In an athlete, who is very used to monitoring their pulse, it can be lower due to their superb physical condition. Any northern latitude Olympic athlete knows their resting pulse and how long it takes, after strenuous activity, to reach it. And this is a red flag for them, because it means that energetically, their chakras and aura are having a tough time adjusting to the different energy found in the southern latitudes. If this person is sensitive, it can affect them on any and all levels. It is weaker.
Breathing is labored.
Their pulse rate is slower in coming to rest. It takes them longer to recover. There is good news. Meditate about an hour before your event or competition. Meditation is well known to lower blood pressure and increase oxygenation in the body.
