What is the video all about? Choose two statements that refer to the main ideas of the video.

1. Monitoring sleep with tracking devices like wearable technology significantly improves sleep quality according to experts.

2. Dr. Colleen highlights feeling rested during the day and uninterrupted sleep as indicators of good sleep.

3. The belief that only seven to eight hours of sleep guarantees good health oversimplifies the complexity of individual sleep needs.

4. Doomsday messaging is the best way to send the message to people who have trouble sleeping.

The first flaw is that it's not completely accurate. Seven to eight hours of sleep, while recommended for adults, is just an average. And while messages have to be for health communication to the public, sometimes important nuances get lost. So yes, it's true that not getting enough sleep in the long term is health problems like cardiovascular disease, diabetes, and depression. But on seven to eight hours ignores the fact that there's a range of sleep that people need. The duration of a good night's sleep can be different for different people. Some adults need eight but some are just fine on six. The second flaw with this kind of is that it can be couterproductive, especially for people who do have trouble sleeping. For instance, in 2019, it was estimated that 21 percent of adults in the US were wearing sleep . And that number is probably growing. And I get it. It's fascinating to see how much sleep you've gotten each night and to know what part of your night was spend in or dreaming. But having all that sleep data is causing some people to become it, so much so that it's leading to a condition some call orthosomnia: a preoccupation with the to achieve perfect sleep. And this condition, ironically, is causing more sleep problems.
