Winter can be divided into wet and dry winter. Wet or early winter is characterized by fall in temperature along with high humidity. Environmentally, we see fog and smog during this season. Dry or late winter on the other hand is characterized by absence of fog, smog and presence of chilly airy winds.
Most hypothermia illnesses occur in dry late winter. The transition phase between wet and dry winter is on the day of Lohri. In terms of Ayurveda, this means shifting from Kapha to Vata atmosphere. The onset of dry winter is also the time for accelerated movement disorders in the body. Accelerated hypertension, arrhythmias, paroxysmal atrial tachycardia, brain hemorrhage, heart attack etc. all occur when dry late winter starts.
The correct lifestyle in this season has been defined in Ayurveda and it involves reducing consumption of stringent, bitter and pungent foods

Energy Drinks May Put Heart at Risk for Sudden Death

Energy drinks may raise blood pressure and prolong QT interval increasing the risk of sudden cardiac death. In a meta-analysis by Sachin A. Shah at University of the Pacific in Stockton, Calif, with a pooled analysis of 93 people who consumed energy drinks, the QT interval on an ECG was significantly prolonged by 10 ms. The threshold level of regulatory concern is around 5 ms. In another pooled analysis of 132 people by the same group, researchers found a significant increase in systolic blood pressure by 3.5 mmHg that was associated with the consumption of energy drinks. Doctors are generally concerned if patients experience an additional 30 ms in their QT interval from baseline. QT prolongation is associated with life-threatening arrhythmias. Most energy drinks have caffeine. Drinks such as Monster, Red Bull, Rockstar, Full Throttle and AMP have three times the amount of caffeine as colas. A 16-oz. can of Monster Energy, for example, contains 160 mg of caffeine, which is almost as much as 5 cans of soda.
