If you spend any time outside, you’ve likely heard at least a few warnings about the necessity of wearing sunscreen.
While using sunscreen is preferable to not using it if given the option, choose one that offers broad-spectrum UV protection at least SPF 30. Everybody, regardless of skin tone, should follow these rules. Before going outside in the sun, you should ideally apply sunscreen on your skin for 30 minutes.

Do I need to apply sunscreen to my body every day?
Absolutely! Regardless of the climate, whether it is hot or freezing
Regardless of temperature or cloud cover, UV radiation that causes aging and skin cancer is everywhere, and we should use sunscreen frequently. The development of skin cancer is brought on by UVA and UVB radiations. The primary cause of early skin aging is the deeper penetration of UVA rays. Smaller in wavelength than UVA rays, UVB rays burn skin. Even windows are not a barrier to UVA rays. Therefore, even if you spend the entire day at your desk or driving, you might still expose yourself to harmful UV rays. While UVB radiation peaks in the middle of the day, UVA radiation remains constant throughout the day. It adds up even if you spend the entire day doing errands and getting sunburned.
Does sunscreen have a lifetime?
Since most sunscreens have expiration dates (often three years from the manufacturing date), they should not be used after that point. However, several factors, such as heat exposure (leaving it near the pool, in hot automobiles, etc.), might render the sunscreen less effective than intended. Chemical sunscreens frequently contain components like oxybenzone or avobenzone that can oxidize over time and lose effectiveness. Zinc or titanium-containing mineral sunscreens are often more stable. The lotion may, however, deteriorate with time, causing the chemicals to disperse and the cream to become watery or gritty and useless.
Furthermore, continuous opening and shutting of the bottle might promote the growth of germs in the lotion, which could harm the skin. If you use sunscreen properly (daily, every two hours), you take the time to go through the bottles before the expiration date. You need to wear more sunscreen if it has been over a year since you last used something similar.
How frequently should sunscreen be changed?
If summer is over and you still need to finish a bottle of sunscreen, you haven’t used it frequently enough. I advise using a tablespoon of it on your face and a shot glass-sized amount of body lotion every two hours or more regularly if you exercise or swim (even if the product says it is water-resistant). The consistency shouldn’t alter in any way. Your sunscreen may perform better if you experience clumping or graininess. Additionally, if the bottle starts to smell strange, this may be a sign of a bacterial infection. Replace it if you’re uncertain.
What makes SPF 50 and SPF 75 different from one another?
When sunscreen is applied precisely as instructed, it takes less time for UVB radiation from the sun to cause the skin to get red than it does when it is not. The SPF number represents this difference. The ideal situation would be for skin to burn 30 times slower while applying sunscreen than when it does not. However, it is uncommon to see sunscreen used as recommended. An individual may need more than SPF 30 to be protected compared to another due to genetic variance.
Higher SPFs give consumers a false sense of security, causing them to stay out in the sun longer and apply less frequently, according to studies. Everyone should use SPF 30 or higher, according to several experts. Apply sunscreen 30 minutes before heading outside, and then reapply it every two hours or sooner if you’re swimming or sweating. SPF 100 won’t be twice as effective as SPF 50 because the SPF values aren’t linear. SPF 30 sunscreens offer 97 percent UVB radiation protection, whereas SPF 45 sunscreens offer 98 percent protection.
Keep in mind that SPF only refers to UVB protection and not UVA. Always search for a sunscreen with a broad spectrum designation, which shields against UVA and UVB rays.
How soon after should you reapply?
“Every two hours, but more frequently if you swim or perspire (despite the lotion’s promise to be water-resistant) It is significant to highlight that no product is waterproof, and advertisements for items that claim to be water-resistant are no longer permitted.
What is the least popular area to apply sunscreen?
Your hands’ tops, your feet’s tops, and the tops of your ears. Additionally, I advise using SPF-fortified lip balms and caps to protect hair because many skin malignancies that afflict both older and younger people hide behind their hair.
What should you do if you become sunburned?
Over five sunburns quadruple your chance of developing melanoma! So staying clear of them at all times would be beneficial. However, nobody is perfect, and accidents do occur. Applying cold, moist clothes to the area after or taking a cooling shower to chill it down is crucial. To soothe the skin, apply a soothing moisturizer containing aloe (avoid anything oily or thick that contains petrolatum since these can trap heat and make burning worse).
