MB 8: And even initially - The Taz writes that we can learn from this that if a person is thirsty at night after going to bed, when it is impossible for him to wash his hands and say the blessing (*), he should think the blessing in his heart and drink. And the Mate Yehuda argues with this opinion, and he writes that since it is possible for such a person to get up and go wash his hands, it is not similar to a person who is ill or has no choice - because we do not use cases where there was no alternative as models to judge cases with alternatives. Even if he does not have enough water to wash his hands and drink as well, or it is difficult for him to stand because of the cold, he can still clean his hands on a wall or anything else that will clean them off, and this is sufficient even if he knows with certainty that his hands touched a normally covered part of his body - as above in 4:22 and 23. [* - Remember that this was at a time when water was not available in the next room of a heated apartment, but rather one needed to bundle up against the Russian winter to go outside and pump it from a well. One is required to wash one's hands if he has touched a normally covered part of his body - and the assumption is that one did so while sleeping for any length of time. -- YM]
MB 9: As long as the place - If the place is completely dirty, he should not think the words of the Shema or the blessings; rather he should think in his heart that he is required to say it but cannot do so, and feel pain over this, and HaShem will see into his heart to give him reward for his thought, because he has no other option. And it seems obvious that those who take a drink while inside a bathhouse are not following the law, because while there it is forbidden to even think words of Torah, and there is nothing forcing him to take a drink inside. [No one does this today; again, we have hot & cold running water. -- YM] And see later in Siman 84 what I will write there in the name of the Pri Megadim, concerning this subject.
62:5. The Chazan must raise his voice when saying "Shema Yisroel [Hear, Israel]" in order that the congregation should hear him and give Kingship to the name of Heaven together.
