In the post, which began by quoting lyrics from "My Way" by the late American crooner Frank Sinatra and The Buggles' "Video Killed the Radio Star," Remulla told his constituents that getting a good night's sleep was one of the best ways to strengthen the immune system.
"Curfew isn't just made to reduce nonsense night strolls. It is also meant to strengthen the body through a good and sound sleep," he said.
But one of the most frequent complaints from constituents had been the "tireless abuse" from people singing karaoke, he said.
"This is the favorite hobby of those who have nothing to do from last night until dawn," Remulla said.
"If you're drunk, over the amount of drinking and most of all your excursion is against the time, you can be charged and taken to the precinct on the spot," he wrote. "If you don't want to sleep early, please let yourself sleep! Learn to respect the neighbors who have to wake up at 4 a.m. (like me)."
Karaoke is a favored national pastime in the Philippines. Karaoke bars are dotted across the archipelago and it's common for people to have their own karaoke system at home, making the activity a staple fixture of social events.
The Philippines has reported more coronavirus cases than any other Southeast Asian country, with more than 272,000 confirmed infections, including at least 4,700 deaths, according to data compiled by Johns Hopkins University.

Under the new rules, more businesses will be allowed to reopen, restaurants will be able to offer dine-in services and religious gatherings will be permitted at 30% capacity in the five areas, as long as health protocols are strictly followed, according to the report.
