The use of personal protective equipment (PPE) can increase the risk of overheating, but several strategies can reduce this risk, according to a study published in the British Journal of Sports Medicine.

• PPE creates a microclimate around the skin that reduces its capacity for heat loss. That, combined with longer shifts, can result in increased core temperature, increased sweat rates, and dehydration.

• Cooling devices worn under PPE have been shown to decrease the physiological and subjective strain in a simulated hot and humid laboratory environment.

• Two examples of cooling strategies that could be used in clinical settings are cold water/ice slurry ingestion and cooling vests.

• The type, frequency, and extent of cooling interventions can be optimized depending on the setting, PPE wear-time, physical duties and personal preferences.

• These cooling strategies can be applied prior to, during, and after working activities with PPE, but there is less evidence for the benefits of post-cooling compared with pre-cooling and cooling during activities.
