What Happens When You Don’t Sleep For Days

If you're like most people, you need at least seven to eight hours of sleep per night to function at your best. But what happens when you don't get the sleep you need? That's a question that many people are beginning to ask, as chronic sleep deprivation has become increasingly common in today's society. It is estimated that 30% of adults are affected and 66% of adolescents are sleep deprived on a regular basis in the United States. This isn't merely a minor annoyance. 

Sleep is one of the most important aspects of our lives. It's crucial for our health, our moods, and our productivity.  Staying awake can be dangerous to our health. When we don't get enough sleep, our learning memory and reaction time suffer. Sleep deprivation has been linked to diabetes and obesity, as well as inflammation, hallucinations, and high blood pressure.

Sleep Deprivation

The majority of people have experienced sleep deprivation at some point in their lives. While an occasional lack of sleep is not a huge concern, the effects of chronic sleep deprivation can be severe and long-lasting. Sleep deprivation can even result in death in some extreme cases.

What happens when you don't get enough sleep?

Getting enough sleep is essential for a healthy life. Unfortunately, not everyone gets the recommended eight hours of sleep each night. In fact, many people struggle to get the sleep they need, leading to various health problems. 

According to Matthew Walker, Professor of Neuroscience and Psychology at the University of California and the author of the book - 'Why we sleep?', lack of sleep results in multiple health issues. Here are some of the health issues  that can be caused when you don't get enough sleep. 

1. Memory loss

We all know that not getting enough sleep makes it difficult for your brain to form new memories. So it's almost as though without sleep most of the memory cells in the brain shut down and you can't commit new experiences to memory.

Sleep, according to researchers, is crucial to the process of consolidating what we learn in the brain. To put it another way, we require adequate rest in order to retain new knowledge and commit it to memory.

2. Increased toxins in brain tissues

A lack of sleep will lead to an increased development of a toxic protein in the brain called beta-amyloid and which is associated with Alzheimer's disease. 

It is during deep sleep at night, when the cleaning system within the brain activates itself to wash away this toxic protein. So, if you're not getting enough sleep each and every night, more toxic protein will build which would then increase the risk of going on to develop dementia in later life.

3. Affects your reproductive health

Men, who are sleeping, just five to six hours at night, have a low level of testosterone, which a person who is aged more than 10 years to them would have. So lack of sleep will age you faster almost a decade in terms of that aspect of vitality and wellness. This has a direct impact on sex hormones.

According to recent research, in men, sex hormone levels were reduced by as much as 10% to 15% when they slept for 5 hours or less. They also indicated that with each night of disrupted sleep, their overall mood and vitality deteriorated.

4. Reduced immunity and increased risk of Cancer

Lack of sleep also impacts your immune system. So after just one night of four to five hours of sleep, there is a 70% reduction in critical anti-cancer immune cells called, natural killer cells. And that's the reason that short sleep duration, increases your risk for developing numerous forms of cancer. And that list currently includes Bowel cancer, Prostate cancer, and Breast cancer.

In fact, the relationship between a lack of sleep and cancer has become so strong that the World Health Organization recently declared any sort of midnight shift work to be a potential carcinogen. So in other words jobs that may induce cancer because of the disruption of your sleep cycle.

5. Impacts your cardiovascular system

Lack of sleep impacts your cardiovascular system because it is during deep sleep at night that you receive this most wonderful form of effective blood pressure medication which makes your heart rate drop and your blood pressure go down.

If you don't get enough sleep, your cardiovascular system doesn't get a chance to reset, and your blood pressure rises. If you're getting less than six hours of sleep, there is a 200% increased risk of having a fatal heart attack or a stroke in your lifetime. 

In addition, lack of sleep increases your chances of getting diabetes. You would be prone to effects of diabetes, like insulin imbalance and various other skin conditions.

6. Obesity

According to losing sleep causes the body to experience a hormonal imbalance that encourages weight gain due to  overeating. The hormones leptin and ghrelin control hunger, and then you don't get enough sleep, your body produces less of these hormones, which makes you feel more hungry.

Lack of sleep is connected to low levels of growth hormone and high levels of cortisol, both of whom have been linked to weight gain. Additionally, a lack of sleep might affect how your body processes food.

