Sleep consumes one third of our lives. Most people need a minimum of eight hours sleep each night for normal mind and body function. But how many hours sleep did you get last night? Changers in our lifestyles and modern technology have tended to reduce the amount and quality of the sleep we get. Sleep deprivation is becoming a major issue today but many people don’t recognize that it is a major health problem. This essay will show the consequences of not getting enough sleep.

First, not getting enough sleep affects people’s minds in negative ways. First of all, people can’t appropriately cope with emotions. For instance, people will more easily get ratty and depressed. Then, sleep deprivation will worsen people’s memory. A good and long sleep can boost memory and creativity, so if you don’t sleep enough, your brain will stay inactive and forget lots of things. Clearly, insufficient sleep will make people become more forgetful and cranky.

Second, not getting enough sleep affects people’s health and body function. Firstly, the most common effect is sleepiness throughout the day. This may cause some bad problems. For example, sleepy workers make more mistakes at work which can be dangerous or cost lots of money. Next, it increases the risk of getting sick. Because of lack of sleep, people’s resistance becomes lower. Therefore people are prone to diseases such as cold and flu. Thirdly, people’s reactions will be more slowly. People can’t immediately protect themselves when some emergencies happen, such as a fire, an earthquake. In short, humans need a certain amount of sleep to let health and body function well.

In conclusion, people require at least eight hours of sleep every night. Without enough sleep it may cause many negative influences. Therefore it is significant to get sufficient sleep to keep physiology and mentality healthy.
