Tips on How to Avoid Heat Stroke
During the summer season in different parts of the world temperature can get really extreme and this is referred to as a heat wave. Heat wave by definition means hot weather that may be accompanied by high humidity. Prolonged exposure to this condition may have undesirable effects in our body like heat stroke that may lead to disability or even death. List below are some tips to avoid heat stroke:
1. If you’re going out under the sun be sure to put some sunscreen of at least SPF 50. Wear cotton long sleeve shirt to protect your arms also. Wearing a cap is also a good idea to protect your head from the heat.
2. Always drink lots of fluid wherever you go. Drinking coffee and alcohol doesn’t help, it only dehydrates your body further. Water is still the best liquid to rehydrate your body. Be careful in drinking sports drink as most of them contain lots of sugar. It is advisable to drink one glass of water every hour or if you’re sweating a lot, two glasses of water would be better.
3. Always bring an umbrella or a big hat. Always try to have a rest in a shade, it can be waiting-shade, a building or under a tree. Try to relax and have a rest whenever you are feeling extreme heat.
4. Know when extreme temperature occurs, in most parts of the world it is usually between late morning until early afternoon or 10 AM until 3 PM. As much as possible avoid going out during this period. If you’re planning to go out jogging it’s better to do it early in the morning, as early as 5AM or late in the afternoon when the sun is already setting. Going to the malls is no problem since most of them have centralized air conditioning system.
5. Eat a light meal, it is advisable to have a light stomach during the hot season to help process our food easily. If you’re going out, be sure to eat lightly. Excess fat in our food causes more heat in our body and may cause difficulty in accomplishing work. It may also cause dizziness and nausea. If you’re going out, have at least a half hour rest after eating.

Stroke – Definition, Causes, Symptoms and Treatment
Stroke is a disease that affects the blood vessels that supply blood to the brain. Without blood to supply oxygen and nutrients and to remove waste products, brain cells quickly begin to die. Stroke is sometimes called a “brain attack. Stroke is a medical emergency and can cause permanent neurological damage or even death if not promptly diagnosed and treated. It is the third leading cause of death and the leading cause of adult disability in the United States and industrialized European nations. Stroke is the third leading cause of death in the United States and the leading cause of disability. Stroke kills about 150, 000 Americans each year, or almost one out of three stroke victims. Strokes affect blacks more often than whites, and are more likely to be fatal among blacks. Men have more strokes than women. But, women have a risk of stroke during pregnancy and the weeks immediately after pregnancy. The cause of stroke is an interruption in the blood supply, with a resulting depletion of oxygen and glucose in the affected area. This immediately reduces or abolishes neuronal function, and also initiates an ischemic cascade which causes neurons to die or be seriously damaged, further impairing brain function. Risk factors for stroke include advanced age, hypertension (high blood pressure), previous stroke or TIA (transient ischaemic attack), diabetes mellitus, high cholesterol, cigarette smoking, atrial fibrillation, migraine with aura, and thrombophilia. Practice blood pressure is the most important modifiable risk factor of stroke.
Many other risk factors, such as cigarette smoking cessation and treatment of atrial fibrillation with anticoagulant drugs, are important. There are two main types of stroke. One (ischemic stroke) is caused by blockage of a blood vessel. Usually this type of stroke results from clogged arteries, a condition called atherosclerosis. Fatty deposits collect on the wall of the arteries, forming a sticky substance called plaque. Other (hemorrhagic stroke) is caused by bleeding. Bleeding strokes have a much higher fatality rate than strokes caused by clots. Some people have defects in the blood vessels of the brain that make this more likely. The flow of blood after the blood vessel ruptures damages brain cells. Hemorrhage (or bleeding) from an artery in the brain can be caused by a head injury or a burst aneurysm. Aneurysms are blood-filled pouches that balloon out from weak spots in the artery wall. They’re often caused or made worse by high blood pressure. Aneurysms aren’t always dangerous, but if one bursts in the brain, they cause a hemorrhagic stroke.Symptoms of a stroke include sudden numbness or weakness, especially on one side of the body; sudden confusion or trouble speaking or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble with walking, dizziness, or loss of balance or coordination and sudden severe headache.
