Why You Need To Care About Sleep Deprivation

Introduction

Sleep is a biological imperative for a lot of organisms. Though much about sleep is shrouded in mystery, one thing is clear- it is very restorative and good for the body and the mind. A good night’s sleep can do wonders for tiredness, your lousy mood and help your body recover from a long day at work or school. Sleep is a finely regulated phenomenon- with the production of certain hormones and neurotransmitters that are made at specific times in the day. Melatonin is a very well known molecule that is produced by the pineal gland located deep in your forehead. It uses information from the eyes to check how much light is present and then synthesises melatonin accordingly. More is made at night in the absence of light, when compared to the day. This crucial hormone helps the brain synchronize its internal clock. Glycine is an amino acid that tells the brain to relax, along with GABA. When these molecules are not produced in the right amounts at the right time, you incur a sleep debt. Sleeping poorly can affect you systemically, so let’s look at 4 concerns in detail. 

How Does Sleep Deprivation Affect The Brain?

Pulling all nighters regularly can get you closer to that promotion sooner but it is bad for your brain in the long run. The brain is always active, even when you are asleep- some areas in fact begin to work only when you are in deep sleep. Sleep is necessary for you to form new memories and to help you sharpen your problem solving skills. If you don’t sleep enough, you won’t be able to focus on work and you may not be able to exercise your decision making skills that accurately either. You will also feel annoyed and take that frustration out on others-which means your social skills are also impaired. 

Can Sleep Deprivation Lead To Poor Immunity?

Yes, high levels of stress hormones can lead to greater chronic inflammation in the body. The immune system has to work overtime to take care of you in this case. This situation gets markedly worse when you don’t sleep enough. 

Can Sleep Deprivation Cause High Blood Pressure?

Dealing with sleepless nights can leave you feeling more stressed than usual. This means you will have way more cortisol than is necessary, which can increase blood pressure. If you are always stressed, then you will probably have to deal with hypertension in the future. 

How Does Sleep Deprivation Affect Metabolism?

Not sleeping at night can mean you will feel hungry at odd hours- more snackage than needed. Your blood glucose levels are not well regulated in such a scenario and this can lead to chronic inflammation. This is also how diabetes may begin. Changes in metabolism can cause the fat cells in your body to behave differently. You may have to deal with a dreaded ‘paunch’ too because your brain processes hunger cues more urgently. More of the ‘hunger’ hormone leptin is made and you don’t feel full as well, even if you have eaten properly. 

Conclusion

The lack of sleep and its impact on work performance has been well documented in many industries. For some. Loss of sleep is a genuine medical condition, in which case getting it treated immediately must be a priority. Some of you may have issues like sleep apnea, insomnia, eating disorders or may need to work at odd hours. All of this can contribute to massive changes in your daily routine. 

FAQs

1. What are the immediate effects of not getting enough sleep?
Your mood may be in the toilet, you can feel super tired and you may not be able to focus on work. Concentration may not be that great, so if you need to keep looking at minute details often, you may miss some. You will be a lot slower when you have to come up with solutions and you may not be able to exercise your decision making skills well. 

2. How does sleep deprivation affect brain function and memory?
You could forget more than before and you may not be able to process information like normal. Plus, being stressed about not getting enough sleep can ruin your mood for the day and make you feel pretty antisocial too. 

3. Can lack of sleep cause weight gain or affect metabolism?
Sleep deprivation can mess your hormones up big time, causing you to binge eat or snack at odd hours. Both of these factors need to be well within control and range for you to be able to have a decent metabolism and manage weight. 

4. Can lack of sleep contribute to serious conditions like stroke or dementia?
Dementia means to forget stuff and not sleeping enough can cause memories to not form properly, or even if they are present, you may not be able to retrieve them at the right time. Stroke risk is also higher in people who don’t sleep enough or sleep too much. So, sleeping just right needs to be on your agenda every night. 

5. What are the best ways to recover from sleep debt and improve sleep quality?
You should try to be super consistent about bedtime and wake up at the same time too every morning. You should try not to nap, use dim lights in the evening and eat well before sleeping, so you don’t stay up due to a full tummy. For melatonin to be produced, you need to get enough sunlight into your eyes, and try not to use your laptop or phone more than needed.
