It’s especially important during the severe heat waves and power cuts we are currently experiencing. From losing weight to dehydration affecting brain function and mood, here’s what you need to know.

Drinking water aids digestion

Water will not dilute your digestive juices or interfere with digestion. In fact, drinking water during or after a meal actually aids digestion. Water and other liquids help break down food so that your body can absorb the nutrients.

Maximise your physical performance

If you you do not stay hydrated while exercising, your physical performance will decrease. This is especially important during intense exercise or high temperatures. Losing as little as two percent of your body’s water content can significantly impair physical performance.

Hydration has a huge effect on brain function

Studies show that even mild dehydration can impair many aspects of brain function. It can affect mood, memory, energy levels and overall brain performance.

Drinking water may help to prevent and treat headaches

Dehydration can trigger headaches and migraines in some people. Several studies have shown that water can relieve headaches in those who are dehydrated. However, this depends on the type of headache.

Drinking more water may prevent and relieve constipation

Drinking a lot of water can help manage constipation, especially in people who generally do not drink enough water. Water softens stool, which helps prevent constipation. Carbonated water shows particularly promising results for constipation relief, although the reason is not entirely understood.

Water helps prevent and alleviate hangovers

Alcohol is a diuretic, so it makes you lose more water than you take in. This can lead to dehydration. Although dehydration is not the main cause of hangovers, it can cause symptoms like thirst, fatigue and headache. Drink a glass of water between drinks and at least a glass before going to bed.

Drinking more water can help you lose weight

Drinking lots of water can help you lose weight. This is because water can increase satiety and boost your metabolic rate. Drinking two litres of water per day can increase your total energy expenditure by up to 96 calories per day. Drinking water half an hour before meals is the most effective.

Drinking water may help prevent kidney stones

Higher fluid intake increases the volume of urine passing through the kidneys, which dilutes the concentration of minerals, so they are less likely to crystallize and form clumps. Water may also help prevent the initial formation of stones.
