How to prevent vasovagal syncope?

Vasovagal syncope is a condition that leads to fainting due to low blood pressure and slow heartbeat. It can be triggered by various factors, including standing up for long periods, dehydration, sudden movements, or emotional stress. If you’re prone to vasovagal syncope, it’s essential to take preventative measures. In this article, we’ll explore the various ways you can prevent this condition from happening.

Stay Hydrated

Drinking enough water is an effective way of preventing vasovagal syncope caused by dehydration. When your body loses fluids through sweating or urination without replacement, your blood volume decreases significantly. This decrease in blood volume causes a drop in blood pressure leading to dizziness and potentially fainting.

Drink at least eight glasses of water every day – That’s what they say! Drinking plenty of water not only helps maintain healthy hydration levels but also improves overall health.

Regular Exercise

Exercising strengthens the cardiovascular system and increases circulation efficiency by contributing to better vascular functioning, which makes it easier for the heart muscles work more efficiently during physical activities.

Some exercises that help with improving vascular function include brisk walking and yoga poses like downward dog stretch are particularly good if combined with deep breathing techniques – this brings us onto our next heading…

Controlled Breathing Techniques

Holding your breath or taking quick shallow breaths lowers oxygen saturation hence inducing low arterial resistance which worsens hypotension symptoms such as light-headedness when experiencing anxiety before occasions such as presentations/interviews . Unfortunately even hearing about someone else giving one may induce anxiety! A helpful trick here is trying out deep-breath exercises before stressful situations just like doing Yoga ujjaii breathe which calms down nerves while promoting relaxation increasing vagal tone (thereby reducing BP).

Here’s how you do it:
1) inhale sharply through both nostrils while focusing on filling your lungs with air
2) gently contract the muscles at the back of your throat and exhale slightly slower than you inhale.

Repeat this for a few cycles, and we guarantee that you’ll feel way better!


It’s essential to follow a healthy eating pattern to reduce vasovagal syncope symptoms from certain food allergies or excess consumption of some foods high in sugar or caffeine is known for triggering fainting spells.

Avoid caffeine, alcohol and sugary drinks – Being mindful of what goes into our tummy can go along when managing vasovagal syncope.


Your doctor may prescribe medication if lifestyle changes do not help curb the frequency of syncopal episodes. Depending on the underlying condition causing low blood pressure including alternative options such as prescription anti-anxiety compounds/antidepressants – sweating it off isn’t always possible!

Legs-Up Technique.

A technique which helps alleviate immediate symptoms during an episode simply; Sit comfortably with legs upward against a wall perpendicularly (forming an ‘L’ shape, hence its name). The leg-up technique alleviates symptoms by aiding venous return to increase cerebral perfusion swiftly.

Avoid Emotional Stressors

Patients are typically advised to avoid stressful situations or engage in activities that promote relaxation whenever possible – this includes various stress-relieving techniques like meditation/ mindfulness exercises or even taking part in animal assisted therapy where cuddling dogs is proven anxiety reducing! . Furthermore individuals prone to looking away when getting their vaccines will be interested to know practitioners nowadays offer numbing sprays sometimes allowing a painless procedure minus flushing colors water down peoples faces 😉

Wear Compression Stockings

Compression stocking/wear recommends increases resistance in prevention from pooling deep system vessels which contribute towards worsened dilation/decreased cohesiveness worsening peripheral circulation; measures have proven especially useful during long-standing period allocation (e.g. flying, sitting behind a desk all day).

Get Enough Sleep

Not how much sleep you get but the quality affects vasovagal syncope prevention. Good-quality sleep is crucial for overall health and influences our bodies’ ability to self-regulate.Maintain good sleeping habits by ensuring bedroom conditions promote relaxation such as minimal A/C noise disruptions that may interrupt circadian rhythm – phones should be off/kept away from reach.

Salt Intake

It’s recommended for patients to consume ample salt (approximately two thousand milligrams daily) – adding flavorful herbs/spices like pepper or rosemary on food items encourage consumption of healthy foods while promoting sodium retention which helps increase vascular resistance upon standing.

Disclaimer if you have high blood pressure, heart failure or both remember it always best consulting your cardiologist before making any dietary changes

Small Lifestyle Changes

Lifestyle impact – further small tactics implemented make it easier managing an individual prone to syncopal episodes:

1) Do not stand too quickly
2) Sit down when feeling lightheaded
3) Shifting positions slowly when performing activities especially first thing in the morning
4) Avoid crossing your legs whilst seated
5) In hot environments remove excess layers of clothing

You can prevent Vasovagal Syncope through taking measures ranging from hypertension therapy(medications), additional fluids during prolonged activity; diet management-avoiding certain edibles/drinks(low-sugar/salt foods), compression stockings, controlled breathing techniques(i.e yoga poses)/ deep breathing with contractions exercises this offers immediate results then there are lifestyle routines changes including deliberate symptom triggering exercises/stress management embrace! Remember seeking personalized medical professional advice improve long-term recovery success !

Good luck preventing fainting spells! 🙂
