How to use a fitness watch to monitor your sleep and heart rate

A fitness watch that monitors your heart rate can help you sleep better and stay healthy at night, according to a new study from Northwestern University.

The researchers used a smartphone app called SleepWatch that tracks sleep, sleep quality and your heart-rate.

It can be used to monitor the amount of sleep you get, how long you sleep, and how well you are sleeping, said the study’s senior author, Paul Wertheim, a professor of psychiatry at Northwestern University Feinberg School of Medicine.

The app has been downloaded more than 15 million times, and is now available for free on the App Store.

SleepWatch can use your sleep logs to give you a more personalized view of your sleep, Wertheimer said.

You can also use it to track your heart, which is also important for cardiovascular health, and track sleep stages, he said.

SleepWatch was designed to provide an accurate, up-to-date snapshot of sleep, but it can also help you monitor your heart and sleep patterns, Wierheim said.

The researchers tracked six men and three women for nine days.

The men and women had a baseline sleep and sleep quality of 7 hours a night.

Each person’s baseline sleep was taken at the beginning of the study and the last day of the follow-up.

The participants slept in the morning and had to stay up all night to record their sleep and wake up.

The sleep quality was measured by measuring the heart rate.

It was measured with a digital heart monitor, and then measured with an electrocardiogram (ECG).

The heart rate was then measured every hour for nine hours.

The results of the data collection were compared with the baseline data to determine if the two sleep patterns were different.

After analyzing the data, the researchers found that the men and the women who had the SleepWatch app slept less, slept better, and had less sleep disruptions than those who did not have the app, the study showed.

The men and men who had SleepWatch slept better than those without the app also had lower levels of stress and higher levels of sleep quality, the Sleep Watch app showed.

Sleep quality was lower for both men and for both women, but there was no significant difference between men and other men.

The women had less daytime sleep, too, the report showed.

The Sleep Watch report also showed that men had higher levels in the stress hormone cortisol, which helps to regulate sleep and stress, the scientists found.

The women who used SleepWatch also had more heart activity during the day, which suggests that sleep is linked to better health, Widerheim said in a news release.
