How much do you know about sleep disorders? Let's explore the biggest myths and truths about them:
- There is no any correlation of health problems and the amount and quality of an individual's sleep
False: Scientists found a direct correlation between insufficient/poor quality sleep and some diseases. These are diabetes, high blood pressure, and depression. Too much sleep can also result in lower growth hormone secretion that leads to obesity.
- Older people need less sleep
False: An adult person needs from 7 to 9 hours of sleep per day. While the sleep patterns can change during life, the amount of sleep we need do not change. The truth is that older people can sleep less at night because of frequent night walking, however they need the same amount of sleep as regular adults do.
- Snoring can be harmful
True: Besides being bothersome to other people, snoring can also be a sign of a sleep disorder, called sleep apnea. Sleep apnea is linked with diabetes and cardiovascular disease. Having sleep apnea, a person can remember walking up during the night very often because he feels lack of airflow or no airflow at all.
- Teens need more sleep than adults
True: Indeed, teenagers need from 8.5 to 9.5 hours of sleep every night. As it was mentioned above, the normal level for most adults is from 7 to 9 hours.
- Insomnia can be characterized only as a difficulty falling asleep
False: There is more than just one symptom that is associated with insomnia. Here are the main signs of it:
- Difficulty falling asleep
- Frequent awakenings
- Waking up too early without being able to get back to sleep
- Feeling tired and lethargic after waking up
- Feeling sleepy during the daytime means that a person doesn't get enough sleep
False: Although it is commonly known that daytime sleepiness usually occurs in situations when you didn’t get enough sleep last night, it can also happen after a good sleep. This condition can be resulted by a sleep disorder like sleep apnea or narcolepsy.
- The brain rests during sleep
False: The truth is that it is the human body, not brain, which rests during sleep. All this time the brain remains active, controls many body functions (like breathing during your sleep), and is recharged.
