Today we are going to do some ol' fashioned myth busting when it comes to exercise and eating healthy in the heat. And give you some healthy tips along the way!
#1. Is it really hot enough to fry an egg? No, not really. And seriously, would you even want to eat the egg? Stick to frying your eggs in a pan instead.
#2. Does the heat actually make you more tired? Yes. Heat is very draining on your body and it uses a lot of your active energy just to try and cool your body down. Which means if you have air conditioning you will be able to sleep better at night.
It isn't just the heat however - it is also the humidity. Which means a dehumidifier in your bedroom can also help you to sleep better. And better sleep = more energy the next day and less likely to binge on sugary foods to boost your energy levels.
#4. However, heat exhaustion doesn't mean you should jump in a cold shower or a pool. The shock could knock you unconscious. Your goal should be to SLOOOOOOWLY lower your body temperature back to normal. So a dip in a cool pool - not a cold one - will help. A cool / luke warm shower is also good. Drinking lots of water (not too much all at once) will also help. Avoid alcohol and caffeine, they will just dehydrate you further.
#5. Avoid very large meals on a hot day. Binging on food will just make you more tired. Your body is already working hard to maintain your body temperature, so digesting a big meal will just put more stress on it. Aim for smaller, lighter meals - and eat snacks in-between meals.
#6. When running / jogging don't drink ice cold water. Instead drink cool water that is only moderately cold. The reason is because your body has to expend energy to warm that water up. The lost energy then makes you feel more tired than you would normally be. By drinking only moderately cool water you don't feel the energy drain as much but are still getting the cooling effect. Some marathon runners prefer to drink water which is luke warm / room temperature that way they are minimizing their energy drain as much as possible and only want the water for hydration, not for cooling them down.
#8. A handy trick is to exercise AFTER the sun goes down. You can download a smartphone app that will tell you when sunrise and sunset is in your area or check it online. (I personally use one which tells me sunrise, sunset, a detailed hourly weather forecast and the weather forecast for the coming week.)
#9. If doing any kind of weight training outside on a hot day it is best to have a partner if possible. Long list of variety of safety reasons. And the list grows longer if you are older and / or unfit. Exercise caution.
#10. Sweating a lot doesn't burn more calories. It just means your body is overheating and trying to cool down. If you feel too hot you won't be able to exercise as hard. You can exercise much harder in cooler conditions because your body doesn't have to expend so much water, sodium and energy trying to cool you down.
#12. If you're tempted for a beer on a patio, try to stick to just one beer. None is better, but if you fall to temptation try to limit yourself to one and then have a glass of water with it. Same goes with coffee and other caffeine drinks. Alcohol and caffeine dehydrates you because you end up using more water from your body just trying to flush the toxins from your system. (Which is why you will feel the need to urinate later after drinking alcohol or caffeine.) Exercising immediately after having alcohol is not recommended, but if you do try to rehydrate yourself by drinking a fair amount of water before, during and after the exercise.
#13. Your body adapts over time to hot weather. It is why we get sunburns on our arms for example and later our arms become more resistant to sunburns. It is in our genetics that we adapt to summer by getting sunburns a couple times and by the time we have a good tan going we don't burn as easily - but you can still get a painful sunburn if you aren't careful! So use sunscreen, wear a hat and avoid long exposure to the sun.
#14. Your blood vessels and sweat levels also adjust to the weather. You will start craving more salty foods and this is normal - the sodium in the salt replenishes your ability to sweat and keep yourself cool.
Women who wear antiperspirant regularly have significantly higher chances of developing lymph node and breast cancer. In contrast most men use deodorant instead, which doesn't prevent sweating and instead just masks the smell - and thus men have significantly lower chances of lymph node and breast cancer because they aren't using antiperspirants as much as women do. This doesn't mean men cannot get cancer in those body parts, it just means that most men don't use antiperspirant and thus have lower chances. A man who does use antiperspirant regularly will have the same chance of developing lymph node and breast cancer as a woman who uses antiperspirant regularly.
Also your body is going to sweat anyway. Swiping some toxic chemicals on your armpits isn't going to stop you from sweating from head, neck, chest, arms, belly, back, legs and so forth. In its efforts to cool your body down your body will simply sweat from all available pores anyway.
