Experts have been really studying the effects of sleep – or lack of- on the human body in recent months. While we have known for decades that it's important to get a good sleep every night, new research has shown just how damaging poor sleep habits can be on the body. While circumstances such as age, pregnancy, and overall health might contribute to our sleep needs, as adults we need an average 7 to 9 hours of sleep each day. Without a proper sleep, we suffer mentally and physically. Here are some of the important reasons why we need adequate sleep.
Getting a proper sleep helps your body fight disease. There have been several studies on how sleep deprivation increases your risk of heart disease, diabetes, obesity and other life-threatening diseases and medical conditions. While several studies believe that it takes years of poor sleep to contract a disease, other studies have shown that the effects can start after as few as 4 days. The longer you go without adequate sleep, the higher your risk of developing many serious medical conditions.
People who are chronically tired tend to be more irritable than well-rested adults. Sleep deprivation has not only been linked to moodiness but also to poor stress management, depression, anxiety and increased emotional distress. People who are overtired are more likely to have sudden outbursts of anger as well as uncontrollable crying and laughing episodes.
Risk of Injury
Lack of sleep has been shown to be a primary contributing factor to many injuries at home, on the roadways and at work or school. When we're tired, we are not as aware of our surroundings or alert and tend to have difficulties paying attention to what we're doing. We also have slower reaction times and are more likely to fall asleep while performing other tasks. These factors contribute to higher risk of accidents that can range from mild to life-threatening.
This might come as a surprise to some but good sleep helps us manage our weight. First, it balances our hormone outputs such as Leptin which triggers our feeling being full. People who are overtired tend to feel hungry more often and are more likely to eat foods higher in sugars, caffeine, and other unhealthy ingredients to try to boost their energy levels. This increases calorie intake which can increase our weight.
Effect On Memory
People who lack proper sleep have a harder time remembering then well-rested individuals. Many studies have been done to show just how poor sleep patterns affect our memory. They have found that those who don't get enough sleep have a significantly more difficult time retaining information. This can have a major impact on our ability to learn. Because our ability to remember information is poor, it impairs our ability to learn, affecting our school, work, and home life.
The body needs adequate rest in order to function at it's optimal best. Poor sleep patterns can result in many physical, psychological and mental conditions that can have an immediate and long-term effects on our overall well-being. Healthy sleep patterns are important for good health.
