Ukwelashwa ngokukhanya, i-Photobiomodulation, i-LLLT, i-phototherapy, i-infrared therapy, i-red light therapy njalo njalo, amagama ahlukene ezinto ezifanayo - ukusebenzisa ukukhanya okusebangeni lika-600nm-1000nm emzimbeni. Abantu abaningi bakholelwa ukuthi ukwelashwa ngokukhanya okuvela kuma-LED, kanti abanye basebenzisa ama-laser asezingeni eliphansi. Kungakhathaliseki ukuthi umthombo wokukhanya uyini, abanye abantu babona imiphumela emihle kakhulu, kanti abanye bangase bangaboni okuningi nhlobo.
Isizathu esivame kakhulu salokhu kungafani ukuntuleka kolwazi mayelana nomthamo. Ukuze uphumelele ekwelashweni kokukhanya, okokuqala udinga ukwazi ukuthi ukukhanya kwakho kunamandla kangakanani (emabangeni ahlukene), bese kuba isikhathi esingakanani okufanele ukusebenzise.
Ingabe kukhona okunye okungaphezu kokulinganisa ukwelashwa okulula?
Nakuba ulwazi olubekwe lapha lwanele ukukala umthamo nokubala isikhathi sokusetshenziswa okuvamile, ukukala umthamo wokwelapha okulula kuyindaba eyinkimbinkimbi kakhulu, ngokwesayensi.
I-J/cm² yindlela wonke umuntu alinganisa ngayo umthamo manje, noma kunjalo, umzimba unezilinganiso ezintathu. Umthamo ungalinganiswa futhi ku-J/cm³, okuwukuthi amandla angakanani asetshenziswa kumthamo wamaseli, kunokusebenzisa nje indawo engaphezulu kwesikhumba.
Ingabe i-J/cm² (noma ³) iyindlela enhle yokulinganisa umthamo? Umthamo ongu-1 J/cm² ungasetshenziswa ku-5cm² yesikhumba, kuyilapho umthamo ofanayo ongu-1 J/cm² ungasetshenziswa ku-50cm² yesikhumba. Umthamo ngendawo ngayinye yesikhumba uyafana (1J kanye no-1J) esimweni ngasinye, kodwa amandla aphelele asetshenziswayo (5J vs 50J) ahluke kakhulu, okungenzeka ukuthi kuholele emiphumeleni ehlukene yesistimu.
Amandla ahlukene okukhanya angaba nemiphumela ehlukene. Siyazi ukuthi ukuhlanganiswa kwamandla nesikhathi okulandelayo kunikeza umthamo ofanayo, kodwa imiphumela ngeke ifane ezifundweni:
2mW/cm² x 500secs = 1J/cm²
500mW/cm² x 2sec = 1J/cm²
Imvamisa yeseshini. Kufanele kusetshenziswe kangaki izikhathi zomthamo ofanele? Lokhu kungase kuhluke ezinkingeni ezahlukene. Phakathi kuka-2x ngesonto kanye no-14x ngesonto kuboniswe ukuthi kusebenza kahle ezifundweni.
Isifinyezo
Ukusebenzisa umthamo ofanele kubalulekile ukuze uthole okuningi ekwelashweni kokukhanya. Kudingeka umthamo ophezulu ukuze kukhuthazwe izicubu ezijulile kunesikhumba. Ukuze ubale umthamo wakho, nganoma iyiphi idivayisi, udinga:
Thola ubukhulu bamandla okukhanya kwakho (ku-mW/cm²) ngokukulinganisa emabangeni ahlukene ngemitha yamandla elanga.
Uma unomunye wemikhiqizo yethu, sebenzisa ithebula elingenhla.
Bala umthamo ngefomula: Amandla Ubuningi x Isikhathi = Umthamo
Funa izindlela zokulinganisa umthamo (amandla, isikhathi seseshini, umthamo, imvamisa) eziye zabonakala zisebenza kahle ezifundweni ezifanele zokwelapha ngokukhanya.
Ukusetshenziswa okuvamile kanye nokugcinwa, phakathi kuka-1 no-60J/cm² kungafaneleka
