Measuring walk smartphones may detect drunkenness
New research finds that a smartphone can accurately detect, based on how they walk, whether the person who has it is drunk.

A recent research found that a person’s smartphone can tell when their concentration of breath alcohol reaches 0.08 percent.
The legal limit for driving in the US is a concentration of 0.08 percent of blood alcohol. Measures for breath alcohol are 15 percent lower than blood alcohol levels on average.
The study, which appears in the Journal of Studies on Alcohol and Drugs, could be helpful in advising people when they are in danger of causing harm because of the amount they have been drinking.
Alcohol consumption
Many people worldwide enjoy drinking alcohol responsibly, without hurting themselves or others. But alcohol is also the primary or indirect cause of significant health conditions, illnesses, and deaths.
Alcohol use is the third leading cause of preventable death in the U.S., behind smoking and issues related to physical activity and diet, according to the National Institute on Alcohol Abuse & Alcoholism. Every year nearly 88,000 people die of causes related to alcohol.
Estimates indicate that 5.8 percent of people 18 or older have alcohol use disorder, a chronic illness that, given its negative effects, can prevent a person from restricting their alcohol consumption.
Consumption of alcohol can impair cognitive and motor function — the ability to think clearly and move carefully and with purpose. This raises the chance of hurting someone else or yourself.
For instance , in 2018, 29 percent of driving deaths in the U.S. involved someone who drank too much.
Finding ways to warn someone who has had too much to drink could be valuable in encouraging them to take more care of themselves.
For Dr. Brian Suffoletto, formerly from the University of Pittsburgh School of Medicine and now from the Department of Emergency Medicine at Stanford Medical School, and the corresponding author of the study, this was personally significant.
“I lost a close friend to a drinking and driving crash in college , ” Dr. Suffoletto says. “And as an emergency physician, I took care of counts of adults with acute alcohol intoxication-related injuries. For this reason, over the past 10 years I have committed myself to researching digital solutions to avoid deaths and injury linked to excessive alcohol use.
Although devices such as portable breath analyzers are available, there are obstacles to their use: they are costly, and a person’s social stigma may stop using one overnight.
Smartphones may be an alternative: 81 percent of people in the U.S. own smartphones and the vast majority of smartphones have advanced sensors that can assess a person’s intoxicated status.
“We have powerful sensors [that] we carry around with us wherever we go. We need to learn how to use them to best serve public health.”
– Dr. Brian Suffoletto
Straight line walking
Previous research has revealed that smartphones can determine if a person is drunk using their gait information — how they walk. Starting in 2016, one study used machine learning to assess if a person was inebriated.
The authors wanted to see in the present study whether smartphones measuring gait could tell whether a person had reached an objective measure of intoxication: a 0.08 percent concentration of breath alcohol, the amount at which people appear to show poor coordination.
For the research, 22 people who visited a laboratory were recruited to consume a vodka-based drink that would increase their concentration of breath alcohol to 0.2 percent.
Each individual had a mobile attached to their back before drinking the alcohol and was asked to take 10 steps in a straight line, then back again. The guests repeated their walks every hour for the next 7 hours.
The sensors on the smartphones measured the acceleration of each participant, their side-to – side movements and their up and down motions.
Over 90% accurate
By analyzing the data , the researchers found that 92.5 percent of the time a participant could be determined to have exceeded the legal limit of 0.08 percent blood alcohol concentration.
“This controlled lab study shows that our phones can be useful to identify ‘signatures’ of functional impairments related to alcohol.”
– Dr. Brian Suffoletto
There are certain limitations to the study. A person is unlikely to keep their phone strapped to their back, and the results could be affected by changing their location, carrying it or putting it in a bag or pocket for example.
The study also measured concentrations of breath alcohol, which are on average 15 per cent lower than concentrations of blood alcohol. Hence, a concentration of breath alcohol above 0.068 percent would suggest a concentration of blood alcohol above the legal limit of 0.08 percent. It will take more testing to determine how effective the software is at those lower levels.
This was a small proof of study of the concept. Future research is required with substantially more participants and, preferably, real-world study, to confirm that smartphones can be used frequently for this purpose.
Nonetheless, this study lays the groundwork for further research.
“In 5 years, I would like to imagine a world in which, if people go out with friends and drink at risky levels, they get an alert at the first sign of impairment and are sent strategies to help them stop drinking and protect them from high-risk events, like driving, interpersonal violence, and unprotected sexual encounters.”

Rhinophyma: Everything you should know
Rhinophyma is a skin condition that causes the nose to expand. Lumpy, thicker skin and fractured blood vessels are some of the other signs.
Males are far more likely than females to get the condition, which usually occurs between the ages of 50 and 70.
Researchers aren’t sure what causes it, but they do know that acne rosacea, which causes inflammatory pimple breakouts, is a precursor.
When acne rosacea advances to rhinophyma, the skin around the nose swells and the tip of the nose becomes larger. A diagnosis is made based on this distinctive appearance.
