If you need an alarm clock to wake you up every morning, or even if the alarm clock does not work for you and often oversleep – you are definitely not getting enough sleep. How much sleep do you need to get to be considered adequate? There is really no standard answer to this. Sleep time is related to many factors, including genetics, gender, age, etc. And the sleep time of each person is not fixed, and will change with age or environmental changes. Sleep is also a matter of timing and location. In addition to a comfortable bed and a suitable room, when to sleep is also important. Some studies have shown that it is good to get enough sleep for six hours immediately before the body temperature reaches its lowest point. Since human body temperature reaches its minimum around six o’clock in the morning, it would seem that one should be in bed by 12 o’clock every night. Although there is much debate on how much sleep is needed, there is no dispute that lack of sleep is bad for your health. Sleep deprivation can lead to higher blood pressure, weight gain and inflammatory responses, increasing the risk of heart disease and diabetes. In addition, as most people have probably experienced, sleep deprivation can make people depressed, grumpy, slow-thinking and unresponsive. It’s safe to say that lack of sleep is really the enemy of our physical and mental health. However, we always seem to find more important things than sleep. The endless overtime, the heavy and stressful research, the movies that make you itch to keep watching, the games that make you want to keep playing …… In many people’s lives, these things are prioritized over sleep. When you sacrifice sleep and do many other things you think are meaningful, only to end up with an increasingly sluggish brain, a gradually deteriorating body, and illnesses that visit from time to time, you realize that all those things you traded for sleep are just clouds. How can you determine how much sleep you need? An alarm clock is enough. Try going to bed a quarter of an hour earlier, do you still need an alarm clock the next day? If so, go to bed another quarter of an hour earlier until you no longer need the alarm clock and sleep until you wake up. That way you know how much sleep you need. Also, are you dependent on coffee? Do you have to drink several cups a day to stay awake and go to work? If so, you’re probably not getting enough sleep. However, if you are not one of those extreme long sleepers who sleep more than seven and a half hours a day, but still wake up feeling dizzy, it is likely that you did not sleep deeply enough and your brain is not getting enough rest. However, it is also possible that sleep apnea has crept up on you. The typical symptom of sleep apnea is snoring. If such a condition occurs, you may need to see a doctor.
