How to Tell If Your Low Blood Pressure Is Dangerously Low? All On Living With Hypotension
Low blood pressure, also known as hypotension, is usually considered a sign of good health and low risk for cardiovascular disease. However, there are times when persistently low blood pressure or a sudden drop can be a sign of an underlying health issue that needs medical attention. Knowing when low blood pressure becomes a problem can help ensure timely intervention and proper care.
Systolic pressure (the top number) indicates the pressure in your arteries when your heart pumps blood. Diastolic pressure (the bottom number) reflects the pressure in your arteries while your heart is resting between beats.
The normal reading is usually 120/80 mmHg or less. Hypotension is clinically defined as having blood pressure readings less than 90/60 mmHg. In some patients, low blood pressure will have no adverse health consequences and therefore does not need to be treated. In extreme cases, however, it can limit the flow of oxygen and nutrients to vital organs, resulting in potentially life-threatening complications, such as shock.
Hypotension can result from many factors. Some of the factors that cause hypotension are as follows:
While low blood pressure may not always cause symptoms, it can sometimes be associated with:
- Dizziness or fainting
- Fatigue and weakness
- Blurred vision
- Nausea
- Confusion or difficulty concentrating
- Shallow breathing
- Palpitations
If the person experiences these symptoms, with the recorded blood pressure reading, the medical services have to be consulted.
1. Orthostatic Hypotension: This is a kind of hypotension that appears as a result of decreased blood pressure when a person is standing up from lying down or sitting position and primarily affects elderly people.
2. Postprandial Hypotension: This is a drop in blood pressure after eating, more common in older people.
3. Neurally Mediated Hypotension: It is triggered by standing for long periods. This type can affect younger people and is associated with miscommunication between the brain and heart.
There is no such thing as a universal threshold for very low blood pressure, but a blood pressure reading below 90/60 mmHg can be dangerous and require prompt medical assessment if accompanied by symptoms of fainting, confusion, or shortness of breath. Sudden falls in blood pressure may point to potentially serious underlying causes, which can include:
Treatment of hypotension depends on its cause:
For more severe cases, physicians might also administer fludrocortisone or midodrine to increase blood pressure. Shock from hypotension should be treated promptly to ensure proper function of organs.
Chronic fatigue syndrome has also been associated with low blood pressure. Prolonged tiredness, despite adequate rest, may require reassessment of blood pressure levels. Fatigue secondary to hypotension will impact functionality and thus requires assessment and treatment of the cause.
If your blood pressure readings are low consistently and without symptoms, you probably have nothing to worry about. If you do have symptoms like dizziness, fainting, or confusion, you need to go to the doctor. Blood pressure checks are usually conducted regularly. Once you are aware of your own normal baseline, you will know right away when there is something wrong.

The NHS has released updated guidance for people who are currently taking clonazepam, a commonly prescribed medicine that belongs to the benzodiazepine group. According to the health service, clonazepam is often used to control seizures or fits linked to epilepsy, ease involuntary muscle spasms, and help manage panic disorders. It is also prescribed in some cases for people with restless legs syndrome (RLS). NHS Inform notes that “around 1 in 10 people experience restless legs syndrome at some stage in their life.”
Explaining how the drug works, the NHS says it increases levels of gamma-aminobutyric acid (GABA), a chemical in the brain that has a calming effect. By boosting GABA, clonazepam can reduce anxiety, prevent seizures or fits, and relax tight or overactive muscles.
Clonazepam is only available on prescription and comes as tablets or a liquid. Most adults aged 18 and over can take either form. In certain cases, children as young as one month old may be prescribed clonazepam to treat epilepsy, as per NHS.
That said, there are situations where extra caution is needed. People who are due to have surgery or dental treatment, those who are pregnant, trying to conceive, or who have sleep-related conditions may be advised to stop taking the medicine. However, these are not the only groups the NHS says should be careful.
Clonazepam is not suitable for everyone. Before starting treatment, patients are advised to tell their doctor if they:
Like many medicines, clonazepam can cause side effects. Common effects, which affect more than 1 in 100 people, include disturbed sleep such as vivid dreams, feeling sleepy during the day, light-headedness, dizziness, unsteadiness, and muscle weakness.
When it comes to long-term use, the NHS warns that clonazepam can lead to withdrawal symptoms if taken for a prolonged period. Because of this risk, people who have been prescribed the drug for more than four weeks may have their dose reduced slowly when stopping treatment, rather than stopping suddenly.
The NHS also stresses that this is not a complete list of side effects. Patients are advised to read the information leaflet that comes with their medicine for full details.
Although uncommon, some people may experience serious side effects while taking clonazepam. The NHS advises contacting a doctor or calling 111 immediately if you notice:
In rare cases, clonazepam can trigger a serious allergic reaction known as anaphylaxis.

