When not to go scuba diving?
A person with heart trouble, a current cold or congestion or who has epilepsy, asthma, a serious medical problem, or who is under the influence of alcohol or drugs, should not dive. The most important rule in scuba diving is to always breathe continuously and never hold your breath to avoid lung over-expansion injuries. Another important rule is that divers should ascend slowly and safely to prevent decompression sickness.Before a dive (including the night before), it’s best not to drink heavily, use recreational drugs, or even gorge on heavy, greasy foods. Diving is a pretty athletic activity, so we want to make sure we’re not sick to our stomach or lagging in our cognitive abilities while on the boat and underwater.The first rule of scuba diving is to breathe continuously and never hold your breath. The effects of water pressure mean the air inside your lungs expands when you ascend, and not releasing it can cause lung injuries.Pain Relievers It thins your blood, which isn’t dangerous under normal circumstances, but if you have an embolism or other accident that causes profuse bleeding, you could lose significantly more blood than normal. Other than that, there’s not much to worry about when taking pain meds while diving.
What is the 1/3 rule in scuba diving?
In technical diving, the 1/3 Rule ensures divers have enough gas for the descent, return, and emergencies. It divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve, enhancing safety in challenging environments. Divided Gas Supply: The 1/3 rule divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve. Emergency Preparedness: The reserved third ensures that divers have enough gas to manage unexpected situations or emergencies.The Rule of Thirds is a guideline used by scuba divers to manage their air supply effectively throughout a dive. It involves mentally dividing one’s breathing gas supply into three equal parts. One-third for the outward journey, one-third for the return journey, and one-third as a reserve or emergency supply.In technical diving, the 1/3 Rule ensures divers have enough gas for the descent, return, and emergencies. It divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve, enhancing safety in challenging environments.For divers following the rule, one third of the gas supply is planned for the outward journey, one third is for the return journey and one third is a safety reserve.
What is the 120 rule in scuba diving?
Here’s how it works: Your max depth (in feet) + your bottom time (in minutes) should be less than or equal to 120. That’s it. So if you plan to dive to 60 feet, the rule says you shouldn’t stay down longer than 60 minutes. A safety stop, usually done for three minutes at about five meters or fifteen feet, gives your body that extra time to release nitrogen absorbed during your dive. This simple pause helps reduce the risk of decompression sickness and allows your body to adjust gently before surfacing.
