Why Is My Head Spinning After Cycling: 7 Potential Causes

7 Possible Causes of Head Spinning After Cycling

Spinning in the head after cycling can be unsettling. You can prevent this issue in the future by understanding the possible causes behind it. Here are some common causes:


Dehydration happens when your body doesn’t have enough water. During cycling, especially when it’s hot, you can lose fluids through sweat. Here’s how dehydration connects to head spinning:

Dehydration and Dizziness: Insufficient hydration affects blood volume and circulation. Dehydration can cause dizziness and lightheadedness as your blood pressure drops.

Low Blood Sugar

Blood sugar (glucose) gives you energy for physical activities. When you cycle, you burn calories and low blood sugar, which can lead to head spinning:

Hypoglycemia and Dizziness: Low blood sugar levels affect brain function. Symptoms include dizziness, weakness, and confusion.


Sometimes, we push ourselves too hard during cycling. Overexertion can cause various symptoms, including head spinning:

Excessive Effort and Dizziness: When you exceed your fitness level, your body struggles to cope. Oxygen supply to the brain may decrease, causing dizziness.


Vertigo is when you feel like everything is spinning. While cycling, vertigo can happen due to different reasons:

Inner Ear Issues: Problems with the inner ear’s balance system can cause vertigo, which sudden head movements during cycling may exacerbate.

Poor Posture during Cycling

Incorrect posture affects your body’s alignment and blood flow. Poor cycling posture can lead to head spinning:

Neck and Spine Alignment: Leaning too far forward or tilting your head excessively strains neck muscles and disrupts blood flow.

Affecting Health Conditions

Cycling can cause head-spinning due to certain health conditions:

Anemia, Hypotension, or Heart Issues: Conditions like anemia (low iron), blood pressure, or heart problems affect circulation and oxygen delivery.

Proper Gear and Positioning

Your cycling gear and bike setup play a significant role in preventing head spinning:

  • Helmet Fit: An ill-fitting helmet can cause discomfort and affect blood flow to the brain.
  • Bike Fit: Incorrect bike positioning strains muscles and affects circulation.
