Is there a professional secret for enduring long 3-6 hour freediving and spearfishing sessions?


The effects of dehydration and low energy stores (glycogen) in the body are radical at worst and limiting at best.

We all may be aware of the snickers-style (H)angries that occur when we don’t have enough fuel in the body and start to become irritable and think irrationally.

Imagine experiencing that in the ocean and at 15m deep? Not ideal. What about fluid loss and how our brain functions when dehydrated though?

According to the National Centre for Biotechnology Information article entitled, Dehydration affects brain structure and function in healthy adolescents, “…dehydration causes shrinkage of brain tissue and an associated increase in ventricular volume”, and “given the limited availability of brain metabolic resources, these findings suggest that prolonged states of reduced water intake may adversely impact executive functions such as planning and visuo-spatial processing”. Additionally, indications were found that a higher level of brain activity is required to perform the same tasks as compared to being adequately hydrated.

What impact does this have on breath-hold? Well, as we have a limited one lungful of air, it means that the finite oxygen stores we have are going to be used more quickly when we are dehydrated as compared to normal levels. This means either shorter breath-hold times for the same result, or worse, the same length breath-hold and poor decisions, poor spatial awareness and increased probability of getting into trouble. If you can’t think straight or plan, don’t dive!

What’s the solution?

The obvious one is to take fresh water for drinking whilst you’re out in the ocean, sea or lake. However, due to the other side effects of breath-hold, i.e. increased urine production and secretion, we’re also losing essential salts and minerals which take more than fresh water to restore.

The other thing we avoid as breath-hold divers is eating before freediving or spearfishing, that feeling of a full stomach does nothing to help taking a deep diaphragmatic breath. There’s no point packing a sandwich or anything too solid, it’ll be horrible to digest.
