Do we really need 8 hours of sleep?

Doctors all around are recommending teens to get 8 hours of sleep, but do we really need it? Some of us need 8+ hours of sleep, while others need 8 or less hours of sleep. It typically depends on if you feel tired or not after sleeping for 8 hours.

Personally, I operate best off 7 hours of sleep. It took me over 8 months to figure out my best sleep schedule. Off 8 hours of sleep or more, I am groggy beyond belief. But it depends on how your brain works. Some of us are too tired with 7 hours of sleep and perfectly fine with 8 hours.

The average person sleeps for roughly six and a half hours every night. Most of us do not need 8 hours of sleep, but some of us do. So why does our doctor recommend it to us? According to, 8 hours of sleep can reduce the risk of serious conditions such as diabetes, heart disease, and even death. So even though we wake up tired, it may be prolonging our life. When you sleep, your heart rate, breathing and other involuntary body functions slows when we sleep. Mainly because our heart does not need to be beating at 120 beats per minute (BPM) when we sleep because we are not doing much when we sleep.

Even though sleeping for 8 hours makes us feel tired, it may be helping us by protecting us from a severe illness that not many of us had a clue that sleep helps prevent.
