What is the one thing we (probably) all need more of, yet sacrifice the most? SLEEP! You may grab an extra nine minutes with every hit of the snooze button, but unless you’ve had hours of quality sleep before your alarm, it’s probably not helping much. This week, we’re here to show you how beneficial sleep is to your body and brain, and what you can do to get a little more of it!
The Stages of Sleep
Your body does amazing things while you’re snuggled up. Scientists have determined there are four stages of sleep, with each cycle lasting about 90 minutes. Theoretically, we should be getting around 7.5-8 hours of sleep per night, or roughly five cycles.
- Stage One: During this stage you are easily woken up, your eyes move back and forth, and your muscles begin to relax. You may even have some muscle twitching during this stage.
- Stage Two: Half of your sleep is spent in this stage. Your body temperature begins to drop, and your brain waves are (mostly) slower. Your heart rate and blood pressure also slow down and regulate. This gives your cardiovascular system a much-needed break.
- Stage Three: We spend about 20% of the night in this deep sleep stage. This stage of sleep gives us that “well-rested” feeling and is the hardest to wake up from. During this time of restorative sleep, our brain waves are slow, high-amplitude waves. Our blood pressure drops, our breathing slows down, blood flow moves to the muscles and tissues that need repair, and hormones such as the human growth hormone are released.
- REM (Rapid Eye Movement) Sleep: Researchers call this stage “paradoxical sleep.” Your body is asleep, but your brain looks like it is still awake. Usually, your most vivid dreams take place during REM. The first round of REM sleep is the shortest but gets longer throughout each sleep cycle. We spend about 25% of our night in REM.
Unexpected Health Benefits of More Sleep
Aside from feeling refreshed and aware, there are some startling health benefits to catching more zzz’s every night.
- A Better Sex Life: There is evidence to support that men who do not get enough sleep are associated with lower testosterone levels, which can decrease libido. As far as research into women’s libidos? A poll conducted by the National Sleep Foundation said 26% say their sex lives suffer because they are “too tired.”
- Better Control Over Your Weight: This is a two-fold issue. For one, if you are too tired, you may be less likely to have the energy to exercise or cook healthier meals. But there is a physiological aspect as well. While we sleep, leptin — the hormone that makes you feel full — is released. When you don’t get enough sleep, your leptin levels drop. This can cause you to feel hungrier throughout the day, and lead to high-fat and high-calorie food cravings.
- Better All-Around Health: Not only can getting enough rest boost your immune system and help fight illnesses like the common cold, sleep can help fight such issues as heart disease, heart attacks, diabetes, and even obesity. (One study even concluded that after only four days of disturbed sleep patterns in young and healthy adults, some had blood glucose levels that qualified as pre-diabetic!) Sleep alone won’t keep you disease free. But, it will give your body and your immune system time to recover and strengthen.
- Better Brain Power: While we sleep, our brains consolidate our memories from the day. Without enough sleep, those memories might not be stored correctly, and subsequently, be lost. Research also suggests that grabbing a quick nap during the day can help your brain be more effective, productive, and efficient.
How Do We Actually Get More Sleep?
So we know that getting more sleep can help us lead healthier lives. But, how do we train ourselves to actually sleep more? It’s easier (and more relaxing) than you think!
- Start A Sleep Diary: Writing down how you sleep and what wakes you up may help you determine patterns or issues. It is also helpful if you need to see a sleep specialist in the future.
- Perfect A Night Time Routine: Around the same time each evening, begin your “wind down” process. For some it’s reading, or your self-care routine. An efficient way to train your body to be ready for bed is doing the same routine at roughly the same time every night. Once you start your process, your body will begin to do the rest.
- Put The Electronics Away. Really.: You may think catching up on the news will put your curious mind at ease, but you’re actually giving your brain more stimulus that keeps you up longer. The additional information keeps your brain active and the particular type of light that emanates from these devices is activating the brain, disrupting your circadian rhythm. Try to stay away from devices for at least 30 minutes before bed. You can do it!
- Your Bedroom Is (Mostly) For Sleeping: If you find yourself tossing and turning, go to a different room and do something relaxing. Over time, your body will begin to associate your bed with sleeping.
- Exercise: Any amount of additional exercise (but especially vigorous exercise) will do wonders for your sleep patterns. Try avoiding exercising two hours before your bedtime routine begins.
- Get Comfy: Your mattress should be changed every 9-10 years. An unsupportive mattress can lead to nighttime discomfort and irritability. Change your pillows every 4-5 years and clean bedding every 1-2 weeks.
