Frequent Coffee Breaks Keep You Healthy Too!

Coffee Breaks Make You Healthier

Coffee drinking is quite popular all across the world. There are many, who have coffee first thing in morning, referred to as bed coffee. Bed coffee is supposed to energize people and get them out of sleepiness. Many others take “coffee breaks” while at work, which relaxes them. Who would have forgotten the student days, when numerous coffee cups kept them awake until late nights just before examinations? Coffee drinking is supposed to increase alertness and concentration. The effects are mainly related to caffeine contained in the coffee.

Health-Related Benefits of Drinking Coffee

1. Lower risk of diabetes: In a Dutch study done on 40,000 people, it was found that drinking at least 3 cups of coffee or tea per day reduced the risk of developing diabetes by 42%. (Diabetologia 2009). The anti-diabetic effects are related to polyphenols found in coffee.

2. Lower risk of coronary heart disease: Moderate habitual coffee consumption (3-4 cups per day) lowers the risk of coronary heart disease, especially in women. (International Journal of Cardiology)

3. Coffee improves headaches and migraine, if taken alone or along with other painkillers.

4. Lower risk of brain stroke: Middle aged people in Japan, who drank 3 or more cups of coffee per day had lower rates of silent brain infarctions (strokes without symptoms, picked up on MRI scan of brain). Lesser brain infarctions would also lead to lesser incidence of dementia. (Journal of Stroke and Cerebrovascular Diseases, 2016)

3 or more cups of coffee intake per day reduced the risk of brain stroke (despite smoking tendency in coffee drinkers). A lower incidence of heart failure, diabetes and hypertension was also observed. (Nutritional Neuroscience, 2015)

5. Reduced risk of Alzheimer’s disease: Alzheimer’s disease is the commonest cause of dementia (memory loss and loss of other higher mental functions) in the world. Based on the meta-analysis of 11 research studies, it was found that higher coffee consumption reduced the risk of Alzheimer’s disease. (Nutrition, 2015)

6. Reduced risk of Parkinson’s disease: Parkinson’s disease is the commonest cause of movement disorder, characterized by tremors, rigidity and slowness of movements. Based on meta-analysis of 26 studies, increased caffeine/coffee consumption was associated with reduced risk of Parkinson’s disease. (Journal of Alzheimer’s Disease, 2010)

7. Reduced risk of multiple sclerosis: Researchers in USA and Sweden have found that drinking at least 900 ml (six cups) of coffee per day has protective effects against multiple sclerosis. Caffeine has neuroprotective properties and suppresses inflammation. (JNNP, 2016)

8. Reduced risk of depression and suicide: A meta-analysis of 11 studies showed a protective effect of coffee against depression. The relationship between coffee intake and depression was linear; for each cup/day increase in coffee intake, the risk of depression reduced by 8%. (Australia NZ Journal of Psychiatry 2016)

In addition, increased coffee consumption was also associated with reduction in incidence of completed suicides. (World Journal of Biol Psychiatry, 2014)

9. Reduced risk of cancer: Various studies have shown that regular coffee consumption is associated with lower risk of cancers. 5 or more cups per day reduced the risk of colorectal cancer (Oncotarget, 2016). Other studies have shown reduced risk of cancers of oral cavity, pancreas, urinary bladder, breast, uterus, and liver among regular coffee drinkers.

10. Lesser incidence of erectile dysfunction: Coffee can provide a boost to sexual health too. Men with coffee intakes of 2-3 cups of coffee/ day reported significantly lesser incidence of erectile dysfunction, as compared to those with no coffee intake or only 1 cup/day. (PLos One, 2015)

11. Lower death rates: Regular intake of coffee can increase longevity and prevent deaths too. Recent research has shown that people drinking 2-5 cups of coffee/day had significantly lower deaths from heart disease, chronic lung diseases, diabetes, pneumonia and influenza, and intentional self-harm. Coffee may reduce mortality risk by favorably affecting inflammation, lung function, insulin sensitivity, and depression. (American Journal of Epidemiology,

Possible Health Hazards of Coffee Drinking

1. Poor control of BP in patients with hypertension:  A recent study showed that older people with hypertension, who consumed 3 or more cups of coffee per day, had higher BP (systolic and diastolic). Coffee drinking, however, does not lead to an increased risk of developing hypertension (in people with normal BP).

