Women are more prone to emotional stress than men

A new study has revealed that women are more sensitive to the key stress hormone, corticotropin releasing factor (CRF), which helps control the body’s reaction to stress.

Research found that, whilst women are extremely affected by even small amounts of CRF, men are relatively immune to even large amounts of the hormone. Scientists injected rats with CRF and found that the hormone bound more tightly to brain cell proteins in female rats, making them more sensitive to its effects.

The male rats, however, were able to reduce the levels of protein, stopping the hormone from binding and therefore reducing its effects on the brain.

Lose more weight when you workout with a friend

On average, women lose an amazing ten pounds when they agree to train with a friend, as opposed to those who go it alone. Researchers studied a group of 3,000 women and found that 61°/ found it almost impossible to summon up the energy to exercise on their own.
However the same proportion of these women said they enjoy going for a jog or a swim with a friend and admit that they push themselves harder if they have someone with them.

Does coffee in the morning wake you up?

Morning coffee
If your day doesn’t officially start until that first sip of coffee in the morning, it may surprise you to hear that caffeine has no effect on waking up regular coffee drinkers.
A new study on 379 volunteers, found no difference in alertness between coffee fiends and their non-caffeine drinking counterparts.
‘Although frequent consumers feel alerted by caffeine, especially by their morning tea, coffee or other caffeine-containing drink, evidence suggests that this is actually merely the reversal of fatiguing effects of acute caffeine withdrawal,’ said Peter Rogers from the University of Bristol, who led the study. However, scientists recommend continuing in your caffeine habits whatever these may be, to avoid suffering withdrawal symptoms.
