When Islington 2000 was under construction, popcorn ceilings were an obvious choice. The bumpy finish was easy to install, hid imperfections, and discouraged both fire and noise. If you still have the stippled finish you are still benefitting from these advantages.

Current taste has moved away from a focus on these practical issues and toward the modern look of smooth finishes on our ceilings. If you are inclined to make your ceiling smooth there are options. Scraping/sanding is the worst – the dust can be toxic.

Popcorn ceilings in big rooms can be covered with 3/8” drywall. This will lower the ceiling a very little. In a condo remember that the building is designed to sway which may in time expose cracks. More creative options for covering the stipple are decorative ceiling tiles or wooden planks. Both offer warmth and visual appeal.

A newer option for creating a smooth surface is to tightly stretch fabric or pvc across the existing ceiling. Installers work with an aluminum frame attached to the ceiling, then stretch the membrane of your choice over all. Besides a sleek look this improves acoustics. And the space above a stretched ceiling can include various kinds of ambient lighting options. 

A plasterer can skim-coat the whole ceiling. It may require multiple coats to even out a very textured ceiling, because it is not advisable to prepare the surface by sanding. As mentioned above, it is best to avoid any contact with possibly toxic construction dust.

The least expensive and least fussy option is to paint over the textured ceiling. An acrylic/latex paint in a flat or matte finish, possibly in a darker colour will visually camouflage the texture. It is decorative and also works as a sealant. Lay down multiple coats very thickly for best results.

Getting sufficient sleep is important for good health. However, authoritative statistics on insomnia worldwide suggest that 16.2% of the global population suffers from insomnia, and 7.9% have severe insomnia. A survey study in the US conducted by the Centers for Disease Control and Prevention found that adults had trouble falling or staying asleep within a 30-day period.

A recent scientific meta-study examined the outcomes of 22 randomized controlled trials investigating the effects of exercise and other therapies for insomnia, and found that four types of exercise may be the best ways to improve sleep quality and avoid insomnia: yoga, Tai Chi, walking, and jogging.

The study found that practicing yoga, Tai Chi, walking, and jogging are effective therapies for treating poor sleep and insomnia. The positive effects of yoga were the strongest of the exercises studied, and the beneficial effects of Tai Chi were the longest-lasting. The conclusions of the study were:

• Practicing yoga may increase sleep time by just under two hours a night and boost sleep
  efficiency by 15%. It may also shorten the amount of time it takes to fall asleep and wake
  up after having been asleep.
• Tai Chi may improve sleep quality, increase total sleep time by nearly an hour, reduce
  wake after sleep onset, and shorten sleep onset latency. The beneficial effects of Tai Chi
  were especially long-lasting: as long as two years.
• Walking or jogging may result in an almost 10-point reduction in insomnia severity
  scores.
• For people seeking better sleep, yoga, tai chi, walking, and jogging may be as effective
  as cognitive behavioural therapy for insomnia.
• Seven to nine hours is the recommended amount of sleep each night for adults.
