Thanks to the power of connected devices, Withings is able to provide a national health observatory accessible to the general public. Using real-time data, this tool allows us to track the prevalence of key risk factors linked to lifestyle: sedentary behavior, overweight and obesity, and high blood pressure.
The observatory invites you to discover exclusive data and information gathered from the Withings community. Which American states are most affected by sedentary behaviors or by overweight and obesity? Are all age groups affected? Check out the informative graphs and charts of the Withings health observatory to learn more about health behaviors and different lifestyles across the US.
Sleeping well is essential for our health and well-being. However, sleep duration shortening is a behavior that is becoming more and more widespread. The Centers for Disease Control and Prevention estimate that 35% of U.S. adults do not get enough sleep. Yet, repeated lack of sleep might have harmful effects on health: hypertension, obesity, decreased attention (increasing the probability of accidents at work or on the road), and depression, to mention only a few of them.
In this context, it is necessary to increase general awareness about this subject. To contribute to this objective, Withings has created a real-time observatory of the sleep of Americans.
Sleep is something that you spend one third of your life doing. It is a vital bodily function, like breathing or digestion. It plays an important role in learning, memorization and adaptability. It is also essential to your overall well-being.
We are all very different when it comes to sleep. Most people need 8 hours of sleep. But some people are "short sleepers" who only need 7 hours of sleep. On the other hand, some people are "long sleepers" who need at least 9 hours of sleep a night.
Additionally, sleep needs vary with age. The National Sleep Foundation recommends for example from 9 to 11 hours of sleep for children aged 6 to 13 years old, and from 7 to 9 hours of sleep for adults aged 18 to 64 years old. In Withings’ dashboards, we follow this classification. Therefore, adults repeatedly sleeping less than 7 hours per night are considered to be sleep deprived .For more details about the definitions we use, please visit our section on data protection policies and definitions used.
Analyze the latest figures for the prevalence of sleep deprivation in US states*. Select a state to see its detailed profile.
Sleep deprivation is associated with weight gain: a study shows that people lacking sleep are 35% more likely to experience a 5-kg weight gain, as compared with average-duration sleepers over 6 years1
Physical activity improves sleep: 150 minutes of exercise per week are enough to improve significantly the quality of sleep2
Lack of sleep is bad for the cardiovascular health: it is associated with a risk 1.45 higher of developing a coronary heart disease3, and 2.1 higher of developing an hypertension4
Sleep impacts greatly your mood: researchers found out that people subject to less than 5 hours of sleep during a week would declare to feel more stressed, angry and sad. Their mood would improve after 2 nights of normal sleep5
Experiencing difficulty to fall asleep is often the 1st sign of a depression. Studies estimate that people suffering from chronic insomnia are 5x more likely to develop a depression, and 20x more likely to develop an anxiety disorder6
The truth about beauty sleep: a study reveals that the physical appearance after a night of good sleep, compared to after a short-sleep night, is considered more attractive by others7
Sleep apnea is a disorder that goes often undiagnosed, characterized by repeated interruptions in breathing during sleep. It manifests more frequently by loud, chronic snoring8

This is the first version of the Withings Health Institute's online Observatory. It will evolve over the coming months to feature other data such as sleep data. The purpose of the observatory is to provide a comprehensive health overview covering various vital indicators. These new measures will also enrich existing analyses by making it possible to identify correlations.

All data used by the Withings Health Institute are permanently anonymized and aggregated, built upon a pool of users having accepted the terms and conditions of use of Withings services.
In order to avoid reidentification of individual data, the data aggregation satisfies a minimum threshold relative to the size of each aggregate: if the number of units in each studied class is inferior to the minimum threshold, the corresponding data is excluded and replaced by "N/A". 0 is displayed as a valid numerical data.
Physical activity level classes used are: Sedentary - number of daily steps < 4000 ; A bit active - 4000 ≤ number of daily steps < 7000 ; Moderately active - 7000 ≤ number of daily steps < 10000 ; Active - number of daily steps ≥ 10000.
BMI (Body Mass Index) classes used are those defined by the World Health Organization: Underweight - BMI < 18.5 kg/m2 ; Normal - 18.5 ≤ BMI < 25 kg/m2 ; Overweight - 25 ≤ BMI < 30 kg/m2 ; Moderate obesity - 30 ≤ BMI < 35 kg/m2 ; Severe obesity - 40 ≤ BMI < 40 kg/m2 ; Morbid obesity - BMI ≥ 40 kg/m2. Therefore, the prevalence of overweight and obesity corresponds to the percentage of subjects with a BMI greater than or equal to 25 kg/m2.
Blood pressure classes used are those defined by the American Heart Association: Hypotension - systolic pressure < 90 mmHg / diastolic pressure < 60 mmHg ; Normal - 90 ≤ systolic pressure < 120 mmHg / 60 ≤ diastolic pressure < 80 mmHg ; Prehypertension - 120 ≤ systolic pressure < 140 mmHg / 80 ≤ diastolic pressure < 90 mmHg ; Hypertension - systolic pressure ≥ 140 mmHg / diastolic pressure ≥ 90 mmHg.