Unfortunately, changes at the chemical level are not the only way that sleep loss affects weight. It has been demonstrated that those who get less sleep are more likely to choose high-calorie foods. Late-night calorie consumption raises the possibility of weight gain. Adults who don't get enough sleep exercise less than those who do, presumably because sleep deprivation makes people tired and sleepy during the day.

7. Fatigue and irritability

The most immediate and noticeable effect of sleep deprivation is that you'll feel tired, groggy, and easily irritated. Sleep is essential for the body to repair and regenerate itself, and it plays a crucial role in maintaining a strong immune system. When you don't get enough sleep, your immune system may not function as well, making you more susceptible to illnesses and infections.

8. High blood pressure 

Not getting enough sleep can have a significant impact on blood pressure. Several studies have found a link between sleep deprivation and higher blood pressure levels. How? Lack of sleep can cause the body to produce more stress hormones, such as cortisol and adrenaline. These hormones can cause an increase in heart rate and blood pressure. 

The body's circadian rhythm, which is the internal clock that regulates many of our bodily functions, including blood pressure, can be disrupted by lack of sleep. This disruption can lead to higher blood pressure levels.

9. Weakened immune system

Sleep is important for your immune system, and if you don't get enough of it, you may be more susceptible to infections and illnesses.

During sleep, the body produces cytokines, which are proteins that help the immune system fight off infections and inflammation. Lack of sleep can reduce the production of these cytokines, making it more difficult for the body to fight off infections.

White blood cells, which are a key component of the immune system, are also produced during sleep. Lack of sleep can reduce the number of white blood cells, making the body more susceptible to infections.

10. Cognitive impairment

Your ability to think, reason, and make decisions can become severely impaired when you don't get enough sleep. You may experience problems with concentration, memory, and attention.

Sleep plays a crucial role in consolidating memories and learning new information. Lack of sleep can impair memory consolidation, making it more difficult to remember information. Sleep deprivation can slow down reaction time, making it more difficult to react quickly to stimuli and therefore leading to poor judgement.

How much sleep is necessary?

According to the National Sleep Foundation, healthy adults require between 7 and 9 hours of sleep per night.Babies, young children, and teenagers require considerably more sleep in order to develop and grow. People above the age of 65 should obtain 7 to 8 hours of sleep per night as well.

The amount of sleep people need can vary based on various factors such as age, lifestyle, and health status. However, here are some general facts about night sleeping patterns of people:

1. The quality of sleep is just as important as the quantity. The ideal sleep is one that allows you to go through all stages of sleep, including deep sleep and REM sleep.

2. It's normal to wake up briefly during the night, but if you wake up frequently or have trouble falling asleep, it could be a sign of a sleep disorder such as insomnia.

3. Many people experience changes in their sleep patterns as they age. Older adults tend to have a harder time falling asleep and staying asleep, and they may also wake up earlier in the morning.

4. Sleep needs can vary based on lifestyle factors such as work schedule and physical activity. For example, people who work night shifts may need to adjust their sleep schedule to get the recommended amount of sleep.

5. Sleep is crucial for overall health and well-being. Chronic sleep deprivation has been linked to a range of health problems, including obesity, diabetes, and cardiovascular disease.

6. While everyone has a different sleep pattern, maintaining a consistent sleep schedule is essential for quality sleep. This means going to bed and waking up at the same time every day, even on weekends.

How long can we actually last without sleep before we start to see a decline in our brain functions and impairments within our body?

The answer appears to be approximately 16 hours of awake time. When you've been awake for more than 16 hours, your mental and physiological health begins to deteriorate.

Your mental capability is so diminished after 19 or 20 hours of wakefulness that you behave like someone who is drunk.

Good night sleep

What you can do to improve your sleep at night?

There are few tips that can help you get better sleep at night. Let us try to follow these.

1. Maintain regularity in sleep time

Try to stick to a schedule. And if there's one thing you take away from this - it's that you should go to bed and wake up at the same time. 

It doesn't matter even if you've had a horrible night's sleep, whether it's weekday or weekend, wake up at the same time every day and reset.

2. Induce release of hormone - melatonin

We require darkness in the evening to facilitate the release of melatonin, a hormone that aids in the proper timing of our sleep. So, one hour before bed, attempt to dim 50% of the lights in your house. 

