halacha - If you have problems fasting, what should you do on Tishá BeAv?




Say that, in every 24h fast, you feel extremely nauseated, and then vomit at some point in the final 3 hours. What should you do during a fast like Tishá BeAv?


(Once I asked a Rabbi, and he said that eating according to shiurim is only permitted on Yom Kippur.)


Can you receive a heter not to fast, or to fast until some point in the day before the fast is over?



Answer



That person should be eating at some point in the last 3 hours if there's any risk that the nausea will affect their health (e.g. dehydrate).


The rules are:




  1. Guarding one's health is more important than fasting. Always.





  2. Fasting part of the day is better than not fasting at all. (E.g. children close to Bar/Bat Mitzva are expected to fast a few hours on Yom Kippour).




  3. Shiurim is only relevant to Yom Kippour, and on any other fast once you should not be fasting then you can eat normally.




  4. Those who are not fasting (children, and unhealthy people) should not indulge. Rather they should eat the minimum required - simple foods - to keep healthy. (I.e. Ice cream and bagels is probably not appropriate.)
