Importance Of Sunlight For The Survival Of Human Life

The sun and sunlight are essential for the survival of life. Summer months are times of happiness, of sunbathing on beaches, freedom from winter wear, and freedom from the gloominess and darkness of winter. When we expose our skin to sunlight, our bodies release serotonin which has mood-enhancing properties. Exposure to sunlight is essential for the production of adequate vitamin D and strong bones in our bodies. Sufficient exposure to sunlight also helps prevent certain cancers. The healing properties of sunlight are required to treat skin diseases like psoriasis and jaundice. While sunlight has many healing properties, it does have detrimental effects too, which is why the use of sunscreen lotion is advised by dermatologists.

Reasons For Using Sunscreen Lotions

Sunscreen lotions protect our skin from sunburn and damage from the ultraviolet effects of sunrays. Sunscreen also comes as gels, sprays, and ointments. The sun protection factor or SPF determines how strong or effective the sunscreen is. The greater the SPF the better the sunscreen is. UV protection is required if your skin is going to be exposed to sunlight for more than 15 minutes, whether you are indoors or outdoors. The lotion has to be applied liberally over all exposed skin areas and has to be reapplied every 2 hours. It is to be applied more frequently if you are going to be swimming or in water.

Disadvantages Of Overexposure To The Sun

There is great emphasis on the use of sunscreen lotions or creams because of the increasing incidents of skin cancer. Skin ageing and wrinkles on the skin are also due to excessive exposure to the sun. People with light skin types are more at risk for developing cancer because they have less pigmentation. Pigmentation is a natural protection from the burning effects of the sun. It is not just sufficient to choose a sunscreen and apply it. It is important to choose the best sun protection cream from the wide variety available in the market. Sunscreens work either by scattering or reflecting the light away from your body or by absorbing the UV rays and not allowing it to touch the skin.

Choosing Broad Spectrum Sun Protection Creams For Adequate Protection

Research has led to the introduction of highly sophisticated sunscreens in the market. Initially people just checked the SPF content of the sunscreen to buy it. The new broad spectrum sunscreens available protect the skin from the harmful effects of both ultraviolet A and B rays. The best sun protection creams should contain ingredients like avobenzone, titanium dioxide, zinc oxide, ecamsule, and oxybenzone. People like swimmers who need to spend many hours in the water need to use sunscreens that are water resistant and will be effective even after 80 minutes in the water.

Dermatologists have been advocating the use of sunscreen lotions and broad spectrum sun protection creams to protect the skin from the harmful effects of the sun.
