This signal appears to indicate to a diving buddy that you have become ill while underwater. While it is true that until now, when a diver felt unwell, they could simply cancel the dive or indicate that something was not going well, these were somewhat ambiguous signals, which did not fully explain what was happening at that moment. To better communicate a health issue like this while diving, the hand signal meaning, “I don't feel well,” has become a new standard signal to teach in courses. To make the signal, the diver's hand, with fingers toward himself, "draws" an oval to include his head and torso, indicating that something is wrong with him (not his equipment).

Open Water Course: The language of gestures, diving signals, is used to communicate when diving. The best-known signal is the OK sign, where a circle is formed with the thumb and index finger and the other fingers point upward. This signal can be used either asking or affirmative. To indicate that something is wrong the fingers are extended and the palm is down and waving. Using your thumb you indicate whether you want to go up (thumbs up) or down (thumbs down). The following video shows the most used diving signals. Although most of the signals are known internationally, it is advisable to analyze the most important signals with your partner before diving in.

I'm not feeling well, new sign

Esta señal aparece para indicar a un compañero/a de buceo que has enfermado estando debajo del agua. Si bien es cierto que hasta ahora, cuando un submarinista se encontraba mal, se podía simplemente cancelar la inmersión o indicar que algo no iba bien, eran señales un poco ambiguas, que no explicaban del todo lo que sucedía en ese momento. Para comunicar mejor un problema de salud como este durante el buceo, la señal manual que significa, «No me siento bien», se ha convertido en una nueva señal estándar para enseñar en los cursos. Para hacer la señal, la mano del buceador, con los dedos hacia sí mismo, «dibuja» un óvalo para incluir su cabeza y torso, lo que indica que algo está mal con él (no con su equipo)

What you need to remember is that every 10 meters the water pressure increases by approximately 1 bar. At 10 meters deep it has a pressure of 2 bar (the atmosphere also presses with 1 bar!). This total pressure is also called absolute pressure. In the first meters underwater the differences are relatively the greatest. Below is a useful table.
