Being active in hot and humid conditions poses special concerns. Heat stress and resulting heat illness is a concern in these conditions. Although deaths from heat illness are rare, exertional heat stroke is the third-leading cause of on-the-field sudden death in athletes. Intense exercise, hot and humid weather and dehydration can seriously compromise athlete performance and increase the risk of exertional heat injury. The risk of sudden death is highest when athletes begin any new practice period, especially within the first few days. And sport injuries can be three times higher during the preseason than in the regular-season practice periods. Conditioning sessions are also a higher risk activity than the normal sport drills and skills sessions. Constant surveillance and education are necessary to prevent heat-related problems.