To relieve inflammation, immediately use a non-steroidal anti-inflammatory (NSAID), such as ibuprofen. The face can also be soothed using 1% hydrocortisone cream, available over-the-counter and used twice daily. Drink a lot of water to restore the fluids and electrolytes in your body. Seek medical treatment if you or your kid has any blisters, fever, chills, or acts disoriented.

Ikiwa unatumia wakati wowote nje, yaelekea umesikia angalau maonyo machache kuhusu uhitaji wa kuvaa krimu ya kujikinga na jua. Ikiwa ni lazima, chagua moja ambayo inatoa ulinzi wa UV wa wigo mkubwa, angalau SPF 30. Kila mtu, bila kujali rangi ya ngozi yake, anapaswa kufuata sheria hizi. Kabla ya kwenda nje, unapaswa kutumia krimu ya kuhifadhi jua kwenye ngozi yako kwa dakika 30. Je, ninahitaji kutumia krimu ya kujikinga na jua kila siku? Bila shaka unaweza! Bila kujali hali ya hewa, iwe ni joto au baridi, bila kujali joto au kifuniko cha mawingu, mionzi ya UV inayosababisha kuzeeka na saratani ya ngozi iko kila mahali, na tunapaswa kutumia kinga ya jua mara kwa mara. Ugonjwa wa kansa ya ngozi huanzishwa na miale ya UVA na UVB. Sababu kuu ya kuzeeka kwa ngozi mapema ni kupenya kwa kina zaidi kwa miale ya UVA. Mwanga wa UV-B ni mdogo kuliko wa UVA, na huwasha ngozi. Hata madirisha hayawezi kuzuia miale ya UVA. Hata kama unakaa mezani au unaendesha gari siku nzima, unaweza kuathiriwa na miale ya UV. Wakati mnururisho wa UVB unapofikia kilele katikati ya siku, mnururisho wa UVA unabaki kuwa wa kawaida siku nzima. Inaongeza hata ikiwa unatumia siku nzima kufanya shughuli na kuchomwa na jua. Je, krimu ya kujikinga na jua huhifadhiwa kwa muda mrefu? Kwa kuwa dawa nyingi za kuondoa jua zinatumia hadi miaka mitatu baada ya kutengenezwa, hazipaswi kutumiwa baada ya hapo. Hata hivyo, mambo kadhaa, kama vile kuathiriwa na joto (kuiacha karibu na dimbwi, katika magari yenye joto, nk. Kwa hivyo, ikiwa unafanya hivyo, unaweza kuharibu ufanisi wa kinga ya jua kuliko ilivyopangwa. Kwa kawaida, dawa za kuondoa jua hutia ndani kemikali kama vile oxybenzone na avobenzone, ambazo zinaweza kuharibika kwa muda na kupoteza ufanisi. Mara nyingi dawa za kuondoa jua zinazotumiwa na madini yenye zinki au titani ni thabiti zaidi. Hata hivyo, lotion hiyo yaweza kuharibika kwa muda, na kusababisha kemikali hizo zitawanyike na krimu iwe na maji au iwe na mchanga na isiweze kutumika. Kwa kuongezea, kufungua na kufunga chupa mara kwa mara kunaweza kuchochea ukuzi wa vijidudu katika lotion, ambavyo vinaweza kuharibu ngozi. Ikiwa unatumia kinga ya jua kwa usahihi (kila siku, kila baada ya saa mbili), utachukua muda wa kupitia chupa kabla ya tarehe ya kumalizika. Unahitaji kutumia krimu ya kujikinga na jua zaidi ikiwa imepita zaidi ya mwaka tangu mara ya mwisho ulipotumia kitu kama hicho. Ni mara ngapi unapaswa kubadilisha krimu ya kujikinga na jua? Kama majira ya joto ni juu na bado unahitaji kumaliza chupa ya sunscreen, wewe si kutumika mara nyingi kutosha. "Kila saa, tumia kijiko kidogo cha mafuta ya mwili kwenye uso wako na kiasi cha ""kioo"" cha kiasi cha maji ya mwili kila saa mbili au zaidi kama unafanya mazoezi au kuogelea (hata kama