Women and men are different in more than the obvious ways. A woman is more likely to feel light-headed after one glass of wine, while a man is perfectly fine. A woman wants to talk about her bad day, while her boyfriend is content going to gym and sweating it out. So what’s the deal behind these differences? It’s down to science.

• So, let’s look at the effects of drinking in women and men. It turns out drinking is more toxic to a woman’s body and that’s why they feel the effects of alcohol more quickly. Basically, women hold less water in their bodies. This means they have a higher concentration of alcohol in their blood after drinking than a man does.
• So, why is easier for a man to lose weight than a woman? Because men have more testosterone, which means they’re built with more muscle and less fat. One pound of muscle burns 70% more calories than one pound of fat. For example, if both a man and a woman had a body mass index of 27 – which is just in the overweight range - it would take the man about 23 days to lose 5 pounds, but it would take the woman 45 days.
• Quitting smoking is also harder for a woman. According to the Institute for Women's Health Research, women have more severe withdrawal symptoms when they try to quit smoking. Women also don't respond as well to nicotine replacement options - like nicotine patches. Researchers aren't exactly sure why - but they say there are differences in a woman's brain when it comes to addiction and breaking addiction.
• You probably know that women and men handle stress differently too – and that’s down to hormones. Women have more oxytocin in their bodies than men, that’s a feel good, bonding hormone. Experts say that this hormone makes women want to talk about their problems. On the other hand men have smaller amounts of oxytocin and that makes them take the fight or flight approach when it comes to stressful situations. So a woman may call a friend to vent after a stressful day – and a guy may flee to the gym.
