The more overstimulated your brain becomes during the day, the harder it can be slow down and unwind at night. During the day, many of us overstress our brains by constantly interrupting tasks to check our phones, emails, or social media. Try to set aside specific times for these things, and focus on one task at a time. When it comes to getting to sleep at night, your brain won’t be accustomed to seeking fresh stimulation and you’ll be better able to unwind.
Did you know that a lack of exposure to sunlight may be interfering with your sleep quality? Light exposure is crucial to our circadian rhythms (aka our internal clocks), which control vital biological processes including sleep. Scientific research reveals that that a lack of light in the workplace results in poorer overall sleep quality, as well as sleep disturbances, which can then have further negative effects on health.
Taking a nap might seem counter-intuitive to good nighttime sleep, but short naps of 10 to 30 minutes actually help you gain extra energy during the day and don’t disrupt your sleep. Even a 10-minute nap can improve your alertness for 2-and-a-half hours if you’re sleep-deprived, and you can feel the benefit for up to 4 hours if you are well-rested.
Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body – from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of disorders including high blood pressure, cardiovascular disease, diabetes, depression, and obesity.
Sedative-hypnotic medications (benzodiazepines and non-benzodiazepines) can cause severe allergic reaction, facial swelling, memory lapses, hallucinations, suicidal thoughts or actions, and complex sleep-related behaviors like sleep-walking, sleep-driving (driving while not fully awake, with no memory of the event) and sleep-eating (eating in the middle of the night with no recollection, often resulting in weight-gain). If you experience any unusual sleep-related behavior, consult your doctor immediately.
Studies have shown that exercise during the day can improve sleep at night. When we exercise, we experience a significant rise in body temperature, followed a few hours later by a significant drop. This drop in body temperature makes it easier for us to fall and stay asleep. The best time to exercise is late afternoon or early evening, rather than just before bed. Aim for at least 30 minutes four times a week. Aerobic exercises are the best to combat insomnia as they increase the amount of oxygen that reaches the blood.
Did you know your internal body temperature is integral to regulating your biological body clock? When you’re falling asleep, your body temperature drops slightly, which some experts believe actually helps the process along, according to the Harvard Medical School. The National Sleep Foundation recommends a bedroom temperature of 60 to 67 degrees F for the most sleep-friendly conditions.
For those who have difficulty with insomnia, there are a handful of options to help you sleep. One treatment option is sleep restriction. This involves limiting the amount of time that you spend in bed (often to 7-8 hours) so that the time you are there you are more likely to spend asleep. It can also be useful to observe a behavioral change called stimulus control. Stimulus control helps break the association between your bedroom and not being able to sleep.
Forget the glass of wine—winding down the day with a warm mug of milk and honey is one of the better natural sleep remedies. Milk contains the sleep-inducing amino acid tryptophan, which increases the amount of serotonin, a hormone that works as a natural sedative, in the brain. Carbs, like honey, help transmit that hormone to your brain faster. If you’re hungry for a snack, a turkey sandwich will deliver that power-combo of tryptophan and carbohydrates; or try a banana with milk to get some vitamin B6, which helps convert tryptophan to serotonin.

REM sleep are particularly important. You can ensure you get more deep sleep by avoiding alcohol, nicotine, and being woken during the night by noise or light. While improving your overall sleep will increase REM sleep, you can also try sleeping an extra 30 minutes to an hour in the morning, when REM sleep stages are longer. See The Biology of Sleep to learn more.
Adjust the thermostat. If you’re too hot or too cold at bedtime, sleep isn’t going to come easy. While there’s no ideal temperature for everyone, most people sleep comfortably when the bedroom is between 60 and 67 degrees. As you start to feel drowsy, your body temperature drops, which in turn helps you drift off to sleep. A cooler bedroom facilitates that. Don’t cool it off too much, though — shivering in bed isn’t conducive to a good night’s sleep.
