According to a 2011 study published in the Journal of Neuroscience, salt can help lower cortisol levels and balance blood sugar levels, which is what you want at night for restful sleep. Natural sugars can help by elevating insulin slightly, which helps lower cortisol (this is one of the reasons my doctor suggests consuming carbohydrates at night and not in the morning if you are trying to balance hormones).
A smart tip for jetsetters: Pack melatonin supplements, such as Natrol Melatonin Fast Dissolve Tablets. The supplement helps your body better adjust to the new time zone, allowing you to fall asleep come bedtime and avoid jet lag. But the sleep aid isn’t just for jet lag. You can also pop the tablets when you have occasional sleepiness or when your sleep schedule shifts and you need to get your body into sleep mode. It’s recommended that you start with a small 1 mg dose (take it 20 minutes before bedtime). You can slowly increase your dosage, but don’t exceed 10 mg.
Some researchers, parents, and teachers have suggested that middle- and high-school classes begin later in the morning to accommodate teens' need for more sleep. Some schools have implemented later start times. You and your friends, parents, and teachers can lobby for later start times at your school, but in the meantime you'll have to make your own adjustments.
One of the vital roles of sleep is to help us solidify and consolidate memories. As we go about our day, our brains take in an incredible amount of information. Rather than being directly logged and recorded, however, these facts and experiences first need to be processed and stored; and many of these steps happen while we sleep. Overnight, bits and pieces of information are transferred from more tentative, short-term memory to stronger, long-term memory—a process called "consolidation." Researchers have also shown that after people sleep, they tend to retain information and perform better on memory tasks. Our bodies all require long periods of sleep in order to restore and rejuvenate, to grow muscle, repair tissue, and synthesize hormones.
Keep precautions in mind. Diphenhydramine and doxylamine aren't recommended for people who have closed-angle glaucoma, asthma, chronic obstructive pulmonary disease, sleep apnea, severe liver disease, digestive system obstruction or urinary retention. In addition, sleep aids pose risks for women who are pregnant or breast-feeding, and might pose risks to people over age 75, including an increased risk of strokes and dementia.
There is a big difference between the amount of sleep you can get by on and the amount you need to function optimally. According to the National Institutes of Health, the average adult sleeps less than seven hours per night. In today’s fast-paced society, six or seven hours of sleep may sound pretty good. In reality, though, it’s a recipe for chronic sleep deprivation.
We tend to think of sleep as a time when the mind and body shut down. But this is not the case; sleep is an active period in which a lot of important processing, restoration, and strengthening occurs. Exactly how this happens and why our bodies are programmed for such a long period of slumber is still somewhat of a mystery. But scientists do understand some of sleep's critical functions, and the reasons we need it for optimal health and wellbeing.
Many herbal tonics support adrenal health and help balance energy levels, which allow us to work, exercise, and digest during the day, then drop into an alpha state during the night. My favorite herb for insomnia is ashwagandha, which helps to relax the body. Try 500–1,000 mg at bedtime for 6–12 months until you re-establish a healthy sleep pattern. Other effective bedtime herbs include valerian (especially if pain is part of your disturbed sleep quality), passionflower, lemon balm, and California poppy.
Wear socks to bed. While a cooler core body temperature helps you fall asleep faster and get more restful sleep, cold extremities (hands and feet) can have the opposite effect. If you tend to have cold feet at bedtime, put on a pair of cozy socks, rest your feet on a heating pad, or pile an extra blanket on the foot of your bed. If none of those appeal to you, try wearing a pair of warm slippers in the evening so that your feet will be toasty when you climb in bed for the night.
