The Importance of Sleep

Just how much should you be sleeping every day? How to  get a good night’s sleep?
If you think that sleep is just a period of inactivity, think again. Our nightly shut-eye allows our brains to consolidate our learning and memory so we can perform tasks better the next day. When we have enough sleep, we are less likely to overeat and crave junk, and we make wiser food choices.

If you’ve ever been sleep-deprived, you would have noticed your inability to concentrate, slow responses, impulsive decision-making and even felt easily annoyed. Not to forget those dark eye circles that refuse to budge.

Perhaps sleeping in on the weekends could make you feel better, but what’s lost is lost. Two days of better rest cannot compensate for a week’s worth of impaired performance.

What Is Considered Good Sleep?

The quantity and quality of sleep determine whether you wake up feeling energized or like a walking zombie.

Do’s

Sleep for At Least 7 Hours Daily

Depending on your age, the optimal sleep duration varies. If you are above 18 years old, strive to get at least 7 hours of sleep. See the recommended sleep duration for different age groups below.

Have a Short Nap for Some Energy Booster

Taking a short nap (e.g. averaging 10 to 20-minutes in the afternoon can help recharge your energy level and boost your daytime productivity. Make sure to time it right, taking a nap too close to bedtime can interrupt your nighttime sleep.

Get Active

Exercise regularly as physical activity can help you sleep better.

Relax your Muscles

Release the tension in your body to help you sleep better.

Follow a Bedtime Routine

Wind down from the chaos of the day by calming your senses. Grab a book, take a warm bath, or listen to some soothing music. A consistent routine can signal your body to sleep at the same time daily.

Listen to Relaxing Music

 

Relaxing music can calm your mind and cue your body for some shuteye.

Turn on Your Phone’s Blue Light Filter

The night mode function filters out blue light, which inhibits your brain from producing sleep-inducing hormones[11].

Keep your Sleep Environment Comfortable

Dim or switch off the lights in your room – consider using blackout curtains or eye masks to help block out external lights.

You can also consider using earplugs to remove noise distractions for better sleep. The Importance of Sleep

Don’ts

Avoid Starving or Heavy Meals Before Sleep

It’s hard to sleep when your stomach is rumbling. Eat a couple of hours before sleep, or have a glass of milk before heading to bed. A big dinner may cause discomfort, keeping us wide awake. Also, avoid satiating hunger pangs before bed with large meals¹¹. Instead, have light and healthy snacks like low-fat yoghurt, a cup of milk or a serving of fruit.

Avoid Caffeine or Alcohol At Night

There’s a reason why we drink coffee in the morning – it is a stimulant that promotes wakefulness. While alcohol may make you drowsy, it impacts the quality of your sleep.

Avoid Using Electronics 30 minutes Before Bedtime

Using electronic devices (such as your handphone) before bedtime stimulates your mind, making it harder to fall asleep and stay asleep. Keep them away at least 30 minutes before you go to bed. The Importance of Sleep
