Relax the dress code during heatwaves

← Back to Cool Tips Pro Employee Wellbeing

A full suit or formal outfit adds an extra layer that traps body heat. Temporarily relaxing the dress code during heat peaks — lighter clothing, no tie, short sleeves — is a simple gesture that directly improves your team's comfort.

Dark, thick, or tight clothing traps body heat and limits sweat evaporation, which is the body's main natural cooling mechanism. Light, loose, pale-colored clothing lets air circulate and supports that natural cooling.

• Immediately improves perceived thermal comfort
• No cost to the company
• Shows concrete attention to employee wellbeing
• Easy to communicate and implement overnight

1. Clearly define the trigger threshold (e.g. a heat alert) and its duration
2. Communicate the new rules clearly to the whole company
3. Set any needed limits (e.g. keeping presentable dress for client-facing roles)
4. Return to the usual dress code once the alert is lifted
