A Malaysian man has urged the public to reconsider exercising outdoors during hazy conditions after he developed a persistent cough and began coughing up blood in his phlegm.
According to Sin Chew Daily, the man had been coughing for nearly a week and a half after taking part in outdoor training sessions when the air quality was poor.
His condition subsequently worsened, with blood appearing in his phlegm. The cause of his symptoms has not been confirmed.
Man Undergoes Tests For Suspected Lung Infection
The man reportedly suspected that his symptoms could be linked to his exposure to the haze while exercising outdoors.
He was at the hospital awaiting the results of a chest X-ray and a phlegm sample test as doctors investigated a possible lung infection.
However, there has been no confirmation that the haze was responsible for his condition. His experience has nevertheless prompted him to warn others against underestimating the potential health risks associated with prolonged exposure to polluted air.
Urges Runners To Exercise Indoors During Haze
Following his health scare, the man advised people planning to run, jog or participate in other outdoor activities to consider moving their workouts indoors temporarily.
He also encouraged the public to take precautions rather than continue exercising outdoors when air quality deteriorates, stressing that the haze should not be taken lightly.
For those who exercise regularly, switching to an indoor gym or working out at home could help reduce exposure to airborne pollutants during periods of poor air quality.
Haze Can Affect Respiratory Health
Sin Chew Daily also reported that Malaysia’s Ministry of Health had advised the public to minimise outdoor activities, particularly strenuous exercise, during hazy conditions.
One concern is PM2.5, a category of fine particulate matter small enough to penetrate deep into the respiratory system.
Exposure to these particles may cause coughing, throat irritation and breathing difficulties. It can also aggravate existing respiratory and cardiovascular conditions, including asthma and heart disease.
The ministry advised the public to avoid outdoor activities as much as possible when Malaysia’s Air Pollutant Index (API) exceeds 100, which falls within the unhealthy range.
People who need to venture outdoors during periods of poor air quality may consider wearing a properly fitted N95 mask to reduce exposure to fine particles.
Anyone experiencing persistent coughing, blood in their phlegm, chest discomfort or breathing difficulties should seek prompt medical assessment rather than assume the symptoms are caused by the haze.
While the Malaysian man’s diagnosis remains unconfirmed, his experience serves as a reminder to pay attention to air quality and adjust outdoor exercise routines when conditions worsen.
