Yes, a lack of sleep is strongly linked to high blood pressure (hypertension); getting fewer than 7-9 hours of quality sleep nightly increases your risk, as insufficient rest disrupts the body's blood pressure regulation, potentially leading to higher daytime and nighttime readings and increased cardiovascular risk. Sleep deficiency can also worsen other risk factors like obesity and diabetes, further contributing to hypertension.
Too much salt in the diet. Drinking too much alcohol (more than 1 to 2 drinks per day) Older age. Family history of high blood pressure (heredity)
These natural ways to lower blood pressure can keep you healthy.
Sleep deprivation symptoms include cognitive issues (poor focus, memory, decision-making), mood changes (irritability, anxiety, depression), physical signs (fatigue, yawning, headaches, weakened immunity), and performance deficits (slowed reactions, increased mistakes, accidents). Severe deprivation can even lead to hallucinations or psychosis, while long-term lack of sleep impacts weight, heart health, and hormonal balance.
When you're asleep your blood pressure is generally lower than while you're awake. This is totally normal and is known as nocturnal dipping. The drop in both your systolic (the top number) and diastolic (bottom number) blood pressure can be up to 20% lower than your readings in the day time.
The study found that sleeping less than seven hours was associated with a 7% increased risk of developing high blood pressure, which spiked to 11% when reported sleep duration was less than five hours. By comparison, diabetes and smoking are known to heighten one's risk of hypertension by at least 20%, Hosseini said.
Bed rest can help control your blood pressure and may help keep your heart from beating too fast. If your heart rate slows down, less blood will be pumped into your arteries which helps keep your blood pressure stable. As long as your blood pressure remains mild, you can take care of it outside of the hospital.
Sleep deficiency is linked to many chronic health problems, including heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, and depression. Sleep deficiency is also linked to a higher chance of injury in adults, teens, and children.
Adults typically need about 1.5 to 2 hours of deep sleep throughout the night, along with 90 minutes of REM sleep. Anything less, and you may wake up feeling like you didn't sleep at all. Not getting enough deep sleep affects more than how you feel the next day.
This is sometimes described as a period of 'quiet wakefulness'. But is taking a quick rest - closing your eyes, putting your feet up and clearing your mind for a couple of minutes - as beneficial as getting some sleep? The concise answer is 'no'.
The 7 second trick to lower blood pressure refers to a controlled breathing exercise that involves slowing down your breathing rate to calm the nervous system. This technique typically follows a simple pattern: Inhale slowly through your nose for 4 seconds. Exhale gently through your mouth for 7 seconds.
A blood pressure of 140/90 mmHg is Stage 2 hypertension, which needs medical attention and lifestyle changes, but usually not an immediate hospital trip unless you have severe symptoms like chest pain, shortness of breath, vision changes, or signs of stroke, in which case you should call for emergency help (like 911/000) immediately. For a single reading, it's best to recheck after relaxing and then contact your doctor for advice and follow-up, as persistent readings above 140/90 warrant a check-up to prevent long-term damage.
"Stroke level" blood pressure is a hypertensive crisis, defined as a reading of 180/120 mmHg or higher, which is a medical emergency requiring immediate help (call 911 or emergency services) as it significantly increases the risk of a stroke, heart attack, or other life-threatening conditions, especially if accompanied by symptoms like severe headache, shortness of breath, or vision changes.
In hypertensive emergency, call 911 if your blood pressure is higher than 180/120 mm Hg and you are experiencing symptoms that may include:
At the beginning, measure your blood pressure at least twice daily. Take it first in the morning before eating or taking any medicine. Take it again in the evening. Each time you measure, take two or three readings to make sure your results are the same.
Less active, less fit persons have a 30-50 percent greater risk of developing high blood pressure. Physical inactivity is a significant risk factor for CVD itself. It ranks similarly to cigarette smoking, high blood pressure, and elevated cholesterol.
The 3-2-1 bedtime method is a simple sleep hygiene strategy: stop eating 3 hours before bed, stop working 2 hours before bed, and stop using screens (phones, tablets, TVs) 1 hour before sleep, helping your body transition to rest by reducing stimulants and digestive load for better sleep quality. A more detailed version adds 10 hours (no caffeine) and 0 (no snoozing) for a 10-3-2-1-0 rule.
The koala is the animal that sleeps approximately 90% of the day (20-22 hours), a necessity due to its low-energy eucalyptus diet requiring intensive digestion, making it the ultimate champion of sleep in the animal kingdom, followed closely by sloths and bats.
Signs of poor core sleep (deep, restorative sleep) include waking up foggy, daytime fatigue/energy crashes, poor concentration, irritability, frequent illness, memory issues, and mood swings, indicating your brain and body aren't fully repairing and consolidating memories. You might also experience increased sugar cravings, slow muscle recovery, and a weakened immune system.
While every organ in the body is affected by poor sleep, the brain takes the biggest hit, showing signs of dysfunction faster than any other system. Over time, the heart, liver, and immune system also begin to show stress, which can increase your risk of chronic illness.
Stick to a sleep schedule
Go to bed and get up at the same time every day, including weekends. Being consistent reinforces your body's sleep-wake cycle. If you don't fall asleep within about 20 minutes of going to bed, leave your bedroom and do something relaxing.
Whether you prefer a cold drink or a warm bedtime drink, here's our list of the best drinks before bed to help you drift off.
Tips for better sleep if you have high blood pressure
If you get a blood pressure reading of 180/120 or higher more than once, seek medical treatment right away. A reading this high is considered “hypertensive crisis.” Readings between 120/80 and 129/89 are considered pre-hypertension.
In other words, once blood pressure rises above normal, subtle but harmful brain changes can occur rather quickly—perhaps within a year or two. And those changes may be hard to reverse, even if blood pressure is nudged back into the normal range with treatment.
