Most of us like a healthy looking tan and yes we need sunshine for the vitamins it provides but too much exposure is dangerous!
We are all aware of the skin cancers over exposure can cause but perhaps not everyone realises that it is a fact that the sun can be the most destructive element to our skin. It is said that over 90% of the skin's visible signs of aging can be caused by being in the sun too long and letting it burn your skin, what we call getting a "sun tan".
Too much sunshine exposure causes the formation of those free radicals, molecules within the cell structure, causing disruption and damage.
Premature aging of the skin as a result of over exposure can take years before becoming noticeable. Yes, sun related skin damage can take up to 10 years before becoming visible!
Sun safety needs careful consideration and extra care is needed with children. Children need to be made aware of the safety measures at an early age.
Remember use a good sunscreen and apply it at least 15 minutes before you go out into the sun. Reapply liberally and often even though the product may be marked as waterproof.
Cover up if you intend to spend long periods out in the sun, wear a hat of some sort to protect your head.
The safest tan is a Fake Tan but often they do not include sunscreen so if you are out in the sun and you've got on your favourite tan out of the bottle you still need to remember to wear a sunscreen.
But if you must lie in the sun on holiday:
Don't sunbathe between 12noon and 3pm.
Apply sunscreen liberally before you go to the pool or beach.
Reapply sunscreen frequently.
Use after-sun lotions to prevent skin drying out.
We all know that excessive exposure to sunlight can cause skin cancer, wrinkling of the skin, and aging of the skin. However, sunlight is very good for our overall health.
Understanding the power of sunlight is very important. Sunlight intensity is measured in "lux" or "luxes", for example, on a bright sunny day outdoor light can reach three-thousand lux. However, an indoor environment brightly lit will provide only 400 lux. That is less than 15 percent of daylight brightness.
The human body depends on a natural body hormone called melatonin to enhance sleep. Throughout our adult life melatonin decreases, but peaks during childhood. Have you ever wondered why children sleep so much longer and better than adults do?
The body regulates melatonin production carefully. The light-dark cycle largely 우리카지노 controls this process. During the nighttime in a dark environment, melatonin production is at its peak. This process is regulated by the pineal gland, which is located at the center of the brain. The pineal gland serves as a type of "clock" that regulates this process at the right time.
The body does not stockpile melatonin. In order to sleep well at night, we need a moderate supply. In order to boost melatonin output it is known that daily exposure to natural sunlight is a necessity. Manufactured supplements and artificial lights are a weak substitute, and are not worth the effort. The best way to get the melatonin your body needs is to get daily sun exposure.
Nevertheless, there are other benefits of getting adequate sunlight. Sunlight is a potent germ killer. That is why in the olden days people laid their blankets, quilts, and other items out in the sun to be sterilized. Sunlight also gives the skin a healthy glow and makes it smooth and malleable.
A sense of well-being is also attributed to sunlight along with the elevation of mood in most people. Although sun exposure is very beneficial, you must remember to use moderation when you expose yourself to direct sunlight. Acute and chronic depression can also be treated with sunshine along with exercise. Have you ever wondered why we feel so gloomy on a rainy day? During the winter months, try to get as much sunshine as possible.
Vitamin D is another great benefit of the sun's rays. When the sun hits the skin, the body is able to manufacture vitamin D. The body needs vitamin D in order to pick up calcium from the intestines for use in the building of healthy strong bones. Osteoporosis, and both childhood and adult rickets can be prevented with adequate sun exposure.
Other benefits of sunlight also include:
Jumpstarts the immune system
Alleviates pain from swollen arthritic joints
Lower blood cholesterol levels
Relieve certain symptoms of PMS
Did you know?
- PMS, fertility, sleep, and your energy can all be improved with an extra hour of sun light a day.
- Mental health can be affected positively by seasonal variations in light levels. A great indication of this is a person who suffers with seasonal affective disorder (SAD) is treated with light therapy.
- Colon, breast, and prostate cancer are less likely to affect people that get more sunshine.
Although sunlight has many benefits, there are also risk factors. Sunlight can cause skin cancer, especially in light-skinned people. Everyone should be careful and use the necessary precautions before exposing the skin to sunlight over a long period. Healthy living tissue is burned when over exposed to the sun. Skin cancer could become a reality for people who get repeated burns, which can also cause irreversible damage. Premature aging, wrinkling of the skin, oil glands, and skin elasticity can all be damaged due to repeated sunburn and deep tanning of the skin. A high-fat diet along with excessive exposure to the sun is also associated with an increased risk factor to getting skin cancer.
Here are some guidelines for safe, healthy exposure to sunlight:
- Like wearing sunglasses on your skin, modest tanning can be protective. However, you must know your own tolerance to sunlight. Five minutes of sun exposure a day should be a starting point for fair-skinned people and redheads. Ten to fifteen minutes a day could be a starting point for darker skinned people. For most people the ultimate goal should be thirty minutes of sunlight a day.
- Sunburns raise the risk of both malignant melanoma (the deadliest form of cancer), and squamous cell carcinoma, which kills a combined nine-thousand Americans a year. Therefore, it is not wise to burn. If needed wear protective clothing, eyewear, and a protective sunscreen.
- Get your skin ready with proper moisturizing before heading on trips or vacations to hot locations.
- All the vitamin D you need will be provided by five minutes of sunshine on your face and hands each day.
- Lift your spirits, and improve your health by opening your windows and letting the sunlight in each morning.
- There is no substitute for the real thing. Each day should be spent soaking up some sunlight.
