Top tips on how to stay safe in a heat wave

With warm temperatures expected to continue this week, Jane Walker a home health specialist from Home Detail has shared some some essential tips to help you stay safe and enjoy the sunshine.

Stay hydrated

Dehydration is a risk during hot weather. Make sure to drink plenty of water throughout the day, even if you don't feel thirsty. Avoid excessive alcohol and caffeinated beverages, as they can contribute to dehydration.

Protect your skin

Sunburn not only causes immediate discomfort but also increases the risk of skin cancer. Apply sunscreen with a high SPF regularly, wear protective clothing (including hats and sunglasses), and seek shade during peak sunlight hours (generally between 10 am and 4 pm).

Keep your home cool

If possible, use fans or air conditioning to keep indoor temperatures cooler. Close curtains or blinds during the hottest part of the day to block out direct sunlight and consider creating a cool area in your home it gets too hot.

Dress appropriately

Wear lightweight, loose-fitting clothing made from breathable fabrics such as cotton. Light colours reflect sunlight and can help keep you cooler than dark colours.

Look out for vulnerable individuals

The elderly, young children, and people with chronic health conditions, are more vulnerable to heat-related illnesses. Check on them regularly and ensure they are staying cool and hydrated.

Avoid strenuous activities

If possible, schedule outdoor activities during the cooler parts of the day, such as early morning or late evening. If you must exercise or work outdoors, take frequent breaks in shaded or cool areas and listen to your body's signals.

Know the signs of heat exhaustion and heatstroke

Heat exhaustion and heatstroke are serious conditions that require immediate attention. Symptoms can include: dizziness, nausea, rapid heartbeat, confusion, and hot, dry skin (heatstroke) or heavy sweating (heat exhaustion). If you or someone else experiences these symptoms, move to a cool place, hydrate, and seek medical help if necessary.
