How was your sleep last night? Sleep is important for health. How can we have healthy sleep? Take a look at some advice.
Wake up naturally
Waking up to a ringing alarm is never fun. Studies show that when you get shocked by the alarm, your breathing will go up, your heart will have more beats and your blood pressure will rise.
"This is a very unhappy way to start the day," sleep scientist Whitney Roban said. "You'll feel worse if you go back to sleep a few more minutes. It's important to follow your body's natural sleep-wake cycle (循环)."
So what should we do? Try to use an alarm with softer and lower sounds. Or leave a crack (缝隙) in the curtains(窗帘) – the rising sun will wake you up.
Sleep early and get up early
Some young people may go to bed late and get up late, such as sleeping from 2 am to 10 am. They think as long as they have eight hours of sleep, everything will be fine.
But in fact, our bodies can tell time. They use light and temperature to do so. If we wake up too late, our bodies might feel stuck between sleep and being awake. That's why sometimes we feel even more tired after oversleeping.