Stay away from devices, especially LED screens, which generate blue light, which inhibit melatonin production.

Even if it's dark and you want to sleep, blue light-emitting devices trick your brain into believing it's still daytime.

3. Maintain optimum room temperature

Many of us have a bedroom that has a higher temperature. As a result, the ideal temperature is around 68 degrees Fahrenheit (18 degrees Celsius). 

The reason for this is that in order to fall asleep, our brain and body must lower their core temperature by roughly 2 to 3 degrees Fahrenheit.

That's why it's usually simpler to fall asleep in a room that's cold than in one that's warm. As a result, sleeping in a colder room helps your brain and body adjust to the proper temperature for a good night's sleep.

4. Avoid alcohol and caffeine

When it comes to sleeping, alcohol may be the most misunderstood drug. It is believed that it aids in sleeping. That is not correct; alcohol belongs to the sedative drug class, and what you are doing is just knocking out your brain. 

You aren't allowing it to go asleep naturally. Your sleep will be fragmented as a result of the alcohol, and you will wake up frequently throughout the night.

Alcohol can also prevent you from having a dream or going into rapid eye movement sleep.

Caffeine is another issue. Caffeine, as we all know, may keep us alert. Few people realize that even when you can have a cup of coffee after dinner and fall asleep, the depth of the sleep you have when caffeine is present in your brain isn't as deep as when you don't have that cup of coffee after dinner.

As a result, you wake up the next morning feeling tired and unrefreshed, and you have no recollection of waking up or having difficulty going asleep. But now you're reaching for three cups of coffee in the morning, and you're stuck in this vicious cycle of dependency on caffeine.

5. Avoid staying awake in bed

Don't stay in bed awake if you haven't fallen asleep in 20 minutes or if you've woken up and are having trouble falling back asleep. 

The reason for this is because your brain quickly learns to associate your bed with being the place where you're awake rather than being the place where you sleep.

So the advice is to get up, walk to another room, and read a book in dim light. Return to bed just when you feel drowsy.

And in this way, you can truly retrain your brain to understand the relationship between your bedroom and the place where you sleep rather than the place where you are awake.

It should be emphasized that some people are opposed to this concept.

6. Exercise

If you're looking for an easy and convenient way to get your recommended amount of sleep each night, exercise may be the answer for you! Not only does exercise improve your general mood, but it can also help to improve your sleep habits. In fact, according to one study, people who exercised had a greater chance of sleeping better than those who didn't exercise. So if you're looking for a way to improve your overall health and wellbeing, exercise may be the best solution for you!

7. Try meditation or yoga during the day

You can also try meditation. Clinical research has shown that meditation can help patients relax their bodies, calm down, and fall asleep more quickly.

Exercise such as yoga boosts your metabolism, raises your body temperature, and boosts hormones like cortisol. If you exercise in the morning or afternoon, this isn't a problem, but if you exercise too close to bedtime, it can disrupt your sleep.

Workouts that are moderate to vigorous should be completed at least three hours before bedtime. Start your workouts earlier if you're still having difficulties sleeping. In the evening, low-impact workouts like moderate stretching or yoga can help you sleep better.

Better Sleep

Final Words

We can all agree that sleep is the key to a healthy body and mind. Yet, we often prioritize our work and social life over getting enough shut-eye. That’s why it’s so important to be aware of the health risks that come with not sleeping well. The health issues due to lack of not having enough sleep can make you put your health into risk. 

Not getting enough sleep for days can have a significant impact on your body and mind, and the consequences can become more severe the longer you go without sleep. Sleep deprivation can cause fatigue, irritability, cognitive impairment, hallucinations, and an increased risk of accidents and mental health problems. Additionally, chronic sleep deprivation can weaken the immune system and contribute to physical health problems. Therefore, it's crucial to prioritize getting enough sleep each night to avoid these negative effects on your health and well-being. 

The tips we shared above can help you. Inculcate and practice them. Start making some small changes today. Even then, if you're struggling with sleep, it's a good idea to talk to a healthcare provider who can offer personalized advice and support. Overall, getting enough quality sleep is essential for good health and a high quality of life.
