Is sky-diving forbidden since it might be considered a risk to once life and is not a necessary activity (like e.g., driving a car would be)?

The Torah says (Dvarim 4:15) "guard your souls" and elsewhere (Dvarim 22:8) commands us to "make a guardrail on your roof".

Does that prevent us from engaging in dangerous sports? (assume for the purpose of this question that there is a small but real risk in sky-diving).

  • Does this mean that if driving a car is shown to be more life threatening to sky diving, we shouldn't drive?

    From your comment here it sounds as though an important part of your question is something along the lines of "and skydiving is not necessary for general life activities like e.g. driving a car is". If that's the case then I suggest you edit that in to your question so you don't get answers like "we see that things with a slight risk are okay because R. Moshe Feinstein took a car to a wedding".

    @Aaron (1.) Driving is something normally done by the public in the course of their routine ("דש ביה רבים"), so it may be in a more permissible halachic category. (2.) Choosing 10,000 (passenger?) miles is arbitrary. Any given car trip is more likely to be closer to 10 miles (decreasing the relative risk by a factor of 1,000), in which case a skydive would be about 50 times more dangerous. (3.) Did you check if 21 is a standard fatality count, and not from an abnormally safe year? (4.) Does the "3 million jumps" include military jumps, usually made by trained personnel (which alters the risk)?

    @Aaron (1.) wouldn't include military jumps. Did you see this specified somewhere? Because otherwise, I'd be wary (not yet having researched the topic myself) that the United States Parachuting Association may have a vested interest and may have included that data to portray the risk more favorably. (2.) Would the lifetime risk be halachically lumped like that, or would each event be halachically assessed separately? (I'm not necessarily saying one way or the other, but it's a non-trivial point).

1 Answer 1


This question is related to and emerged from a comment by the OP on whether plastic surgery was allowed. I think the question of which parameters allow us to engage in action/dangerous sports has merit. We can all agree that some sports (e.g., Formula 1 racing, sky-diving, boxing) are more dangerous than others, and as mentioned in a comment are not necessities.

So to what extent is a Jew allowed to engage in such activities?

There is no clear cut ruling on the topic but it emerges that it is generally prohibited to put oneself at risk without a good reason (e.g., earning a living) although the parameters of this risk are not clearly defined

The basic sources are

The Rambam has two lists of dangerous things, Hilkhot Deot 4.1 has unhealthy, discouraged but ultimately permitted activities, Hilchot Rotzeach Ushemirat HaNefesh 11:5 has dangerous and forbidden things. The Tzitz Eliezer (15:39) understands the difference to be based on their degree of danger. See Chaim Jachter in Gray Matter (vol 3, p. 18) where he writes based on this that Halacha allowed reasonable members of society to define the parameters of the prohibition to engage in risky activities; Halacha permits activities that people judge to be a tolerable risk based on the idea that Hashem protects the fools.

Now this is all relative. Here is how some poskim have applied these guidelines (sources here and here)

  • R Moshe Tendler (Beit Yitzchak 15:71) explains this Gemara as teaching that the Halacha defines the parameters of acceptable risky activities by what the members of a society accept as reasonable

  • R Chaim Ozer Grodzinsky (Teshuvot Achiezer 1:23) applies this guideline only when the danger is minimal and disaster rarely occurs

  • R Yaakov Ettlinger (Teshuvot Binyan Tzion 1:137, 19th century) explores the permissibility of embarking on a sea voyage or a journey across a desert. He distinguishes between an immediate danger and a long-term danger. Immediate danger is prohibited in all situations. Future danger may be ignored if it can reasonably be expected to cause no harm. It is likely that such risk is tolerated only if for the purpose of earning a living or other great need.

  • Noda B’Yehuda (II, Y.D. 10) rules that a person who is needy may enter into a situation of danger if it is necessary as part of his efforts to earn a living. However, anyone who acts irresponsibly and suspends himself from trees or engages in risky behavior needlessly is in violation of the Torah’s directive “Be exceedingly careful to guard your lives"

  • Chazon Ish writes that it does not seem that this Gemara is offering any extension to permit entering into danger. Rather, the Gemara is dealing with a case of climbing on a tree or crossing a ramp. These behaviors are potentially dangerous, but when a person does them he usually does so cautiously and with protecting himself with taking proper safety measures. This is true whether the person is involved in earning a living or not. The reason this is permitted is that when a person proceeds carefully, the risk of danger is limited. This is permitted for anyone who acts in this manner, but outright placing oneself in dangerous conditions remain prohibited.

Here is how Daniel Eisenberg at Aish summarizes it

The Talmud asks in several places why certain potentially dangerous actions are permitted. It answers that a person need not avoid small risks that are accepted by the rest of normal society without undue concern.

For instance, since automobile travel presents an element of danger, we might think that it should be forbidden. Nevertheless, it is a risk accepted by society and most people do not give much thought to the danger. Therefore, driving with normal caution (such as wearing a seatbelt and using the turn signal) is permitted by Jewish law, despite the inherent small risk.

The rationale for this ruling is that while we may not take indiscriminate risks, we may go about normal activities of daily living with the guarantee of heavenly protection. This is derived from the book of Psalms that states: "God watches over the simple." That is, I do not have to worry when I go outside that I may be the one in a million to be struck by lightning. Because I can rely on the promise that God watches over me -- as I do the simple activities of daily living.

    I have personally asked this question to Rav Dovid Cohen, and he ruled it was forbidden for this very reason, along the same lines of logic that Daniel Eisenberg gave.
