Excessive effort

Excessive exertion can make a person feel dizzy after exercising.

Overexertion occurs when people overexert themselves during physical activity. Signs of overexertion are:

  • Dizziness
  • to feel weak
  • Drowsiness
  • Nausea
  • labored breathing
  • thirst
  • to vomit

According to research from 2021, overexertion injuries account for 36.2 percent of all gym injuries.

However, overexertion doesn’t just occur in gyms or exercise classes. It can happen during any activity.

Use of machines with continuous movement

  • The type of exercises a person does can affect whether or not they get dizzy.
  • For example, using an elliptical exercising machine or treadmill that requires continuous movement may be more likely to make you dizzy.
  • Some people experience dizziness or lightheadedness when they stop using the machine. You can feel like you’re moving.
  • This experience is called dizziness. Others experience drowsiness which is a system of illness.


It occurs when the body loses more water than it uses. While dehydration is more common in children and older adults, it can affect people of all ages.

Healthy adults are more likely to be dehydrated due to minor illnesses or vigorous physical activity, especially in hot weather.

Symptoms of dehydration include:

  • Dizziness
  • Dry mouth
  • Extreme thirst
  • Feel weak or dizzy
  • Less frequent urination
  • Fatigue
  • Weakness

Even mild dehydration, in which only 1 to 2 percent of body weight loss, can reason this symptom.

Many people think that thirst is one of the first signs of dehydration, but they are already experiencing dehydration when someone is thirsty.

Lack of oxygen

  • Inadequate breathing during exercise means that some people don’t breathe enough oxygen to meet the needs of their muscles.
  • During exercise, your muscles use more oxygen than usual. Therefore, the heart rate and breathing are accelerated to allow increased oxygen uptake.
  • People who do not breathe often or deeply enough can experience sub-optimal oxygen delivery to the brain. Dizziness is a sign that the brain needs more oxygen.

Low blood pressure

It is the force of the blood that presses against the walls of the arteries.

Healthy blood pressure for most people is less than 120/80 millimeters of mercury (mm Hg). People with low blood pressure or hypotension will have a reading less than 90/60 mm Hg.

Blood pressure is usually lowest within an hour after exercising. However, some people may notice a more sudden drop.

Symptoms of hypotension include:

  • Faint
  • Fatigue
  • Blurred vision
  • Little concentration
  • Nausea

Vigorous activity is more likely to cause low blood pressure, although any action can trigger it.

Some people with hypotension have symptoms when they stand up too fast.

It can be a cause of exercise-induced dizziness during pregnancy.

It’s also the result of dehydration, heart problems, and the use of certain medications.

Low blood sugar level

Low blood sugar or hypoglycemia occurs when the glucose (sugar) in the blood is meager.

Sugar is the body’s primary source of energy.

Your muscles use more glucose than usual during exercise.

As a result, some people have low blood sugar levels during or after exercise.

Symptoms of hypoglycemia include:

  • Dizziness
  • Anxiety
  • Clumsiness
  • Fatigue
  • Hunger
  • Irritability
  • Tremble
  • Sweat

People are more likely to have hypoglycemia when they haven’t had enough to eat before exercising.

It can be a common problem for those who exercise first thing in the morning.

Cardiac arrhythmias

An abnormal heart rhythm is an irregular heartbeat.

Arrhythmias can cause the heart to beat too fast, too slowly, or irregularly.

Many conditions can cause arrhythmias, including heart disease and emotional stress.

Exercise can also trigger or worsen arrhythmias, especially in people with heart disease.

Not all arrhythmias cause symptoms, but when they do occur, they include:

  • Dizziness
  • Change in heartbeat
  • Faint
  • Drowsiness
  • labored breathing
  • Sweat

Even if symptoms do occur, it doesn’t necessarily mean that a person has a severe problem.

However, if the arrhythmia persists, it is always important to consult a doctor.