2. Increased cholesterol levels: Drinking unfiltered or boiled coffee may cause an increase in the levels of LDL cholesterol and triglycerides.

3. Increased risk of coronary heart disease: Drinking 3 or more cups of Italian-style coffee (espresso or mocha) is associated with increased risk of coronary heart disease. (PLoS One, 2015). This effect was independent of cholesterol levels, as the cholesterol levels did not increase in this study.

4. Sleep problems: Caffeine is a brain stimulant and after consuming it, people feel alert. People sensitive to the stimulant effects of caffeine may not get proper sleep, if they drink coffee close to bedtime. Since, the effect of coffee may last for 5-6 hours, people sensitive to it should avoid coffee after 6 PM.

5. Not recommended for children: Coffee suppresses appetite, and may cause children to eat less. Also, after having coffee, children feel full, and avoid nutritious foods such as milk.

6. Pregnant and nursing women should have coffee in moderation: There is no restriction of coffee in pregnant or nursing mothers. However, they should restrict the coffee intake to 2-3 cups per day.

So, what is the final take home message?

1. Coffee is good for health, and can be safely consumed by adults.

2. For optimum benefits, it should be restricted to 2-5 cups per day.

3. The maximum safe limits for caffeine/coffee intake is 200 mg in one sitting (around 2½ cups of coffee) or 400 mg daily (around 5 cups of coffee). 

4. Coffee (without sugar and milk) has zero calories; and hence, people on strict diet too can freely have coffee.

VEGETARIAN DIET INCREASES THE RISK OF CANCER AND HEART ATTACK; AND REDUCES FERTILITY

VEGETARIAN DIET INCREASES THE RISK OF CANCER AND HEART ATTACK; AND REDUCES FERTILITY

A recent study done at Cornell University in US has shown a higher risk of cancer and heart attacks in people eating pure vegetarian food for generations. Scientists have found that long-term vegetarianism can lead to genetic mutations, which increase the risk of heart disease and cancer.

Traditionally, red meat is known to increase the risk of colorectal (intestine) cancer, however, a recent research found the reverse, a 40% higher cancer risk among vegetarians!

This study compared two sets of people- meat eating people from Kansas (USA) and vegetarian people from Pune (India).

Long term vegetarian people were found to have genetic mutation that resulted in rapid metabolism of plant fatty acids, leading to increased amounts of arachidonic acid (which increases inflammation) and reduced production of protective omega 3 fatty acid. A shift of diet from fish (rich in healthy omega 3 fats) to vegetable oils (rich in less healthy omega 6 fats) has compounded the problem.

This study has clearly shown the higher risks of heart disease and cancer in pure vegetarian people. The message to vegetarians is clear- either eat fish or use olive oil (low in omega 6) if you cannot eat fish.

Previous studies have shown other problems with vegetarian diet:

1. Low sperm count leading to reduced fertility,

2. Low fertility could also be related to intake of pesticides (used in fruits and vegetables),

3. Vegetarians are also more prone to deficiencies of iron and vitamin B12.

4. One study found lower bone mineral density in vegetarians.

Finally, there is some good news for vegetarians. All is not gloomy. Research has also shown lower risk of diabetes, stroke and obesity among vegetarians as compared to non-vegetarians.

TIPS FOR GOOD AND RELAXING SLEEP (on WORLD SLEEP DAY)

TIPS FOR GOOD AND RELAXING SLEEP

Today is World Sleep Day (celebrated on Friday of second full week in March).  You must be wondering why should we celebrate World sleep day. This is because about 45% of population suffers from one form of sleep disorder or other or are sleep deprived. Sleep problems are not only associated with un-refreshed feeling, but are also associated with major health hazards. So, the World sleep day is aimed at raising awareness about benefits of good sleep and ways to ensuring a good sleep. This year’s slogan for World sleep day is “Good sleep is a reachable dream”.

