• Ukunciphisa izimpawu zokudangala kwesizini
• Ukuze ube namandla amaningi futhi imizwa engcono phakathi nezinyanga lapho amahora okukhanya kwelanga ephansi kakhulu.

Ukugeza okukhanyayo kwemvelo

• Thatha umoya okungenani Ihora elingu-1 ngosuku futhi isikhathi eside ezinsukwini ezimpunga, ngisho nasebusika. Ukukhanyisa kwasendlini kuhluke kakhulu ku-spectrum yokukhanya kwelanga futhi akunawo umphumela ofanayo nokukhanya kwangaphandle.
• Vumela ukukhanya kwelanga ngangokunokwenzeka Ngaphakathi ekhaya lakhe. Izindonga ezinemibala ephaphathekile ziqinisekile ukwandisa ukukhanya kwekamelo. Ungakwazi futhi ukubeka ezinye izibuko ezindaweni zamasu.

Ukuzivocavoca umzimba

Uma kwenziwa ngaphandle emini, ukuzivocavoca umzimba kusiza ukuvimbela ukucindezeleka kwesizini. Umkhuba wemidlalo yasebusika nawo wengeza inothi lenjabulo.

Ukusetshenziswa kwezinhlanzi

Phakathi kwabantu base-Iceland, siyaphawula ukucindezeleka okuncane kwesizini uma kuqhathaniswa nabanye abantu basenyakatho. Abanye abacwaningi bathi lokhu kungenxa yokusetshenziswa kwabo okuphezulu inhlanzi futhi izithelo ze Ulwandle². Lawa anothe ngama-omega-3 fatty acids, imisoco ebonakala ilwa nokucindezeleka. Ezinye izici ezihlobene nofuzo kukholakala ukuthi zisiza ukugcina abantu base-Iceland bekude kakhulu nalolu hlobo lokucindezeleka.²⁷. Lezi kusengama-hypotheses. Ngalesi sikhathi, umthelela ukusetshenziswa kwe-omega-3 okungenzeka kube nawo ezimpawini zokudangala kwesizini awaziwa.²⁸.
