Staying Safe During a Heatwave

As temperatures rise, heatwaves can pose serious health risks, particularly for older adults, young children, pregnant women, people with chronic health conditions, and those who work outdoors. Taking simple precautions can help prevent heat-related illnesses.

During a heatwave, staying hydrated is one of the most important protective measures. Drink water regularly throughout the day. Make sure to check on vulnerable family members, friends, or neighbours as older people and young children can become dehydrated much faster than others. Watch for warning signs such as dizziness, confusion, fatigue, or high body temperature, and seek medical advice if symptoms develop.

Overheating, heat exhaustion and heatstroke can occur rapidly, making it important to stay cool. Keep indoor spaces as comfortable as possible by blocking direct sunlight during the day and allowing fresh air to circulate when temperatures drop in the early morning or evening. If your home becomes too warm, consider spending time in air-conditioned public spaces. Older adults, people living alone or in isolation, and individuals with disabilities can register with their local council so they can be contacted and supported during periods of extreme weather or other emergencies.

If you have to go outside, try to stay in the shade, especially during the hottest part of the day, typically between 11am and 3pm. Make sure to wear suncream, a hat, sunglasses and loose and light clothing. Pay special attention when doing sports to make sure that heat, dehydration, and fatigue do not compromise your health.

Even after temperatures begin to fall, it is important to remain alert for signs of dehydration or heat exhaustion.

Diabetes Awareness Campaign – 21 May 2026

Diabetes is a chronic metabolic disease, affecting millions of people across all ages and backgrounds. It occurs when the body has trouble controlling blood sugar (glucose). This can happen when the body doesn’t produce enough insulin or can’t use it properly. Over time, high blood sugar can affect the heart, eyes, kidneys, nerves, and many other parts of the body. Types of diabetes include Type 1 Diabetes, Type 2 Diabetes, and Gestational Diabetes.

The CERN Medical Service will be present in R1 and the Main Building with interactive information stands from 11:00 to 14:30. In addition, expert talks and presentations by prevention groups will take place from 12:30 to 13:30 in B40, Salle Curie (40/S-C01).

Seasonal allergies

Seasonal allergies, often called hay fever, are a common condition that affects lots of people each year. Medically known as allergic rhinitis, they occur when the immune system overreacts to airborne allergens such as pollen from trees and grasses. Symptoms can range from mildly annoying to significantly disruptive, especially during peak allergy seasons in spring and autumn.
