To answer your question, Buddhism and Hinduism say that through meditation and and devotion you can attain liberation from the cycle of birth and death. That means will no longer have to take birth and suffer. You will become ONE with the universe (you will get liberated). If you don't take birth you will not have to suffer due to anything, no heat, no cold, no hunger, no disease, no old age, no finances, no attachments.
If you are alive you will have to suffer. I don't have deep understanding of the religion, but there are MANY saints and sages who meditate for decades in the freezing temperatures of Himalayas with very little food, no shelter and very little clothing.
Obviously we common people can't do the same level of meditation, it would be impossible for us to survive.
I think this answers your question, right?
