Singapore has narrowly escaped the haze for a good three years. Unfortunately earlier this month, the 24-hour Pollutant Standards Index (PSI) crossed the “unhealthy” range of above 100 once again.
According to the National Environment Agency (NEA), hotspot activities from as many as 115 areas in Sumatra can be expected to persist. Although recent showers have brought some improvement to the haze situation, Singapore may continue to experience hazy conditions depending on the direction of prevailing winds.
The health impact of haze is dependent on one’s health status, the PSI level, as well as the duration and intensity of outdoor activity.
In healthy individuals, short term exposure to haze generally does not cause major health concerns, besides possible irritation to the eyes, nose, and throat.
However, newborns and young children are at higher risk and more susceptible to poor air quality. This is because they are only equipped with an immature immune system and developing lungs.
Some symptoms of adverse reactions to haze are:
Children with pre-existing medical conditions such as asthma, allergic rhinitis, allergic conjunctivitis, and chronic heart conditions may have a higher sensitivity to the haze, and thus experience the symptoms above in more severe forms.
In response to haze, the aforementioned medical conditions may also worsen and flare up. Children with asthma may suffer an asthma attack that requires emergency medical attention.
It is important to note that especially in young children, prolonged exposure to haze conditions over months or years has been linked to increased risk of lung disease, such as reduced lung development, reduced lung function and chronic lung conditions, e.g. asthma and bronchitis.
First and foremost, the key to limiting negative impacts of haze exposure is to limit your child’s outdoor activities and physical exertion.
Other precautions include:
For children with pre-existing medical conditions:
Face masks are unsafe for newborns and N95 masks are not suitable for use in young children. In some cases, face masks may even make your child’s breathing more laboured, potentially worsening any existing breathing difficulty.
It is advised to be alert to any changes in your newborn or young child’s health as well as any symptoms present. Should your child experience breathing difficulties or any severe symptoms, please seek prompt medical care from a qualified paediatrician.
