold water soothe the skin and quickly replenish the moisture lost from the epidermis.

3. For dry spots on the skin caused by sunburn, do not try to wipe off the dead skin. Keep the affected area highly moisturized and apply fragrance-free lotion three times a day to dissolve the dry dead skin, reduce roughness and reduce scaly epidermis.
