?While the sun has positive effects such as helping to synthesize vitamin D, improving circulation and increasing metabolic productivity, but too much contact can cause extremely dangerous harms for human health such as thermal shock, exhaustion, skin cancer, etc
?? ?Therefore, we will explore the topic of occupational safety about harms as well as specific and appropriate measures to protect the body at all times of the year.———–

UVA rays contribute to skin damage, especially causing premature aging of the skin.

♻️ Harms of sunlight to the body?

Sunlight consists of spectral rays and others which has different wave length. In particular, UV rays. In particular, UV rays are short wavelengths light, essentially a type of rays harmful to the human body, UV rays will have the most effect when contacting the human’s skin and eyes, reducing body resistance in the long term. UV rays usually have three forms, ultraviolet A (UVA rays), ultraviolet B (UVB rays) and ultraviolet C (UVC rays):

• UVB rays provide energy for the skin to make vitamin D, but it also causes the skin to darken and directly damage DNA.
• UVA rays contribute to skin damage, especially for premature aging
• UVC rays are blocked in the earth’s atmosphere so they do not affect the skin.

1. Severe sunshine affects the skin

• UVA and UVB rays affect the skin which frequently exposed to the sun, attacking the dermis, causing darkened skin and sunburnt
• In addition, high-intensity sun exposure causes wrinkles, causing damage and leading to skin cancer
• Statistics of the American Academy of Dermatology and skin cancer are the most common cancers in the US, with nearly 9,500 Americans diagnosed with skin cancer every day. (According to sonha.vn)
• Skin cancer causes fatal when malignant tumors are formed. In addition, other skin cancers can cause death in many different ways. (According to vietnammoi.vn)

2. Pathogen proliferation

The food is quickly rancid

• In hot and humid weather (especially when the temperature lasts for 37 – 38oC), the food is quickly rancid. Fleas and bacteria proliferate, spread germs through food and drinking water, causing food poisoning, affecting our quality of life.

3. Heat shocking

• Heat shock is a phenomenon when the temperature rises excessively, leading to physical disorders, manifested through increased body temperature gradually turning to red skin and a strong increase in heart rate, a more serious condition occurs such as dizziness, headache even unconscious and fainting.
• As reported by the British Association of Health, up to 59% of strokes happened in the summer are caused by heat shock. The cause is often due to high-intensity activity for a long time in a high-temperature environment. People with chronic diseases such as high blood pressure, diabetes, and thyroid dysfunction are more likely to become victims of heat shock

4. Dehydration and minderals deficiency

• In hot weather, the body gets dehydrated due to excessive sweating, especially for people who exercise a lot, do heavy work or go out in the sun
• Dehydration reduces blood volume, reduce blood through the kidney, reduce urine excretion, and cause metabolic disorders in cells, increase blood-soluble products. Dehydration also reduces important minerals in the body such as potassium (K +), sodium (Na +), chloride (Cl-) …
• Dehydration causes the body to become unbalanced, tired, disturbing the regulation of body temperature, and reducing physical and mental performance

♻️ How to take care health in hot weather?

To ensure health in hot weather, we should do the following hobbies:

1. Drink at least 02 litres of water in 02-03 hours during working time
2. Drink much water before starting work
3. Checking color of urine
4. Take rest time in hot weather
5. Take a long sleep at night
6. In working time, inform to colleagues (direct manager) in case of illness

Hope brothers and sisters comply with the above to ensure the best health
