Evaluate your room. Design your sleep environment to establish the conditions you need for sleep. Your bedroom should be cool – between 60 and 67 degrees. Your bedroom should also be free from any noise that can disturb your sleep. Finally, your bedroom should be free from any light. Check your room for noises or other distractions. This includes a bed partner's sleep disruptions such as snoring. Consider using blackout curtains, eye shades, ear plugs, "white noise" machines, humidifiers, fans and other devices.
Genes may play a significant role in how much sleep we need. Scientists have identified several genes involved with sleep and sleep disorders, including genes that control the excitability of neurons, and "clock" genes such as Per, tim, and Cry that influence our circadian rhythms and the timing of sleep. Genome-wide association studies have identified sites on various chromosomes that increase our susceptibility to sleep disorders. Also, different genes have been identified with such sleep disorders as familial advanced sleep-phase disorder, narcolepsy, and restless legs syndrome. Some of the genes expressed in the cerebral cortex and other brain areas change their level of expression between sleep and wake. Several genetic models–including the worm, fruit fly, and zebrafish–are helping scientists to identify molecular mechanisms and genetic variants involved in normal sleep and sleep disorders. Additional research will provide better understand of inherited sleep patterns and risks of circadian and sleep disorders.
2. Minimize noise, light, and temperature extremes during sleep with ear plugs, window blinds, or an electric blanket or air conditioner. Even the slightest nighttime noises or luminescent lights can disrupt the quality of your sleep. Try to keep your bedroom at a comfortable temperature -- not too hot (above 75 degrees) or too cold (below 54 degrees).
The influence of tryptophan on sleep continues to be studied in major sleep laboratories across the nation. While this amino acid is not available as a natural dietary supplement or sleep remedy, you can easily include tryptophan in your diet through food sources such as turkey, cheese, nuts, beans, eggs, and milk. You can also boost serotonin levels in the brain -- helping you to feel calm and sleepy -- by eating foods rich in carbohydrates.
Unfortunately, some sleep medications can actually make the problem worse. Sleep aids frequently disrupt sleep cycles, causing less restorative sleep. Even if they help you sleep through the night, the sleep is not necessarily deep or restful. People can become dependent on these meds, requiring them to sleep, and many develop a tolerance to sleep meds over time, requiring more medication to get the same effect. These meds can also cause rebound insomnia, meaning it becomes even harder to fall asleep without the medication. So before you pop that pill for your sleep problems, try these methods instead:
During deep sleep, you get these long-burst brainwaves that are called delta waves, but during REM, your brainwaves are actually functioning very similarly to waking life. Your body is also paralyzed during REM—it’s a very noticeable physiological difference. You also lose thermo-regulation, meaning if it’s hot in your environment, your body gets hot, kind of like you’re a chameleon.
Give yourself some dedicated wind-down time. It doesn’t have to be a full hour or an elaborate routine, but try to spend at least 20 to 30 minutes doing something that relaxes you before you try to fall asleep. That could be taking a warm bath or shower, changing into comfy pajamas and sipping a cup of chamomile tea. Or something completely different — so long as it’s relaxing to you.