Every winter, people in Delhi prepare themselves for stinging eyes, tight chests and coughs that refuse to go away as thick smog blankets the city. Now, fresh research from Jawaharlal Nehru University (JNU) suggests there is another hidden danger in the polluted air. According to the study, Delhi’s winter smog may also be carrying antibiotic-resistant bacteria, adding to health worries in one of the most polluted cities on the planet.
The research, titled Distribution and antibiotic resistance patterns of airborne staphylococci in urban environments of Delhi, India, was published in Nature – Scientific Reports. It found disturbingly high levels of antibiotic-resistant “superbugs” in both indoor and outdoor air across the city, particularly in winter when pollution levels spike. The findings point to polluted air acting as a possible vehicle for antimicrobial resistance (AMR), which experts already consider one of the gravest global health threats.
As per Indian Express, to understand what people might be breathing in, the researchers collected air samples from a range of everyday locations across Delhi, such as:
Both indoor and outdoor air samples were taken during summer, monsoon and winter to track how bacterial levels and resistance patterns shifted with the seasons.
Across every setting, airborne bacteria levels were far above the World Health Organization’s recommended safe limit for microbial exposure. In some winter samples, bacterial counts exceeded 16,000 colony-forming units per cubic metre, which is more than 16 times higher than the WHO guideline.
What raised even greater concern was the type of bacteria detected. Many belonged to the Staphylococcus group, which includes strains linked to skin infections, pneumonia, bloodstream infections and illnesses commonly acquired in hospitals.
According to the researchers, a large share of the airborne bacteria were identified as methicillin-resistant staphylococci (MRS), meaning they do not respond to commonly prescribed antibiotics. Among these:
Notably, 14 out of 36 multidrug-resistant samples carried the mecA gene, a well-known marker that makes bacteria resistant to methicillin and related antibiotics.
The study showed that levels of airborne drug-resistant bacteria were highest in winter, while monsoon rains led to a sharp drop in outdoor contamination.
Researchers point to a few likely reasons:
On the other hand, rainfall during the monsoon appears to clear bioaerosols from the air, reducing bacterial concentrations outdoors.
Many healthy people may breathe in these bacteria without becoming sick. However, the risk is much higher for:
The researchers note that inhaling drug-resistant bacteria does not automatically lead to infection. Still, it raises the risk of infections that are harder to treat, especially if the bacteria manage to enter vulnerable parts of the body.

Researchers say consuming excessive short-form videos on social media may lead to 'brain rot' and cause cognitive decline, increase the risk of depression and worsen behavior in young children and adults.
Named as the 2024 Oxford University Word Of The Year, 'brain rot' is defined as the supposed deterioration of a person’s intellectual state due to overconsumption of low-quality online content such as TikTok videos, Instagram reels and YouTube Shorts.
Until now, brain rot was considered to be merely internet slang but now multiple studies show that the condition can, indeed, impact overall brain health and pave the way for neurodegenerative diseases.
According to a literature review published in Psychological Bulletin, a journal of the American Psychological Association, scientists found links between heavy consumption of such videos and increased symptoms of depression, anxiety, stress and loneliness.
Additionally, the September 2025 study also found that extreme intake of short form videos (SFVs) can worsen cognitive functioning and weakening emotional control as well as regulation.
Moreover, an October 2025 study from Capella University, Minneapolis which summarized 14 studies on SFVs discovered that people who regularly watch videos, ranging between 15 to 60 seconds, were prone to developing 'TikTok Brain' and suffered from low attention spans.
The review noted, "Reports from educators and parents describe teens struggling to focus in class or during prolonged tasks, behavior changes often attributed to constant stimulation from social media scrolling."
Based on these results, Keith Robert Head, a doctoral student in social work at Capella University and study author commented, "So one of the questions that would be interesting for researchers to study is: Are these ADHD diagnoses actually ADHD, or is it an impact from the continued use of short-form video?"
James Jackson, a neuropsychologist at Vanderbilt University Medical Center told NBC News, "The narrative that the only people who are worried about this are grumpy old grandpas who are yelling at you to get off their lawn or the idea that if you’re concerned about this you’re not in step with the times, I think that’s really simplistic."
He also noted that SFVs can be useful through the opportunities it creates for learning as well as community-building and social media users should seek to maintain a balance.
“There are people that engage with short-form videos in ways that are value-added, for sure. But if their engagement is pulling them away from other, more healthy opportunities, if it is isolating them from other people, if it is creating situations where they’re less and less likely to just sit around and be bored, I think that’s a problem," he said.
She further noted that it may take many years of study to determine whether cognitive changes associated with SFVs consumption are reversible and whether they can qualify as an 'addiction'
“It might be too early to claim universal doom,” Gupta said. “The research for alcohol, cigarettes and drugs took 75 years or more to develop. But I would be surprised if, in the next five to 10 years, we do not have similar signs validating the moral panic that we have around short-form videos.”
