Almost all runners have at some time experienced what's become called the ‘Runners High‘. This feeling is a sense of well-being and also euphoria which athletes may experience whenever running that temporarily helps them really feel a lot more tranquil and also calmer when out on a run. Runners report that the high is linked to decreased anxiousness, a heightened feeling of calm along with a lessened ability to feel discomfort. It's not something which is exclusively as a result of running and may occur in almost any cardiovascular exercise for example bicycling or going swimming. There does exist, however, quite a bit of variability between athletes in the way that they experience this and not all athletes go through it or feel it with every run. Those runners that have been running for longer tend to experience it more regularly and it is generally mainly with the lengthier runs. Running can also have long term psychological health improvements as do other kinds of regular aerobic fitness exercise which may be linked to the experience of this runners high.
A good the runners high may very well be an evolutionary issue. The theory would suggest that when our bodies release chemical substances to reduce the pain sensation that comes with elevated physical exercise when that physical exercise had been needed for looking for food and fleeing away from possible predators, then this would probably increase an individuals probability of surviving. This example of the modern-day runners high which makes running more gratifying may have been a thing that evolved to serve as a incentive which kept early humans hunting wildlife and gathering food with regard to their survival.
The actual physiology underpinning what could cause the runners high is not that straightforward. There are a variety of chemicals that are higher during exercise which will be the reason for the physiology. The favourite thinking is that it was that its due to higher release of endorphins that act similarly to morphine, however there's not as much support for this hypothesis now as endorphins don't pass the blood-brain barrier to have an effect there. Endorphins still do have an effect on the muscular tissues to regulate pain feelings. New studies have implied the mechanism could be via the increased release of chemical substances referred to as endocannabinoids which are just like cannabis or marijuana which may lower pain and improve feelings. As opposed to the endorphins, endocannabinoids can cross the blood-brain barrier. There is some new interest in the function of the hormone, leptin, that regulates the feelings of being hungry. Research shows that mice with less leptin would run considerably more than mice that have average amounts. The authors of that study report that this might be for the reason that mice which may have less leptin ended up more prone to feel the experience of the ‘runners high’. They correlated this to the evolutionary theory by indicating that a drop in leptin levels increases enthusiasm for physical activity via the incentive of the ‘runners high’ as a way to improve the incentive for the search for foods in order to survive.
The simplest way to experience a runners high would be to exercise more regularly and run over an hour or so daily. It can come along with running these longer distances.
