When someone’s asleep, it can look like they are turned “off” and not doing anything at all. But, that’s not true. Your brain and body are active and doing important things while you sleep, like organizing nerve cells, regulating hormones, repairing cells and clearing out toxins.
That’s why babies need 14 to 17 hours of sleep per day for the first three months of their lives – newborns are asleep way more than they are awake. Most school-aged kids need about 8 to 10 hours of sleep. Teens can aim for nine hours, which is what some adults need too. But seven or eight hours is enough for other grownups.
It’s important to get not only enough sleep but also good-quality sleep. And you should try to sleep on a regular schedule by going to sleep and waking up around the same time each day – even on weekends.
If, like many people, you struggle with getting enough sleep, there are some tricks to help you get good sleep on a regular basis. You may find it helpful to set an ideal sleep schedule and try to stick to it each day. You can set alarms to help remind you when it’s time to go to bed.
Use a wind-down routine for an hour before bedtime, to focus on keeping things relaxed and positive. You could include dimming lights, reading a fun book, and talking about the best parts of your day or just thinking about the day’s highlights. Try to avoid scary movies or books and getting into arguments just before bedtime.
In the morning, think of something you are looking forward to that day and let the Sun or bright lights into your room to let your brain know it is time to be alert.
You’ll know your sleep habits are working when you do not feel sleepy throughout the day and you wake up most days feeling refreshed. Just like being physically fit and eating a balanced diet, regularly getting a good night’s sleep is a behavior that takes practice and can pay off for a lifetime.
