THE SUN IS GOOD FOR MORALE, BUT NOT ONLY

The sun's rays are dangerous, too, because of the risk of skin cancer . But the sun is also beneficial in many aspects to our health. Here are a thousand and one reasons to enjoy the sun .

Under the sun

The sun is good for your mood
We have a vital need for sun and light more precisely for our morale. In fact, light regulates our internal clock that regulates our essential as sleep and mood.As proof, the famous winter blues that yields after several sessions of exposure to a light emitting natural light. 

The sun is good for bones
Vitamin D is necessary for the binding of calcium on bone. Yet the majority of vitamin D is synthesized by our skin when it is exposed to UVB. Thus, indirectly, the sun is good for our bones, to build a skeleton of good quality to maintain and finally to prevent osteoporosis. Moreover, postmenopausal women with increased risk of osteoporosis often receive supplements of calcium and also vitamin D.
For others, it calls for more outdoor activities: swimming, walking, gardening ... 

The sun is good for our immune system
Again, this effect of the sun exerted indirectly via vitamin D. Indeed, this vitamin, produced by our skin exposed to UVB, looks good against everything.The explanation is that vitamin D plays a central role in activating our immune system. Thus she is involved in the prevention of viral, bacterial, autoimmune, cardiovascular, psychiatric, and even against cancer!

The sun is good against multiple sclerosis
The association between sun and multiple sclerosis was confirmed. Some studies show that the incidence of multiple sclerosis is lower in the sunniest regions. Others suggest that sun exposure (moderate) during childhood reduces the risk of developing multiple sclerosis. This effect of the sun does not appear due to a synthesis of vitamin D, but UV.

Sunlight and acne: pay attention to appearances!
Warning, the sun is good against acne, but only in appearance. On the one hand, the skin thickens to prevent the buttons to hatch and become dry. On the other hand, after exposure, when the skin regains its normal thickness, there is a worsening of acne. Thus, in September, all buttons not explode out during the summer. 

All these benefits are available without sun exposure ups!

Needless to expose himself for hours in the sun and the hottest time of day to get the benefits listed above. Small daily doses in the morning or mid-afternoon are large enough to reap the benefits. 
Thus, the use of artificial UV radiation as issued in tanning salons is useless and even dangerous because they contribute to the risk of skin cancer .

How to prepare your skin to the sun and protect themselves from the excesses?

Moisturize your skin morning and evening. 
At the slightest ray of sunshine and every bit of exposed skin, liberally apply a sunscreen with high index, and repeat applications throughout the day.
Always carry a tube of sunscreen with you, eg if the sun shows up when you have a coffee on the terrace with a girlfriend.
Good news, sunscreen does not prevent our skin synthesize vitamin D! 
Expose yourself very gradually (and always with a sunscreen). 
If you dare not show your legs, you can cheat by using sunless tanners. But beware, the tanned appearance of your skin thus obtained does not make you free sunscreen, or a stroke of sun .
Wear hat, ideal for protecting his eyes and his face (remember that the sun accelerates the aging of the skin and the face and neck are affected first because continuously exposed).
Reminder: Never infant sun!

Protect your eyes absolutely!

UV rays are particularly harmful to eyes. Stinging, redness, tearing and sensitivity to light, are signs of damage to the cornea. UV may also increase the risk of cataracts. So do not take chances, wear glasses sun . Attention to novelty glasses. The tint of glasses (or plastic) promotes the dilation of the pupil, letting more UV easily. Glasses should be filter (UV filter), Category 2 or 3 and the CE marking.
Driving too, wear your glasses sun , against the glare.
