Valerian root is a plant with roots that contain many healing properties, in particular for a relaxation and sedative effects. It’s often found in combination with chamomile in a tea. By increasing the amount of gamma aminobutryic acid (GABA), it helps calm the nerve cells in the brain, resulting in a calming effect. GABA works by blocking brain signals that cause anxiety and that ongoing trickle effect that can come from it. This calming effect has made it a favorite natural remedy for anxiety too. (9)
The most important thing is taking that time off—it’s more conducive to your productivity. A lot of times people think they can like fight through and push harder and harder and harder to get better results, but sleep can give you that, too. When you transition in and out of sleep, your brain produces theta waves, which help you think more divergently. That’s why a lot of times when you wake up from a power nap or from sleeping, you’ll be able to solve that intractable problem that you couldn’t earlier in the day. That’s one of the reasons I think taking a break—whether it’s meditation or nap—during that circadian dip can be much more conducive to productivity.
Ongoing sleep deficiency can lower your immune system, making it harder for your body to fight infections. It can trigger mood changes like irritability, depression, and anxiety. And studies have linked insufficient sleep to weight gain; increased risk of developing heart disease, high blood pressure, and type 2 diabetes; and even shorter life expectancy.
In other words, daylight helps your body’s natural clock—which is dictated by the 24-hour cycle of day and night—know when to feel awake and when to feel tired. When your hypothalamus—the gland responsible for regulating sleep and energy levels—senses a change in light, it tells your body to ramp up or ramp down its production of the sleep hormone melatonin. During the day, you feel energized and alert because you don’t produce much melatonin. At night, you produce more, so you feel sleepy.
Journaling. You might think that writing stuff down would make you dwell on it. But when you focus on the things that you appreciate, you might actually sleep better. One recent study, published in Applied Psychology, found that students who wrote in a gratitude journal for just 15 minutes per night worried less at bedtime—and achieved better sleep.
Well, I think the approach to sleep should be really simple stuff first. I’m not a physician, so I can’t give advice about which medications to take and when, but the consensus among the specialists I spoke to was that you should try to get your sleep stability right first, and make sure that you’re getting consolidated sleep and not waking up all the time.
LIGHT: The other thing is no blue light close to bedtime. There are a lot of studies that screen time close to bed is bad. One of the ideal ways of using our app is to connect it to your Bluetooth speakers so that you can put your phone in another room: There is something important to not having your phone in reach, because then you’re looking at the screen and getting the brightness. If you live in the city and there’s bright lights at night, having blackout shade can also be super useful.
Reading books on electronic devices before bedtime disrupts the body’s natural sleep rhythms, according to research published in the Proceedings of the National Academy of Sciences. In the study, 12 people read a book on an electronic device for 4 hours before bed, in a dimly lit room, for 5 consecutive nights. On another 5 nights, they read a real printed book on the same schedule. When using an electronic device, they were less drowsy, took longer to fall asleep, and were less alert in the morning. According to the researchers, use of electronic devices suppressed melatonin levels, making it more difficult to get a good night’s rest.
Anyway, basically your biggest zeitgeber is sunlight, and that’s the environmental cue that controls energy levels as well. But then also timing of meals, exercise, and having a consistent bedtime are all zeitgebers that impact your circadian rhythm. A bigger part of the problem is that we’re indoors so much now, so we don’t get that natural occurring sunlight when you wake up in the morning. That’s one of the best things that you can do to entrench your circadian rhythm.
Experts say that during the teen years, the body's rhythm (sort of like an internal biological clock) is temporarily reset, telling a person to fall asleep later and wake up later. This change might be due to the fact that the brain hormone is produced later at night for teens than it is for kids and adults. This can make it harder for teens to fall asleep early.
A dark, cool bedroom environment helps promote restful sleep. Program the thermostat so the bedroom’s temperature is between 60 and 75 degrees Fahrenheit (experiment to find what works best for you), and use heavy curtains, blackout shades, or an eye mask to block lights. Also be sure to charge phones and laptops outside the bedroom—even this tiny bit of light can disrupt sleep. If you live in a studio or can’t get away from blue lights for any reason, consider making a (very small) investment in blue light blocking glasses.
Use a blue light filter on your device. The blue light emitted by smartphones and tablets can be a powerful sleep disruptor. It suppresses your body’s production of melatonin and throws your circadian rhythm off, making it harder to fall and stay asleep. Luckily, many smartphones these days have a “night shift” feature that adjusts the screen from cool (blue) to warm (yellow) light, which is less likely to keep you up past your bedtime. Likewise, there are apps you can run on your laptop or tablet that reduce blue light. Some popular ones are f.lux and Twilight.
