Today's My Paper coffee giveaway has been postponed due to the haze.
My Paper had invited readers to head to One Raffles Place to score Ah Huat White Coffee freebies.
The giveaway, which would have seen readers winning attractive prizes as well, will now be held at a later date.
This is in line with the National Environment Agency's recommendation that, when Pollutant Standards Index (PSI) readings go above 100, children, seniors and people with existing heart or respiratory ailments should reduce physical exertion and outdoor activity.
For the rest, they should reduce vigourous outdoor activity.
Yesterday, the PSI shot up to a record high of 371 at 1pm. A PSI reading above 300 is considered hazardous.
