Conditions related to feeling tired or exhausted
Altitude sickness
Altitude sickness, also known as acute mountain sickness (AMS), can occur when you ascend to high altitudes too quickly. Symptoms typically begin to appear at elevations above 2,500 metres (8,200 feet) and may include headaches, nausea, dizziness, fatigue, and difficulty sleeping. In more severe cases, it can lead to high altitude pulmonary oedema (HAPE) or high altitude cerebral oedema (HACE), both of which are serious conditions. To treat altitude sickness, the most effective approach is to descend to a lower altitude as soon as possible. Staying hydrated and resting can also help alleviate mild symptoms. Over-the-counter pain relievers may provide relief from headaches, while anti-nausea medications can assist with feelings of sickness. Preventing altitude sickness is mainly about acclimatisation. Gradually ascending to higher altitudes allows your body to adjust. It’s recommended to increase your altitude by no more than 300 to 500 metres (1,000 to 1,600 feet) per day, and to spend an extra day at higher altitudes if you start feeling unwell. Staying well-hydrated and avoiding alcohol can also reduce the risk of developing altitude sickness.
Flu
Flu, or influenza, is a viral infection that affects the respiratory system. Common symptoms of flu include a high fever, chills, muscle aches, fatigue, sore throat, runny or stuffy nose, and cough. Some individuals may also experience headaches and gastrointestinal issues, such as nausea or diarrhoea. For self-care, it’s important to rest and stay hydrated. Over-the-counter medications can help relieve symptoms like fever and aches. Be sure to use paracetamol or ibuprofen as directed on the packaging. Staying warm and drinking plenty of fluids can also aid recovery. You should seek medical assistance if you experience severe symptoms, such as difficulty breathing, chest pain, confusion, or if your symptoms worsen or do not improve after a few days. Vulnerable groups, including elderly individuals, young children, and those with underlying health conditions, should consult a healthcare professional promptly if they suspect they have the flu.
