Did you know that staying awake through the night can be as difficult as trying to stop your heart from beating? This might seem like an odd statement, but according to recent research, it’s not far-fetched. When we’re not fully aware of our surroundings, and when we’re asleep, our brains continue to function normally. However, after a night of sleep, our brain waves slow down and we resume breathing in a regular pattern. 


As a result, when we wake up the following day, we’re more or less directionless; we have trouble recalling where we are and what’s going on. This is called “sleep inertia” (also known as “latent clock defect”). It happens to everyone who sleeps late the next day. The earlier you learn about this phenomenon, the easier it will be to avoid it in the future. 





### What can Late Sleep Do To Your Health?


If you’re not fully awake when you go to sleep, your brain waves slow down and you start to oxygenate the blood coming into your brain. This is good, as it helps your brain stay more vibrant and alert during the day. However, when we sleep, our brain waves slow down even more, and our blood flow to it is greatly reduced. 

This means your brain doesn’t get as much oxygen and nutrients while you sleep, and as a result, it’s “reorganizing” itself to prepare for the next day. As a result of this, there are changes in your brain the next day; you may not be as aware or “on” during the day, and you may feel groggy when you awake.


Staying up late at night can have a variety of negative health effects, some of which I will be  Listing below.

It’s important to note that these effects can develop after a single night of late sleeping and don’t mean you’re “all tarted up” for the next day. 

- Increased Risk of Dementia and Schizophrenia: A study looking at the correlation between insomnia and dementia conducted by the Crea Institute in Ireland found that the risk of developing both is significantly higher among those who sleep less than the recommended 8 hours. 

- Decreased Immune Function:  It’s been proven that a poor night’s sleep can lower your immune function and make you more likely to fall ill in the days and months that follow.


- Weight Gain: Staying up late can cause you to gain weight if you don’t get enough sleep; a study found that those who slept for seven hours or less gained weight at a rate that was three times greater than those who did sleep as normal.

As mentioned above, staying awake through the night isn’t good for your health in general. However, there are a few symptoms that may indicate you’re experiencing late sleeping.


 Most of them are similar to the ones mentioned above, but they’re specific to late sleeping: 

- Waking Up Early: After you’ve reached an adequate sleep schedule, you may begin waking up early; this is particularly common during rapid growth periods like adolescence and pregnancy. 

- Having Trouble Sleeping:  If you’re having trouble sleeping, you might experience sleep-related anxiety, depression or insomnia. Additionally, if you’re a teenager or an older adult, you may be sleeping late because of another health condition.


“Don’t put all the blame on sleep, there are a lot of things that can affect a person’s ability to sleep 

Having a stressful day, diet, etc. can all prevent us from getting enough sleep. If you’re experiencing late sleeping, here are a few ways you can try to fix the problem: 

- Limit caffeine and alcohol intake early in the morning. 

- Limit how much information you watch and how late you stay up. 

- Keep a journal (even if you don’t think you need to). It’s proven to improve sleep. 

- Find a way to wind down after a long day (even if you have to do it when you’re sleepy).

- Drink a tea or coffee (or caffe latte) base beverage. This will help your body relax while it sleeps.

Whether you choose to stay up late or not, there are certain health risks that come with it. Many of these risks can be avoided with a few adjustments to your routine. For example, if you’re an early riser, you can try waking up twenty minutes earlier every day. By doing this, you’ll be less likely to stay up late and cause yourself more trouble in the morning. 

As mentioned above, late sleeping is just as harmful to your health as early sleeping. If you’re not getting enough sleep, it can have a negative impact on your health and well-being. Late sleeping is one of the most obvious signs that you’re not getting enough sleep. 

To avoid late sleeping, researchers recommend keeping a sleep journal just like I have mentioned earlier this will help you better understand how you sleep and how your body responds to different sleep schedules. Furthermore, it’s important to remember that late sleeping is a risk factor for many diseases and health conditions. It’s important to do your best to avoid it.
