Is it permissible for a traveler to break their fast in Ramadan if they are exposed to physical, psychological, and nutritional stress?

Fasting Ramadan is one of the pillars of Islam, and it is forbidden to intentionally break the fast without a valid excuse. Whoever intentionally breaks their fast without a valid excuse has committed a grave major sin. As for those with an excuse, such as the sick and the traveler, they are granted permission to break their fast, with the obligation to make up the days they missed. The condition for illness is that fasting would cause harm to the person or inflict an unbearable hardship upon them. As for travel, it is permissible to break the fast if the travel distance reaches four burd (approximately 83 kilometers), provided that the traveler has not intended to stay for four days or more in the destination country.
