I wanted to know when one needs to wash hands

Hello and blessings

When you rise in the morning, you should wash your hands three times alternately, right, left, and ideally one should wash from a vessel.

Afterward, one should recite the blessing Al Netilat Yadayim.

Before eating bread, one should wash hands, and it is mandatory to wash from a vessel, twice right and twice left, and recite the blessing Al Netilat Yadayim, and afterward dry the hands.

It is mandatory to wash hands before prayer at least once on each hand, and there is no obligation to wash from a vessel.

And these are things that require washing, but one is not required to pour over the hands three times: one who rises from bed, one who leaves the bathroom and the bathhouse, one who cuts his nails, one who removes his shoes with his hands, one who touches his feet, one who touches his body with his hand, one who combs his head, one who touches lice, one who has marital relations, one who walks among graves, and one who touched a dead body. But if he went near a dead body, washing is not required. Nevertheless, it is customary to wash even when entering for one dead person, and the same applies to those who escort him, and one who did any of these and did not wash his hands: if he is a Torah scholar, his learning is forgotten; if he is not a Torah scholar, he goes out of his mind.

It is not obligatory to recite Shema before midnight, but one should not say the blessing HaMapil with Hashem's name and kingship.
