Cold weather can place additional physical stress on the body. Conditions like hypothermia, in which an individual’s body falls below 95 degrees Fahrenheit leading to a lack of coordination and mental confusion, can strike outdoor sports enthusiasts or athletes unexpectedly.
Those with heart disease are particularly at risk for health complications from the cold – especially those with coronary heart disease who are more likely to suffer chest pain in the cold weather. Some studies have suggested that winter weather and exertion in the chill can raise a person’s risk of heart attack.
If you plan on spending a lot of time outdoors it’s recommended that you avoid sudden exertion and dress warmly and appropriately.
