What is a good practice to follow when diving in colder waters?

Monitoring air consumption closely is essential when diving in colder waters due to the physiological effects that cold temperatures can have on the body and the diver's equipment. Cold water can lead to increased air consumption as it may cause stress and anxiety, which can result in more rapid breathing. Additionally, cold conditions can necessitate a higher level of awareness regarding the situation, leading divers to manage their air supply more diligently.

In colder environments, other factors such as thermal protection and potential increases in buoyancy due to the insulated wetsuit or drysuit might affect how divers experience their dive. Therefore, paying close attention to air consumption helps ensure that divers maintain a safe reserve and avoid running low on air unexpectedly. This practice is crucial for upholding safety protocols and enhancing overall dive planning in colder water environments.