bidhaa inasema ni sugu kwa maji)." Utaratibu haupaswi kubadilika kwa njia yoyote. Krimu yako ya kujikinga na jua yaweza kufanya kazi vizuri zaidi ikiwa unapata makundi au chembechembe. Kwa kuongezea, ikiwa chupa inaanza kunusa kwa njia isiyo ya kawaida, hilo laweza kuwa ishara ya maambukizo ya bakteria. Badilisha kama wewe ni uhakika. Ni nini tofauti kati ya SPF 50 na SPF 75? Wakati sunscreen ni kutumika hasa kama ilivyoelezwa, inachukua muda mdogo kwa UVB mionzi kutoka jua kusababisha ngozi kupata nyekundu kuliko inafanya wakati si. Nambari ya SPF inawakilisha tofauti hii. Kwa mfano, kwa kawaida ngozi huwaka polepole mara 30 wakati wa kutumia krimu ya kuhifadhi jua kuliko wakati haifanyi hivyo. Hata hivyo, si jambo la kawaida kuona krimu ya kujikinga na jua ikitumiwa kama inavyoonyeshwa. Mtu anaweza kuhitaji zaidi ya SPF 30 ili kuhifadhiwa ikilinganishwa na mwingine kwa sababu ya tofauti ya maumbile. SPF ya juu huwapa watumiaji hisia bandia ya usalama, na kuwafanya waendelee kukaa jua kwa muda mrefu na kutumia mara chache, kulingana na masomo. Kila mtu anapaswa kutumia SPF 30 au zaidi, kulingana na wataalamu kadhaa. Tumia krimu ya kuhifadhi jua dakika 30 kabla ya kwenda nje, na kisha uitumie tena kila baada ya masaa mawili au mapema ikiwa unaogelea au unajipaka jasho. SPF 100 haitaweza kuwa na ufanisi mara mbili kama SPF 50 kwa sababu maadili ya SPF si linear. Kwa mfano, SPF 30 inatoa ulinzi wa asilimia 97 dhidi ya miale ya UVB, na SPF 45 inatoa ulinzi wa asilimia 98. Kumbuka kwamba SPF inahusu tu UVB, sio UVA. "Kila wakati, utafute ""kila wakati"" sunscreen na spectrum pana, ambayo huhifadhi dhidi ya UVA na UVB miale." Ni baada ya muda gani unapaswa kuomba tena? Kila saa mbili, lakini mara nyingi zaidi ikiwa unaogelea au kutokwa na jasho ( licha ya ahadi ya lotion kuwa sugu kwa maji) Ni muhimu kuangazia kwamba hakuna bidhaa sugu kwa maji, na matangazo ya vitu vinavyodai kuwa sugu kwa maji hayaruhusiwi tena. Ni eneo gani ambalo halipendwi sana kutumiwa krimu ya kujikinga na jua? Vipande vya juu vya mikono yako, vichwa vya miguu yako, na vichwa vya masikio yako. Kwa kuongezea, tunashauri kutumia balms za midomo zilizoimarishwa na SPF ili kulinda nywele, kwa sababu uvimbe mwingi wa ngozi ambao huathiri watu wazima na vijana hujificha nyuma ya nywele zao. Unapaswa kufanya nini ikiwa umechomwa na jua? Kuungua kwa jua mara tano au zaidi huongeza mara nne uwezekano wako wa kupatwa na melanoma! Kwa hiyo, ni vizuri kuepuka watu hao wakati wote. Hata hivyo, hakuna mtu mkamilifu, na aksidenti hutukia. Kuchukua nguo baridi na unyevu kwenye eneo hilo au kuoga ili kuifungia ni muhimu. Ili kupunguza joto, tumia mafuta ya aloe (huyo mafuta huhifadhi joto na kuharibu uchomaji). Ili kupunguza uvimbe, mara moja tumia dawa ya kuzuia uvimbe isiyo ya steroidi (NSAID), kama vile ibuprofen. Kwa upande mwingine, unaweza kutumia 1% hydrocortisone cream, ambayo inapatikana mara mbili kwa siku. Kunywa maji mengi ili kurudisha maji na electrolytes katika mwili wako. Tafuta matibabu ikiwa wewe au mtoto wako una vidonda, homa, baridi kali, au ana tabia ya kutoelewana. Pia soma:- Faida za kuvaa miwani ya jua
