HOW TO GET MORE SLEEP

Many studies warn that not having enough sleep may lead to serious health problems, affecting our daily life, work and study. You’ve probably known this for long, yet you still don’t get a full night sleep due to an incredible work schedule. So what can you do to make more time for sleep, and get a better night’s rest overall?

• Invest in a better-quality mattress. If you’re sleeping on a years-old, worn-out mattress(床垫), it’s no wonder why you wake up feeling tired in the morning. 1. With a new mattress that’s better suited to your sleeping habits, you’ll get to sleep faster and stay asleep consistently.

• 2. There are many habits that can affect how much sleep you get, including how much caffeine you consume throughout the day (and when you consume it — even a few hours before bedtime can interfere with sleep), whether or not you physically exercise, and how long you spend staring at a digital screen before bed.

• Take a closer look at your schedule.3. In Western culture, there’s a lot of pressure to fill up our schedules to seem important and socially integrated, so your daily activities might have some faults or unnecessary tasks that can be skipped or delayed. 4.

Sleep is even more important than you probably realized, but it’s entirely within your power to reshape your sleeping habits for good. Make sleep your first priority, scheduling time for it the way you’d schedule a meeting, and work the rest of your schedule around it. 5.

A.Watch your habits.

B.Some habits contribute to a good night’s sleep.

C.Without enough sleep, you could take more risks in your life.

D.A new mattress can be a big investment, but it’s almost worth the money.

E.Draw a line between professional and personal time, and make sleep a higher priority.

F.If you feel like you’re too busy to sleep, consider taking a second look at your schedule.

G.In time, it will become the new routine, and you’ll improve your health and productivity.
