Doing Something about It
Beyond the obvious sleep benefits of thinking clearly and staying healthy, the ability to manage your emotions and remain calm under pressure has a direct link to your performance. TalentSmart has conducted research with more than a million people, and we’ve found that 90% of top performers are high in emotional intelligence (EQ). These individuals are skilled at understanding and using emotions to their benefit, and good sleep hygiene is one of the greatest tools at their disposal.
High-EQ individuals know it's not just how much you sleep that matters, but also how you sleep. When life gets in the way of getting the amount of sleep you need, it's absolutely essential that you increase the quality of your sleep through good sleep hygiene. There are many hidden killers of quality sleep. The 10 strategies that follow will help you identify these killers and clean up your sleep hygiene. Follow them, and you'll reap the performance and health benefits that come with getting the right quantity and quality of sleep.
1. Stay Away from Sleeping Pills
When I say sleeping pills, I mean anything you take that sedates you so that you can sleep. Whether it's alcohol, Nyquil, Benadryl, Valium, Ambien, or what have you, these substances greatly disrupt your brain's natural sleep process. Have you ever noticed that sedatives can give you some really strange dreams? As you sleep and your brain removes harmful toxins, it cycles through an elaborate series of stages, at times shuffling through the day’s memories and storing or discarding them (which causes dreams). Sedation interferes with these cycles, altering the brain's natural process.
Anything that interferes with the brain's natural sleep process has dire consequences for the quality of your sleep. Many of the strategies that follow eliminate factors that disrupt this recovery process. If getting off sleeping pills proves difficult, make certain you try some of the other strategies (such as cutting down on caffeine) that will make it easier for you to fall asleep naturally and reduce your dependence upon sedatives.
2. Stop Drinking Caffeine (at Least after Lunch)
You can sleep more and vastly improve the quality of the sleep you get by reducing your caffeine intake. Caffeine is a powerful stimulant that interferes with sleep by increasing adrenaline production and blocking sleep-inducing chemicals in the brain. Caffeine has a 6-hour half-life, which means it takes a full 24 hours to work its way out of your system. Have a cup of joe at 8 a.m., and you’ll still have 25% of the caffeine in your body at 8 p.m. Anything you drink after noon will still be near 50% strength at bedtime. Any caffeine in your bloodstream—the negative effects increasing with the dose—makes it harder to fall and stay asleep.
When you do finally fall asleep, the worst is yet to come. Caffeine disrupts the quality of your sleep by reducing rapid eye movement (REM) sleep, the deep sleep when your body recuperates most. When caffeine disrupts your sleep, you wake up the next day with a cognitive and emotional handicap. You’ll be naturally inclined to grab a cup of coffee or an energy drink to try to make yourself feel more alert, which very quickly creates a vicious cycle.
3. Avoid Blue Light at Night
This is a big one—most people don't even realize it impacts their sleep. Short-wavelength blue light plays an important role in your mood, energy level, and sleep quality. In the morning, sunlight contains high concentrations of this "blue" light. When your eyes are exposed to it directly (not through a window or while wearing sunglasses), the blue light halts production of the sleep-inducing hormone melatonin and makes you feel more alert. This is great, and exposure to a.m. sunlight can improve your mood and energy levels. If the sun isn't an option for you, try a blue light device.
In the afternoon, the sun's rays lose their blue light, which allows your body to produce melatonin and start making you sleepy. By the evening, your brain does not expect any blue light exposure and is very sensitive to it. The problem this creates for sleep is that most of our favorite evening devices—laptops, tablets, televisions, and mobile phones—emit short-wavelength blue light. And in the case of your laptop, tablet, and phone, they do so brightly and right in your face. This exposure impairs melatonin production and interferes with your ability to fall asleep as well as with the quality of your sleep once you do nod off. Remember, the sleep cycle is a daylong process for your brain. When you confuse your brain by exposing it in the evening to what it thinks is a.m. sunlight, this derails the entire process with effects that linger long after you power down. The best thing you can do is avoid these devices after dinner (television is okay for most people as long as they sit far enough away from the set). If you must use one of these devices in the evening, you can limit your exposure with a filter or protective eye wear.
4. Wake Up at the Same Time Every Day
Consistency is key to a good night's sleep, especially when it comes to waking up. Waking up at the same time every day improves your mood and sleep quality by regulating your circadian rhythm. When you have a consistent wake-up time, your brain acclimates to this and moves through the sleep cycle in preparation for you to feel rested and alert at your wake-up time. Roughly an hour before you wake, hormone levels increase gradually (along with your body temperature and blood pressure), causing you to become more alert. This is why you'll often find yourself waking up right before your alarm goes off.
When you don't wake up at the same time every day, your brain doesn't know when to complete the sleep process and when it should prepare you to be awake. Long ago, sunlight ensured a consistent wake-up time. These days, an alarm is the only way most people can pull this off, and doing this successfully requires resisting the temptation to sleep in when you're feeling tired because you know you'll actually feel better by keeping your wake-up time in tact.
5. No Binge Sleeping (In) on the Weekend
Sleeping in on the weekend is a counterproductive way to catch up on your sleep. It messes with your circadian rhythm by giving you an inconsistent wake-up time. When you wake up at the same time during the work week but sleep past this time on the weekend, you end up feeling groggy and tired because your brain hasn't prepared your body to be awake. This isn't a big deal on your day off, but it makes you less productive on Monday because it throws your cycle off and makes it hard to get going again on your regular schedule.
