Stimulating the formation of hemoglobin, preventing and combating rickets, preventing skin diseases (psoriasis), the beneficial influence on the nervous system, increasing resistance to infections, and stimulating the production of vitamin D, are just some of the benefits of moderate sun exposure.
Through the process of tanning, the skin actually tends to fend off the rays of the sun. Under the stimulation of radiation, the melanocytes release melanin, a protein substance able to absorb UV rays and block their action before they cause damage to skin layers. Melanin is synthesized from tyrosine under the influence of an enzyme called tyrosinase. The main role of melanin is to absorb UV radiation and protect us from the effects that can be extremely unpleasant (sunburns and premature aging, triggering skin cancer, etc.). But melanin alone can not provide full protection so that it is absolutely necessary to protect our skin by using cosmetics to act as a solar filter and to feed and care for the skin after sun exposure.
To prevent sunburns you have several options: you can apply protective creams with high SPF, nourish the skin after exposure to sunlight with a moisturizer and you can avoid sun exposure during peak hours between 11 and 15. And to restore water balance of the body consume at least 2 liters of fluid a day to replace the water your body loses from perspiration.
If you do happen to forget to use and your skin suffered sunburns, you can try using several natural remedies.
Coconut oil: apply a little oil to sunburned skin to attenuate them and to moisturize and heal the skin;
Milk: a piece of gauze soaked in milk and then applied on the affected areas soothes the pain caused by sunburns;
Sandalwood and turmeric, these herbs have a cooling effect on the skin: an ancient Ayurvedic remedy teaches us to make a paste of turmeric and sandalwood mixing them in equal amounts and adding a little cold water. Apply the paste on the sunburned surface and leave it for 15-20 minutes;
Baking soda: Add a few tablespoons of baking soda in the bath water and stay there no more than 15-20 minutes. If you stay more you risk to dry your skin too much.When you’re done, resist the temptation to wipe your skin.
Potatoes: Wash two potatoes, cut them into pieces and put them in a blender until they become liquid and if the mixture seems too dry, add water until it becomes a solution. Spray the solution on the sunburnt areas and wait until dry and then take a shower with lukewarm water.
Marigold oil has emollient, soothing, anti-inflammatory and healing properties on sensitive or irritated skin.
Avocado: to soften the dry skin use the pulp of a ripe avocado.
Peppermint: to ease painful sensations wash the area with cold mint tea. Mint is known for its decongestant and antiseptic properties. You can use fresh mint leaves, or a few drops of peppermint essential oil in bathwater.
Chamomile: Known since antiquity for its soothing, decongestant and antiseptic actions. You can use cold compresses with chamomile infusion (applied every two to three hours) that relieve pain and swelling and repair the skin.
