Hey loves,

I get the struggle: summer heat, being low on energy, feelings of aggression and mood swings, sweat and dehydration.

While the summer days are the happiest full of vitamin D, serotonin and good times, your body does have to work extra hard to cool you down.

It is for this reason that I have created this guide on how to adjust to the heat, remain safe and still reach your fitness goals this summer.

How Heat Impacts Training

This is what happens to your body when you train during high heat:

• Higher heart rate
• Increased sweat
• Faster dehydration
• Greater fatigue

Why Strength and Endurance feel Harder

In the heat, your body works harder to stay cool by redirecting blood to the skin and making you sweat, which leaves less energy and oxygen for your muscles.

You end up losing fluids and electrolytes, your heart rate spikes, and your core temperature rises– making both strength and endurance feel harder.

Even light workouts can feel intense because your body is under double the amount of stress.

Signs your Body is Overheating (and When to Stop)

• Excessive sweating that suddenly stops
• Dizziness or lightheadedness
• Rapid heartbeat or breathing
• Headache or nausea
• Muscle cramps
• Weakness or extreme fatigue
• Confusion or disorientation
• Skin that feels hot, red, or dry
• Chills or goosebumps during heat

When to Stop:

• If you feel dizzy, nauseous, or confused– stop immediately
• If your heart is racing or you feel faint- get to a cool place
• If sweating stops suddenly or you get chills- it’s a medical red flag

2. What to Wear: Smart Summer Training Outfits

• Breathable, moisture-wicking fabrics (avoid cotton)
• Light colors over dark
• Supportive sports bras that handle sweat

Best Hairstyles for Sweaty Weather:

1) Slick High Bun

2) Bubble Ponytail

3) Braided Crown or Halo Braid

Skincare tips if you’re acne-prone in the heat:

Check out my previous blog post for a Summer Guide To Working Out In Humid/Warm Weather.

• Cleanse Gently But Consistently

Twice is more than enough, make sure to use a cleanser with gentle ingredients or salicylic acid, mandelic acid or zinc to deeply cleanse without irritating your skin barrier.

• Lightweight Hydration is Essential

You should never skip moisturizer, even if it’s humid or sunny. Moisturizer is essential for hydrating your skin and providing a rich barrier for it to heal and recover.

I recommend opting for a gel-based or water-based formulas, choose ingredients like hyaluronic acid or niacinamide.

• Target Breakouts Without Burning Your Skin

Spot treat with benzoyl peroxide, salicylic acid, or azelaic acid (don’t layer them all at once). Use tretinoin only at night, and buffer with moisturizer if needed.

Avoid harsh scrubs, astringents, and overuse of acids during the day.

• Never Skip Sunscreen, Even with Acne

The combination of heat and UV leads to more inflammation and clogged pores.

Make sure to use an oil-free, non-comedogenic SPF 30+ with a matte finish.

Look for: ingredients like silica or niacinamide for oil control.

Faves: Eucerin Oil Control SPF 50, Pharmaceris Sebo-Protect, or La Roche-Posay Anthelios Dry Touch.

• Change Pillowcases & Wipe Sweat Often

Use clean towels, microfiber face cloths, or oil-blotting sheets throughout the day.

Avoid letting sweat dry on your skin (carry rosewater mist or micellar wipes).

Avoid:

• Heavy makeup or anything occlusive (like balms, oils) during the day.
• Skipping moisturizer (even if you’re oily and it’s humid).
• Touching your face, especially when sweating.

Lifestyle tips:

• Drink plenty of water.

• Avoid dairy and excess sugar if your acne flares with diet.

• Eat cooling, anti-inflammatory foods (think cucumber, mint, watermelon and zinc-rich meals).

3. Best Times to Work Out in the Summer

During the summer months, try to follow the Golden rule which is to train early morning or post-sunset.

This will ensure that you don’t overheat or become susceptible to skin issues like allergies and rashes from sweat.

Make sure to avoid peak UV and heat hours, this tends to be from 11 AM–4 PM. I also highly recommend training indoors instead of outdoors to minimize contact with the sun.

