Quiz: What Is Your Chronotype?

Learn why you have the sleep problems you do and how to solve them with this quiz created by Dr. Michael Breus.

You chronotype, or biological clock, affects your sleeping habits.

A chronotype is your own personal biological clock that controls your body's rhythms. It's the reason you are grumpier in the morning or focus better later in the day. This genetic biological clock affects much more than your waking and sleeping patterns. It affects when you should eat; when the best time for coffee is; and when you should socialize, work and exercise, among other things. Find out if your chronotype is a lion, dolphin, bear, or wolf, and how these types impact your sleep and habits.

What to Do When Your Partner Sleep Talks & You Really Need Some Rest

Sleep talking is both common and almost always harmless... to the person doing the talking.

Q: My partner has started talking in his sleep — a lot. Is it a sign of anxiety or something physically wrong? It's ruining my sleep and it can't be good for his sleep. How can I help him stop?

A: Sleep talking is both common and almost always harmless... to the person doing the talking. It may be expressed in incoherent mumbles or be clear as a bell, and it can be related to dreams or simply come from thoughts floating through a sleeping brain. The talkers usually have no idea it's going on and their sleep is not disturbed by it. A study in the journal Sleep Medicine found that around 66% of people have experienced sleep talking —but it isn't something that is frequent or persistent.

Is Sleep Talking Bad for My Health?

Sleep talking is not considered a health risk, but there are sleep disturbances that are linked to long-term health problems, such as mood disorders, cognition problems, heart disease, diabetes and even colorectal cancer. Sleep talking is also distinct from other conditions that trigger vocalization during sleep, such as catathrenia, a breathing disorder that causes audible groaning, and REM sleep behavior disorder (RBD), in which a person physically acts out a dream. Those conditions should be treated by a sleep specialist.
