Time confirmed when Mayo Status Yellow high temperature warning comes into effect

A Status Yellow high temperature warning has been issued by Met Éireann and will be in effect in Mayo from 12 noon tomorrow (Tuesday) until 9 a.m. on Friday.

Expected temperatures in excess of 27 degrees and night time temperatures in excess of 15 degrees can cause heat stress and uncomfortable sleeping conditions.

Who is most at risk?

Heatwaves can affect any of us, but those most at risk include:

* Babies and young children

* People over 65

* People with underlying health conditions including problems with breathing, heart, kidneys and diabetes

* People with Alzheimer’s and dementia

* People who spend a lot of time outside or in hot places (such as those who work outdoors or the homeless)

Tips for keeping cool in hot weather

When inside you should:

Turn off lights and appliances not in use as they generate heat

Close windows that face the sun during the day, and open them at night when the temperature drops

Close curtains in rooms that get morning or afternoon sun

Sprinkle water over your skin, or keep a damp cloth on the back of your neck

Use an electric fan (but only if the temperature is below 35 degrees)

When outside you should:

Avoid going out during the hottest part of the day if possible (11am to 3pm)

Wear light and loose-fitting clothing that covers your skin

Wear a wide brimmed hat and sunglasses

Regularly apply a broad-spectrum (UVA and UVB) water-resistant sunscreen to skin that is not covered, using factor 30+ for adults and 50+ for children

Stay in the shade.

Drink plenty of fluids

Adults need about 2 litres of water over 24 hours (may be less for smaller people or those with medical conditions)

Drink more fluids when you feel any dehydration symptoms. The best fluids to drink are water or oral rehydration sachets (ask your pharmacist about how to use these safely)

Drink enough during the day so your urine (pee) is a pale clear colour

Helping a person under your care drink enough

A person you're caring for may not have a sense of how much they're drinking.

You can help them by:

Making sure they drink during mealtimes

Make drinking a social thing, like 'having a cup of tea'

Offer food with a high water content such as ice cream, jelly, fruits like melon

Health advice for health and care professionals

Service providers with a duty of care to their clients, as well as those working with vulnerable groups, need to be aware of the effects and increased demands that come with a heatwave.

When to get medical help

Heat exhaustion and heatstroke

Heat exhaustion is not usually serious if you can cool down within 30 minutes. If it turns into heatstroke, it needs to be treated as an emergency.

Dehydration

Dehydration means that your body does not have enough fluid.

If it's not treated, it can become a serious problem.
