By digesting fibers, Humans produce in the intestines up to 12 Liters of hydrogen per day. It is used for 80 years as breathing gas in deep sea diving. No toxicological report was ever issued. Hydrogen is FDA approved: GRAS Notice (Generally Recognized as Safe)
No, not really. The saturation level for the body is reached after about 5 min of inhalation. 1 hour after finishing inhalation, the quantity of hydrogen left in the blood is below detection levels.
Since molecular hydrogen is so absolutely tiny, it passes through any tissue, and will forever raise through concrete, tin and tiles until it escapes into outer space.
The diving gas mixture is 50% hydrogen, 2% Oxygen and 48 % Nitrogen. That is way higher then the recommended "below 4% inhalation volume" used in the graph at the end of this paragraph. They breathe this gas for days. No adverse medical effects reported. View Blood concentration levels
So a resounding NO, you can't overdose on hydrogen.
You can inhale it, drink hydrogen infused liquids and juices, apply the gas to skin, muscles and organs and spray hydrogen infused water on the skin.
If you infuse enough hydrogen in water with 30 deg. Celsius, you will reach the saturation point of 1.46 ppm in a couple of minutes.
Henrys Law defines a maximum volume of any gas that can be dissolved in water with a given pressure. Here is a diagram of the solubility of h2 in water at sea level.
At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.

There are several important pathways where hydrogen has positive effects:
There are over 170 identified conditions for humans which benefit from hydrogen exposure.
A non-complete list of common conditions:

Diseases and physiological states for which hydrogen effects are reported and classified by target organs ( NIH ): ( 15 ).
Our principal argument is the sheer volume. Compare the 1 to 4 mg hydrogen per liter in hydrogen water with 1,090 mg hydrogen in the body after a twenty-minute breathing session. A thousand times more.
The hydrogen is produced on demand, there is no tank.
The timer shuts down after the programmed time.
The HydroGen has protection against any explosion from an accidental ignition source at the end of the hoses.
It is 100% safe for breathing, with no risks of explosion in the body. This holds true for the respiration rates of children, teens, adults, and aged people. I've run the numbers and the % gas in the body is very low.
Hydrogen dissipates extremely fast and becomes non-flammable. Watch how close the person has to put the flame to the burner to ignite it. Hydrogen is not very explosive at all.
