Can snorkeling cause broken blood vessels in the eye?

While snorkeling is generally a safe and enjoyable activity, there are certain risks and potential hazards that should be considered. One potential risk is sudden pressure changes, which can occur when diving down or surfacing too quickly. Rapid pressure changes can cause damage to the blood vessels in the eyes, ears, and sinuses, leading to conditions such as barotrauma or decompression sickness. However, it's important to note that these risks are typically associated with scuba diving and free diving at significant depths, rather than casual snorkeling at shallow depths.

Snorkeling at the surface involves relatively minor pressure changes compared to scuba diving, and the risk of severe pressure-related injuries is low. Nevertheless, it's always advisable to follow basic safety guidelines when snorkeling, such as descending and ascending gradually to allow your body time to adjust to pressure changes. If you experience any discomfort, pain, or unusual sensations in your eyes, sinuses, or ears during or after snorkeling, it's important to stop the activity and seek medical attention as soon as possible.

Here are some tips to help you minimize the risks associated with pressure changes while snorkeling:

1. Descend and ascend slowly: Take your time when moving up or down in the water. Rapid changes in depth can increase the risk of pressure-related injuries.

2. Stay within safe depths: Casual snorkeling should generally be done in shallow water, within a depth range that allows you to maintain easy control over your buoyancy and ascent rate.

3. Equalize your pressure: If you feel pressure in your ears or sinuses, you can equalize by gently exhaling through your nose while holding your nose closed and swallowing at the same time.

4. Take breaks: Avoid snorkeling for extended periods without taking breaks to rest and allow your body to adjust to pressure changes.

5. Be aware of your surroundings: Avoid swimming underneath boats, piers, or other structures that could suddenly block your ascent and cause rapid pressure changes.

6. Stay hydrated: Drink plenty of water before, during, and after snorkeling to help your body maintain proper fluid balance and reduce the risk of decompression sickness.

If you have any pre-existing medical conditions, it's always advisable to consult with a doctor or medical professional before engaging in snorkeling or any other water-based activities. By following these tips and taking necessary precautions, you can help ensure your snorkeling experiences are safe and enjoyable.
