Most of us are familiar with occasional sleep disturbances. But if we get too little sleep permanently, this can be massively detrimental to our health. These can be the consequences of a lack of sleep.
How much sleep we need to be fit and productive is very individual. For some people, six hours is enough, while others need nine to ten hours of sleep. For most of us, however, seven to eight hours is optimal to regenerate completely.
We probably all know how drained of energy and tired we feel when we've had a bad night's sleep or even a couple of nights. So it shouldn't surprise us what the health consequences can be if we don't get enough sleep over a long period.
When you don't get enough sleep, your body reacts in the following ways:
1. you become more sensitive
We react more acutely to sensory cues when we don't get enough sleep. This means we can no longer tell the difference between important and insignificant inputs. Loud noises, such as signal tones, might exacerbate our stress levels. This is analogous to the behavior of schizophrenic patients, whose brains have trouble distinguishing between significant and unimportant information.
2. your level of concentration drops
However, if we don't get enough sleep, it has far more negative effects on our brain. Concentration problems and forgetfulness are common side effects of its inability to renew properly. During the deep sleep phases, we store our memories, including all we learned that day. It has a negative influence on our brain's performance if we don't get enough of it if the phases are too short. When we don't get enough sleep, we're more likely to make grammatical errors and lose words.
3. you may gain weight
While we sleep, our body releases satiety hormones like leptin. If it didn't, we'd probably wake up hungry at night. This is because nighttime is the longest part of the day that we go without food. When we don't sleep, our body doesn't release these satiating substances - instead, it produces more appetite-stimulating hormones like ghrelin. The result: we feel more hungry.
When we haven't slept much, our body primarily craves foods that are high in fat and carbohydrates. Maybe you know it too: the typical hangover craving for fast food... Because these foods provide us with energy very quickly - but it only lasts for a short time, so we quickly get hungry again. So lack of sleep can lead to weight gain and thus increase the risk of health-threatening obesity.
.4. The skin ages more quickly
When we don't get enough sleep, our bodies produce stress hormones like cortisol. As a result, our skin's structure is harmed. It thins out, loses its suppleness, and dries out. Premature skin aging and wrinkles are a result of this.
5. You're at a higher risk of contracting ailments.
We raise our risk of several ailments when we sleep too little. When we don't get enough sleep, our pulse quickens and our body temperature drops. Our immune system is weakened as a result of this. This increases the risk of cardiovascular disorders such as arteriosclerosis, a heart attack, or a stroke, among other things. A meta-analysis of numerous studies demonstrates this.
High blood pressure and a slowing in the breakdown of blood sugar are two other possible health concerns. Too little sleep, on the other hand, not only affects the body but also raises the risk of mental diseases like depression.