In the early stages, medicines are used, but in the latter stages, surgery is required. This is due to the possibility of damaged tissue obstructing the airways. The technique is safe and effective at smoothing or removing rough, thickened patches of skin.
Continue reading to find out more about the causes, symptoms, diagnosis, and treatment of this condition.
Causes of rhinophyma
Rhinophyma is characterized by an increase in the number of sebaceous glands (oil glands) and underlying connective tissues in the face. According to studies from 2021, the actual cause is still unknown, and various causes could be involved. A variety of disorders affecting the immune system, nerves, and blood arteries are included.
Acne rosacea, a long-term skin condition more common in women, is the prelude to rhinophyma. Rhinophyma develops in a subset of acne rosacea people.
Rhinophyma is more common in men, with a male-to-female ratio ranging from 5:1 to 30:1, and it usually develops in people between the ages of 50 and 70. Scientists believe that male hormones raise the danger because of the higher prevalence in men.
Some people believe that drinking alcohol causes the condition, however studies show that this is not the case. However, both alcohol and caffeine enlarge blood vessels briefly, aggravating rhinophyma.
In its early beginnings
According to evidence, rhinophyma begins as “pre-rosacea,” with face flushing being the only symptom.
The condition progresses to vascular rosacea, which is characterized by enlarged blood vessels and redness. Acne rosacea causes later, resulting in inflammatory outbreaks.
Finally, acne rosacea progresses to late-stage rosacea, which includes rhinophyma.
Symptoms
The first symptom of rosacea is frequently excessive face flushing. If it evolves to rhinophyma, a person may experience the following symptoms:
- thickened skin on the nose and elsewhere on the face
- expansion of the tip of the nose
- a bumpy texture on areas of the face
- enlarged pores
- oily skin
The condition may restrict the airways at this moment. In addition, because the fluid from the sebaceous glands thickens and can contain bacteria, persistent infection is common.
The amount of sebaceous glands and connective tissue alterations grow with time, resulting in increasing deformity.
Furthermore, there is a relation to cancer. Basal cell carcinoma affects 3–10% of people with rhinophyma, despite the fact that the condition is initially benign.
Diagnosis
Rhinophyma is often diagnosed with a visual examination due to its distinctive look.
The presence of at least one primary feature and at least one secondary feature is used by doctors to make a diagnosis.
The following are the main characteristics:
- blushing
- persistent redness
- pustules, small pimples containing pus
- papules — small, solid pimples that are usually inflamed but do not produce pus
- broken or dilated blood vessels near the skin’s surface
Secondary features include:
- roughened patches of skin on the face
- swelling
- burning or stinging areas of the skin
- eye symptoms, such as watery eyes or swelling of the eyelids
- marked thickening of skin or excess tissue
- these symptoms elsewhere on the body
Treatment
There are nonsurgical and surgical options available.
Non-surgical options
Certain drugs appear to be beneficial, according to the findings. Topical metronidazole (Metrocream) is one option for reducing skin inflammation by preventing the production of reactive oxygen species.
Isotretinoin, a medicine that shrinks the sebaceous glands and reduces the amount of oil they produce, is another choice. If a person wants surgery, however, they must stop taking this drug.
Surgical intervention
Advanced rhinophyma necessitates surgical removal of the afflicted tissue. A report published in 2020 describes a five-step surgical procedure for rhinophyma that is both safe and effective:
- Dermabrasion: A motorized device resurfaces the skin to facilitate the next steps.
- Dermaplaning: This involves removing affected tissue without directly cutting it. It prepares the skin’s surface for the third step.
- Debulking: The surgeon uses curved scissors to cut away the thickened skin. They also take samples of any areas that may be malignant and send them to a lab for analysis.
- Electrocautery: This involves using heat to destroy the affected tissue.
- Laser use: This final step seals and micro-contours the wound.
Although little data suggests that rhinophyma can recur following surgery, few long-term studies have been conducted.
Conclusion
A person with rhinophyma may suffer significant face flushing in the early stages. Swollen blood vessels and acne-like blemishes occur as the condition worsens.
Later on, the nasal skin thickens and the tip of the nose expands. Doctors diagnose rhinophyma at this point. It appears to be harmless at first, but it has the potential to obstruct airways and raise the risk of skin cancer.
Surgical and drug-based treatments can help, although there is limited evidence that the condition will reoccur after surgery.

Alcohol and migraine: What you need to understand
Many people with migraine find that specific situations trigger their symptoms. Drinking alcohol is a trigger for some people with migraine. Although any type of alcohol can provoke a migraine, people who experience recurrent migraine attacks cite red wine as the most frequent reason.
Research suggests that people with migraine may also suffer comparable symptoms after a hangover. Reducing or eliminating alcohol may reduce the frequency of migraine attacks. It may also help reduce factors that tend to co-occur with drinking, such as dehydration and sleep deprivation.
