Experts explain that one of the first issues to consider is the number of hours of sleep recommended. First preventive action is to find out how rest is “sufficient”.
Recommended Sleep Hours: New Guidelines
The professor at Harvard University, Charles Czeisler conducted research along with other experts with intention to determine the recommended hours of sleep. They conducted different studies between 2004 and 2014. They have analyzed objective in order to determine how much rest was not enough to affect the health of people.
According to the different stages of development, scientists came to the following conclusion:
NEWBORN (0-3 months): 14 – 17 hours.
BABIES (4-11 months): 12 – 15 hours.
CHILDREN (1-2 years): 11 – 14 hours.
PRESCHOOL (3-5 years): 10 – 13 hours.
SCHOOL AGE (6-13 years): 9 – 11 hours.
TEENS (14-17) : 8 – 10 hours.
YOUTH (18-25 years): 7 – 9 hours.
ADULTS (26-64 years): 7 – 9 hours.
SENIORS (over 65 years): 7 – 8 hours.
Note: the hourly rates are approximate. Each person individually may present a certain variation in the number of hours of rest. It is important to highlight that any considerable decrease in the number of recommended hours of sleep can pose a health risk.
Main causes of sleep problems:
According to experts, there are 2 main factors that can trigger rest problems. The first is stress and the second is technology.
Stress: when you are under stress, your body starts releasing cortisol which also is known as the “stress hormone”. Elevated levels of cortisol prevent restful sleep and also interfere with feelings of well-being.
Technology: excessive use of technological devices prevents the brain to release the amount of melatonin needed. By staying in the dark, human body releases more melatonin. The cell phones, laptop or televisions are interrupting this process.
