Kas ir iedegums?

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.
