- Sit down with your head lowered forward between yourknees.
- Don't let yourself get dehydrated.
- Keep blood circulating.
- Avoid overheated, cramped, or stuffy environments, wheneverpossible.

- Muscle weakness or cramps.
- Nausea and vomiting.
- Rapid heartbeat, which may be either strong or weak.
- Rapid, shallow breathing.
A heat illness can be very mild, like askin rash, or more serious, even heat stroke. rises above106° F. It can lead to death, if the person does notget medical attention right away. Cramps: It is a painyou feel when a muscle becomes very tight. Overheat: Whenyou become so hot that you get sick.
Heat syncope is a sudden dizziness thatcan happen when you are active in hot weather.If you take a heart medication called a beta blocker or arenot used to hot weather, you are even more likely tofeel faint. Rest in a cool place, put your legs up, anddrink water to make the dizzy feeling goaway.
Heat intolerance is a feeling of being overheatedwhen the temperature around you rises. It can often cause heavysweating. Heat intolerance usually comes on slowly and lastsfor a long time, but it may also occur quickly and be a seriousillness.
Causes of fainting
- fear or other emotional trauma.
- severe pain.
- a sudden drop in blood pressure.
- low blood sugar due to diabetes.
- hyperventilation.
- dehydration.
- standing in one position for too long.
- standing up too quickly.
Common causes of syncope include:
- low blood pressure or dilated blood vessels.
- irregular heart beat.
- abrupt changes in posture, such as standing up too quickly,which can cause blood to pool in the feet or legs.
- standing for long periods of time.
- extreme pain or fear.
- extreme stress.
- pregnancy.
- dehydration.
This means your heart doesn't have to work as hard topush blood up to your brain. You should return to consciousnessafter about 20 seconds. Call emergency services and ask for anambulance if someone faints and doesn't regain consciousness withintwo minutes.
Another kind of fainting can happen whenyou stand up from sitting or lying down, andyour blood pressure drops quickly. This causes dizziness,lightheadedness or a brief loss of consciousness. It's alsohighly uncommon for someone to faint for no reasonwhile doing some type of physical activity orexercise.
Coughing, urinating, and stretching can also getin the way of the flow of oxygen to the brain and may causeyou to faint. A drop in your blood sugar may alsocause you to faint. This can happen ifyou have diabetes. It may also happen if you don'teat for a long time.
If the syncope is prolonged, it can trigger aseizure. You may suffer from a simple fainting spell due toanxiety, fear, pain, intense emotional stress, hunger, oruse of alcohol or drugs. This condition is called posturalhypotension and may be severe enough to causefainting.
The human body needs food and water to survive. Ahuman can go for more than three weeks without food —Mahatma Gandhi survived 21 days of complete starvation — butwater is a different story.
A Serious Look at Fainting. In a young, healthyperson, 1 episode of fainting is not usually cause foralarm. But in rare cases, it can be a sign of a serioushealth condition. Syncope is usually caused by a sudden drop inblood pressure or heart rate that causes decreased blood flow tothe brain.
Extreme weather can trigger a stress reaction bythe body, causing it to release substances “that notonly increase the work of the heart” but make blood stickierand more likely to clot, Stemer said. Researchers tracked onlystrokes caused by clots, not the less common kindcaused by a burst or bleeding blood vessel.
When you spend too much time in the sun, your internalbody temperature goes up. That can lead to heat rashor heat exhaustion. It happens when your body is sohot it can't cool itself. You're at even more risk ifyou don't drink enough liquids or you're pregnant, overweight,elderly, very young, or have heart disease.
Usually, your hypothalamus and autonomic nervous systemkeep your body within a degree or two of your normaltemperature. However, there are times when your bodyheat rises. This condition is known as heat stress.Heat stress may be due to extreme heat, certainfoods, or other factors.
Orthostatic hypotension — also called posturalhypotension — is a form of low blood pressure that happenswhen you stand up from sitting or lying down. Orthostatichypotension can make you feel dizzy or lightheaded, andmaybe even faint. Orthostatic hypotension may be mild and last forless than a few minutes.
Vasovagal syncope (vay-zoh-VAY-gul SING-kuh-pee)occurs when you faint because your body overreacts to certaintriggers, such as the sight of blood or extreme emotional distress.The vasovagal syncope trigger causes your heart rate andblood pressure to drop suddenly.
A person may be unconscious for a few seconds — asin fainting — or for longer periods of time. Peoplewho become unconscious don't respond to loud sounds or shaking.They may even stop breathing or their pulse may becomefaint. This calls for immediate emergencyattention.
A drop in blood flow to the brain causesfainting. The most common causes of faintingare usually not signs of a more serious illness. In thesecases, you faint because of: The vasovagalreflex, which causes the heart rate to slow and theblood vessels to widen, or dilate.
During attacks, you may look pale and feelsweaty. Your eyes will usually stay open. Orthostatichypotension: this is a fall in blood pressure on standing up, whichcan cause fainting. Due to medication prescribed tolower blood pressure.
Fainting (syncope) is a sudden temporary loss ofconsciousness that usually results in a fall. When youfaint, you'll feel weak and unsteady before passingout for a short period of time, usually only a few seconds. Theremay not be any warning symptoms, but some people experience:yawning.
Cold showers increase yourcirculation
In that sense, a cold shower has the oppositeeffect of a hot shower for someone with hypertension orcardiovascular disease, since exposure to cold temperaturestriggers the circulatory system to reduce inflammation and can helpprevent cardiovascular disease.Fainting can also be caused by a fall inblood pressure when you stand up. dehydration – ifyou're dehydrated, the amount of fluid in your bloodwill be reduced and your blood pressure willdecrease; this makes it harder for your nervous system to stabiliseyour blood pressure and increases your risk offainting.
Position the person on his or herback.
If there are no injuries and the personis breathing, raise the person's legs above heart level— about 12 inches (30 centimeters) — ifpossible. Loosen belts, collars or other constrictive clothing. Toreduce the chance of fainting again, don't get the person uptoo quickly.Heat causes an increase in blood flow to the skinand pooling of blood in the legs, which can lead to a suddendrop in blood pressure. There can be a feeling oflight-headedness before fainting occurs. It occurs whenexcessive sweating in a hot environment reduces the bloodvolume.
Heat syncope occurs when a person faints suddenlyand loses consciousness because of low blood pressure. Heatcauses the blood vessels to expand (dilate), so body fluid movesinto the legs by gravity, which causes low blood pressure and mayresult in fainting.
Prolonged sun exposure can easily irritate oursensitive skin which creates an inflammatory response thatresonates throughout the whole body. If you've ever felt lethargic,achy, or experienced general 'under-the-weather' type feelingsafter sun exposure, this immune response may be theculprit.
Complications of heat exhaustion includenausea, vomiting, dehydration and muscle weakness.If the activity is not stopped and the person left in ahot environment, there can be progression of symptomsto heat stroke, a life-threatening emergency.
Sun poisoning is characterized by symptomssimilar to an allergic reaction. Itchiness, bumps, or blisters: Theskin may become itchy, and bumps or blisters may appear on theaffected area. The skin may be red or swollen, as well. Darkeningof the skin: In some cases, the skin affected may becomedarker.

- Pain and tingling.
- Swelling.
- Headache.
- Fever and chills.
- Nausea.
- Dizziness.
- Dehydration.
You feel fatigue or like you mightfaint
Heat syncope, or orthostatic dizziness, occurswhen exposure to high temperatures reduces blood flow to the brain.Prolonged standing or moving from sitting to standing after havingbeen static for an extended period can exacerbate thecondition.
