NEW YORK — A good night’s sleeps revives you for the day as well as gives you an extra strength in your sex life, according to a new study.

David Kalmbach from the University of Michigan Medical School has found that every extra hour of sleep improved the livelihood of sexual movement with a partner by 14 percent.

In a study of 171 women, those who obtained more sleep on a given night experienced greater sexual desire the next day.

“If you are having issues in the room, one of the things to consider is, are you sufficiently getting sleep,” Kalmbach asked in a paper that appeared in the Journal of Sexual Medicine.

Sleep was also essential for genital arousal, such that women who slept longer on average experienced fewer problems with vaginal arousal than women who obtained less sleep.

Kalmbach said his findings covered well slept women over the time.

“The impact of sleep on sexual desire and arousal has received little attention in the field, but these findings show that inadequate sleep can diminish sexual craving and arousal for women,” Kalmbach added.

Drinking 3 cups of coffee or tea daily may keep stroke risk at bay

KATHMANDU — There have been several conflicting studies on the health benefits of drinking coffee and tea and their various varieties. But drinking up to three cups of coffee or tea in a day is safe because it reduces irregular heartbeat and stroke risk, according to a new study published in the journal JACC: Clinical Electrophysiology.

Coffee has previously been believed to worsen abnormal heart rhythms, as doctors generally discourage patients suffering from the condition. However, the results of this particular study say that a daily consumption of upto 300 mg of caffeine may be safe for arrhythmic patients.

This is because the caffeine acts as a stimulant to the central nervous system and blocks the effect of adenosine. Adenosine is a chemical which causes Atrial Fibrillation (AFib).

A single cup of coffee contains about 95 mg of caffeine. It acts as a stimulant to the central nervous system and works to block the effects of adenosine — a chemical that causes AFib.

AFib is the most common heart rhythm disorder, causes the heart to beat rapidly and skip beats, and if left untreated, can cause strokes.

“There is a public perception, often based on anecdotal experience, that caffeine is a common acute trigger for heart rhythm problems,” said lead author Peter Kistler, Director at Melbourne’s Alfred Hospital.

But, “caffeinated beverages such as coffee and tea have long-term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine,” he added.

A meta-analysis of 228,465 participants showed that AFib frequency decreasing by 6 per cent in regular coffee drinkers, and an analysis of 115,993 patients showed a 13 per cent reduced risk.

Another study of 103 post-heart attack patients who received an average of 353 mg of caffeine a day showed improvement in heart rate and no significant arrhythmias — or abnormal heart rhythms, that cause the heart to beat too fast, slow or unevenly.

However, in two studies, where patients drank at least 10 cups and nine cups of coffee per day, showed an increased risk for ventricular arrhythmias (VAs) – a condition in which the lower chambers of the heart (ventricles) beat very quickly.

On the other hand, patients with pre-existing heart conditions who consumed two or more energy drinks — that contains concentrated caffeine — per day reported palpitations within 24 hours.