Normal Sleep

     1. Normal sleep duration is 7-9 hours in adults (10-11 hours in 6-12 year olds; 9 hours in teenagers)
     2. Natural sleep occurs at nights, as melatonin (sleep hormone) is released during nights (when there is no light)
     3. Adults need to sleep only once (at nights). This is called monophasic sleep. People older than 60 may have biphasic sleep (in addition to nights, they may sleep in afternoons too). Newborn babies and infants may have polyphasic sleep (they sleep and get up multiple times).
     4. The best time to go to bed is between 9 PM to 11 PM and the best time to get up is between 5 AM to 7 AM. It should be made a habit to go to sleep and awaken at the same time everyday to avoid sleep problems.
     5. People who work until late evenings may benefit from a short post-noon sleep, called as siesta or power nap. Typically, it should not last more than 15-20 minutes. Siesta energizes the individual improving their work efficiency.

Functions of Normal Sleep
1. Sleep is restorative in nature and makes us fresh and energised to do the day’s work,
2. Growth hormone (GH) is released at nights during sleep. GH secretion may get affected in nights shift workers (and day sleepers). (Prolactin and testosterone are also maximally secreted at nights)
3. Consolidation of memory occurs during sleep. So, it is a better habit to have a good nights’ sleep for better memory, rather than burning midnight oil! The best long term memory is achieved when learning is followed by sleep within three hours.

Risks and Hazards of Sleeping Less
1. Attention and concentration are impaired the day after less sleep. This could result in driving errors, poor efficiency at school or work, as the case may be,
2. Some people complain of general tiredness or heaviness of head/headache after sleeping less,
3. Memory impairment may occur in people sleeping less,
4. Increased irritability and behavioral problems are seen in sleep deprived people,
5. Less sleep may make you fat and lead to obesity,
6. Increased incidence of diabetes mellitus, hypertension, cancer, stroke and coronary artery disease is seen in people sleeping less,
7. Lack of sleep kills sex drive,
8. Less sleep may lead to depression and anxiety; also, people with depression and anxiety sleep less,
9. Lack of sleep leads to skin ageing, and makes it lackluster. Dark circles may form under the eyes.
10. There is also an association between less sleep and higher death rates. Reducing sleep duration from 7 to 5 hours on a regular basis may double the risk of death, mostly from cardiovascular causes.

Tips for Ensuring Good and Sound Sleep
1. Have a light dinner and avoid heavy meals at nights. Eat at least two to three hours before sleeping time. A full stomach may cause sleep disturbance. Late dinners may cause acid reflux in the stomach,
2. Avoid tea, coffee other stimulant drinks at nights, as it may cause less sleep,
3. Avoid smoking at all times, especially at nights,
4. Maintain a good sleep hygiene (try to sleep and wake up at the same time every day)
5. Avoid night shift duties and doing duties in changing shifts (occasional night duty is alright),
6. Avoid frequent travels to places with different time zones (this can lead to jet lag and impaired sleep),
7. Avoid arguments and heated discussions just before sleep,
8. Avoid watching negative news on TV about various crimes, etc at nights. Instead it may be better to listen to some soothing music or read a relaxing novel.
9. Exercise in the evenings improve night’s sleep quality,
10. A glass of milk would also improve sleep,
11. The bedroom should be used only for sleep (and sex) and office work should not be brought to bedroom.
12. It is better to keep the phones and other gadgets away during sleep, and keep them in silent mode
13. Sleep is better in dark, so, ensuring that would improve sleep quality.
14. Also, maintain a good ambient room temperature. Too hot or too much cold temperature may hamper good sleep.
15. Avoid taking sleeping pills, as they can lead to addiction or dependence on them. After that, you would not get sleep without them and over a period of time, much higher doses of sleeping pills would be needed.
