Here’s What Happens to Your Body When You Get Less Than Seven Hours of Sleep

Every day, millions of people around the world experience the effects of sleep deprivation. Whether it’s caused by a demanding job, a hectic lifestyle, or an underlying medical condition, not getting enough rest can have serious consequences for your health. Let’s take a look at what happens to your body when you get less than seven hours of sleep per night.

Cognitive Decline

The most obvious consequence of sleep deprivation is cognitive decline. When you don’t get enough rest, your concentration and focus suffer, making it difficult to concentrate and make decisions. This can lead to problems with work or school performance and can even affect relationships. Memory is also affected by lack of sleep. Studies have found that individuals who are chronically sleep-deprived have difficulty forming new memories and recalling old ones.

Physical Health Issues

Sleep deprivation doesn’t just affect cognition, it also has an impact on physical health as well. Lack of rest increases the risk for certain chronic conditions such as heart disease, diabetes, obesity, hypertension, and stroke. It also weakens the immune system, making it more difficult for the body to fight off infections such as colds and flu. Additionally, studies have found that people who don’t get enough sleep are more likely to suffer from fatigue during the day and may be prone to accidents due to lack of alertness.

Emotional Well-Being

Finally, it’s important to note that lack of sleep can take a toll on emotional well-being as well. Studies have found that individuals who are chronically sleep-deprived are more likely to suffer from depression and anxiety than those who get adequate rest each night. Sleep deprivation not only affects mood but can also lead to irritability and difficulty managing stress levels during the day.


As we can see from this overview, getting less than seven hours of sleep per night can have far-reaching consequences for both physical and mental health. If you’re having trouble getting enough rest each night, it might be time to take steps towards improving your quality (and quantity) of your slumber. Your body will thank you in the long run.
