If you're tossing and turning at night and not getting enough sleep, you aren't alone. According to the US Centers for Disease Control and Prevention, more than a third of American adults don't get enough sleep. It happens to all of us but bad sleep is more serious than you might realize. It's associated with the development of chronic conditions such as high blood pressure, heart disease, diabetes and stroke.
Thankfully, you aren't doomed to live with poor sleep. Focusing on your habits around bedtime can go a long way toward achieving better sleep. The 10-3-2-1-0 is a presleep routine that helps your mind and body wind down, prepare for sleep and ensure high-quality rest.
What is the 10-3-2-1-0 sleep hack?Most adults require a good six to nine hours of quality sleep each night. The 10-3-2-1-0 is a presleep routine that helps you relax and signals your body and mind that it's time to wind down. Here is everything you need to know.
10 hours before bed: no more caffeine
Caffeine is the most commonly consumed psychoactive substance in the world. Caffeine consumption should ideally end 10 hours before bed because it can disrupt your sleep-wake cycle when consumed closer to bedtime. The half-life of a single dose of caffeine is about three to seven hours, so your body takes a minimum of 10 hours to eliminate caffeine from your bloodstream. This is a good general rule but 10 hours may be too rigid for some as sensitivity to caffeine varies.
Along with coffee, caffeine may also be present in other drinks, such as sports drinks, soda, energy drinks, some teas and chocolate. Certain medications may also contain caffeine. You must read the labels of medications or drinks you're consuming, to avoid caffeine consumption around your bedtime.
3 hours before bed: no more food or alcohol
Although consumption of alcohol before bed may seem to be relaxing, it is a common disruptor of sleep. It leads to decreased sleep quality and causes frequent overnight awakenings, which ultimately makes you feel tired throughout the next day.
It may also be beneficial to avoid consuming certain foods three hours before bed, as they can lead to heartburn (acid reflux) and disrupt sleep. A few such foods include fried, spicy and high-fat foods. You may also want to avoid foods high in added sugars such as candies, cookies and desserts because they can also lead to poor sleep quality.
2 hours before bed: no more work
You may want to end all work-related activities two hours before bed to ensure you get good quality sleep. Relaxing your mind will help you prepare for sleep. You can practice meditation, muscle relaxation and journaling to calm your mind after work. This helps to create a buffer time zone between your work and sleep time, allowing your brain to slow down and promoting a better quality of sleep.
1 hour before bed: no more screens
It's suggested to avoid using smartphones, televisions, computers, tablets or other devices at least one hour before bed in your actual bed. Blue light before bed is not generally recommended but it is not as disruptive as we once thought. Sleep experts still urge you to avoid using screens in your bed before trying to go to sleep. If your bed is the one place you scroll on your phone or watch TV the most, the body will associate your bed as a place to be awake, making it harder to fall asleep at night.
Hit snooze 0 times in the morning
Hitting the snooze button may disrupt your sleep cycle, making you feel more tired. It's often better to get up with one alarm. The sleep between the alarms is often fragmented and low quality, which may decrease your overall alertness and motivation throughout the day. Along with making you tired, snoozing alarms can also make you late for your daily activities. Additionally, getting up with the first alarm, even if it feels difficult initially, can help reinforce a consistent sleep-wake pattern.
Other sleep hygiene tipsA few common tips that will help to maintain your sleep hygiene and ensure good quality sleep every night include:
Keep electronics out of the bedroom: Keeping electronics out of your bedroom will ensure you are not getting exposed to blue light from them, which can disrupt your sleep-wake cycle.

Avoid late-night exercise: Although exercise is good for your health, doing it one to two hours before bed can disrupt your sleep. Rigorous exercise close to your bedtime can increase your heart rate, adrenaline levels and body temperature, thereby making it difficult for you to fall asleep. Try gentle stretching or yoga poses, instead.
