WASHINGTON — Having sex once a week can slow down the signs of ageing in women, according to new research from the University of California in San Francisco.
Researchers analysed physical intimacy, as well as partner support or conflict, overall relationship satisfaction and stress in 130 women in long-term relationships.
Telomere lengths were analysed using blood samples taken from the women and the results, published in the journal Psychoneuroendocrinology, showed that those who had sex on a weekly basis (even just once) had longer ‘caps’.
Earlier research also indicated that a good sex life was an essential for good health.
The preliminary study found that women who reported having sex with their partner during the course of the week tended to have significantly longer telomeres, the protective end caps on our DNA.
Relationship satisfaction, stress and partner support or conflict had no impact on telomere length.
Telomeres shorten with age and poor lifestyle habits, such as alcohol abuse. But being active including sexually – lengthens them.
Lead researcher Tomás Cabeza de Baca said, “over time, shortened telomeres may contribute to chronic degenerative diseases and premature mortality. Sexual intimacy may dampen the effects of stress by down-regulating stress response systems and up-regulating immune response.”
At the moment there is no evidence that sex has the same affect on me but nevertheless, we’re sure you won’t have a problem convincing your partner of the benefits.
‘Over time, these patterns of stress function should result in longer telomere length,’ PsyPost reported.Follow @gorkhapost
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.