Keep reading to understand more about the connection between migraine and headache.
Is alcohol capable of causing migraines?

Migraine is a form of neurological disorder. Although hereditary factors impact the chance of developing migraine, environmental triggers can cause episodes or increase their frequency.
Several studies show that alcohol, especially red wine, may cause migraine episodes.
In a 2018 research including 2,197 adults with migraine, 25% of the participants who had discontinued or always avoided drinking did so because alcohol induced migraine symptoms. More than a third of the subjects stated that alcohol had this impact, with roughly 78% indicating red wine as the most prevalent alcohol trigger.
A 2019 research questioned patients with migraine who consumed alcohol. Of the 1,547 individuals, 783 claimed that alcohol was a trigger, while 195 were not sure. People who experienced migraine with alcohol were more likely to suffer migraine with aura and to experience more migraine days and more frequent episodes. They were also more prone to drink vodka.
A predisposition for migraine may also play a role in hangovers, especially hangovers that induce migraine-like headaches. A 2014 study of 692 students, 95 of whom experienced migraine, indicated that individuals with migraine were more likely to suffer migraine-like symptoms during a hangover. However, these people were not more prone to other hangover symptoms.
Alcohol may also create other sorts of headaches. People who get a headache after drinking should not assume that it is a migraine, especially if they have symptoms associated with other forms of headaches. For example, a stress headache may induce pain in the neck or shoulders.
Other alcohol-related headaches
Migraine creates a unique form of headache that incorporates neurological symptoms such as light sensitivity and aura. Other sorts of headaches, including severe headaches, can occur as a result of alcohol intake.
Hangover headache
A headache is a frequent hangover symptom. Alcohol can provoke symptoms in persons with a headache disease, but it can also directly induce headaches.
A 2015 study shows that the inactivity of alcohol dehydrogenase 2, an enzyme that helps break down alcohol, can contribute to hangover headaches. However, the research author also notes that no one factor causes all hangover headaches.
Tension headache
A 2016 study emphasizes that drinking may induce a tension headache, especially if a person simultaneously suffers migraine. The research revealed that 21 percent of persons with migraine indicate that alcohol is a tension headache trigger, compared with just 2 percent of people without migraine.
Cluster headache
Alcohol may provoke cluster headaches. These headaches induce very strong pain that generally predominantly affects the region behind one eye. More than half of individuals who get cluster headaches indicate that alcohol is a trigger.
Dehydration headache
Alcohol increases urine, which can contribute to dehydration. Moreover, persons who drink alcohol may not drink as much water, exacerbating the water loss. Dehydration can induce headaches. It may also provoke headaches connected to headache diseases, such as migraine.
What alcohol to consume to avoid migraine attacks
Most research point to red wine as a prevalent headache trigger, particularly in those with migraine. These individuals typically report wine, especially red wine, as a migraine trigger.
However, a 2012 research denies this relationship. This prospective research looked at migraine diaries extending up to 90 days. Wine, beer, and spirits did not enhance the risk of migraine with aura, while sparkling wine did.
People who have hangovers that induce a migraine may desire to avoid alcohol with high amounts of congeners. These are compounds that the alcohol production process creates. Some study shows that congeners have a role in hangovers, however variables like as inflammation also contribute.
Brandy, red wine, and rum have the largest quantities of congeners, whereas gin and vodka have fewer of these compounds. However, a 2019 study reported greater rates of vodka use among drinkers with recurrent migraine symptoms. The reaction to alcohol varies from person to person, and there is no drink that certainly will not trigger a migraine or other headache.
Other migraine-prevention options
Identifying and limiting or eliminating common migraine triggers such as alcohol, dehydration, and specific meals is the first step in preventing migraine. For a few weeks, a person should keep a migraine diary to detect trends in their headache patterns.
Stress-related migraines may be relieved with relaxation techniques, and migraine episodes may feel less severe when they occur.
Migraine prophylaxis drugs such as topiramate (Topamax), divalproex (Depakote), or propranolol may be useful for people who suffer frequent migraine attacks (Inderal). They can talk to a doctor about these therapy alternatives.
People who suffer from migraines while or after drinking may consider limiting or eliminating alcohol from their diet. If they find this too difficult, they may be suffering from an alcohol use disorder, which need therapy.
Conclusion
Migraine attacks can range from minor inconveniences to complete debilitation. The most severe migraine headaches can last up to three days and render you unable to work. In rare cases, a migraine attack can persist much longer.
Migraine is a complicated disorder, and migraine-like symptoms can be caused by a variety of neurological conditions. As a result, whether you’re drinking or not, it’s critical to consult a doctor if you’re experiencing migraine symptoms or chronic headaches. Migraine headaches can be treated with the appropriate combination of medicines and lifestyle changes.
People who are unable to stop drinking should consult a physician about alcohol use disorder treatment, which is a serious but treatable problem.
