As we step into 立夏 (The Beginning of Summer, 7th solar term）on 5 May 2025, the hot weather is approaching us, and this puts outdoor workers at risk of developing heat exhaustion and in serious cases heatstroke.  This safety visit aims to equip safety professionals with effective, technology-enabled strategies to safeguard workers against heat stress and enhance occupational safety.  

Key topics include:

•	Wearable devices are gaining popularity in the fields of health monitoring, diagnosis, and drug delivery.  For example, you may have come across with a device that measures interstitial fluid glucose levels in people with diabetes; which is an alternative to routine finger-prick blood glucose testing,  We will introduce a skin-like wearable microfluidic solution that can non-invasively measure sweat biomarkers, skin temperature health, and physical activity in real time; all of this data provides feedback to the wearer to replenish their sweat loss and alert safety managers.
•	SOSM, salivary osmolarity, is a method used to assess hydration levels by measuring the concentration of electrolytes and other particles in saliva.  Studies suggest that SOSM spot checks provide a more accurate reflection of hydration status in workers and athletes.  
•	OSHA guidelines recommend that workers consume fluids regularly and replace lost electrolytes, especially during prolonged sweating.  We will differentiate the difference between an isotonic drink and a hypotonic drink.  While isotonic drinks are widely heard of, especially for athletes who train outdoors, hypotonic drinks could be an alternative if workers need rapid hydration without excess carbohydrates. 
•	While there are new anti-heat-stress fabrics and fan-cooled knitwear, phase change material (PCM) garments are designed to help regulate body temperature by using materials that absorb and release heat as they transition between solid and liquid states. These garments are particularly useful for workers in extreme heat environments, athletes, and individuals exposed to high temperatures.
•	Opportunity for participants to trial these innovative heat-stress and workplace safety solutions and discuss any related questions.
