- ukhula umbhede wezimbali, ukuvimbela ukusakazwa kokhula;

- entwasahlobo nasekwindla, phatha ama-roses nge-sulfate yethusi ngensipho;
- ekwindla, susa wonke amahlamvu owomile ngaphansi kwesihlahla ugaye inhlabathi.
Ngaphezu kwalokho, kubalulekile, noma esigabeni sokutshala izithombo, ukukhetha indawo enokhanyayo futhi engenawo umoya, futhi lapho wephula irosari, shiya ibanga elanele phakathi kwezihlahla.
