Hot bath and alcohol might cause death - updated

If you drink alcohol, do not take a hot bath or soak in a hot tub nor drinking alcohol in hot tub is a good idea. Both might get you killed.

Alcohol causes dehydration, meaning, you lose a lot water when under the influence of alcohol.

When you are in hot water, sweating dehydrates you, same as alcohol.

High body temperature
Alcohol expands your blood vessels, causing your body temperature to rise. This goes the same when you are in the hot tub.

Heat exhaustion
Dehydration and high temperature will lead to heat exhaustion.

Signs and symptoms of heat exhaustion:
  • confusion
  • dizziness
  • fainting
  • unconsciousness
  • headache (mainly due to dehydration)
  • nausea
  • sweating

All the above can lead to palpitations, coma or death (when one drowns in the tub or hits something should one fall because of dizziness or unconscious).

Scientist explains why backpacks do NOT harm your child's back even if they're heavy

At the start of each school year, millions of parents buy their children new backpacks as they are constantly worried that not choosing the right bag could leave their kids with long-term back or spinal pain.

But Dr Michael Holmes, of Brock University in Ontario, Canada, says parents do not need to buy into the hype because there is no evidence that backpacks can cause back pain or damage to the spine.

He says that as long as parents teach children to wear their knapsacks properly with both straps, then the weight is distributed equally and their backs would not be harmed.

However, Dr Holmes does recommend choosing a traditional backpack over a shoulder bag, a cross-body bag, or a messenger bag,

These bags constantly put pressure on muscles, tissues and nerves found in the shoulder, causing pain in the neck, shoulders and upper back. Because most people carry their bags on the same side, the strain is not equally distributed.


'Life changing' asthma treatment that burns away muscle in airways

People with asthma are particularly sensitive to airborne particles and allergens which can trigger the inflammation and constriction of the muscles in the throat, causing coughing and difficulty breathing.

Bronchial thermoplasty uses radio-frequency energy to release short pulses of heat which reduce the smooth muscle mass rings the airways – lessening their ability to constrict.

A tube is inserted down the throat and the probe is guided into the entrance of the bronchi which take air into the lungs. At each entry point heat is applied which removes around 50% of the muscle mass, this is repeated about 30 times at each accessible airway – the process takes about 35 to 45 minute for one lobe of the lung.

Patients reported 34% fewer severe asthma attack and 84% A&E visits in one clinical trial.


1.4 billion risk disease from lack of exercise: WHO

More than 1.4 billion adults are putting themselves at heightened risk of deadly diseases by not getting enough exercise, doctors are warning, with global activity levels virtually unchanged in nearly two decades.

With richer nations enjoying an increasingly comfortable, sedentary lifestyle, a study by the World Health Organization said a third of women and a quarter of men worldwide are in the firing line for killer conditions such as heart disease, diabetes and cancer unless they up their physical activity.

"Insufficient physical activity is a leading risk factor for non-communicable diseases, and has a negative effect on mental health and quality of life," said the study of world exercise levels published Wednesday by The Lancet Global Health Journal.

The WHO recommends each adult do at least 150 minutes "moderate-intensity" exercise -- such as brisk walking, swimming or gentle cycling -- each week, or 75 minutes "vigorous-intensity" activity -- such as running or team sports.

The traditional Chinese medicine, which has been used for more than 400 years, contains an extract that causes obese mice to eat less and consequently lose weight, a study found.

Lead author Dr Paul Pfluger, from the German Center for Diabetes Research, said: 'We observed an average loss of about 10 per cent in body weight within one week.'

The extract, known as celastrol, is thought to create feelings of fullness by regulating the hormone leptin, which controls appetite.
