According to the Divers Alert Network (DAN), every dive is a decompression dive, as your body absorbs and releases nitrogen whenever pressure changes. This fact is critical to understanding the specific protocols, and why the question, **do you need to decompress at 30 feet**, has an important and nuanced answer for every scuba diver.

Research indicates that dehydration significantly increases the risk of decompression sickness, a key health concern for divers. To ensure a safe and enjoyable experience, it is crucial to understand **what to avoid before scuba diving**, including specific foods, beverages, and activities.

Anemia diminishes the blood's oxygen-carrying capacity, creating significant safety risks for divers. **Can you dive if you have anemia?** The answer is complex, requiring careful medical evaluation and a thorough understanding of the physiological risks involved.

The human ear is sensitive to pressure changes, which is why a safe and effective equalization technique is crucial for divers. For those using the Valsalva maneuver, the maximum depth is often limited to around 10–15 meters (30–50 feet) before it becomes ineffective and potentially dangerous, especially in freediving.
