It is not recommended to wear contact lenses while freediving. The pressure changes that occur when diving deep underwater can cause discomfort and potential damage to the eyes if wearing contact lenses. Additionally, there is a risk of losing the lenses in the water, which can be dangerous for both the wearer and the marine environment. It is best to consult with an eye care professional for advice on the safest options for vision correction while freediving. **

Packing air while freediving can be both dangerous and beneficial, depending on how it is done. When done incorrectly or excessively, packing air can lead to overexpansion of the lungs, which can cause lung barotrauma or arterial gas embolism, both of which are serious and potentially life-threatening conditions. However, when done properly and in moderation, packing air can increase lung volume and improve breath-holding capacity, allowing freedivers to stay underwater for longer periods of time. It is important for freedivers to receive proper training and guidance on how to safely and effectively pack air to minimize the risks associated with this technique. **

To dive in a swimming pool, start by standing at the edge of the pool with your toes pointing towards the water. Take a deep breath, bend your knees, and push off with your feet, extending your arms above your head as you dive forward. Keep your body straight and streamlined as you enter the water, aiming to enter at a slight angle to avoid hitting the bottom of the pool. Practice proper diving technique to ensure a safe and smooth entry into the water. **

A neck weight in freediving or apnea diving typically weighs between 1-3 kilograms (2.2-6.6 pounds). The purpose of the neck weight is to help the diver achieve neutral buoyancy in the water, allowing them to descend and ascend more easily without expending excess energy. The weight is positioned around the neck to help the diver maintain a streamlined body position and reduce the effort required to equalize the ears. The specific weight used can vary depending on the individual diver's body composition and diving conditions. **

Yes, women also pee in the water at swimming pools or beaches. While it may not be openly discussed, it is a common occurrence due to the inconvenience of leaving the water to use the restroom. However, it is important to note that peeing in the water can introduce bacteria and contaminants, affecting the water quality and potentially posing health risks to other swimmers. It is always best to use the restroom facilities provided. **

It ultimately depends on personal preference and comfort. Some people may prefer a bikini for tanning and ease of movement, while others may feel more comfortable and secure in a one-piece swimsuit. As for the swimming pool or beach, it also depends on individual preferences. Some may enjoy the convenience and cleanliness of a swimming pool, while others may prefer the natural beauty and waves of the beach. **

As an AI, I don't have the ability to physically dive for rings in a swimming pool. However, I can understand that diving for rings can be a fun and challenging activity for those who enjoy swimming and diving. It can also be a great way to improve swimming skills and breath control. **

Yes, it is bad to pee in the water at the beach or in the swimming pool. Urine contains bacteria and other waste products that can contaminate the water and pose a health risk to others. In addition, peeing in the water can contribute to the growth of algae and other harmful microorganisms. It is important to use the designated restroom facilities to avoid polluting the water and to maintain a clean and safe environment for everyone. **
