The largest organ in the human body is the skin as it stretches all around the body. It protects the body from external harm, yet it remains very sensitive to touch and the environment around it. The skin faces a variety of dangers including sharp objects, fire and leprosy, but the greatest of them all is sunlight.
Some of the problems that come with sunlight include:
If you are exposed to the sun, a short term effect would be getting sunburns. When your skin gets burnt, it becomes red in color, feels hot and quite painful. The burnt skin might peel off after a few days. To soothe the uncomfortable feeling you can take a cool bath or shower or use soothing creams. You can cool the skin with after-sun lotions that have emollients that counter the tightness and dryness of the skin. For the pain, you can take ibuporefen or paracetamols. However, if you have serious sunburn it is important to consult a doctor.
Make sure that you protect your babies from getting sunburns. If they do get sun burnt, seek medical attention. The sun is not the only source of sunburns as you can also get them from sunlamps and sunbeds.
If your body temperature rises from 37°C, which is the normal body temperature, to 40°C, you suffer from heat exhaustion. If your body gets to that temperature, you will feel sick, sweat excessively, get headaches and even feel faint. Your body is becoming dehydrated because of water loss and might lead to a heat stroke, which can be severe.
To treat heat exhaustion, you should move to a cool place away from direct sunshine and drink a lot of cool liquids. Normally, you will recover within thirty minutes and you will not have any long-term problems. If you do not feel any better after 30 minutes, it is best to seek immediate medical attention.
If your body temperature is above 40°C, you are likely to suffer a heatstroke. In most cases it can be severe. Your body cells will begin to break down, important body functions will stop, some internal organs like the brain might fail, and in very serious cases death mighty occur.
The symptoms of a heatstroke include confusion, feeling sick or vomiting, loss of consciousness and hyperventilation (fast shallow breathing). If you notice this, it is important to seek medical assistance at once.
Treatment involves using intravenous drip to lower the body temperature back to normal.
Out of every 10 skin cancer patients, 8 or 9 of them might have been caused by excessive exposure to the sun. When you keep getting sunburns, your skin becomes damaged and increases the risk of skin cancer. Damaged skin cells are likely to become abnormal and hence cancerous.
Your skin can get damaged if you are often exposed to intense sunlight. This might, however, take a couple of years to happen. The effects of skin damage include brown spots, wrinkling, premature ageing, non-cancerous warty growths (actinic keratosis) and also skin cancer.
When you are exposed to the sun, the skin will produce melanin, a chemical that is meant to protect your skin from excessive UV rays. Melanin takes a few hours to be produced, so it is advisable to only take a few hours in direct sunlight to reduce getting sunburns and also to make sure that your skin is conditioned. Melanin is responsible for giving the skin a tanned glow and if you are very light, it can cause freckles. It is also meant to protect the skin from UV rays. If you are frequently exposed to UV rays and light, melanin might be produced in very low quantities thus lowering your skin's protection.
