According to the World Health Organization, global obesity has nearly tripled since 1975, with 1.9 billion adults considered overweight and 650 million obese in 2016. Singapore has not been immune to this worldwide weight problem.
In fact, more than one-third of adults in Singapore qualified as overweight in the MOH’s most recent National Population Health Survey.
Of course, a combination of exercise and a healthy diet is key to maintaining a healthy weight. However, studies have uncovered a few surprising factors within everyday life that could have an impact on your waistline.
1. Traffic Sounds Can Drive Subconscious Stress-Eating
Quite a few articles have already covered how loud music in restaurants can trigger faster eating and less-healthy meal choices. What’s less mentioned, however, is that the traffic noises–whether actively noticed or not–can induce excessive eating beyond fullness.
In fact, a 4-year study by the Karolinska Institute in Sweden revealed that people’s waistlines increased by nearly one centimetre per 10-decibel rise in traffic noise. To put this into perspective, 10-decibels is roughly equivalent to the sound of falling leaves. What’s more, people exposed to airplane noise in a follow-up study experienced a six-cm increase in waist size.
Scientists explain this sound-reactive overeating as a displacement activity, distracting from environmental stress.
While it may be difficult to avoid traffic and plane noise altogether, there are a few ways to mitigate the impact:
• If you’re looking to move, consider avoiding noisy neighborhoods (Serangoon, Orchard, Outram, Bukit Timah and Clementi are amongst the loudest).
• If you’re already settled, you may want to consider sound-proofing your flat. A few simple fixes include adding a seal to the bottom of your door and purchasing sound block curtains. More comprehensive solutions, however–false ceilings, laminate or double-glazed windows, and floated insulated walls to name a few–cost more because they involve renovation, which can be facilitated by a personal loan.
2. Blue Light from Smartphones Can Build Up Your Blood Sugar
The light our bodies are exposed to has a strong impact on our sleeping behavior, hormone production, and yes – metabolism. This is especially true with blue light, an artificial light emitted by electronics like computers, laptops, tablets, and smartphones.
Research by Northwestern Medicine has shown that exposure to such light (including while eating) can increase insulin resistance and cause higher blood sugar levels. This build-up, in turn, is linked to increased body fat, weight gain and a greater risk of diabetes. This is especially alarming, given Singaporeans spend an average of over 12 hours per day on digital devices, mostly on their mobile phone.
Fortunately, consumers now have greater control over their exposure to blue light. Both iPhones and Android devices, for example, have built-in options in their settings that shift the screen’s color temperature. Even more, there is a variety of Blue Light Apps available on the marketplace.
Even still, consumers must be the ones to remember to make these changes, as factory settings remain blue and bright. It’s also worthwhile to spend more time off-screen, whether by reading a book or just spending time with friends and family.
