Can I still travel to Inner Mongolia with thunderstorms and asthma now?

You can go in this situation, but it is not recommended.

If you have severe asthma symptoms or are sensitive to thunderstorm weather, you'd better avoid traveling to avoid aggravating the symptoms. And it is also important to know the weather conditions at the destination. If there are frequent thunderstorms in this area and the air quality is poor, it may have a negative impact on asthma patients, so it depends on the actual situation.
