Kas ir iedegums?

Cilvēki bieži vien pakļauj savu ādu saules staru iedarbībai, lai gūtu „iedegumu”. Bet daudzi nesaprot, ka saules gaisma ļoti spēcīgi iedarbojas uz ādu. Pats svarīgākais iedarbības veids ir iedegums. To izraisa ultravioletais starojums, kas ādā esošo vielu histidīnu pārvērš citā vielā, un tā savukārt paplašina ādas asinsvadus. Tieši tas ir ādas saskārtuma cēlonis.

Ādā ir vēl kāda viela - tirozīns. Ultravioletie stari pārveido tirozīnu brūnā pigmentā, ko sauc par melanīnu. Pēc tam melanīns nokļūst ādas virskārtā, lai aizsargātu to no saules staru turpmākās iedarbības. Šo parādību sauc par iedegumu.

Saules gaismai ir arī labdabīga ietekme uz organismu. Tā iznīcina sēnītes un baktērijas, kas atrodas uz ādas. Saules gaismas ietekmē ādā rodas vielas, kas sašaurina asinsvadus. Tā rezultātā var paaugstināties asinsspiediens.

Turklāt saules gaisma organismā var aktivizēt zināmas šūnas, kas cīnās ar infekcijām. Ar šīs gaismas palīdzību tonizējas muskuļi, tiek stimulētas nervu sistēma. Organismā ultravioletie stari izraisa ķīmiskās pārmaiņas, kuru rezultātā rodas D vitamīns.

Ja nu mēs esam noskaidrojuši, ka saules gaisma dara tik daudz laba, vai tad nebūtu jāsecina, ka cilvēkam vajadzētu centies gūt pēc iespējas tumšāku iedegumu?

Uz šo jautājumu var atbildēt tā: ja zinām, ka saules gaisma uz organismu iedarbojas kā zāles, tad jāraugās, lai šīs zāles mēs saņemtu ar mēru. Ja tu gatavojies iet sauļoties, atceries, ka tas jādara pakāpeniski: dažas minūtes pirmajā dienā, nākamajā – piecas minūtes ilgāk un tā joprojām. Ja saulē uzturēsies pārlieku ilgi, tas var nodarīt ļaunumu gan ādai, gan visam organismam.

I want to use this medium to testify of how i got back my ex husband after divorce, i and my husband have been married for 8 years with 2 kids, we have been a happy family. Last year his behavior towards me and the kids changed, i suspected he was meeting another woman outside out marriage, any time i confronted him, he threatened to divorce me, i did all i could to make hings right but all to no avail until i saw a post on a \"love and relationship forum\" about a spell caster who helps people to cast spell on marriage and relationship issues, when i contacted this spell caster via email, he helped me cast a re-union spell and my husband changed and came apologizing to me and the kids. Contact this great spell caster for your relationship or marriage issues via this email: chiefdrlucky@gmail.com or Whats App him on +2348132777335 Website : http://chiefdrluckysolutionhome.website2.me/ Good luck

Regards everyone my name is Kojonka Moe and i am from Switzerland and i live in the city of Zürich with my family. I have heard about people testify about this company called Abigail Mills and this is my first time applying for a loan online i was afraid to apply for an online loan because of the scam i see on the internet but after i read so many testimonies about this company i decided to give it a try and apply for a loan from this company called Abigail Mills loan company i was in need of money and i needed a loan of 720,000.00 Swiss franc. So i applied and i was told of what to do i was afraid but i gave the company a chance to help me and they assured me that in less than 8 hours time i will receive my loan in my account. I never believed but i was waiting in less than 8 hours time i received a call from my bank that an amount of 720,000.00 Swiss franc was in my account and immediately my bank called me i contacted the company and let them know that i have received my loan and today i am happy. So if you came across my message and you read it and you need a legit loan apply from this company and be rest assured that you will be happy with this company i believe this company is God sent and i pray they last and keep on helping people. Contact this company via mail address abigailmills.loans227@gmail.com
