Even with severe asthma, trekking adventures are possible with proper planning and precautions. Before departing with your adventure, ensure you receive medical clearance and establish a regular exercise routine by starting on shorter treks such as Weekend treks in winter or Nag Tibba, Dayara Bhugyal and Bhrigu Lake treks during summer, once these smaller routes have been completed you can explore more challenging routes such as Har Ki Dun or Hampta Pass treks. Persistent unmanaged asthma involves experiencing multiple attacks every week, increasing your risk for Status Asthmaticus. Attacks occur repeatedly without relief, becoming severe and resistant to medication treatment.

As the symptoms progress, you may experience shortness of breath and coughing that worsens at night, becoming especially intense at times of extreme stress or illness. Breathlessness could become so intense that speaking more than a few words becomes impossible (without complete sentences being finished) often necessitating hospitalization for emergency treatment; without prompt therapy and lifesaving injections it could even pose a life-threatening situation; for this reason I strongly advise avoiding trekking for those with uncontrolled asthma as studies on its impact at high altitude has produced mixed findings when applied to asthmatics with serious uncontrolled conditions; studies on both groups produced varied findings in studies regarding its impact; thus I advise against trekking if severe uncontrolled asthma sufferers as it could pose life threatening situations and it might pose potential life threatening situations for them as its effect varied according to studies done over time and studies as high altitude has had both positive and negative outcomes depending on factors. Certain individuals experienced significant immune system shifts, with decreased inflammation allowing them to lower their medication usage and medication costs. But others did not experience positive shifts and remain susceptible to asthma episodes; low oxygen environments and cold temperatures are known to aggravate asthma symptoms while high-altitude environments appear to alleviate them: respiratory infections like the common cold that commonly occur at higher elevations, unidentified allergens; and exercise-induced asthmatic episodes were identified among these triggers.