4. Hydration & Electrolytes: Not Optional

To maintain your body’s temperature and coolness , plain water isn’t always enough. Make sure to look out for these signs of dehydration to assess your body’s hydration levels during the summer:

• Dry mouth or sticky saliva
• Dark yellow urine or decreased urine output
• Thirst
• Dry skin
• Fatigue or low energy
• Headache
• Dizziness or lightheadedness
• Muscle cramps
• Constipation
• Signs of dehydration

If you find that you are dehydrated during the summer, make sure to increase hydration and consider the use of electrolyte tablets or powders. Here is how and when to use them:

Use them during intense workouts. For instance, if you are doing an HIIT, a heavy leg day or endurance training.

You can take them before (will prevent cramping and fatigue), during (keeps energy stable) or after your workout (replenishes lost minerals).

You can take them even if you are not working out and as long as the weather is hot. Furthermore if you are exhibiting signs of dehydration such as vomiting or diarrhea, then electrolytes can really help.

Finally, aim for taking them once or twice per day if you’re sick and try to avoid overuse as this can do more harm than good.

Finally, traveling or having jet lag are also situations when one can benefit from taking electrolytes.

So, how do we use them?

Dissolve the electrolytes in water, usually 500 ml to 1 liter is the recommend amount.

Make sure your electrolytes are not mixing in with any sugar or artificial additives.

Summer-friendly Pre-workout Snacks:

• Watermelon: rich in water and L-citrulline (may be able to help blood flow)
• Pineapple: natural sugars + bromelain (anti-inflammatory)
• Banana: potassium boost for muscle function
• Dates: simple carbs for quick fuel
• Berries: antioxidants + carbs, low glycemic

Fluids + Electrolytes (Take 30 mins before)

Keeps you hydrated and supports muscle function:

• Coconut water: natural electrolytes + sugar = great pre-workout drink
• Coconut water + chia seeds: for added fiber and slow energy release
• Electrolyte drink + fruit: combo of hydration and fuel

Fruit-Based Combos

Great if you want something more substantial but still light:

• Banana with almond or peanut butter
• Frozen mango chunks with Greek yogurt
• Date + almond butter bites
• Rice cake with sliced strawberries + a drizzle of honey

Smoothies (Take 45–60 mins before workout)

Refreshing and balanced with carbs, a bit of protein, and hydration:

• Watermelon + mint + ice + a scoop of BCAAs or collagen
• Banana + coconut water + a handful of oats
• Pineapple + cucumber + lemon + protein powder

5. Adjusting Your Training: Still Strong, Just Smarter

Contrary to your body’s distress signals, you don’t need to “go harder” in heat. You should aim for lower reps, longer rests and focus more on your form.

Make sure to try to train indoors to avoid the sun’s harsh UV rays and intensity.

6. Dealing With Sweat & Skin: Real Talk

Sweat doesn’t equal fat loss, it equals fluid loss. Don’t try to accelerate the amount of sweat that your body is producing just because you think it might be “burning off more calories”.

How to Protect your Skin (especially face/back acne)

Tips:

Change clothes immediately, wipe down gear, and make sure to exfoliate regularly.

Here are a few of my recommended cooling go-tos for the hot summer months:

Mario Badescu Facial Spray

Eau Thermale

7. Cooling Down Properly: Underrated but Essential

Make sure to include a post-workout cool-down session even more religiously in the heat. Go for a short walk after your workout and include some gentle stretching.

Use a cold towel or mist after training and/or take a cold shower after your workout.

8. How to Stay Motivated When It’s Too Hot to Function

How about we adopt a summer mindset shift of maintaining vs pushing to reach our objectives. Make sure to focus on consistency over perfection as well.

Another great way of staying motivated while it is very hot outside is training for mental health, mood, and confidence.

Use your summer body as motivation to take care of it instead of destroying it.

Conclusion: Train With the Season, Not Against It

You really don’t need to skip workouts, you just have to train smart. You are powerful, adaptable and capable of having the best summer while reaching hope fitness goals.
