A major part of your health depends on your sleep. While you may delay your sleep or skip it to do other tasks, your body keeps the score. You may be slowly pushing yourself into not just physical health issues, but also mental health issues. While sleep may seem like an easy thing, you only need enough time for there are many aspects of it that could reveal whether you are sleeping well or not. In a recent post, Dr Christopher J Allen, MD, a US board-certified sleep doctor, revealed 10 important sleep facts that one must know. Sleep Advice You Need For Proper Rest In the video titled, “Advice I’d give you as a sleep doctor for a decade – If I wasn’t afraid of hurting your feelings” he gave the below mentioned advice. Snoozing Doesn't Help Hitting the snooze button actually confuses your brain. It starts a new sleep cycle that you immediately interrupt. This guarantees you will feel more groggy and tired all morning, not rested. Just get up when the alarm first rings. Late-Night Energy Isn't Natural Feeling "wired" late at night isn't natural energy. It usually means you've had too much stimulation, you're dehydrated, and you're stuck in a constant stress cycle. Your body is running on high alert, not true fuel. Instant Sleep Isn't Healthy If you fall asleep the second your head hits the pillow, you don't have great sleep; you have a problem. It's a clear sign of severe exhaustion or a major sleep debt built up from missing sleep over time. You Need Recovery, Not Stimulants Your constant low energy can't be fixed by simply drinking more caffeine. Your real issue is a lack of proper recovery. You need more REM sleep—the deep, restorative kind—to truly solve your energy problem. Midnight Waking Is Stress-Related Waking up sharply at 3 AM is not random bad luck. It often happens because your stress hormones, called cortisol, start pumping during the night. Your body is on high alert, starting its "night shift" while you should be resting. Scrolling Isn't Relaxing You think you're relaxing when you scroll through your phone, but your nervous system disagrees. The bright screen and constant stimulation signal danger to your brain, putting you into survival mode instead of calming you down. Weekend Catch-Up Doesn't Work Trying to "catch up" on sleep during the weekend doesn't fix your sleep debt. It simply throws off your body's internal clock (circadian rhythm). This actually makes it much harder to wake up and start your week on Monday. You Can't 'Get Used To' 5 Hours Science shows that believing you are "used to" only five hours of sleep is dangerous. Your body is actually quietly suffering damage and breaking down. You need more sleep to avoid long-term health risks. Tiredness Starts Before Bed Waking up feeling completely exhausted isn't usually your mattress's fault. It’s often connected to your stress mindset, the food you eat, and those sneaky stress hormone spikes that happen while you should be deeply sleeping. Most Important Factor For Sleep The health expert ended the post by explaining your body can't truly heal and recover if you keep it in the same environment and under the same stress that makes you feel run down. Your bedroom and your nightly routine are actually a direct reflection of your entire lifestyle. The core scientific truth is that your body isn't being lazy, it is genuinely exhausted, and your brain isn't broken, it's just begging for the safety and security that comes from good, proper rest.
